Splits documents into fixed-size chunks and embeds each directly. When parser sections are available, chunks are created section-by-section instead of flattening the whole document. +- **parent_child** - Two-level chunking. Splits into large parent chunks, then smaller child chunks. Embeds child chunks but returns parent text for richer context. When parser sections are available, sections are used as natural parent boundaries. +- **qa** - LLM-generated Q&A pairs. Chunks text, uses an LLM to generate question-answer pairs per chunk, and embeds the questions. When parser sections are available, Q&A generation also becomes section-aware. + +## Query Rewriting + +- **hyde** - Hypothetical Document Embedding. Generates a hypothetical answer to the query, then embeds that answer for retrieval. +- **multi_query** - Generates 3 query variants, searches with each, and merges results by score. +- **step_back** - Generates a more abstract question and searches with both the original and abstract queries. + +## Pairing With GeneralParsers + +GeneralParsers is currently the recommended parser for LangRAG because it can provide: + +- cleaner PDF extraction +- structured sections +- table-preserving text +- document-level metadata +- optional OCR and image descriptions via a vision model + +LangRAG consumes those parser outputs directly during ingestion, which generally produces better chunks and better retrieval quality than the fallback parser. + +## Observability Page + +LangRAG includes a WebUI Page named **Observability**.

For +these cases `all_relevant@k` is more informative than `hit@k`, because +retrieving only one of two gold documents is insufficient for the downstream +answer. diff --git

+This plugin is not trying to dump the entire chat history into context. Instead, it splits long-term memory into two layers with different storage and retrieval behavior: + +- **L1 core profile**: stable, low-frequency facts such as names, preferences, identity, and long-lived notes +- **L2 episodic memory**: time-sensitive and situational facts such as recent events, plans, and experiences + +This split exists for a reason: + +- Stable profile data is cheap and reliable to inject into the system prompt +- Episodic memory keeps growing over time, so it should be retrieved on demand instead of fully injected every turn +- Agents should update stable profile facts differently from event-like memories + +## How This Differs From OpenClaw-Style Personal Assistant Memory + +Recently, a lot of agent systems have discussed designs like OpenClaw: long-term memory stored primarily as user-readable text files such as `MEMORY.md`, combined with summaries, reflection, and light retrieval logic. + +That approach has clear strengths: + +- memory is fully transparent to the user +- plain text is naturally easy to back up, sync, and version-control +- it fits single-user, single-assistant, high-continuity personal workflows very well +- when memory volume stays small, full-text understanding can indeed be "good enough" + +But LongTermMemory in LangBot is solving a different problem. Typical LangBot deployment looks more like: + +- one bot serving multiple group chats and private chats +- one plugin instance handling multiple sessions and multiple speakers +- memory including shared group context, current-speaker profile, and session-level episodic facts +- explicit isolation boundaries between sessions, bots, and speakers + +Because of that, we did not adopt a "single text file as the source of truth" design. We chose a layered architecture that better matches LangBot's multi-session runtime model. + +### What OpenClaw-like memory is optimized for + +Abstractly, that design is optimized for: + +- **single-user personal assistants** +- **human-readable text as the primary long-term memory form** +- **transparency, editability, and narrative continuity** +- **an assumption that memory size stays manageable and the user is willing to curate it directly** + +That is a very reasonable fit for personal AI companions, research copilots, and private assistant workflows. + +### Why LangBot does not simply copy that model + +LongTermMemory is designed around different operating constraints: multiple sessions, multiple speakers, explicit isolation, controlled injection, and retrievable episodic recall. + +If we turned long-term memory into one narrative file like `MEMORY.md`, several problems would appear quickly: + +- **Isolation would become hard** + - how should memories from group A, group B, and private chat C coexist safely? + - how do you cleanly separate one speaker's stable profile from a shared narrative log? +- **Injection granularity would become unstable** + - system prompts need stable profile state, not an entire chronological diary + - automatic recall needs the most relevant memory slices for the current query, not the whole story +- **Multi-user boundaries are first-class in LangBot** + - in a personal assistant, "the user" is usually one person + - in LangBot, current speaker, current session, and current bot all matter +- **Automatic injection and active retrieval are different needs** + - stable profile data should be injected consistently + - episodic memory should be retrieved selectively + - forcing both into one text-only memory shape becomes awkward + +### The tradeoff we made + +So the LongTermMemory design is essentially this tradeoff: + +- **What we borrow from that philosophy** + - memory should not be treated as only a black-box vector store + - stable profile, temporal memory, and long-term behavior adjustment all matter + - not everything should be dumped into context every turn + +- **Where we deliberately differ** + - we do not use a narrative text diary as the only memory source of truth + - we split stable profile and episodic memory explicitly + - we prioritize isolation across sessions, speakers, and bots + - we let L2 memory plug naturally into LangBot's KB / retrieval system instead of relying only on full-text reading + +In short: + +- OpenClaw is mainly answering: "How should a personal assistant keep readable, editable, reflective long-term memory?" +- LongTermMemory is mainly answering: "How should a bot working across groups and private chats keep stable profile state and retrievable experience memory under explicit isolation rules?" + +Neither direction is universally "better". They optimize for different products and different failure modes. + +## Design + +This plugin intentionally stays close to LangBot's existing extension points instead of requiring custom core patches. + +- L1 profile is stored in plugin storage as JSON +- L2 episodic memory is stored in the vector database +- Memory retrieval is enabled per pipeline by attaching this plugin's KnowledgeEngine +- The plugin currently assumes a single memory KB per plugin instance and isolates memory by metadata + +The current implementation is built around the existing LangBot and SDK APIs. If LangBot later adds more explicit memory-oriented APIs, session identity APIs, or KB registration APIs, the plugin could be simplified, but the current architecture would still remain valid. + +### Vector Database Backend Compatibility + +L2 episodic memory relies on arbitrary metadata fields (`user_key`, `episode_id`, `tags`, `importance`, etc.) for isolation and filtering. Not all LangBot vector database backends support arbitrary metadata: + +| Backend | Arbitrary metadata | LongTermMemory support | +|---------|-------------------|----------------------| +| **Chroma** (default) | Yes | Full support | +| **Qdrant** | Yes | Full support | +| **SeekDB** | Yes | Full support | +| **Milvus** | No (fixed schema: `text`, `file_id`, `chunk_uuid`) | Not supported | +| **pgvector** | No (fixed schema: `text`, `file_id`, `chunk_uuid`) | Not supported | + +Milvus and pgvector use a fixed column schema and silently drop metadata fields they do not recognize. This means metadata-based isolation (`user_key` filtering) and episodic memory commands (`!memory list`, `!memory forget`, `!memory search`) will not work correctly on these backends — filters will be ignored and queries may return unscoped results. + +If you need to use LongTermMemory, use Chroma, Qdrant, or SeekDB as your vector database backend. + +After configuring the memory knowledge base, run `!memory health` in a pipeline that uses that knowledge base. The health check verifies that the KB is present, active in the current pipeline, has an embedding model, and can use metadata filters to keep two temporary `user_key` probe records isolated. If this command reports metadata-filter leakage, the backend is not safe for scoped LongTermMemory recall. + +## How It Works + +An end-to-end long-term memory flow has four main parts: + +### 1. L1 profile writes + +- The agent uses `update_profile` to write stable facts +- Data is stored in plugin storage as structured JSON +- Profiles are stored at either `session` or `speaker` scope + +### 2. L2 episodic writes + +- The agent uses `remember` to write event-like memory +- Each memory carries metadata such as timestamp, importance, tags, and scope +- Those memories are embedded and stored in the vector database through the plugin's KnowledgeEngine + +### 3. Automatic pre-response injection + +- During `PromptPreProcessing`, the EventListener resolves the current session identity +- For L1: + - it loads the shared session profile + - it loads the current speaker profile + - it injects both, along with current speaker identity, into `default_prompt` +- For L2: + - it runs one episodic retrieval using the current user message + - retrieved memories are injected as factual context blocks + +So both L1 and L2 enter the model context before answer generation, but in different forms: L1 as system prompt memory, L2 as retrieved context. + +### 4. Active lookup and debugging + +- If automatic injection is insufficient, the agent can call `recall_memory` +- For inspection and debugging, you can use `!memory`, `!memory profile`, `!memory search`, `!memory list`, and `!memory forget` +- `!memory export` exports only the current scope's L1 profiles for backup or migration + +## Memory Write Policy + +Write L1 profile memory when the fact is stable, low-frequency, and currently valid: + +- names, identities, long-term preferences, communication style +- durable speaker facts in private chat, such as "Alice prefers concise technical answers" +- durable group/session conventions, such as "This group coordinates the LangBot release" +- explicit corrections to current stable facts + +Write L2 episodic memory when the fact has time, history, or situational value: + +- plans, deadlines, recent status, decisions, and events +- private chat example: "Alice said her Tokyo flight is next Tuesday" +- group chat example: "Bob agreed to own the database migration this week" +- correction history when the timeline matters + +Write nothing when the content is not useful or should not be stored: + +- one-off greetings, jokes, small talk, or facts only needed for the current answer +- secrets, credentials, API keys, one-time codes, and private tokens +- unconfirmed sensitive claims, third-party private gossip, or harmful inferred labels + +Correction rule: update L1 for the corrected current fact. If the correction itself is historically important, also write an L2 episode describing the correction. Do not keep contradictory L1 profile values active in parallel. + +## Relationship With AgenticRAG + +When AgenticRAG is enabled together with LongTermMemory: + +- LongTermMemory removes its own memory KB from naive RAG pre-processing +- automatic L2 recall is still handled by LongTermMemory itself +- the same memory KB can still be queried explicitly through AgenticRAG's `query_knowledge` tool + +This avoids duplicate recall while preserving both paths: + +- automatic memory recall +- deeper agent-initiated retrieval when needed + +## Why There Is No Agent-Side Metadata Filter + +The underlying runtime can support metadata filtering, but this plugin does not expose arbitrary raw metadata filters to the agent flow today. + +Reasons: + +- Different knowledge engines and vector backends do not share one unified metadata schema +- Filter field names, value formats, and supported operators may differ +- The agent currently has no stable schema source for constructing reliable filters + +If LangBot later provides a unified way to describe filterable metadata fields per knowledge base, agent-side metadata filtering can be added. + +This plugin does provide a controlled recall tool surface for its own stable memory schema. That tool supports selected filters such as speaker and time range, without exposing free-form backend-specific filter syntax to the model. + +## Isolation Model + +Two isolation modes are supported: + +- `session`: each group chat or private chat has independent memory +- `bot`: all sessions under the same bot share memory + +In the current deployment model, this is generally sufficient because plugin instances are usually bound to a specific LangBot runtime/bot environment. + +## Isolation Rules In Detail + +There are two related but slightly different scope concepts in this plugin: + +- **session_name**: the conversation identity passed through the current query / retrieval path, formatted as `{launcher_type}_{launcher_id}` +- **session_key**: the plugin's internal L1 storage key. When `bot_uuid` is available, it becomes `{bot_uuid}:{launcher_type}_{launcher_id}`; otherwise it falls back to `{launcher_type}_{launcher_id}` +- **scope_key / user_key**: the actual key used for profile storage or L2 retrieval isolation + +### How L1 profiles are isolated + +L1 profiles are always stored within the current conversation scope: + +- `session profile` + - shared profile for the current conversation + - useful for group-level or conversation-level stable context +- `speaker profile` + - stable facts about the current speaker + - useful for person-specific preferences, identity, and notes + +Because of that, `!memory export` exports only the profiles that belong to the current `session_key`, not every profile in the whole plugin instance. + +### How L2 episodic memory is isolated + +L2 memories are written into the vector store with isolation metadata, then filtered at retrieval time: + +- `session` + - memories from group A are not recalled in group B + - memories from one private chat are not recalled in another +- `bot` + - all sessions under the same bot share one episodic memory space + - useful when you want cross-session long-term experience sharing + +When `sender_id` is available, the plugin can also prefer speaker-related memories before widening to the broader scope. + +### Why L1 and L2 isolation are not exactly the same + +That is intentional: + +- L1 behaves like stable profile state, so precise session / speaker storage makes sense +- L2 behaves like a retrievable experience base, so metadata-based filtering is the more scalable model +- this keeps L1 precise and L2 flexible + +## How To Use + +1. Install and enable the plugin. +2. Create one memory knowledge base with this plugin's KnowledgeEngine. +3. Configure: + - `embedding_model_uuid` + - `isolation` + - optional `recency_half_life_days` + - optional `auto_recall_top_k` +4. Let the agent use: + - `remember` for events, plans, and episodic facts + - `recall_memory` for active memory lookup when automatic recall is insufficient + - `update_profile` for stable preferences and profile data + - `forget` to delete a specific episodic memory by ID +5. Run `!memory health` in a pipeline that includes the memory KB. Treat `ERROR` as a setup problem before relying on scoped recall. +6. Use `!memory`, `!memory profile`, `!memory search `, `!memory list [page]`, `!memory forget `, `!memory export`, and `!memory consolidate preview` to inspect behavior. `!memory list` and `!memory search` show active episodes by default; add `--include-superseded`, `--include-archived`, or `--status ` when explicitly inspecting hidden lifecycle states. + +## Episode Lifecycle + +L2 episodes carry a lifecycle `status` metadata field: + +- `active`: default state for new episodes and eligible for normal recall +- `superseded`: replaced by a newer correction or fact update +- `archived`: retained for history, excluded from normal recall +- `deleted`: reserved for tombstones or future audit workflows + +Existing records without `status` are treated as `active`, so no migration is required. Automatic recall and `recall_memory` only return active episodes by default. Correction-style writes mark similar older active episodes as `superseded`, which keeps them inspectable through explicit management commands without letting them compete with current memory. + +## Audit Log + +Memory-changing operations write scoped audit entries to plugin storage, not to the L2 vector database. Audit entries include the operation, target, scope key, user key, sender identity when available, timestamp, query id, and a short summary. + +Use `!memory audit [page]` to inspect recent entries for the current scope, or `!memory audit export` to export only the current scope's audit log as JSON. + +## Managing Hidden Episodes + +Use `!memory show ` to inspect one episode, including status, sender, source, tags, importance, and supersede metadata. Use `!memory superseded [page]` and `!memory archived [page]` to inspect records hidden from normal recall. Use `!memory archive ` to hide an active episode without deleting it, and `!memory restore ` to make an archived or superseded episode active again. Archive and restore operations write audit entries. + +## Memory Consolidation + +Use `!memory consolidate preview` to inspect cleanup candidates for the current scope. Preview never modifies memory. It reports candidate episode IDs, a deterministic summary episode proposal, possible profile updates, episodes that would be archived, and risk notes. + +Use `!memory consolidate run` only after setting `consolidation_enabled=true` on the memory knowledge base. Run applies only the current `user_key` scope. It can archive selected active or superseded episodes and write one summary episode tagged `consolidation` and `summary`. Every archive and summary write creates scoped audit entries. Profile update application is disabled by default through `consolidation_apply_profile_updates=false`. + +Relevant knowledge base settings: + +- `consolidation_enabled`: default `false`; required for `run` +- `consolidation_min_age_days`: default `7` +- `consolidation_max_candidates`: default `20` +- `consolidation_apply_profile_updates`: default `false` + +## Memory Candidate Extraction + +Candidate extraction is disabled by default because automatic memory writes can pollute both L1 profiles and L2 episodic recall, especially in group chats. Enable it only when you want a review queue for possible memory writes: + +- `candidate_extraction_enabled`: default `false` +- `candidate_auto_apply`: default `false` +- `candidate_max_per_turn`: default `3` + +When enabled, the plugin listens to the existing `NormalMessageResponded` event and stores conservative memory candidates for the current scope. Candidates do not modify L1 or L2 unless accepted. Use `!memory candidates [page]` to list pending candidates, `!memory candidates --all-statuses` to inspect accepted and rejected candidates, `!memory candidate accept ` to apply one candidate through the normal profile or episode write path, and `!memory candidate reject ` to keep a rejected candidate inspectable without writing memory. + +Keep `candidate_auto_apply=false` for normal deployments. If `candidate_auto_apply=true`, extracted candidates are accepted immediately and audit entries are written, but this increases the risk of low-value or ambiguous facts entering long-term memory. + +## Retrieval Strategy + +The memory KB supports `retrieval_strategy` values `auto`, `vector`, and `hybrid`. `auto` tries hybrid search with `query_text` and falls back to vector search if the backend does not support hybrid mode. `vector` is the compatibility mode. `exact_match_boost` boosts exact matches on episode IDs, sender identity, tags, and content snippets; searching by an exact episode ID can return that episode without relying on embedding similarity. + +## Context Sharing for Other Plugins + +LongTermMemory writes a structured context summary to the query variable `_ltm_context` during every `PromptPreProcessing` event. Other plugins can read this variable to make programmatic decisions based on user memory, without importing or referencing LongTermMemory in any way. + +### Variable Key + +`_ltm_context` + +### Schema + +```python +{ + "speaker": { + "id": "user_123", # sender_id, may be empty string + "name": "Alice", # sender_name, may be empty string + }, + "session_profile": { # always present, fields may be empty + "name": "", + "traits": ["creative", "analytical"], + "preferences": ["prefers detailed explanations"], + "notes": "", + "updated_at": "2025-03-16T12:00:00Z", + }, + "speaker_profile": { # null when sender_id is unavailable + "name": "Alice", + "traits": ["extroverted"], + "preferences": ["likes humor"], + "notes": "", + "updated_at": "2025-03-16T12:00:00Z", + }, + "episodes": [ # auto-recalled L2 episodic memories, may be empty + {"content": "User mentioned a trip to Beijing last week"}, + ], +} +``` + +### Usage Example + +```python +from langbot_plugin.api.definition.components.common.event_listener import EventListener +from langbot_plugin.api.entities import events, context +from langbot_plugin.api.entities.builtin.provider.message import Message + + +class PersonalityCustomizer(EventListener): + def __init__(self): + super().__init__() + + @self.handler(events.PromptPreProcessing) + async def on_prompt(event_ctx: context.EventContext): + ltm = await event_ctx.get_query_var("_ltm_context") + if not ltm: + # LongTermMemory not installed or inactive — use defaults + return + + profile = ltm.get("speaker_profile") or ltm.get("session_profile") or {} + traits = profile.get("traits", []) + + if "喜欢幽默" in traits: + style = "Use a humorous and playful tone." + elif "偏好简洁" in traits: + style = "Be concise and direct." + else: + return + + event_ctx.event.default_prompt.append( + Message(role="system", content=style) + ) +``` + +### Design Notes + +- If LongTermMemory is not installed, `_ltm_context` does not exist. Consuming plugins should treat `None` as normal and fall back to default behavior. +- If LongTermMemory is active but no profile data has been stored yet, the variable exists with empty fields. This lets consuming plugins distinguish "no memory plugin" from "memory plugin active, no data yet". +- Both sides depend only on the variable key and schema convention, not on each other's code. If LongTermMemory is replaced by another memory plugin that writes the same key with the same schema, consuming plugins continue to work. +- LongTermMemory must run before consuming plugins in the event dispatch order. In practice this depends on plugin installation order. + +## Import / Export + +- **Export (L1 profiles):** Use `!memory export` to export the current scope's session and speaker profiles as JSON. It does not export data from other sessions or scopes. +- **Export (L2 episodic memory):** Use `!memory export l2` to export all L2 episodes for the current `user_key` scope. Add `--status ` or `--include-archived` / `--include-superseded` to narrow the exported lifecycle states. +- **Import (L2 episodic memory):** Use `!memory import l2 ` with either a JSON list of episodes or an object containing an `episodes` list. Imported records are always written into the current scope's `user_key`; any `user_key` in the JSON is ignored and original episode IDs are preserved only as import metadata so another scope cannot be overwritten. +- **Bulk delete (L2 episodic memory):** Use `!memory delete --speaker `, `!memory delete --tag `, `!memory delete --before `, or `!memory delete --status `. Bulk deletion first enumerates the current `user_key` scope, deletes only matching scoped records, reports the affected count, and writes audit entries. +- **L2 episodic memory can also be browsed** via `!memory list [page]`; individual episodes can be deleted via `!memory forget `. + +## Key Technical Q&A + +### Q1. Why split memory into L1 and L2 instead of storing everything in the vector database? + +Because the access patterns are different: + +- L1 contains stable facts and should be injected consistently +- L2 contains event-like memory and should be retrieved on demand + +Putting both into the vector store would make stable profile recall less reliable and make memory updates semantically messy. + +### Q2. Why is L2 retrieved instead of fully injected every turn? + +Because L2 grows over time. Full injection would quickly cause: + +- prompt bloat +- too much irrelevant noise +- old memory crowding out the actually relevant context + +The current strategy is to retrieve a small relevant subset automatically, then let the agent use `recall_memory` if it needs more. + +### Q3. Does L2 memory decay over time? + +Yes. + +L2 ranking does not depend only on vector similarity. It also applies time decay so that newer memories tend to rank higher than older ones. + +The current implementation uses a half-life style approach: + +- when a memory reaches `half_life_days`, its time weight decays to roughly 50% +- newer memory is favored in ranking +- older memory is not deleted automatically; it just loses ranking advantage + +This is meant to prioritize recent context, not to hard-delete the past. + +### Q4. Do old memories eventually disappear completely? + +Not automatically. + +Time decay affects ranking, not hard deletion. Old memories can still be recalled if they remain relevant enough. + +### Q5. How should I choose between `session` and `bot` isolation? + +In practice: + +- choose `session` + - when each group chat / private chat should keep independent memory + - when you want lower risk of cross-session leakage +- choose `bot` + - when the bot should share long-term experience across sessions + - when broader recall is more important than stricter separation + +If you are unsure, start with `session`. + +### Q6. Why does `!memory export` only export the current scope? + +That is a deliberate safety boundary. + +Allowing export of every L1 profile in the plugin instance would make cross-session data leakage much easier. Restricting export to the current scope follows a minimum-exposure principle. + +### Q7. What happens if the runtime does not expose `_knowledge_base_uuids` in query variables? + +Automatic memory injection still works, but the plugin cannot remove its memory KB from naive RAG pre-processing. + +That can lead to duplicate memory recall: + +- one copy injected by LongTermMemory itself +- another copy recalled again by the runner's generic KB flow + +So this is not a full failure, but it can waste context and make the prompt noisier. + +### Q8. How are L2 exports and imports scoped? + +`!memory export l2` exports only the current `user_key` scope. `!memory import l2 ` also writes only into the current `user_key` scope, regardless of any `user_key` fields included in the JSON. Imported records receive new episode IDs; the original IDs are kept as import metadata for traceability. + +### Q9. Will LongTermMemory and AgenticRAG duplicate recall when both are enabled? + +No, that duplication is exactly what the current design avoids: + +- LongTermMemory removes its own naive RAG pre-processing +- automatic L2 recall is handled by LongTermMemory +- deeper ad hoc retrieval can still go through AgenticRAG + +## Components + +- KnowledgeEngine: [memory_engine.py](components/knowledge_engine/memory_engine.py) +- EventListener: [memory_injector.py](components/event_listener/memory_injector.py) +- Tools: [remember.py](components/tools/remember.py), [recall_memory.py](components/tools/recall_memory.py), [update_profile.py](components/tools/update_profile.py), [forget.py](components/tools/forget.py) +- Command: [memory.py](components/commands/memory.py) +- Page: [memory_console.py](components/pages/memory_console/memory_console.py), [index.html](components/pages/memory_console/index.html) + +## Current Gaps + +The README now covers the core design, isolation rules, export boundaries, and major components. + +Still worth adding later: + +- synchronized updates for localized docs +- concrete JSON import examples +- best-practice examples for `remember`, `recall_memory`, and `update_profile` + +## Memory Console + +In addition to the `!memory` command surface, the plugin ships a web **Memory Console** page (registered under the plugin's Page component) for visual inspection and maintenance. It talks to the plugin through scoped page endpoints and never escapes the selected memory space. + +The console is organized into a scope sidebar plus tabbed panels: + +- **Memory Space sidebar** — pick a known scope, or fill in `bot_uuid` / `session_name` / `isolation` and click **Derive** to compute the matching `scope_key` and `user_key`. An **Advanced / Raw** area exposes the underlying keys for power users. +- **Profiles** — view the session profile and the current speaker profile for the selected scope. +- **Episodes** — list (paginated) or semantic-search L2 episodes for the current `user_key`, filtered by lifecycle status; archive, restore, or delete individual episodes inline. Every mutating action writes a scoped audit entry, exactly like the equivalent `!memory` command. +- **Injection** — load the **last memory-injection snapshot** for the scope: whether anything was injected on the latest turn, how many blocks and characters, which speaker, the session/speaker profiles that were used, and the L2 episodes that were auto-recalled. This answers "what did the bot actually remember on the last turn?" without scraping logs. +- **Audit** — browse (paginated) and export the scoped audit log. +- **Export** — export L1 profiles and L2 episodes for the current scope as JSON. +- **Diagnostics** — **Run Health Check** executes the same metadata-isolation probe as `!memory health` directly from the UI (KB config, embedding model, and `user_key` filter isolation on search / list / delete), rendered as red/amber/green status cards. Use this before trusting scoped recall, especially on backends listed as unsupported above. Note: the console cannot verify that the KB is attached to a specific pipeline — run `!memory health` inside a pipeline to confirm that part. **Clear Fence** acknowledges reconciliation for the selected memory space / knowledge base after a Host write whose outcome was unknown; see [Write serialization and fences](#write-serialization-and-fences). + +The console is i18n-aware (`en_US`, `zh_Hans`) and follows the host LangBot light/dark theme. + +## Write serialization and fences + +L1 records are grouped by `scope_key` (session/subject scope) and L2 episodes by collection id, so writes are serialized per **installation binding + memory scope**: an in-flight ambiguity for one memory space never blocks the other spaces that share the installation. The single installation-wide `kb_configs` map is serialized on the installation scope, because every KB shares that one record. + +A Host write that was **dispatched with an unknown outcome** (timeout, lost connection, cancelled call) fences only that memory scope, and the marker is persisted in installation storage, so a restarted worker still refuses writes to it — a retry could double-apply. The fence does not block reads (recall, listing, export, health). Deterministic failures never fence: a validation error raised before the call, an error detected after the Host answered authoritatively, and ordinary cancellation before a write is dispatched all leave the scope writable. + +To get a fenced space writable again: + +- **Clear Fence** in the Memory Console's **Diagnostics** tab — clears the fence for the selected memory space and knowledge base. Use it after checking the affected records (the console's Profiles / Episodes / Audit tabs, and `!memory list` / `!memory audit`). +- Unregistering a memory KB (`remove_kb_config`) clears that collection's fence, because the fenced object is gone and its pending ambiguity became moot. +- For an installation-wide fence (an unknown outcome on the shared `kb_configs` map) the console clears it only when the request explicitly asks for the installation scope, because it blocks every memory space. + +## Logging + +The plugin now emits logs at key memory lifecycle points so you can observe how long-term memory is being used during runtime. + +You will see logs for: + +- plugin initialization and resolved memory context +- `remember`, `recall_memory`, and `update_profile` tool calls +- profile injection before model invocation +- automatic L2 memory retrieval in the KnowledgeEngine +- episodic memory vector writes, searches, import batches, and deletes + +Beyond logs, the most recent profile injection and L2 recall for each scope are also persisted as a structured snapshot and surfaced in the Memory Console's **Injection** tab, so you can inspect runtime behavior visually instead of only through log scraping. + +Typical log messages look like: + +```text +[LongTermMemory] remember called: query_id=123 params_keys=['content', 'importance', 'tags'] +[LongTermMemory] memory injection ready: query_id=123 kb_id=kb-1 scope_key=bot:xxx:group_123 sender_id=u1 block_count=2 prompt_chars=280 +[LongTermMemory] engine retrieve called: collection_id=kb-1 top_k=5 session_name=group_123 sender_id=u1 bot_uuid=bot-1 query='user asked about travel plan' +[LongTermMemory] search_episodes completed: collection_id=kb-1 result_count=3 filters={'user_key': 'bot:bot-1:group_123'} +``` + +## Contributing + +We welcome contributions!

Un despliegue típico de LangBot se parece más a: + +- un bot sirviendo múltiples chats grupales y chats privados +- una instancia del plugin manejando múltiples sesiones y múltiples hablantes +- memoria que incluye contexto grupal compartido, perfil del hablante actual y hechos episódicos a nivel de sesión +- límites de aislamiento explícitos entre sesiones, bots y hablantes + +Debido a eso, no adoptamos un diseño de "un solo archivo de texto como fuente de verdad". Elegimos una arquitectura en capas que coincide mejor con el modelo de tiempo de ejecución multisesión de LangBot. + +### Para qué está optimizada la memoria tipo OpenClaw + +Abstactamente, ese diseño está optimizado para: + +- **asistentes personales de un solo usuario** +- **texto legible por humanos como la forma principal de memoria a largo plazo** +- **transparencia, editabilidad y continuidad narrativa** +- **la suposición de que el tamaño de la memoria se mantiene manejable y el usuario está dispuesto a curarla directamente** + +Es un ajuste muy razonable para compañeros de IA personales, copilotos de investigación y flujos de trabajo de asistentes privados. + +### Por qué LangBot no simplemente copia ese modelo + +LongTermMemory está diseñado en torno a diferentes restricciones operativas: múltiples sesiones, múltiples hablantes, aislamiento explícito, inyección controlada y recuperación episódica recuperable. + +Si convirtiéramos la memoria a largo plazo en un archivo narrativo como `MEMORY.md`, aparecerían rápidamente varios problemas: + +- **El aislamiento sería difícil** + - ¿cómo deberían coexistir de forma segura las memorias del grupo A, el grupo B y el chat privado C? + - ¿cómo se separa limpiamente el perfil estable de un solo hablante de un registro narrativo compartido? +- **La granularidad de la inyección sería inestable** + - los prompts del sistema necesitan un estado de perfil estable, no un diario cronológico completo + - la recuperación automática necesita los fragmentos de memoria más relevantes para la consulta actual, no toda la historia +- **Los límites multiusuario son de primera clase en LangBot** + - en un asistente personal, "el usuario" suele ser una persona + - en LangBot, el hablante actual, la sesión actual y el bot actual importan +- **La inyección automática y la recuperación activa son necesidades diferentes** + - los datos de perfil estables deben inyectarse de forma consistente + - la memoria episódica debe recuperarse selectivamente + - forzar ambos en una sola forma de memoria de solo texto se vuelve incómodo + +### El compromiso que hicimos + +Así que el diseño de LongTermMemory es esencialmente este compromiso: + +- **Lo que tomamos prestado de esa filosofía** + - la memoria no debe tratarse solo como un almacén de vectores de caja negra + - el perfil estable, la memoria temporal y el ajuste de comportamiento a largo plazo importan + - no todo debe volcarse en el contexto en cada turno + +- **Donde nos diferenciamos deliberadamente** + - no utilizamos un diario de texto narrativo como la única fuente de verdad de la memoria + - dividimos explícitamente el perfil estable y la memoria episódica + - priorizamos el aislamiento entre sesiones, hablantes y bots + - permitimos que la memoria L2 se conecte naturalmente al sistema de KB / recuperación de LangBot en lugar de depender solo de la lectura de texto completo + +En resumen: + +- OpenClaw responde principalmente a: "¿Cómo debería un asistente personal mantener una memoria a largo plazo legible, editable y reflexiva?" +- LongTermMemory responde principalmente a: "¿Cómo debería un bot que trabaja en grupos y chats privados mantener un estado de perfil estable y una memoria de experiencia recuperable bajo reglas de aislamiento explícitas?" + +Ninguna dirección es universalmente "mejor". Optimizan para diferentes productos y diferentes modos de falla. + +## Diseño + +Este plugin permanece intencionalmente cerca de los puntos de extensión existentes de LangBot en lugar de requerir parches personalizados en el núcleo. + +- El perfil L1 se almacena en el almacenamiento del plugin como JSON +- La memoria episódica L2 se almacena en la base de datos de vectores +- La recuperación de memoria se habilita por flujo de trabajo adjuntando el KnowledgeEngine de este plugin +- El plugin asume actualmente una única KB de memoria por instancia de plugin e aísla la memoria mediante metadatos + +La implementación actual se basa en las APIs existentes de LangBot y el SDK. Si LangBot agrega más adelante APIs más explícitas orientadas a la memoria, APIs de identidad de sesión o APIs de registro de KB, el plugin podría simplificarse, pero la arquitectura actual seguiría siendo válida. + +### Compatibilidad con el motor de base de datos de vectores + +La memoria episódica L2 depende de campos de metadatos arbitrarios (`user_key`, `episode_id`, `tags`, `importance`, etc.) para el aislamiento y el filtrado. No todos los motores de base de datos de vectores de LangBot admiten metadatos arbitrarios: + +| Motor | Metadatos arbitrarios | Soporte de LongTermMemory | +|---------|-------------------|----------------------| +| **Chroma** (predeterminado) | Sí | Soporte completo | +| **Qdrant** | Sí | Soporte completo | +| **SeekDB** | Sí | Soporte completo | +| **Milvus** | No (esquema fijo: `text`, `file_id`, `chunk_uuid`) | No soportado | +| **pgvector** | No (esquema fijo: `text`, `file_id`, `chunk_uuid`) | No soportado | + +Milvus y pgvector utilizan un esquema de columnas fijo y descartan silenciosamente los campos de metadatos que no reconocen. Esto significa que el aislamiento basado en metadatos (filtrado por `user_key`) y los comandos de memoria episódica (`!memory list`, `!memory forget`, `!memory search`) no funcionarán correctamente en estos motores; los filtros se ignorarán y las consultas pueden devolver resultados fuera de alcance. + +Si necesita usar LongTermMemory, utilice Chroma, Qdrant o SeekDB como su motor de base de datos de vectores. + +## Cómo funciona + +Un flujo de memoria a largo plazo de extremo a extremo tiene cuatro partes principales: + +### 1. Escrituras de perfil L1 + +- El agente utiliza `update_profile` para escribir hechos estables +- Los datos se almacenan en el almacenamiento del plugin como JSON estructurado +- Los perfiles se almacenan en el ámbito de `session` o `speaker` + +### 2. Escrituras episódicas L2 + +- El agente utiliza `remember` para escribir memorias tipo evento +- Cada memoria lleva metadatos como marca de tiempo, importancia, etiquetas y ámbito +- Esas memorias se vectorizan y almacenan en la base de datos de vectores a través del KnowledgeEngine del plugin + +### 3. Inyección automática previa a la respuesta + +- Durante `PromptPreProcessing`, el EventListener resuelve la identidad de la sesión actual +- Para L1: + - carga el perfil de sesión compartido + - carga el perfil del hablante actual + - inyecta ambos, junto con la identidad del hablante actual, en `default_prompt` +- Para L2: + - ejecuta una recuperación episódica utilizando el mensaje del usuario actual + - las memorias recuperadas se inyectan como bloques de contexto factual + +Así que tanto L1 como L2 entran en el contexto del modelo antes de la generación de la respuesta, pero en formas diferentes: L1 como memoria de prompt del sistema, L2 como contexto recuperado. + +### 4. Búsqueda activa y depuración + +- Si la inyección automática es insuficiente, el agente puede llamar a `recall_memory` +- Para inspección y depuración, puede usar `!memory`, `!memory profile`, `!memory search`, `!memory list` y `!memory forget` +- `!memory export` exporta solo los perfiles L1 del ámbito actual para respaldo o migración + +## Relación con AgenticRAG + +Cuando AgenticRAG está habilitado junto con LongTermMemory: + +- LongTermMemory elimina su propia KB de memoria del preprocesamiento RAG ingenuo +- la recuperación automática L2 sigue siendo manejada por el propio LongTermMemory +- la misma KB de memoria se puede consultar explícitamente a través de la herramienta `query_knowledge` de AgenticRAG + +Esto evita la recuperación duplicada mientras se conservan ambas rutas: + +- recuperación automática de memoria +- recuperación más profunda iniciada por el agente cuando sea necesario + +## Por qué no hay un filtro de metadatos del lado del agente + +El tiempo de ejecución subyacente puede admitir el filtrado de metadatos, pero este plugin no expone filtros de metadatos sin procesar arbitrarios al flujo del agente hoy en día. + +Razones: + +- Los diferentes motores de conocimiento y motores vectoriales no comparten un esquema de metadatos unificado +- Los nombres de los campos de filtro, los formatos de valor y los operadores admitidos pueden diferir +- El agente actualmente no tiene una fuente de esquema estable para construir filtros confiables + +Si LangBot proporciona más adelante una forma unificada de describir los campos de metadatos filtrables por base de conocimiento, se puede agregar el filtrado de metadatos del lado del agente. + +Este plugin proporciona una interfaz de herramienta de recuperación controlada para su propio esquema de memoria estable. Esa herramienta admite filtros seleccionados como el hablante y el rango de tiempo, sin exponer una sintaxis de filtro específica del motor al modelo. + +## Modelo de aislamiento + +Se admiten dos modos de aislamiento: + +- `session`: cada chat grupal o chat privado tiene memoria independiente +- `bot`: todas las sesiones bajo el mismo bot comparten la memoria + +En el modelo de despliegue actual, esto es generalmente suficiente porque las instancias del plugin suelen estar vinculadas a un entorno de bot/tiempo de ejecución de LangBot específico. + +## Reglas de aislamiento en detalle + +Hay dos conceptos de ámbito relacionados pero ligeramente diferentes en este plugin: + +- **session_name**: la identidad de la conversación pasada a través de la ruta de consulta / recuperación actual, formateada como `{launcher_type}_{launcher_id}` +- **session_key**: la clave de almacenamiento L1 interna del plugin. Cuando `bot_uuid` está disponible, se convierte en `{bot_uuid}:{launcher_type}_{launcher_id}`; de lo contrario, vuelve a `{launcher_type}_{launcher_id}` +- **scope_key / user_key**: la clave real utilizada para el almacenamiento de perfiles o el aislamiento de recuperación L2 + +### Cómo se aíslan los perfiles L1 + +Los perfiles L1 siempre se almacenan dentro del ámbito de la conversación actual: + +- `session profile` + - perfil compartido para la conversación actual + - útil para contexto estable a nivel de grupo o conversación +- `speaker profile` + - hechos estables sobre el hablante actual + - útil para preferencias específicas de la persona, identidad y notas + +Debido a eso, `!memory export` exporta solo los perfiles que pertenecen a la `session_key` actual, no todos los perfiles en toda la instancia del plugin. + +### Cómo se aísla la memoria episódica L2 + +Las memorias L2 se escriben en el almacén de vectores con metadatos de aislamiento, luego se filtran en el momento de la recuperación: + +- `session` + - las memorias del grupo A no se recuperan en el grupo B + - las memorias de un chat privado no se recuperan en otro +- `bot` + - todas las sesiones bajo el mismo bot comparten un espacio de memoria episódica + - útil cuando se desea compartir experiencias a largo plazo entre sesiones + +Cuando `sender_id` está disponible, el plugin también puede preferir memorias relacionadas con el hablante antes de ampliar al ámbito más general. + +### Por qué el aislamiento L1 y L2 no son exactamente iguales + +Eso es intencional: + +- L1 se comporta como un estado de perfil estable, por lo que el almacenamiento preciso de sesión / hablante tiene sentido +- L2 se comporta como una base de experiencias recuperable, por lo que el filtrado basado en metadatos es el modelo más escalable +- esto mantiene L1 preciso y L2 flexible + +## Cómo usar + +1. Instale y habilite el plugin. +2. Cree una base de conocimiento de memoria con el KnowledgeEngine de este plugin. +3. Configure: + - `embedding_model_uuid` + - `isolation` + - opcional `recency_half_life_days` + - opcional `auto_recall_top_k` +4. Deje que el agente use: + - `remember` para eventos, planes y hechos episódicos + - `recall_memory` para la búsqueda activa de memoria cuando la recuperación automática es insuficiente + - `update_profile` para preferencias estables y datos de perfil + - `forget` para eliminar una memoria episódica específica por ID +5. Use `!memory`, `!memory profile`, `!memory search `, `!memory list [page]`, `!memory forget ` y `!memory export` para inspeccionar el comportamiento. + +## Compartir contexto para otros plugins + +LongTermMemory escribe un resumen de contexto estructurado en la variable de consulta `_ltm_context` durante cada evento `PromptPreProcessing`. Otros plugins pueden leer esta variable para tomar decisiones programáticas basadas en la memoria del usuario, sin importar ni referenciar LongTermMemory de ninguna manera. + +### Clave de variable + +`_ltm_context` + +### Esquema + +```python +{ + "speaker": { + "id": "user_123", # sender_id, puede ser una cadena vacía + "name": "Alice", # sender_name, puede ser una cadena vacía + }, + "session_profile": { # siempre presente, los campos pueden estar vacíos + "name": "", + "traits": ["creative", "analytical"], + "preferences": ["prefers detailed explanations"], + "notes": "", + "updated_at": "2025-03-16T12:00:00Z", + }, + "speaker_profile": { # null cuando sender_id no está disponible + "name": "Alice", + "traits": ["extroverted"], + "preferences": ["likes humor"], + "notes": "", + "updated_at": "2025-03-16T12:00:00Z", + }, + "episodes": [ # memorias episódicas L2 recuperadas automáticamente, pueden estar vacías + {"content": "User mentioned a trip to Beijing last week"}, + ], +} +``` + +### Ejemplo de uso + +```python +from langbot_plugin.api.definition.components.common.event_listener import EventListener +from langbot_plugin.api.entities import events, context +from langbot_plugin.api.entities.builtin.provider.message import Message + + +class PersonalityCustomizer(EventListener): + def __init__(self): + super().__init__() + + @self.handler(events.PromptPreProcessing) + async def on_prompt(event_ctx: context.EventContext): + ltm = await event_ctx.get_query_var("_ltm_context") + if not ltm: + # LongTermMemory no instalado o inactivo — usar valores predeterminados + return + + profile = ltm.get("speaker_profile") or ltm.get("session_profile") or {} + traits = profile.get("traits", []) + + if "likes humor" in traits: + style = "Use a humorous and playful tone." + elif "prefers concise" in traits: + style = "Be concise and direct." + else: + return + + event_ctx.event.default_prompt.append( + Message(role="system", content=style) + ) +``` + +### Notas de diseño + +- Si LongTermMemory no está instalado, `_ltm_context` no existe. Los plugins consumidores deben tratar `None` como normal y volver al comportamiento predeterminado. +- Si LongTermMemory está activo pero aún no se han almacenado datos de perfil, la variable existe con campos vacíos. Esto permite a los plugins consumidores distinguir entre "sin plugin de memoria" y "plugin de memoria activo, sin datos aún". +- Ambas partes dependen solo de la clave de variable y la convención de esquema, no del código del otro. Si LongTermMemory es reemplazado por otro plugin de memoria que escribe la misma clave con el mismo esquema, los plugins consumidores continúan funcionando. +- LongTermMemory debe ejecutarse antes que los plugins consumidores en el orden de despacho de eventos. En la práctica, esto depende del orden de instalación del plugin. + +## Importación / Exportación + +- **Exportación (perfiles L1):** Use `!memory export` para exportar los perfiles de sesión y hablante del ámbito actual como JSON. No exporta datos de otras sesiones o ámbitos. +- **Importación (memoria episódica L2):** Cargue un archivo JSON a través de la interfaz de usuario de la base de conocimiento de LangBot para importar memorias episódicas de forma masiva. +- **La memoria episódica L2 se puede examinar** a través de `!memory list [page]` y los episodios individuales se pueden eliminar a través de `!memory forget `. La exportación masiva completa aún no está implementada. + +## Preguntas técnicas clave + +### Q1. ¿Por qué dividir la memoria en L1 y L2 en lugar de almacenar todo en la base de datos de vectores? + +Porque los patrones de acceso son diferentes: + +- L1 contiene hechos estables y debe inyectarse de forma consistente +- L2 contiene memoria tipo evento y debe recuperarse bajo demanda + +Poner ambos en el almacén de vectores haría que la recuperación del perfil estable fuera menos confiable y haría que las actualizaciones de memoria fueran semánticamente desordenadas. + +### Q2. ¿Por qué se recupera L2 en lugar de inyectarse completamente en cada turno? + +Porque L2 crece con el tiempo. La inyección completa causaría rápidamente: + +- hinchazón del prompt +- demasiado ruido irrelevante +- la memoria antigua desplazando al contexto realmente relevante + +La estrategia actual es recuperar automáticamente un pequeño subconjunto relevante, luego dejar que el agente use `recall_memory` si necesita más. + +### Q3. ¿La memoria L2 decae con el tiempo? + +Sí. + +La clasificación L2 no depende solo de la similitud vectorial. También aplica un decaimiento temporal para que las memorias más nuevas tiendan a clasificarse más alto que las más antiguas. + +La implementación actual utiliza un enfoque de estilo vida media: + +- cuando una memoria alcanza `half_life_days`, su peso temporal decae a aproximadamente el 50% +- se favorece la memoria más nueva en la clasificación +- la memoria más antigua no se elimina automáticamente; simplemente pierde ventaja en la clasificación + +Esto tiene como objetivo priorizar el contexto reciente, no eliminar de forma drástica el pasado. + +### Q4. ¿Las memorias antiguas acaban desapareciendo por completo? + +No automáticamente. + +El decaimiento temporal afecta a la clasificación, no a la eliminación drástica. Las memorias antiguas aún pueden recuperarse si siguen siendo lo suficientemente relevantes. + +### Q5. ¿Cómo debo elegir entre el aislamiento de `session` y `bot`? + +En la práctica: + +- elija `session` + - cuando cada chat grupal / chat privado deba mantener una memoria independiente + - cuando desee un menor riesgo de fuga entre sesiones +- elija `bot` + - cuando el bot deba compartir la experiencia a largo plazo entre sesiones + - cuando la recuperación más amplia sea más importante que una separación más estricta + +Si no está seguro, comience con `session`. + +### Q6. ¿Por qué `!memory export` solo exporta el ámbito actual? + +Ese es un límite de seguridad deliberado. + +Permitir la exportación de cada perfil L1 en la instancia del plugin facilitaría mucho la fuga de datos entre sesiones. Restringir la exportación al ámbito actual sigue un principio de exposición mínima. + +### Q7. ¿Qué sucede si el tiempo de ejecución no expone `_knowledge_base_uuids` en las variables de consulta? + +La inyección automática de memoria sigue funcionando, pero el plugin no puede eliminar su propia KB de memoria del preprocesamiento RAG ingenuo. + +Eso puede llevar a una recuperación de memoria duplicada: + +- una copia inyectada por el propio LongTermMemory +- otra copia recuperada de nuevo por el flujo genérico de KB del ejecutor + +Así que esto no es un fallo total, pero puede desperdiciar contexto y hacer que el prompt sea más ruidoso. + +### Q8. ¿Por qué no se admite aún la exportación L2? + +El SDK ahora proporciona una API `vector_list` para la enumeración paginada del contenido del almacén de vectores. Las memorias episódicas L2 se pueden examinar a través de `!memory list [page]` y eliminarse individualmente a través de `!memory forget ` o la herramienta `forget`. + +La exportación masiva completa aún no está implementada, pero las piezas fundamentales están en su lugar. + +### Q9. ¿LongTermMemory y AgenticRAG duplicarán la recuperación cuando ambos estén habilitados? + +No, esa duplicación es exactamente lo que evita el diseño actual: + +- LongTermMemory elimina su propio preprocesamiento RAG ingenuo +- la recuperación automática L2 es manejada por LongTermMemory +- la recuperación ad hoc más profunda aún puede realizarse a través de AgenticRAG + +## Consola de Memoria + +Además del comando `!memory`, el plugin incluye una página web **Consola de Memoria** (registrada como el componente Page del plugin) para inspección visual y mantenimiento. Se comunica con el plugin a través de endpoints de página acotados al alcance y nunca sale del espacio de memoria seleccionado. + +La consola se organiza en una barra lateral de espacio más paneles con pestañas: + +- **Barra lateral de espacio de memoria** —— elige un alcance conocido, o completa `bot_uuid` / `session_name` / `isolation` y haz clic en **Derive** para calcular el `scope_key` y el `user_key` correspondientes. Un área **Advanced / Raw** expone las claves internas. +- **Perfiles** —— muestra el perfil de sesión y el perfil del hablante actual del alcance seleccionado. +- **Episodios** —— lista (paginada) o busca semánticamente los episodios L2 del `user_key` actual, filtrados por estado del ciclo de vida; archiva, restaura o elimina episodios en línea.

ความจำที่ดึงมาจะถูกฉีดเป็นบล็อกบริบทข้อเท็จจริง + +ดังนั้นทั้ง L1 และ L2 จะเข้าสู่บริบทของโมเดลก่อนการสร้างคำตอบ แต่ในรูปแบบที่แตกต่างกัน: L1 เป็นความจำใน prompt ของระบบ, L2 เป็นบริบทที่ดึงมา + +### 4. การค้นหาเชิงรุกและการดีบัก + +- หากการฉีดอัตโนมัติไม่เพียงพอ เอเจนต์สามารถเรียกใช้ `recall_memory` +- สำหรับการตรวจสอบและการดีบัก คุณสามารถใช้ `!memory`, `!memory profile`, `!memory search`,

Chúng tối ưu hóa cho các sản phẩm khác nhau và các chế độ lỗi khác nhau. + +## Thiết kế + +Plugin này cố tình bám sát các điểm mở rộng hiện có của LangBot thay vì yêu cầu các bản vá lõi tùy chỉnh. + +- Cấu hình L1 được lưu trữ trong bộ nhớ plugin dưới dạng JSON +- Bộ nhớ tình tiết L2 được lưu trữ trong cơ sở dữ liệu vector +- Truy xuất bộ nhớ được bật cho mỗi pipeline bằng cách đính kèm KnowledgeEngine của plugin này +- Plugin hiện giả định một KB bộ nhớ duy nhất cho mỗi thực thể plugin và cô lập bộ nhớ bằng siêu dữ liệu (metadata) + +Bản thực hiện hiện tại được xây dựng xung quanh các API hiện có của LangBot và SDK. Nếu sau này LangBot thêm nhiều API hướng tới bộ nhớ rõ ràng hơn, API danh tính phiên hoặc API đăng ký KB, plugin có thể được đơn giản hóa, nhưng kiến trúc hiện tại vẫn sẽ có giá trị. + +### Khả năng tương thích của Backend cơ sở dữ liệu Vector + +Bộ nhớ tình tiết L2 dựa trên các trường siêu dữ liệu tùy ý (`user_key`, `episode_id`, `tags`, `importance`, v.v.) để cô lập và lọc. Không phải tất cả các backend cơ sở dữ liệu vector của LangBot đều hỗ trợ siêu dữ liệu tùy ý: + +| Backend | Siêu dữ liệu tùy ý | Hỗ trợ LongTermMemory | +|---------|-------------------|----------------------| +| **Chroma** (mặc định) | Có | Hỗ trợ đầy đủ | +| **Qdrant** | Có | Hỗ trợ đầy đủ | +| **SeekDB** | Có | Hỗ trợ đầy đủ | +| **Milvus** | Không (schema cố định: `text`, `file_id`, `chunk_uuid`) | Không hỗ trợ | +| **pgvector** | Không (schema cố định: `text`, `file_id`, `chunk_uuid`) | Không hỗ trợ | + +Milvus và pgvector sử dụng một schema cột cố định và âm thầm loại bỏ các trường siêu dữ liệu mà chúng không nhận ra. Điều này có nghĩa là việc cô lập dựa trên siêu dữ liệu (lọc `user_key`) và các lệnh bộ nhớ tình tiết (`!memory list`, `!memory forget`, `!memory search`) sẽ không hoạt động chính xác trên các backend này — các bộ lọc sẽ bị bỏ qua và các truy vấn có thể trả về kết quả không có phạm vi. + +Nếu bạn cần sử dụng LongTermMemory, hãy sử dụng Chroma, Qdrant hoặc SeekDB làm backend cơ sở dữ liệu vector của bạn. + +## Cách thức hoạt động + +Một luồng bộ nhớ dài hạn từ đầu đến cuối có bốn phần chính: + +### 1. Ghi cấu hình L1 + +- Agent sử dụng `update_profile` để ghi lại các sự thật ổn định +- Dữ liệu được lưu trữ trong bộ nhớ plugin dưới dạng JSON có cấu trúc +- Cấu hình được lưu trữ ở phạm vi `session` (phiên) hoặc `speaker` (người nói) + +### 2. Ghi tình tiết L2 + +- Agent sử dụng `remember` để ghi lại bộ nhớ dạng sự kiện +- Mỗi bộ nhớ mang siêu dữ liệu như dấu thời gian, tầm quan trọng, thẻ và phạm vi +- Những bộ nhớ đó được nhúng và lưu trữ trong cơ sở dữ liệu vector thông qua KnowledgeEngine của plugin + +### 3. Tự động chèn trước khi phản hồi + +- Trong quá trình `PromptPreProcessing`, EventListener sẽ phân giải danh tính phiên hiện tại +- Đối với L1: + - nó tải cấu hình phiên dùng chung + - nó tải cấu hình người nói hiện tại + - nó chèn cả hai, cùng với danh tính người nói hiện tại, vào `default_prompt` +- Đối với L2: + - nó chạy một truy xuất tình tiết bằng tin nhắn của người dùng hiện tại + - các bộ nhớ được truy xuất được chèn vào dưới dạng các khối ngữ cảnh thực tế + +Vì vậy cả L1 và L2 đều đi vào ngữ cảnh mô hình trước khi tạo câu trả lời, nhưng dưới các hình thức khác nhau: L1 dưới dạng bộ nhớ prompt hệ thống, L2 dưới dạng ngữ cảnh được truy xuất. + +### 4. Tra cứu chủ động và gỡ lỗi + +- Nếu việc chèn tự động là không đủ, agent có thể gọi `recall_memory` +- Để kiểm tra và gỡ lỗi, bạn có thể sử dụng `!memory`, `!memory profile`, `!memory search`, `!memory list` và `!memory forget` +- `!memory export` chỉ xuất cấu hình L1 của phạm vi hiện tại để sao lưu hoặc di chuyển + +## Quan hệ với AgenticRAG + +Khi AgenticRAG được bật cùng với LongTermMemory: + +- LongTermMemory loại bỏ KB bộ nhớ của chính nó khỏi quá trình tiền xử lý RAG thông thường +- truy xuất L2 tự động vẫn được xử lý bởi chính LongTermMemory +- cùng một KB bộ nhớ vẫn có thể được truy vấn rõ ràng thông qua công cụ `query_knowledge` của AgenticRAG + +Điều này tránh việc truy xuất trùng lặp trong khi vẫn bảo toàn cả hai con đường: + +- truy xuất bộ nhớ tự động +- truy xuất sâu hơn do agent khởi xướng khi cần thiết + +## Tại sao không có bộ lọc siêu dữ liệu phía Agent + +Runtime bên dưới có thể hỗ trợ lọc siêu dữ liệu, nhưng plugin này hiện không để lộ các bộ lọc siêu dữ liệu thô tùy ý cho luồng của agent. + +Lý do: + +- Các công cụ kiến thức và backend vector khác nhau không chia sẻ một schema siêu dữ liệu thống nhất +- Tên trường bộ lọc, định dạng giá trị và các toán tử được hỗ trợ có thể khác nhau +- Agent hiện không có nguồn schema ổn định để xây dựng các bộ lọc đáng tin cậy + +Nếu sau này LangBot cung cấp một cách thống nhất để mô tả các trường siêu dữ liệu có thể lọc trên mỗi cơ sở kiến thức, tính năng lọc siêu dữ liệu phía agent có thể được thêm vào. + +Plugin này cung cấp một giao diện công cụ truy xuất có kiểm soát cho schema bộ nhớ ổn định của riêng nó. Công cụ đó hỗ trợ các bộ lọc được chọn như người nói và phạm vi thời gian, mà không để lộ cú pháp bộ lọc đặc thù của backend cho mô hình. + +## Mô hình cô lập + +Hai chế độ cô lập được hỗ trợ: + +- `session`: mỗi cuộc trò chuyện nhóm hoặc trò chuyện riêng tư có bộ nhớ độc lập +- `bot`: tất cả các phiên dưới cùng một bot dùng chung bộ nhớ + +Trong mô hình triển khai hiện tại, điều này nói chung là đủ vì các thực thể plugin thường được gắn với một môi trường runtime/bot LangBot cụ thể. + +## Chi tiết các quy tắc cô lập + +Có hai khái niệm phạm vi liên quan nhưng hơi khác nhau trong plugin này: + +- **session_name**: danh tính cuộc trò chuyện được truyền qua đường dẫn truy vấn / truy xuất hiện tại, có định dạng là `{launcher_type}_{launcher_id}` +- **session_key**: khóa lưu trữ L1 nội bộ của plugin. Khi có `bot_uuid`, nó trở thành `{bot_uuid}:{launcher_type}_{launcher_id}`; nếu không nó sẽ trở lại thành `{launcher_type}_{launcher_id}` +- **scope_key / user_key**: khóa thực sự được sử dụng để lưu trữ cấu hình hoặc cô lập truy xuất L2 + +### Cách các cấu hình L1 được cô lập + +Các cấu hình L1 luôn được lưu trữ trong phạm vi cuộc trò chuyện hiện tại: + +- `session profile` + - cấu hình dùng chung cho cuộc trò chuyện hiện tại + - hữu ích cho ngữ cảnh ổn định cấp nhóm hoặc cấp cuộc trò chuyện +- `speaker profile` + - các sự thật ổn định về người nói hiện tại + - hữu ích cho các sở thích, danh tính và ghi chú cụ thể của từng người + +Vì lý do đó, `!memory export` chỉ xuất các cấu hình thuộc về `session_key` hiện tại, không phải mọi cấu hình trong toàn bộ thực thể plugin. + +### Cách bộ nhớ tình tiết L2 được cô lập + +Các bộ nhớ L2 được ghi vào kho lưu trữ vector với siêu dữ liệu cô lập, sau đó được lọc tại thời điểm truy xuất: + +- `session` + - bộ nhớ từ nhóm A không được gọi lại trong nhóm B + - bộ nhớ từ một cuộc trò chuyện riêng tư không được gọi lại trong một cuộc trò chuyện khác +- `bot` + - tất cả các phiên dưới cùng một bot dùng chung một không gian bộ nhớ tình tiết + - hữu ích khi bạn muốn chia sẻ trải nghiệm dài hạn giữa các phiên + +Khi có `sender_id`, plugin cũng có thể ưu tiên các bộ nhớ liên quan đến người nói trước khi mở rộng ra phạm vi rộng hơn. + +### Tại sao cô lập L1 và L2 không hoàn toàn giống nhau + +Đó là sự cố ý: + +- L1 hoạt động giống như trạng thái cấu hình ổn định, vì vậy việc lưu trữ chính xác theo phiên / người nói là hợp lý +- L2 hoạt động giống như một cơ sở trải nghiệm có thể truy xuất, vì vậy lọc dựa trên siêu dữ liệu là mô hình có khả năng mở rộng tốt hơn +- điều này giữ cho L1 chính xác và L2 linh hoạt + +## Cách sử dụng + +1.

Các plugin tiêu thụ nên coi `None` là bình thường và quay lại hành vi mặc định. +- Nếu LongTermMemory đang hoạt động nhưng chưa có dữ liệu cấu hình nào được lưu trữ, biến này vẫn tồn tại với các trường trống. Điều này cho phép các plugin tiêu thụ phân biệt giữa "không có plugin bộ nhớ" và "plugin bộ nhớ đang hoạt động, chưa có dữ liệu". +- Cả hai bên chỉ phụ thuộc vào khóa biến và quy ước schema, không phụ thuộc vào mã của nhau. Nếu LongTermMemory được thay thế bằng một plugin bộ nhớ khác ghi vào cùng một khóa với cùng một schema, các plugin tiêu thụ vẫn tiếp tục hoạt động. +- LongTermMemory phải chạy trước các plugin tiêu thụ trong thứ tự điều phối sự kiện. Trong thực tế, điều này phụ thuộc vào thứ tự cài đặt plugin. + +## Nhập / Xuất + +- **Xuất (cấu hình L1):** Sử dụng `!memory export` để xuất cấu hình phiên và người nói của phạm vi hiện tại dưới dạng JSON.

Việc xuất hàng loạt đầy đủ vẫn chưa được thực hiện. + +## Các câu hỏi kỹ thuật chính + +### Q1. Tại sao chia bộ nhớ thành L1 và L2 thay vì lưu trữ mọi thứ trong cơ sở dữ liệu vector? + +Bởi vì các mẫu truy cập là khác nhau: + +- L1 chứa các sự thật ổn định và nên được chèn một cách nhất quán +- L2 chứa bộ nhớ dạng sự kiện và nên được truy xuất theo yêu cầu + +Việc đưa cả hai vào kho lưu trữ vector sẽ làm cho việc gọi lại cấu hình ổn định kém tin cậy hơn và làm cho các cập nhật bộ nhớ trở nên lộn xộn về mặt ngữ nghĩa. + +### Q2. Tại sao L2 được truy xuất thay vì chèn đầy đủ sau mỗi lượt? + +Bởi vì L2 tăng dần theo thời gian. Việc chèn đầy đủ sẽ nhanh chóng gây ra: + +- làm phình prompt +- quá nhiều nhiễu không liên quan +- bộ nhớ cũ lấn át ngữ cảnh thực sự liên quan + +Chiến lược hiện tại là tự động truy xuất một tập hợp con nhỏ liên quan, sau đó để agent sử dụng `recall_memory` nếu nó cần thêm. + +### Q3. Bộ nhớ L2 có bị phai nhạt theo thời gian không? + +Có. + +Xếp hạng L2 không chỉ phụ thuộc vào độ tương tự vector. Nó cũng áp dụng sự suy giảm theo thời gian để các bộ nhớ mới hơn có xu hướng xếp hạng cao hơn các bộ nhớ cũ hơn. + +Bản thực hiện hiện tại sử dụng phương pháp kiểu chu kỳ bán rã (half-life): + +- khi một bộ nhớ đạt đến `half_life_days`, trọng số thời gian của nó giảm xuống còn khoảng 50% +- bộ nhớ mới hơn được ưu tiên trong xếp hạng +- bộ nhớ cũ hơn không bị xóa tự động; nó chỉ mất lợi thế xếp hạng + +Điều này nhằm mục đích ưu tiên ngữ cảnh gần đây, không phải để xóa cứng quá khứ. + +### Q4. Các bộ nhớ cũ cuối cùng có biến mất hoàn toàn không? + +Không tự động. + +Sự suy giảm theo thời gian ảnh hưởng đến xếp hạng, không phải xóa cứng. Các bộ nhớ cũ vẫn có thể được gọi lại nếu chúng vẫn đủ liên quan. + +### Q5. Tôi nên chọn giữa cô lập theo `session` hay `bot` như thế nào? + +Trong thực tế: + +- chọn `session` + - khi mỗi cuộc trò chuyện nhóm / trò chuyện riêng tư nên giữ bộ nhớ độc lập + - khi bạn muốn rủi ro rò rỉ chéo phiên thấp hơn +- chọn `bot` + - khi bot nên chia sẻ trải nghiệm dài hạn giữa các phiên + - khi việc gọi lại rộng hơn quan trọng hơn việc phân tách nghiêm ngặt + +Nếu bạn không chắc chắn, hãy bắt đầu với `session`. + +### Q6. Tại sao `!memory export` chỉ xuất phạm vi hiện tại? + +Đó là một ranh giới an toàn có tính toán. + +Việc cho phép xuất mọi cấu hình L1 trong thực thể plugin sẽ làm cho việc rò rỉ dữ liệu chéo phiên trở nên dễ dàng hơn nhiều. Việc hạn chế xuất trong phạm vi hiện tại tuân theo nguyên tắc tiếp xúc tối thiểu. + +### Q7. Điều gì xảy ra nếu runtime không để lộ `_knowledge_base_uuids` trong các biến truy vấn? + +Việc chèn bộ nhớ tự động vẫn hoạt động, nhưng plugin không thể loại bỏ KB bộ nhớ của chính nó khỏi quá trình tiền xử lý RAG thông thường. + +Điều đó có thể dẫn đến việc gọi lại bộ nhớ trùng lặp: + +- một bản sao được chèn bởi chính LongTermMemory +- một bản sao khác được gọi lại lần nữa bởi luồng KB chung của runner + +Vì vậy, đây không phải là một thất bại hoàn toàn, nhưng nó có thể lãng phí ngữ cảnh và làm cho prompt ồn ào hơn. + +### Q8. Tại sao xuất L2 chưa được hỗ trợ? + +SDK hiện cung cấp API `vector_list` để liệt kê phân trang nội dung kho lưu trữ vector. Các bộ nhớ tình tiết L2 có thể được duyệt qua `!memory list [page]` và xóa riêng lẻ qua `!memory forget ` hoặc công cụ `forget`. + +Việc xuất hàng loạt đầy đủ vẫn chưa được thực hiện, nhưng các khối xây dựng đã sẵn sàng. + +### Q9. LongTermMemory và AgenticRAG có bị trùng lặp truy xuất khi cả hai đều được bật không? + +Không, sự trùng lặp đó chính là điều mà thiết kế hiện tại tránh được: + +- LongTermMemory loại bỏ tiền xử lý RAG thông thường của chính nó +- việc gọi lại L2 tự động được xử lý bởi LongTermMemory +- việc truy xuất sâu hơn có thể thực hiện thông qua AgenticRAG + +## Bảng điều khiển Bộ nhớ + +Ngoài lệnh `!memory`, plugin còn đi kèm một trang web **Bảng điều khiển Bộ nhớ** (đăng ký như thành phần Page của plugin) để kiểm tra trực quan và bảo trì. Nó giao tiếp với plugin thông qua các endpoint trang bị giới hạn phạm vi và không bao giờ vượt ra ngoài không gian bộ nhớ đang chọn. + +Bảng điều khiển gồm một thanh bên phạm vi cùng các bảng tab: + +- **Thanh bên không gian bộ nhớ** —— chọn một phạm vi đã biết, hoặc điền `bot_uuid` / `session_name` / `isolation` rồi nhấn **Derive** để tính ra `scope_key` và `user_key` tương ứng. Khu vực **Advanced / Raw** hiển thị các khóa nội bộ. +- **Hồ sơ** —— xem hồ sơ phiên và hồ sơ người nói hiện tại của phạm vi đã chọn. +- **Tình tiết** —— liệt kê (có phân trang) hoặc tìm kiếm ngữ nghĩa các tình tiết L2 của `user_key` hiện tại, lọc theo trạng thái vòng đời; lưu trữ, khôi phục hoặc xóa từng bản ghi tại chỗ.

L2 情景记忆写入 + +- Agent 通过 `remember` 工具写入事件型记忆。 +- 记忆内容会带上时间、重要度、标签、scope 等 metadata。 +- 这些内容进入 LongTermMemory 的 KnowledgeEngine，经过 embedding 后写入向量库。 + +### 3. 对话前自动注入 + +- 在 `PromptPreProcessing` 阶段，EventListener 会先解析当前会话身份。 +- L1 部分： + - 读取 session profile + - 读取当前说话人的 speaker profile + - 把当前说话人身份信息一起注入到 `default_prompt` +- L2 部分： + - 使用当前用户消息做一次情景记忆检索 + - 命中的记忆以“事实数据”形式注入到 prompt + +也就是说，L1 和 L2 都是在模型真正回答前进入上下文，但注入方式不同：L1 走 system prompt，L2 走检索结果块。 + +### 4. 主动检索与调试 + +- 如果自动注入不足，Agent 还可以通过 `recall_memory` 工具主动检索记忆。 +- 开发或排障时，可以使用 `!memory`、`!memory profile`、`!memory search`、`!memory list`、`!memory forget` 查看当前状态。 +- `!memory export` 只导出当前 scope 下的 L1 画像，方便做备份或迁移。 + +## 与 AgenticRAG 的关系 + +如果同时启用了 AgenticRAG： + +- LongTermMemory 会先把自己的 memory KB 从 naive RAG 预处理列表里移除。 +- L2 自动记忆召回仍由 LongTermMemory 自己完成。 +- 同一个 memory KB 仍然可以被 AgenticRAG 的 `query_knowledge` 工具主动访问，用于更深一步的 agentic 检索。 + +这样设计的好处是： + +- 自动记忆召回不会和 naive RAG 重复 +- 长期记忆仍然保留“自动 recall + 主动 query”两条路径 +- 不依赖插件加载顺序来避免重复注入 + +## 为什么暂时不向 Agent 开放元数据过滤 + +虽然底层运行时支持 metadata filter，但本插件目前没有在 Agent 流中直接暴露任意原始元数据过滤能力。 + +原因包括： + +- 不同知识引擎和向量后端没有统一的 metadata schema +- 过滤字段名、值格式、支持的操作符可能各不相同 +- Agent 当前没有稳定的 schema 来源，难以正确构造过滤条件 + +如果未来 LangBot 能为每个知识库提供统一的可过滤元数据字段描述，就可以再考虑开放更通用的 Agent 侧 metadata filter。 + +不过，由于长期记忆插件自己的 memory schema 是稳定的，本插件已经提供了受控的 `recall_memory` 工具入口，支持按说话人、时间范围等固定参数主动检索记忆，而不是让大模型直接拼接底层 raw filter。 + +## 隔离模型 + +支持两种隔离模式： + +- `session`：每个群聊或私聊各自独立 +- `bot`：同一个 bot 下的所有会话共享记忆 + +在当前部署模型下，这通常已经足够，因为插件实例一般会绑定在特定的 LangBot 运行环境或 bot 上。 + +## 隔离规则细节 + +这个插件里实际上有两套相关但不完全相同的“作用域”概念： + +- **session_name**：当前 query / retrieval 链路里传递的会话标识，格式是 `{launcher_type}_{launcher_id}`。 +- **session_key**：插件内部用于 L1 画像存储的 key；如果有 `bot_uuid`，实际会变成 `{bot_uuid}:{launcher_type}_{launcher_id}`，否则退化为 `{launcher_type}_{launcher_id}`。 +- **scope_key / user_key**：真正用于画像存储或 L2 检索隔离的键。 + +### L1 画像怎么隔离 + +L1 画像总是按当前会话范围保存： + +- `session profile` + -

群 A 的记忆不会被群 B 召回 + - 私聊 A 的记忆不会被私聊 B 召回 +- `bot` + - 同一个 bot 下的多个会话共享一套 L2 记忆 + - 适合希望 bot 在不同会话之间共享长期经验的场景 + +如果还带有 `sender_id`，插件也可以优先检索“当前说话人相关”的记忆，再回退到更宽的 scope。 + +### 为什么 L1 和 L2 的隔离看起来不完全一样 + +这是有意为之： + +- L1 更像“当前会话和当前说话人的稳定画像”，天然适合做精细的 session / speaker 级存储。 +- L2 更像“可检索的经验库”，更适合通过 metadata 过滤控制召回范围。 +- 这样既保留了 L1 的精确注入能力，也保留了 L2 的可扩展检索能力。 + +## 使用方法 + +1. 安装并启用本插件。 +2. 使用本插件的 KnowledgeEngine 创建一个 memory knowledge base。 +3. 配置以下参数： + -

我們不使用敘事文本日記作為唯一的記憶事實來源 + - 我們明確劃分了穩定設定檔和片段記憶 + - 我們優先考慮跨會話、發言者和機器人的隔離 + - 我們讓 L2 記憶自然地接入 LangBot 的知識庫/檢索系統，而不僅僅依賴全文閱讀 + +簡而言之： + +- OpenClaw 主要回答：「個人助手應如何保持可讀、可編輯、具反思性的長期記憶？」 +- LongTermMemory 主要回答：「在明確的隔離規則下，跨群組和私聊工作的機器人應如何保持穩定的設定檔狀態和可檢索的經驗記憶？」 + +這兩種方向都沒有絕對的「優劣」。它們針對不同的產品和不同的失效模式進行了優化。 + +## 設計 + +本插件特意貼近 LangBot 現有的擴展點，而不是要求自定義核心補丁。 + +- L1 設定檔作為 JSON 存儲在插件存儲中 +- L2 片段記憶存儲在向量數據庫中 +- 通過附加此插件的 KnowledgeEngine 為每個管道啟用記憶檢索 +- 插件目前假設每個插件實例使用單個記憶知識庫，並透過元數據隔離記憶 + +目前的實現是基於現有的 LangBot 和 SDK API。如果 LangBot 以後添加了更多明確的面向記憶的 API、會話身份 API 或知識庫註冊 API，插件可以簡化，但目前的架構仍然有效。 + +### 向量數據庫後端兼容性 + +L2 片段記憶依賴於任意元數據欄位（`user_key`、`episode_id`、`tags`、`importance` 等）進行隔離和過濾。並非所有 LangBot 向量數據庫後端都支持任意元數據： + +| 後端 | 任意元數據 | LongTermMemory 支持 | +|---------|-------------------|----------------------| +| **Chroma** (預設) | 是 | 完全支持 | +| **Qdrant** | 是 | 完全支持 | +| **SeekDB** | 是 | 完全支持 | +| **Milvus** | 否 (固定 schema: `text`, `file_id`, `chunk_uuid`) | 不支持 | +| **pgvector** | 否 (固定 schema: `text`, `file_id`, `chunk_uuid`) | 不支持 | + +Milvus 和 pgvector 使用固定的列 schema，並會靜默捨棄它們不認識的元數據欄位。這意味著基於元數據的隔離（`user_key` 過濾）和片段記憶指令（`!memory list`、`!memory forget`、`!memory search`）在這些後端上將無法正常工作——過濾器將被忽略，查詢可能會返回不受限的結果。 + +如果您需要使用 LongTermMemory，請使用 Chroma、Qdrant 或 SeekDB 作為您的向量數據庫後端。 + +## 工作原理 + +一個端到端的長期記憶流程包含四個主要部分： + +### 1. L1 設定檔寫入 + +- 智能體使用 `update_profile` 寫入穩定事實 +- 數據作為結構化 JSON 存儲在插件存儲中 +- 設定檔存儲在 `session`（會話）或 `speaker`（發言者）範圍內 + +### 2. L2 片段寫入 + +- 智能體使用 `remember` 寫入事件類記憶 +- 每條記憶都帶有時間戳、重要性、標籤和範圍等元數據 +- 這些記憶透過插件的 KnowledgeEngine 進行向量化並存儲在向量數據庫中 + +### 3. 回應前的自動注入 + +- 在 `PromptPreProcessing` 期間，EventListener 解析當前會話身份 +- 對於 L1： + - 加載共享的會話設定檔 + - 加載當前發言者設定檔 + - 將兩者以及當前發言者身份注入到 `default_prompt` +- 對於 L2： + - 使用當前用戶消息運行一次片段檢索 + - 檢索到的記憶作為事實上下文塊注入 + +因此，L1 和 L2 都會在答案生成前進入模型上下文，但形式不同：L1 作為系統提示詞記憶，L2 作為檢索到的上下文。 + +### 4. 主動查詢和調試 + +- 如果自動注入不足，智能體可以調用 `recall_memory` +- 對於檢查和調試，可以使用 `!memory`、`!memory profile`、`!memory search`、`!memory list` 和 `!memory forget` +- `!memory export` 僅匯出當前範圍的 L1 設定檔，用於備份或遷移 + +## 與 AgenticRAG 的關係 + +當 AgenticRAG 與 LongTermMemory 同時啟用時： + +- LongTermMemory 會從常規 RAG 預處理中移除自己的記憶知識庫 +- 自動 L2 回想仍由 LongTermMemory 自身處理 +- 同一個記憶知識庫仍可透過 AgenticRAG 的 `query_knowledge` 工具進行顯式查詢 + +這避免了重複回想，同時保留了兩條路徑： + +- 自動記憶回想 +- 需要時由智能體發起的更深入檢索 + +## 為什麼沒有智能體端元數據過濾器 + +底層運行時可以支持元數據過濾，但本插件目前未向智能體流程開放任意原始元數據過濾器。 + +原因： + +- 不同的知識引擎和向量後端不共享統一的元數據 schema +- 過濾器欄位名稱、值格式和支持的運算符可能有所不同 +- 智能體目前沒有穩定的 schema 來源來構建可靠的過濾器 + +如果 LangBot 後來提供了一種統一的方式來描述每個知識庫的可過濾元數據欄位，則可以添加智能體端元數據過濾。 + +本插件確實為其自身的穩定記憶 schema 提供了一個受控的回想工具接口。該工具支持選定的過濾器（如發言者和時間範圍），而不會向模型暴露特定於後端的自由格式過濾語法。 + +## 隔離模型 + +支持兩種隔離模式： + +- `session`：每個群聊或私聊擁有獨立的記憶 +- `bot`：同一個機器人下的所有會話共享記憶 + +在當前的部署模型中，這通常已經足夠，因為插件實例通常綁定到特定的 LangBot 運行時/機器人環境。 + +## 隔離規則詳解 + +本插件中有兩個相關但略有不同的範圍概念： + +- **session_name**：透過當前查詢/檢索路徑傳遞的對話身份，格式為 `{launcher_type}_{launcher_id}` +- **session_key**：插件內部的 L1 存儲鍵。當 `bot_uuid` 可用時，它變為 `{bot_uuid}:{launcher_type}_{launcher_id}`；否則退回到 `{launcher_type}_{launcher_id}` +- **scope_key / user_key**：用於設定檔存儲或 L2 檢索隔離的實際鍵 + +### L1 設定檔如何隔離 + +L1 設定檔始終存儲在當前對話範圍內： + +- `session profile` (會話設定檔) + - 當前對話的共享設定檔 + - 對於群組級別或對話級別的穩定上下文很有用 +- `speaker profile` (發言者設定檔) + - 關於當前發言者的穩定事實 + - 對於特定個人的偏好、身份和筆記很有用 + +因此，`!memory export` 僅匯出屬於當前 `session_key` 的設定檔，而不是插件實例中的每個設定檔。 + +### L2 片段記憶如何隔離 + +L2 記憶帶著隔離元數據寫入向量存儲，然後在檢索時進行過濾： + +- `session` + -

Both Workspaces successfully ingest and retrieve distinct markers with the same Host IDs; the Page snapshot succeeds for both.

It does **not** exercise representative writes through Tool, Command, KnowledgeEngine and EventListener, nor interrupted nested episode operations, so those remain release gates. The manifest now declares shared placement, and the in-probe override is kept only so the probe stays runnable against older checkouts. Run the probe with `KnowledgeEngine/LongTermMemory` to reproduce the limited evidence. + +## External connectors + +Dify, FastGPT, and RAGFlow now serialize mutations and fence ambiguous errors per knowledge base within the complete installation binding, without creating a tenant-bearing detached task; one ambiguous knowledge base never blocks its siblings sharing the installation. A durable plugin-storage intent precedes upload; Host file ID, KB ID, upstream ID, dataset, and state are recorded under an installation-bound key when returned. Deletion resolves only the exact mapping for the requested knowledge base — the canonical record, or a record that same knowledge base itself wrote and that carries the older Host revision's file UUID — and refuses missing/pending mappings and mismatched datasets; an absent exact mapping refuses the operation with no provider request and no storage write, and a tombstone is recorded only after upstream acknowledgement. A record written under another knowledge base's id is never adopted: historic collection-keyed data moves to the canonical key only through explicit reconciliation, never a scan-based copy. Only a dispatched mutation whose outcome is unknown fences: a deterministic pre-call validation error and ordinary pre-dispatch cancellation do not. FastGPT and RAGFlow order dispatch and release around that fence: the pre-written protection must be persisted before the mutation is dispatched (persist-before-dispatch is a precondition, not a best effort — a fence whose Host write fails aborts the mutation before any remote call, raises a dedicated error, and leaves no in-process marker behind), and the protection is released only after the provider result was confirmed and the Host result/mapping (or deletion tombstone) has been recorded, so the wrapped operation of a dispatch covers the request, the response validation and that durable write. A dispatch also refuses a knowledge base that is already fenced, so a later successful operation never clears an earlier unresolved operation's fence: a chain that reaches an unresolved step stops there (an unknown RAGFlow GraphRAG outcome no longer lets the RAPTOR trigger's success clear the fence). An unreadable fence store is not read as "no fence": the mutation is refused with the Host failure until the read succeeds, and the failed read is not cached. A mapping also records the connector's normalized upstream target, and deletion refuses a mapping recorded against a different target (or with none recorded) before any remote call. Fences live in Host storage under a knowledge-base-scoped key with an in-process cache, so a restarted worker still refuses that knowledge base, and deleting the knowledge base clears its fence; the plugins also implement `BasePlugin.on_installation_revoked` to drop per-binding process-local locks and fence cache on SDK revisions that dispatch it (never called by langbot-plugin 0.7.4). Shared placement is declared; integrated deletion still waits on the verification listed below. + +The Host may already persist `IngestionResult.document_id` and pass that upstream ID on delete, but this source alone cannot prove which deployed Host revision is used. Provider DELETE acknowledgements here are not yet verified with an authoritative upstream list/readback, and an upload timeout after remote commit leaves a durable pending intent requiring manual reconciliation. Config KB tombstones must not precede cleanup of outstanding mappings; the Host needs to retain the file row until verified upstream absence. For RAGFlow, an acknowledged upload followed by failed parse needs reconciliation rather than blind reupload. Existing connector fixture tests written for deleting arbitrary unrecorded IDs now fail by design; cancellation fixtures with deliberately detached Host commits no longer model the SDK-owned revocable action. Replacement fixture tests cover per-knowledge-base fencing and sibling isolation, fence persistence across a worker restart, fence clearing on knowledge-base deletion, ambiguous provider/transport failures, non-fencing of deterministic validation errors and pre-dispatch cancellation, refusal (and retry) when the persisted fence store cannot be read, deletion refusing a mapping recorded for another upstream target, and the revocation hook. For FastGPT and RAGFlow the fixture tests additionally cover the fence lifecycle: an unpersistable pre-dispatch fence aborting the mutation before any provider request without leaving a stale fence, a response that fails validation (an undecodable body) keeping the knowledge base fenced and refusing the next mutation, a cancellation that lands after the provider acknowledgement but before the Host mapping/tombstone write keeping the fence, an unknown GraphRAG outcome stopping the RAGFlow chain before RAPTOR, and a later successful operation never clearing an earlier unresolved operation's fence. Real upstream A/B ingestion, deletion absence and cancellation/revision proof remain release gates. + +The items above are **certification and release gates, not placement blockers**: an ambiguous upstream outcome needs the same manual reconciliation under dedicated placement, so they do not justify staying dedicated. All three connectors declare shared placement. No published certification is claimed for them yet. + +The real-child two-binding probe `certification-tests/shared_subprocess_probe.py` now also takes a +connector directory: one controller/plugin/component graph attaches two `InstallationBinding` Workspaces +(asserting `SAME_OBJECT_GRAPH=true` inside the child) and runs the same Host ids through +create/ingest/retrieve/delete per binding against local Host and provider fixtures.

The normative contract is +[`langbot-plugin-sdk/docs/stateless-components.md`](https://github.com/langbot-app/langbot-plugin-sdk/blob/main/docs/stateless-components.md): +component objects are process-wide singletons, `initialize()` runs once per worker and sees no tenant config, +configuration and credentials are resolved per invocation, tenant state in a process cache is keyed by the full +installation binding and released in `on_installation_revoked()`, components must be re-entrant, and blocking work +must stay off the shared event loop. Adding the manifest fields alone is not sufficient — source review and +concurrency tests must prove the implementation. + +37 of the 40 plugins here declare shared placement. `Runner/acp-agent-runner`, `Runner/claude-code-agent` and +`Runner/codex-agent` stay dedicated: each launches a process-global daemon hub, symlinks worker-`HOME` credentials +into every run home and shares one workspace root, so serving two installations from one process needs the +Host/SDK broker and duplex-process API first (see `Runner/acp-agent-runner/docs/SHARED_RUNTIME_BLOCKERS.md`); shared +adaptation is deliberately not planned for them, and their dedicated manifests are the supported configuration. + +Every plugin that declares shared placement ships a `SHARED_RUNTIME.md` stating what is per invocation, what is +binding-keyed and released on revocation, and its known limits, plus a test that drives two installation bindings +through one object graph. `misc/*` suites run in CI through `../.github/workflows/plugins-misc-tests.yml` (one venv and one +interpreter per plugin, dependencies from that plugin's `requirements.txt`); Runner plugin suites run through the +isolated-interpreter harness in `Runner/tests/test_migrated_runners.py`.

LangBot provides +the host infrastructure, authorization, facts, and pull APIs; the runner owns +the model-facing agent behavior such as prompt assembly, history selection, +tool loop, RAG orchestration, and optional context compaction. + +## Compatibility + +This plugin tracks the LangBot 4.11.x Runner integration work. Test it with: + +- `langbot-app/LangBot` branch `dev/4.11.x` +- `langbot-app/langbot-plugin-sdk` branch `dev/4.11.x` +- `plugins/Runner` in the same LangBot checkout +- `langbot-app/langbot-agent-control-plane` branch `main` + +## Scope + +This repository does not define the LangBot host protocol. It consumes the +Protocol v1 run context produced by LangBot. The canonical protocol source is +`LangBot/docs/agent-runner-pluginization/PROTOCOL_V1.md`; this README only +documents how Local Agent consumes that contract: + +- `ctx.event`: event-first metadata for the current trigger. +- `ctx.conversation`, `ctx.actor`, `ctx.subject`: current run scope metadata. +- `ctx.input`: current structured input, including text, multimodal contents, + and lightweight attachment/file references. +- `ctx.context`: context handles, inline policy, and available pull APIs. Local + Agent uses the Host history API for conversation history instead of adapter + bootstrap. +- `ctx.resources`: run-scoped authorized models, tools, knowledge bases, skills, + and storage capabilities. +- `ctx.state`: small Host-projected state for the current run. +- `ctx.runtime`: runtime metadata such as deadline, trace id, query id from + migration adapter paths, and Host metadata. +- `ctx.delivery`: host delivery surface and streaming/edit capabilities. +- `ctx.config`: runner binding config. +- `ctx.adapter`: migration adapter fields; not part of Protocol v1 core and not + a place for prompt, history, RAG results, tool schemas, or authorized + resources. + +LangBot does not inline full conversation history by default. When the runner +needs more context, it should use authorized Host APIs through +`RunnerAPIProxy`, for example model, prompt, history, tool, +knowledge-base, state, and storage APIs. + +Runner components should obtain that proxy with `self.get_run_api(ctx)`. +They should not use the legacy `self.plugin` proxy that regular non-runner +plugin components use. +The SDK proxy import path is +`from langbot_plugin.api.proxies.runner import RunnerAPIProxy`. + +## Runner ID + +`plugin:langbot-team/LocalAgent/default` + +## Configuration + +| Field | Type | Required | Default | Description | +| --- | --- | --- | --- | --- | +| model | model-fallback-selector | yes | primary: '', fallbacks: [], reasoning: {} | LLM model with fallbacks | +| timeout | integer | no | 300 | Total runner execution timeout in seconds.

When LangBot exposes +`ctx.context.available_apis.prompt_get`, Local Agent pulls the +post-preprocessing effective prompt through `RunnerAPIProxy.get_prompt()` and +uses it instead of the static default so `PromptPreProcessing` changes are +preserved. If the prompt API is unavailable, Local Agent falls back to +`ctx.config.prompt`. + +`remove-think` is the first supported thinking-output control for Local Agent. +When enabled, the runner passes `remove_think=True` to Host model APIs for both +streaming and non-streaming calls. It is not Pi-style thinking-level control; it +only requests provider thinking output removal when the active Host model +adapter supports that flag. + +Skill support is Host-mediated. When Local Agent advertises +`skill_authoring`, LangBot lists the current pipeline-visible skill facts in +`ctx.resources.skills` and exposes the Host-owned `activate` and +`register_skill` tools according to the same visibility policy. Calling +`activate` returns the full `SKILL.md` instructions as a tool result and +registers the skill package for Box mount resolution under +`/workspace/.skills/`. Local Agent consumes skill facts and tools +through Host APIs; it decides how tool schemas, tool results, prompt context, +or MCP surfaces are presented to the model. + +Legacy singular `knowledge-base` values must be normalized by LangBot +configuration migration before runner execution. Local Agent only reads the +manifest-defined `knowledge-bases` binding config. + +`max-tool-result-chars` is a runner-level safety fallback for model-facing tool +messages. String results, serialized JSON results, and error results are bounded +before they are appended as `role="tool"` messages for the next model request. +Oversized non-error tool results are reported as bounded previews; Local Agent +does not persist runner-owned large-result assets or expose an internal read +tool for them. +Large files and generated assets should be returned by sandbox or Host tools as +sandbox paths, URLs, or other explicit external references, not inline file +content. + +`tool-execution-mode` controls tool calls emitted in the same model turn. +`parallel` runs the batch concurrently and still writes tool-result messages +back in source order. `serial` executes them one by one. + +Tools can return a top-level `terminate: true` runtime hint when the tool action +already completes the user-visible work and the automatic follow-up model call +should be skipped. Local Agent stops early only when every finalized tool result +in that batch sets `terminate: true`; mixed batches continue normally. The hint +is stripped from the model-facing `role="tool"` message so it does not become +business data for the next provider request. + +When a sandbox or Host tool already returns explicit `path` fields, Local Agent +treats those as authoritative sandbox references. If the surrounding result is +large, the model and Host events receive those references plus a bounded preview +only. + +## Context Management + +The local agent should be treated as a runner-owned or hybrid-context runner: + +- LangBot inlines the current event/input and context handles. +- The runner pulls transcript history through the authorized Host history API. +- The runner decides whether to page history, summarize, compact, or construct + a model request from scratch. +- Large files, images, audio, and tool outputs should be consumed as sandbox + paths, URLs, or other explicit references + instead of large inline payloads. + +Local Agent currently uses a runner-owned context pipeline: + +1. Assemble effective prompt, host transcript history, RAG context, and current + structured input. +2. Use the Host-provided model context window from `ctx.runtime.metadata` when + available, capped by the runner binding's `context-window-tokens`. If Host + metadata is unavailable, `context-window-tokens` is the fallback window and + defaults to 200k tokens. +3. Count the final provider-shaped messages through the Host `count_tokens` + API. LangBot implements this with the active model requester; the LiteLLM + requester uses `litellm.token_counter` with the same messages and tool + schemas used for the real model request. Runtime context budgeting fails + closed if the Host does not expose token counting. +4. When the assembled context exceeds the effective input budget + (`window - reserve`, with reserve clamped for small windows), + use the authorized Host model API to generate a structured checkpoint summary, + wrap it in a `system` message containing + `...`, and keep a recent history + tail bounded by `context-keep-recent-tokens`. If Host exposes the state API, + Local Agent persists that summary as a conversation-scoped compaction + checkpoint at `runner.compaction.checkpoint`, anchored by `covers_until`, and + later runs reuse it before pulling transcript entries after that cursor. If + model summarization fails or returns empty content, Local Agent falls back to + a deterministic bounded summary. +5. Re-run the context transform before every model turn, including tool-call + follow-up turns, so tool results and assistant tool calls are budgeted before + the next provider request. +6. If a provider fails before producing any streamed content with a + context-overflow style error, compact the current loop context with a more + aggressive retry budget and retry the model turn once before surfacing + `run.failed`. + +This is not `max-round` behavior. History is not selected by number of rounds; +the runner budgets prompt, current input, summary, and recent history together, +following the Pi-style context threshold and per-turn transform shape. When the +Host does not expose the state API or a checkpoint cannot be parsed, Local Agent +falls back to the previous tail-history behavior. Token counts are still +provided by Host `count_tokens`; there is no runtime heuristic token-count +fallback. + +Pipeline adapter data is intentionally narrow. Local Agent does not consume +`ctx.adapter.extra.prompt`; prompt handoff goes through the run-scoped Host +prompt API when available. New runner logic should prefer event-first context +and Host APIs over adapter fields. + +## Host APIs Consumed + +Model, prompt, history, state, storage, tool, knowledge-base, rerank, and +steering access go through `RunnerAPIProxy`. LangBot validates these calls +with the current `run_id`, run-scoped resource policy / available APIs, and +caller plugin identity. + +Local Agent must not expose the runner process filesystem as an agent +capability. In sandboxed deployments, file access is mediated by Host/sandbox +tools registered in `ctx.resources.tools`; the model can request those tools, +and the runner invokes them through `RunnerAPIProxy.call_tool()`. "Local" here +means the agent loop runs locally as a LangBot plugin, not that the model can +read or write arbitrary files on the runner machine. + +Skill activation uses the same tool path. If Host exposes `activate` in the +run's allowed tools, the model calls `activate` like any other function tool and +Local Agent forwards it through `RunnerAPIProxy.call_tool()`; no separate +runner action is required for skill activation. + +Typical local-agent usage: + +- Invoke authorized LangBot-hosted models. +- Call authorized tools. +- Retrieve authorized knowledge bases and rerank results. +- Page transcript history for the model request. +- Pull authorized steering inputs at turn boundaries. + +The runner must not bypass `ctx.resources` or call host-private managers to +access unauthorized models, tools, knowledge bases, storage, or platform APIs. + +## Capabilities + +- `streaming`: yes +- `tool_calling`: yes +- `knowledge_retrieval`: yes +- `multimodal_input`: yes +- `skill_authoring`: yes +- `interrupt`: yes +- `steering`: yes + +`interrupt` is cooperative. When Host exposes the run ledger API, Local Agent +polls the current run through `RunnerAPIProxy.run_get()` at run boundaries and +streaming event boundaries. If Host has recorded `cancel_requested_at`, the +runner stops and emits `run.failed` with `code="cancelled"`. + +`skill_authoring` means Local Agent can receive LangBot's Host-owned +`ctx.resources.skills` facts plus `activate`/`register_skill` tools when skills +are available. Skills remain owned by LangBot/Box; the runner owns how +model-facing prompts, tool schemas, tool results, or MCP adapters are assembled +from those Host capabilities. + +Local Agent is reentrant and does not keep mutable per-conversation state in +the plugin instance. It can pull Host history each run. When Host state APIs +are available, it persists compacted summary checkpoints through +`RunnerAPIProxy` so later runs can resume from +`runner.compaction.checkpoint`. It does not persist external session IDs or +runner-owned memory outside Host-managed state/storage. + +## Event System Boundary + +This plugin does not implement LangBot EventGateway, event subscription, event +notification, scheduler, or event fanout. Those systems belong to LangBot host +or separate event-focused branches. This runner only consumes the run context +that LangBot delivers through Runner Protocol v1. + +## Current Boundary + +This plugin is the target external implementation of LangBot's local agent +runner. LangBot's internal runner code can be used as reference material, but +its host-private structures must not become plugin API. + +## Contributing + +We welcome contributions. Useful areas include: + +- Protocol v1 adapter fixes +- history/state/storage API consumption +- tool loop and RAG behavior +- multimodal input handling +- focused tests and documentation improvements + +## Native runner migration decisions + +All settings in the Runner descriptor belong to the **per-pipeline Runner binding** +(`ai.runner_config[plugin:langbot-team/LocalAgent/default]` / resolved `binding.runner_config`), not plugin-global settings. +`model.reasoning` is a map from model UUID to a provider-neutral level, default `{}`: +`provider_default`, `disabled`, `enabled`, `minimal`, `low`, `medium`, `high`, `xhigh`, `max`. +The Host must freeze these overrides from the descriptor-declared model selector into +the run authorization snapshot and apply them to an authorized, request-local model +copy on every primary, fallback, tool-follow-up and summary request. The plugin does +not translate vendor parameters or add SDK/wire hints. This requires a Host with that +binding-to-model bridge; a saved map alone is not proof that provider reasoning changed. +`remove-think` controls output filtering, not reasoning effort. + +`date-grounding` defaults to `true`: before token budgeting, the runner appends the +current UTC date and a time-sensitive fact verification reminder to the first system +prompt, or creates one. UTC is explicit, not an inferred user timezone. Set `false` +when a separately managed prompt supplies time grounding. Effective Host prompts take +precedence over static prompts. SDK-valid structured message content and metadata are +preserved; malformed content fails validation rather than disappearing silently. + +Keep the newer defaults when migrating: token budgets and checkpoint compaction replace +`max-round` (there is no rounds-to-tokens conversion); tool results stay bounded at +20,000 characters; run timeout stays 300 seconds; tool iterations stay 100; retrieval +stays bounded and separate from the user message. `timeout=0`/`null` only disables the +plugin-local deadline, never a Host deadline. `retrieval-top-k=5` requests five entries +per KB and, without reranking, keeps five combined chunks; `rerank-top-k=5` bounds +reranked output. These are deliberately not the native unbounded retrieval defaults. + +`tool-execution-mode=parallel` is retained as the new default for independent tools, +with results returned in source order. **Completion order is not execution order:** +side-effecting or dependent calls may race. Select `serial` for ordered writes/actions; +neither mode widens the Host allowlist. Tools, MCP attachments/visibility, skills and +Box session isolation remain Host authority; do not copy them into plugin-global +configuration. Legacy `knowledge-base` and string `model` need explicit migration to +`knowledge-bases` and the model selector. Box scope/history import require Host-specific +migration decisions; token compaction does not import old transcripts or shared files. + +## Box + +`box-enabled`: enables sandbox execution and file tools. `box-session-id-template`: defaults to `{launcher_type}_{launcher_id}` for per-chat reuse; `{global}` shares within the Workspace. Templates also support `{sender_id}`, `{bot_id}`, `{run_id}`, and public request variables. The Runner selects the Box, imports inputs, and explicitly exports the current run outbox on successful completion. diff --git a/plugins/Runner/LocalAgent/readme/README_es_ES.md b/plugins/Runner/LocalAgent/readme/README_es_ES.md new file mode 100644 index 000000000..a972c27dd --- /dev/null +++ b/plugins/Runner/LocalAgent/readme/README_es_ES.md @@ -0,0 +1,62 @@ +# Agente integrado + +## Descripción general + +Agente integrado con modelos de respaldo, herramientas y recuperación de conocimiento. + +## Información del paquete + +- **Runner ID**: `plugin:langbot-team/LocalAgent/default` +- **Versión**: `0.1.0` +- **Repositorio**: [https://github.com/langbot-app/LangBot/tree/master/plugins/Runner/LocalAgent](https://github.com/langbot-app/LangBot/tree/master/plugins/Runner/LocalAgent) + +## Capacidades principales + +- **Activada**: `streaming`, `tool calling`, `knowledge retrieval`, `multimodal input`, `skill authoring`, `interrupt`, `steering` +- **No declarada**: Vacío + +## Configuración + +| Campo | Tipo | Obligatorio | Valor predeterminado | +| --- | --- | --- | --- | +| `model` | `model-fallback-selector` | Sí | `{fallbacks: [], primary: '', reasoning: {}}` | +| `timeout` | `integer` | No | `300` | +| `prompt` | `prompt-editor` | Sí | `[{content: You are a helpful assistant., role: system}]` | +| `remove-think` | `boolean` | No | false | +| `knowledge-bases` | `knowledge-base-multi-selector` | No | `[]` | +| `advanced-settings` | `boolean` | No | `false` | +| `date-grounding` | `boolean` | No | `true` | +| `retrieval-top-k` | `integer` | No | `5` | +| `rerank-model` | `rerank-model-selector` | No | Vacío | +| `rerank-top-k` | `integer` | No | `5` | +| `max-tool-iterations` | `integer` | No | `100` | +| `tool-execution-mode` | `select` | No | `parallel` | +| `max-tool-result-chars` | `integer` | No | `20000` | +| `context-history-fetch-limit` | `integer` | No | `50` | +| `context-window-tokens` | `integer` | No | `200000` | +| `context-reserve-tokens` | `integer` | No | `16384` | +| `context-keep-recent-tokens` | `integer` | No | `20000` | +| `context-summary-tokens` | `integer` | No | `8000` | + +## Permisos del Host + +- **`models`**: `count_tokens`, `invoke`, `stream`, `rerank` +- **`tools`**: `detail`, `call` +- **`knowledge_bases`**: `list`, `retrieve` +- **`history`**: `page` + +## Instalación y uso + +1.

获取预处理后的有效提示词和授权的历史记录。 +2. 组装当前输入、历史、RAG 结果、技能提示和工具定义。 +3. 使用 Host token 计数 API计算上下文预算。 +4. 必要时生成或复用会话级压缩摘要。 +5. 调用模型并处理工具调用，直到得到最终回复或达到迭代上限。 +6. 将流式增量、工具事件、状态更新和最终结果交给 LangBot 投递。 + +## 配置 + +| 字段 |

时，摘要会以会话级 checkpoint 持久化；下次运行可从 checkpoint 游标之后继续拉取历史。 + +如果 provider 在尚未输出内容前返回上下文溢出错误，Local Agent 会使用更激进的预算再压缩一次，并重试当前模型调用一次。Host 不提供 token 计数能力时，运行会失败关闭，不使用不可靠的字符估算替代。 + +## 工具与大结果 + +工具调用通过 Host 授权列表执行。过大的工具结果只向模型提供有界预览；工具明确返回的路径、URL 或其他外部引用会被保留。工具可返回顶层 `terminate: true`，当同批所有工具结果都请求终止时，Local Agent 会跳过额外模型调用并结束当前运行。 + +## 技能支持 + +当 Host 提供技能资源并允许 `activate` 或 `register_skill` 工具时，Local Agent

Host，单纯保存配置不代表推理等级已生效。 +`remove-think` 只控制思考输出过滤，不代表推理强度。 + +`date-grounding=true` 默认在 token 预算计算前注入当前 UTC 日期与时效信息核实提示， +并保留静态或 Host 有效提示词。UTC 不等于推测用户时区；已有独立日期提示时可设为 `false`。 +SDK 支持的结构化提示词内容与消息元数据会保留；无效内容显式报错，不再静默丢弃。 + +迁移采用新默认：token 预算与 checkpoint 压缩替代 `max-round`，不做轮数到 token 的伪换算； +工具结果上限 20000 字符、总运行超时 300 秒、工具跟进上限 100 轮；保留有界且独立的 RAG 上下文。 +`timeout=0`/`null` 只关闭插件本地超时，不能取消 Host 截止时间。`retrieval-top-k=5` 为每个知识库 +请求 5 条，无重排时合并后也最多保留 5 条；有重排时使用 `rerank-top-k=5`。 + +保留 `tool-execution-mode=parallel` 默认以并发执行独立工具，结果仍按源顺序返回。 +**结果排列不代表执行顺序**，有副作用或依赖顺序的操作可能竞争，应选择 `serial`； +两种模式均不能扩大 Host 授权范围。工具、MCP 附件/可见性、技能、Box 会话隔离由 Host 管理， +不可移到插件全局配置。旧 `knowledge-base` 和字符串 `model` 分别需要显式迁移为 +`knowledge-bases` 与模型选择器；旧历史与 Box 文件共享范围必须另行分析，压缩不等于数据导入。 + +## Box 沙箱 + +`box-enabled` 控制是否使用沙箱。`box-session-id-template` 默认 `{launcher_type}_{launcher_id}` 按聊天复用，使用 `{global}` 可在工作区共享，也支持 `{sender_id}`、`{bot_id}`、`{run_id}` 和请求变量。运行器选择 Box 并导入当前附件；成功完成后显式导出本次运行 outbox 的文件。 diff --git

`acp-agent-runner`、`claude-code-agent`、`codex-agent` 已实现 steering：它们在 `run()` 层用统一的轮次循环，在每个轮次完成后排空 `steering_pull`，并复用各自的会话恢复机制（ACP `session/resume`、Codex `thread/resume`、Claude Code `--session-id`）让追问延续同一会话，最终只发出一个终止性 `run.completed`。 + +当前实现的取舍： + +- 注入发生在**轮次边界**（当前轮次完成后），不是 token 级别的中途打断。 +- 追问以文本形式延续（`item.input.to_text()`）；追问自带的附件暂不转发。 +- daemon

Runner Workshop + +[简体中文](README.zh-CN.md) + +A complete, deterministic **Runner** example for LangBot 4.11. It runs +plugin Python handlers directly, with no model, API subscription, or extra runtime +dependency. This is a developer example for the `dev/4.11.x` Host and SDK; +it does not work with older SDKs that lack `Runner`. + +## Two selectable components + +| Component | Events | Behavior | +|---|---|---| +| Community concierge | Member joined/left, message received/reaction, feedback, friend request | Typed handlers, profile lookups, replies, branching, progress and errors | +| Event observer | `*` | A fallback `EBAEvent` handler that records summaries and optionally the typed payload; never calls tools | + +Installing the plugin does **not** activate either component. Create a processor +configuration, select its component in the detail-page header, and save. Add the configuration under **Plugin processor** in a +bot and save; declared events are delivered automatically. Subscriptions run +independently alongside the primary Agent/Pipeline route, and one failed +subscriber does not prevent other deliveries. The observer only receives events +from explicitly bound bots. Old Pipeline `EventListener` hooks are unchanged. + +## Install and try + +1. Use a running LangBot 4.11 Host and matching Plugin Runtime. +2. In this directory, run `lbp build` with that SDK. The package is written to + `dist/langbot-team-RunnerDemo-0.2.1.lbpkg`. +3. Upload it with **Add extension → local plugin installation** in LangBot. +4. Create two **Plugin processor** configurations. On each detail page, select + **Community concierge** or **Event observer** from the component selector. +5. Open the **Configuration** tab on the right, customize settings, and save. +6. Use the in-page event debugger. Select the event type from an example file, + switch the event editor to **Full JSON**, and paste **only its `data` object**. + The surrounding `{ "event_type": ..., "data": ... }` is the HTTP debug payload. +7. Click **Run test**. The plugin executes for real; platform actions use Mock. + Inspect its logs, action parameters/results, run status and elapsed time. + +To receive real platform events, bind the processor configuration to a bot. You can +also create a configuration directly from the bot binding dialog. +Community replies then send real messages. Feedback/reaction/friend-request +handlers record logs only; this example never auto-approves friend requests. + +## Scenarios + +`examples/scenarios.json` enumerates 12 copyable HTTP debug payloads. + +| File | Expected result | +|---|---| +| 01-member-joined | Query actor → query group → welcome reply; 3 traced actions | +| 02-member-left | Warning log; reply only if departure announcements are enabled | +| 03-help | List available `/demo` commands | +| 04-profile | Query the event actor and group, then acknowledge completion | +| 05-slow | Three progress logs over the configured delay, then reply | +| 06-failure | Warning only by default; with failure demo enabled, an error log and failed run | +| 07-feedback | Classify negative feedback; warning and details, no reply | +| 08-reaction | Record added/removed reaction; no reply | +| 09-friend-request | Record the request and a manual-review warning; no approval | +| 10-observer-custom | Observer handles `platform.specific`; enable payload logging to see custom fields | +| 11-echo-with-image | Unicode text is echoed; image type is logged without downloading it | +| 12-ignored-message | Normal non-command message completes without a reply | + +Optional lookup failures are recorded as failed actions plus warning logs. The +welcome flow continues with the event's own data. Reply failures propagate and +fail the run, preserving previous logs. + +## Configuration + +Community settings: output language, welcome text, command prefix, departure +announcements (off by default), demo delay (600 ms by default; clamped to 0–2000), +and intentional failure (off by default). `/demo fail` is an explicit test hook, +not a random error. Welcome text is verbatim configuration and is not translated +automatically when changing output language. + +Observer settings: output language and payload logging (off by default). Payload +logging includes typed event data but excludes the raw platform object. + +## Shared-runtime certification profile + +RunnerDemo declares `execution.sharedRuntime: shared-runtime-v1` and keeps its +runtime modules free of process-wide or mutable module state; configuration and +per-run data stay on `RunnerContext`. `tests/test_shared_runtime.py` reproduces +the two-binding proof locally with the released SDK: one real worker +(`PluginRuntimeController` + the `RunnerDemo` instance + one instance per +component) is attached twice, as workspace-A/installation-A and +workspace-B/installation-B, and both installations are driven concurrently +through the `community` component with distinct configuration, events and +results. The same test detaches one installation and checks that the sibling +graph survives, so a regression to per-installation object graphs fails it +instead of passing vacuously. Only Host/backend RPC responses are fixtures. A +local `lbp build` archive is still unsigned and has no certification comment. +Space approval is the separate gate that may issue and sign a certification +envelope; this repository does not claim that approval or certificate. + +## Development and repeatable verification + +```bash +# Use the matching SDK environment first. +python -m pip install -r requirements-dev.txt +python -m unittest discover -s tests -v +lbp build + +# Optional: install and run all examples through the real Host HTTP API. +# Use a token or API key with resource manage and operate permissions. +export LANGBOT_API_KEY='your-key' +python scripts/smoke.py --base-url http://127.0.0.1:5399 +``` + +`LANGBOT_TOKEN` can be used instead of an API key; optionally set +`LANGBOT_WORKSPACE_ID`. The smoke script installs the package, creates/reuses two +clearly named demo configurations, sets their parameters, executes 12 scenarios and verifies +that debug replies are Mock. It deliberately creates one failed run, then turns +the failure option off in `finally`. It enables departure announcements and +observer payload logging on its demo configurations. It creates no Bot bindings. +The receipt is saved to ignored `data/smoke-results.json`; credentials are never +saved. Re-running adds another set of run records. + +## Source map + +- `components/runner/community.py`: typed `@self.handler(...)` examples. +- `components/runner/observer.py`: generic event fallback handler. +- Matching YAML files: independent component configs, event declarations and permissions. +- `tests/test_processors.py`: all samples, trace pairing, fault handling, Unicode and config isolation. +- `tests/test_shared_runtime.py`: real SDK worker with two installation bindings — object-graph identity, per-binding configuration/results, slot detach. +- `scripts/smoke.py`: actual package installation and Host/runtime integration check. + +The component API exposes `ctx.event`, `ctx.config`, `ctx.run_id`, `ctx.log()`, +`ctx.reply()` and `ctx.get_available_tools()`. Platform and LangBot APIs use `self.plugin` and automatically retain invocation grants. There is no legacy Pipeline Query or +Agent loop to construct; returning from the handler ends that invocation. + +## Full event matrix + +Create a dedicated **Event observer** configuration with payload logging enabled and +no Bot bindings. With the same authentication environment as above, run: + +```bash +python scripts/event_matrix.py --base-url http://127.0.0.1:5399 --processor-id YOUR_PROCESSOR_UUID +``` + +`examples/event-matrix.json` covers all 17 standard events with minimal and +populated payloads, eight extra variants (including empty/image-only messages, +feedback values and temporary bans), and six invalid inputs: 48 cases total. +The script checks typed payload preservation, exactly one completed run per valid +input, persisted run status, no action calls, and rejection of invalid inputs. +It adds debug run records and writes an ignored receipt to +`data/event-matrix-results.json`. It does not install plugins or modify bindings. +This validates the Host/runtime processing path; platform-specific event support +and actual delivery must still be verified against each adapter. + +Observer declares `usages: [agent, event]` and can be selected by either an Agent or a Plugin processor. Community declares `usages: [event]`. Both use the same Runner context and event handlers. diff --git a/plugins/Runner/RunnerDemo/README.zh-CN.md b/plugins/Runner/RunnerDemo/README.zh-CN.md new file mode 100644 index 000000000..87664c6ca

adapter: + +- LangBot remains the control plane. +- The plugin starts an ACP server over stdio, such as `npx -y @zed-industries/codex-acp`, `npx -y @agentclientprotocol/claude-agent-acp@0.62.0`, `opencode acp`, or `npx -y @google/gemini-cli --acp`. +- In daemon mode, a user-side `langbot-runner-daemon` connects outward to the plugin and starts the ACP process on the user's machine. +- The plugin speaks ACP JSON-RPC: `initialize`, `session/new`, `session/load` or `session/resume`, and `session/prompt`. +- ACP `session/update` text chunks are streamed back to LangBot. +- LangBot multimodal input is mapped to ACP prompt content blocks when the selected ACP runtime advertises the matching prompt capability. +- LangBot tools, knowledge bases, and history are exposed through the SDK-owned run-scoped MCP bridge. + +## Runner ID + +`plugin:langbot-team/ACPAgentRunner/default` + +## Configuration + +Common local examples: + +```text +provider = claude-code +location = local +workspace = /path/to/workspace +``` + +```text +provider = codex +location = local +workspace = /path/to/workspace +``` + +For custom ACP commands, set `provider=custom` and `acp-command`, for example: + +```text +provider = custom +location = local +workspace = /path/to/workspace +acp-command = opencode acp +``` + +For a user workstation behind NAT, enable the plugin daemon hub and run the user-side daemon: + +```text +# Plugin config +daemon-enabled = true +daemon-host = 0.0.0.0 +daemon-port = 8766 +daemon-token = +``` + +```bash +cd acp-agent-runner +python daemon.py \ + --url ws://:8766 \ + --daemon-id alice-laptop \ + --token +``` + +Then configure the runner: + +```text +provider = codex +location = daemon +daemon-id = alice-laptop +workspace = /Users/alice/project +``` + +Custom mode is for ACP stdio commands that are not built in, or for users who +accept weaker/no ACP session recovery for a specific runtime: + +```text +provider = custom +location = local +workspace = /path/to/workspace +acp-command = kimi acp +``` + +```text +provider = custom +location = local +workspace = /path/to/workspace +acp-command = agent acp +``` + +```text +provider = custom +location = local +workspace = /path/to/workspace +acp-command = goose acp +``` + +`acp-command` must start an ACP JSON-RPC stdio server, not an interactive-only +CLI. The runner still calls `initialize`, then `session/resume` or +`session/load` when a stored session id exists and the runtime advertises that +capability, otherwise `session/new`. Set `reuse-session=false` to force a fresh +ACP session each run: + +```text +provider = custom +location = local +workspace = /path/to/workspace +acp-command = kimi acp +reuse-session = false +``` + +Useful options: + +- `provider`: built-in ACP launch preset. Current presets are limited to ACP runtimes that advertise `loadSession` or `sessionCapabilities.resume` and have no known public cross-process resume blocker. Use `custom` for anything else. +- `location`: `local`, `remote-ssh`, or `daemon`. +- `workspace`: agent workspace directory. In `remote-ssh` and `daemon` modes this path is on the remote/user machine. +- `advanced-settings`: reveals bridge, timeout, session, and process tuning controls. It only changes form visibility. +- `ssh-target`: SSH target for `remote-ssh`, for example `yhh@101.34.71.12`. +- `ssh-port`: SSH port. Defaults to `22`. +- `ssh-identity-file`: optional private key path on the LangBot host. +- `daemon-id`: stable ID of a connected user-side runner daemon for `location=daemon`. +- `daemon-connect-timeout`: seconds to wait for the selected daemon to come online. +- `acp-command`: optional command override. Required only for `provider=custom`. +- `env-json`: JSON object merged into the process environment. +- `reuse-session`: persists and reuses `external.acp_session_id` when the ACP agent supports `session/resume` or `session/load`. +- `knowledge-bases`: selects the LangBot knowledge bases authorized for retrieval in this runner. +- `langbot-assets-enabled`: injects the LangBot run-scoped MCP bridge into ACP `mcpServers`. +- `langbot-assets-mode`: `auto`, `ephemeral`, or `gateway`. `auto` currently preserves the existing per-run bridge behavior; `gateway` registers the run in the SDK-owned long-lived HTTP MCP gateway. +- `langbot-assets-gateway-port`: optional fixed port for `langbot-assets-mode=gateway`. Use a fixed port when another platform such as Dify needs to register the gateway URL. +- `langbot-assets-gateway-public-url`: optional externally reachable MCP URL, for example `https://example.com/mcp`. + +Headless ACP permission requests are answered with `allow_once` by default. +LangBot does not yet expose an interactive approval UI for these requests. + +## Steering (follow-up input) + +This runner declares `capabilities.steering: true`. When a run is still in +progress and the user sends another message, LangBot absorbs it into the active +run instead of starting a new one. The runner drains these follow-ups at each +turn boundary via `steering_pull` and runs them as additional ACP +`session/prompt` turns that resume the same session (`session/resume` or +`session/load`). The run emits a single terminal `run.completed` once no +follow-ups remain. + +Notes: + +- Follow-ups are injected between turns, not mid-token. +- Follow-up turns currently carry text only; attachments on follow-ups are not + yet forwarded (the first turn still maps full multimodal input as described + below). +- In `daemon` mode follow-ups are still drained (no message loss), but session + continuity across follow-up turns is best-effort. +- Steering only applies when the run has a conversation scope; otherwise the + runner transparently falls back to single-turn execution. + +## Multimodal Input + +The runner accepts LangBot structured input and attachments. It maps them to ACP +`session/prompt` content blocks according to the selected runtime's +`agentCapabilities.promptCapabilities`: + +- inline image base64/data URLs are sent as ACP `image` blocks only when the + runtime advertises image prompt support; +- inline file base64/data URLs are sent as embedded ACP `resource` blocks only + when the runtime advertises embedded context support; +- URL-backed images or files are sent as ACP `resource_link` blocks; +- unsupported inline attachments are not silently dropped; the prompt receives a + short attachment note explaining which content was not sent. + +Provider support still depends on the ACP executable being launched. A runtime +that does not advertise image prompt support can still handle normal text input +and URL resource links, but it will not receive inline image bytes. + +Built-in provider commands are intentionally unpinned and assume the selected +runtime can run on the target machine. Built-in presets must support ACP session +recovery through `loadSession` or `sessionCapabilities.resume`; otherwise this +runner would silently degrade into single-turn execution after each stdio +process exits. + +| Provider | Default ACP command | Verified session recovery signal | +| --- | --- | --- | +| `auggie` | `npx -y @augmentcode/auggie --acp` | `loadSession` | +| `autohand` | `npx -y @autohandai/autohand-acp` | `loadSession`, `session/resume` | +| `claude-code` | `npx -y @agentclientprotocol/claude-agent-acp@0.62.0` | `loadSession`, `session/resume` | +| `codebuddy-code` | `npx -y @tencent-ai/codebuddy-code --acp` | `loadSession` | +| `codex` | `npx -y @zed-industries/codex-acp` | `loadSession`, `session/resume` | +| `deepagents` | `npx -y deepagents-acp` | `loadSession` | +| `dimcode` | `npx -y dimcode acp` | `loadSession`, `session/resume` | +| `dirac` | `npx -y dirac-cli --acp` | `loadSession` | +| `factory-droid` | `npx -y droid exec --output-format acp-daemon` | `loadSession`, `session/resume` | +| `gemini` | `npx -y @google/gemini-cli --acp` | `loadSession` | +| `glm-agent` | `npx -y glm-acp-agent` | `loadSession`, `session/resume` | +| `kilo` | `npx -y @kilocode/cli acp` | `loadSession`, `session/resume` | +| `opencode` | `opencode acp` | `loadSession`, `session/resume` | +| `pi-acp` | `npx -y pi-acp` | `loadSession` | +| `qwen-code` | `npx -y @qwen-code/qwen-code --acp --experimental-skills` | `loadSession`, `session/resume` | + +The following ACP-capable or ACP-adjacent CLIs are not built-in presets because +they do not currently meet the session recovery bar for this runner: + +| Provider | Reason | +| --- | --- | +| `agoragentic` | `initialize` reports `loadSession: false` and no `session/resume`. | +| `cline` | Headless `initialize` did not complete during verification, so session recovery could not be confirmed. | +| `cursor` | Public reports show `loadSession: true` is advertised, but `session/load` fails for ACP-created sessions. | +| `github-copilot` | Registry npx launch did not start a usable ACP binary during verification. | +| `goose` | Upstream docs say ACP providers do not support session resume or fork yet. | +| `kimi` | Public issue reports ACP load/switch starts with blank history even though CLI history exists. | +| `langcli` | No registry/npm-verifiable ACP stdio package was available during verification. | +| `nova` | Headless `initialize` did not complete during verification, so session recovery could not be confirmed. | +| `qoder` | Public report shows ACP-created sessions cannot be loaded across process restarts despite `loadSession: true`. | +| `sigit` | Packaged binary could not be verified in the test environment and no public session recovery evidence was found. | + +Other ACP-compatible runtimes from the public ACP registry can still be used via +`provider=custom` and `acp-command`. DeepSeek's official Deep Code CLI is not a +built-in preset yet because its current public docs describe the interactive +`deepcode` CLI and MCP support, but do not document an ACP stdio mode. + +For a remote Claude ACP process over SSH: + +```text +provider = claude-code +location = remote-ssh +ssh-target = yhh@101.34.71.12 +workspace = /home/yhh/langbot-e2e/acp-workspace +``` + +Remote mode does not connect to a long-running ACP TCP service. LangBot starts +the ACP process itself over SSH: + +```text +LangBot host + -> ssh user@host "cd && exec " + -> ACP JSON-RPC over ssh stdio +``` + +When LangBot assets are enabled, the runner also starts a temporary run-scoped +MCP bridge on the LangBot host and adds an SSH reverse tunnel on the same SSH +connection: + +```text +remote ACP process + -> http://127.0.0.1:/mcp + -> SSH -R tunnel + -> LangBot run-scoped MCP bridge +``` + +The remote host must allow non-interactive SSH login from the LangBot host and +must already have the selected agent runtime installed, authenticated, and +available on `PATH` for non-interactive shells. + +Platform notes: + +- Linux remote: default path. The wrapper uses `bash -lc`, creates the workspace + directory, changes into it, then execs `acp-command`. +- macOS remote: same as Linux when the remote has `bash` and the selected agent + runtime available to non-interactive SSH sessions. If a Homebrew/npm path is + missing, set it through `env-json` or use an absolute command path. +- Windows remote: not identical to Linux/macOS. Configure the hidden + `remote-shell=powershell` key manually; the wrapper uses PowerShell to create + the workspace and run `acp-command`. Windows OpenSSH must support reverse + forwarding for LangBot MCP assets to work. A first-class Windows UI option is + not exposed yet. + +If a network policy blocks SSH reverse forwarding, set +`mcp-bridge-transport=http` plus `mcp-public-url` to a URL reachable from the +remote host, or disable LangBot asset injection with `langbot-assets-enabled=false`. + +## Run-Scoped LangBot Assets + +By default the plugin starts a temporary run-scoped MCP bridge for each run. The +bridge URL and token are injected into ACP `mcpServers`, and the bridge is +stopped when the run finishes. + +In `location=daemon`, the ACP process does not call the plugin's MCP bridge +directly. The user-side daemon starts a localhost HTTP MCP proxy, injects that +local URL into ACP, then forwards MCP JSON-RPC requests over the already-open +WebSocket connection back to the plugin. The plugin handles those requests with +the current run's `RunnerAPIProxy`, so LangBot assets remain scoped by +`run_id` and the Host authorization snapshot. The user's workstation does not +need a public IP or inbound port for this path. +Runner code should import the SDK proxy from +`langbot_plugin.api.proxies.runner`. + +To test the long-lived HTTP MCP gateway path with ACP, set: + +```text +langbot-assets-enabled = true +langbot-assets-mode = gateway +langbot-assets-gateway-port = 8765 +``` + +In gateway mode, the SDK starts one process-long HTTP MCP gateway and registers +each LangBot run with a short-lived run token. ACP receives the gateway MCP URL +and token through `mcpServers` headers, so the model can call stable LangBot +gateway tools without seeing the token. The gateway tool list is stable and +includes: + +- `langbot_list_assets` +- `langbot_get_current_event` +- `langbot_history_page` +- `langbot_retrieve_knowledge` +- `langbot_get_tool_detail` +- `langbot_call_tool` + +Host-authorized platform and event actions are projected through the same MCP +surface as `tool_type=platform` tools. Use `langbot_list_assets` with +`asset_types=["platform_tools"]` to inspect them, then call them through +`langbot_call_tool`. Event-level action targets are frozen by LangBot for the +current run; platform-level actions may accept explicit target IDs. The ACP +process never receives the platform adapter or its credentials directly. + +The stable tool list is intentionally compatible with platforms such as Dify +that cache MCP provider tools. For those platforms, the same gateway can accept +the short-lived `run_token` as a tool argument instead of an HTTP header. +Register the provider URL with the `/mcp` path, for example +`http://:8765/mcp` or the value configured in +`langbot-assets-gateway-public-url`. + +The current LangBot `run_id` is included in the prompt for diagnostics only. ACP agents should follow MCP tool schemas exactly and should not add `run_id` to tool calls unless a specific tool schema asks for it. + +## Complete configuration index + +In addition to the common fields described above, the current runner exposes: + +- `daemon-connect-timeout` for waiting on a selected daemon. +- `langbot-assets-gateway-host`, `langbot-assets-gateway-port`, `langbot-assets-gateway-public-url`, and `langbot-assets-token-ttl` for Asset Gateway mode. +- `ssh-connect-timeout`, `ssh-extra-options`, and `ssh-identity-file` for SSH execution. +- `startup-timeout` and `initialize-timeout` for ACP process startup and handshake deadlines. +- `create-session-if-missing` for recovery fallback behavior. +- `streaming` for incremental output. +- `append-run-scope-prompt` for adding LangBot run-scope guidance. +- `mcp-servers-json` for additional MCP server configuration. + +## Scope + +This plugin intentionally does not implement an agent platform, task board, workspace manager, or provider-specific CLI behavior. Provider setup, login, model selection, and tool permission semantics still belong to the ACP agent executable being launched. + + +## Shared-worker candidate / daemon upgrade + +This version pins `langbot-plugin==0.6.0b5` and remains dedicated; no shared-worker eligibility is claimed. +It is a candidate, not a certificate or proof of vendor execution. Local, +remote-SSH and daemon modes remain available. Native children use the worker's +nsjail/cgroup policy, not the separate Box managed-process quota. + +- Shared native mode defaults to **`/data/workspace`**, an installation-private + writable directory. Explicit native paths must exist and be writable inside + the jail; `/plugin` is read-only. Dedicated/OSS defaults are unchanged. +- Shared daemon listeners require a **different random token per installation** + (at least 32 characters, at least 12 distinct characters; generate with + `python -c 'import secrets; print(secrets.token_urlsafe(32))'`). Length checks + cannot prove randomness or cross-installation uniqueness: provision unique + secrets, do not reuse the example/config default. Loopback is shared between + workers. Assign a unique explicit `daemon-port` per installation and configure + TLS routing for remote clients; port conflicts fail with configuration guidance. +- Upgrade **both `daemon.py` and its entire `pkg/` directory** from this exact + plugin version on the target. Stock b5/older clients are rejected: the bundled + plugin-owned relay negotiates `coding-relay-v1`. No installed SDK is patched. +- A daemon ID cannot replace a connected socket. Jobs/events/MCP/finish belong + to the accepted socket incarnation. Cancellation revokes run tools and waits + for client process-group cleanup before acknowledging, or fences that daemon. + A disconnect cancels and awaits the client's jobs before any reconnect. +- Unresolved shared jobs retain `.pending` markers under + `/data/.coding-relay-v1//`; worker restart does **not** clear + them. Stop and verify all remote jobs on that target before an operator removes + its marker and reconnects. Never rename the target to bypass a fence. An + already dispatched MCP/SSH/upstream side effect is not rolled back by cancel. +- Remote SSH/daemon accounts are **trusted execution targets**, not independent + tenant sandboxes. Terminating local SSH does not prove remote process-tree + exit; use a controlled target and verify remote quiescence before reuse. + POSIX cleanup covers descendants that remain in the launched process group; + deliberately detached processes require target-owner cleanup. +- Install reviewed CLI/SSH binaries at jail-visible locations and provision + installation-owned credentials. These are functional prerequisites, separate + from certification, signing, and two-Workspace live acceptance. Do not relax + global Box policy or use unreviewed automatic installers to satisfy them. diff --git a/plugins/Runner/acp-agent-runner/assets/icon.svg b/plugins/Runner/acp-agent-runner/assets/icon.svg

SDK/Core source was not modified. +- Host inspected: exact public Core `e897c575e048941f68593f61e53f4b451668a1d5`, resolved from the parent release's `core-merge.json` (the compact handoff concatenated its short SHA and version). Initial `e897c5754` lookup returned 422; no conclusion was based on that nonexistent revision. +- New dedicated test: `Runner/certification-tests/test_coding_runner_shared_blockers.py`. Real SDK imports, real loopback WebSocket hub/daemon exchange, real disposable ACP child process and real Codex filesystem preparation. No live daemon, SSH target, vendor model, account or secret is used. +- Historical exact archives are loaded by `PluginArtifactStore.install_package` and checked by `PluginDependencyEnvironmentStore.prepare`, not just a requirements-string comparison. All packaged Python and requirements bytes are compared with the source under review before admission. +- These tests deliberately combine conflicting configurations in one interpreter. They demonstrate unsafe reusable library/plugin behavior; **they do not demonstrate cross-tenant access in a deployed installation-isolated worker**.

The authenticated A socket receives B's `run.start` and prompt/workspace payload. Each Runner skips `hub.start()` once `hub.is_running`, bypassing its existing conflict check. A positive control proves calling `start()` with B would reject. Merely adding that call fails closed on conflict but cannot supply installation ownership or a usable shared listener. +2. **SDK daemon event ownership is absent.** Through two genuine WebSockets authenticated to the hub, daemon B can emit a completed event for A's known job ID; A's iterator accepts it. `api/agent_tools/daemon.py:389-461` discards sender identity for run events/finish and does not compare MCP request sender to job owner. This probe establishes event injection given a known job ID, not discovery of random job IDs or a deployed exploit. +3. **Cancellation has no remote quiescence acknowledgement.** Cancelling a job causes the hub to forget it, then send best-effort `run.cleanup`; an intentionally uncooperative daemon need not stop. No acknowledgement, lease tombstone or quarantine exists. The test does not claim every standard daemon ignores cancellation; it proves the Host cannot certify remote completion from the local cancellation result. +4. **Codex's unique run directory is not isolation.** `_prepare_local_codex_home` creates distinct A/B directories but links/copies worker `CODEX_HOME/auth.json` and the same `sessions` tree into both. The test reads synthetic foreign credentials/session files through B's run home. No real home is inspected. +5. **ACP inherits worker environment and accepts local cwd without Host authority.** Its real `AcpStdioClient` launches a disposable Python child with `env={}`; the child receives a synthetic worker-only secret and runs in the configured temporary cwd. Claude and Codex have the same `env = {**os.environ, **config['env']}` local/SSH launcher pattern (static evidence: `pkg/native_cli.py:628` and `:924`). Their full native launchers are not dynamically exercised by this probe. +6. **All exact old packages fail b5 dependency admission.** None reaches the installer. A version/pin/declaration-only change would hide this admission failure without fixing authority. + +Default test result: **2 controls pass, 10 safety/admission assertions strict-XFAIL**. Enforcing mode: **2 pass, 10 fail**, exit 1. This is a blocked release, not a 12-test certification PASS. SDK Pydantic deprecation warnings are separate from the failures. The initial evidence also retains one corrected test-harness typo (`invoke_tool` versus genuine `call_tool`). + +## Actual b5/Host capability boundary + +`Runner.get_run_api(ctx)` creates an invocation-bound `RunnerAPIProxy`. The public API provides scoped `get_box_status`, `list_boxes`, `acquire_box`, `bind_box`, attachment import/export, and ordinary `call_tool`; **there is no public duplex process start/stdin/stdout/wait/stop API or daemon registry/lease API**. `ctx.api` exists during `Runner.invoke`; `ctx.get_run_api` is not the b5 interface. + +Core's exact `pkg/plugin/box_actions.py` validates the run session/caller and Box capability through authenticated action context. This is the boundary to extend, not a tenant name in Runner configuration. `pkg/box/runner.py:142-158` permits only the `image` option; plugins cannot supply mounts, resource policy or execution identity. Binding checks Workspace membership and prevents switching an already-bound run. + +Although lower-level Box managed-process primitives exist, they are not exposed through the Runner proxy. On the exact release, `pkg/box/service.py:559-561` explicitly rejects Cloud managed processes; `:522-555` enforces network off, and `pkg/box/admission.py` enforces zero managed-process allowance. A one-shot `exec` tool is not an ACP/Codex duplex transport. Using hidden Box credentials, unmanaged background processes, repeated file polling to evade the managed-process gate, or local subprocess fallback would violate those contracts. Network-off also prevents normal provider authentication/model access and ACP npx adapter downloads. + +## Minimal dependency change for parent approval (proposed, not shipped) + +### 1. Host-owned execution targets and run leases + +Add a small execution broker at the authenticated Host boundary. Register `target_ref` records through a supported owner/admin management API, never from arbitrary Runner config. A record binds a backend (`box`, `ssh`, `daemon`), Workspace/installation access policy, credential reference, workspace root, executable/network policy and generation. Derive the effective Workspace, installation, installed artifact and active run from existing authenticated action context + run ledger; callers must not supply authoritative tenant strings. + +Expose these **new** run-scoped SDK operations (names are a proposal, not b5 APIs): + +| Operation | Request additions beyond implicit `run_id` | Response/contract | +|---|---|---| +| `open_run_process` | idempotent `request_id`, granted `target_ref`, argv, relative cwd, explicit env overrides, optional opaque resume handle | opaque process handle, generation and bounded I/O limits; reconcile the request ID if caller disconnects before receiving the handle | +| `write_run_process` | handle, sequence, bounded bytes, EOF flag | idempotent accepted sequence, explicit backpressure | +| `read_run_process` | handle, cursor, byte cap, bounded wait | sequenced stdout/stderr bytes, next cursor, exit state; bounded buffers and no lost event on retry | +| `get_run_process` | handle or open request ID | authoritative lifecycle state, generation, exit status and cleanup/fence status | +| `close_run_process` | handle or open request ID, reason | stop process group, drain/revoke resources, acknowledge quiescence; ambiguity retains a fenced tombstone rather than reporting safe stop | + +Capability discovery may use existing Host-generated available-API metadata; absence must fail before any listener, file write or subprocess. Every operation revalidates active run, installation generation and handle ownership. State must survive or be explicitly invalidated on broker restart/reconcile/uninstall. Process handles cannot be used as resumable conversation IDs; resume handles are separately scoped to installation, target generation and conversation. Cross-run continuation requires Host validation, not a raw vendor session ID. + +### 2. Box backend and policy prerequisite + +Implement the broker against Box-owned process supervision, not the plugin worker filesystem. Do not expose a Box control token/socket URL to plugins. Map `location=local` explicitly to a managed coding target with a documented migration: paths are inside its authorized workspace, not arbitrary Host absolute paths. Keep dedicated behavior unchanged; unsupported old shared configuration gets an explicit migration error, never silent mode removal. + +The coding profile needs an approved scoped managed-process quota and restricted provider/registry egress or preinstalled pinned CLI/adapters plus a model proxy. Do not silently turn on general Cloud network access or lift the existing global sandbox policy. Workspace storage, HOME, XDG caches, CLI credentials and sessions must be provisioned within the authorized target scope. Environment starts from an allowlist; no worker `os.environ`, SSH agent, Docker socket or shared Codex home inheritance. Validate symlinks/path traversal and reserve CLI credential/cache paths from env overrides. Preserve per-conversation resume with Host-scoped storage and explicit concurrent-write control. + +### 3. SSH and daemon backends + +Preserve both modes via the same broker. SSH `target_ref` resolves an approved hostname, host-key policy, secret reference and remote root; run config cannot choose arbitrary hosts/key files or bypass allowlists through extra SSH arguments. Give the remote supervisor the same process-group stop acknowledgement/lease requirements. + +Daemon listeners belong to the trusted broker/operator, not plugin initialization or a process-global SDK key. Enrollment credentials bind installation/target identity; hello-supplied display IDs and tenant strings carry no authority. Bind each connection incarnation and each job to that identity. Validate event, finish, MCP and cancel-ack sender against **job owner + incarnation + generation**. Key all queues/locks by trusted owner and opaque job handle. A known job ID alone must never authorize delivery or tools. Empty tokens are forbidden for shared daemon targets. + +Extend the daemon protocol with bounded queues/output/frame sizes, sequenced frames, cancellation acknowledgement, heartbeat/lease expiry and reconnect reconciliation. Revoke MCP/asset capabilities before returning completion. If the daemon disconnects or cannot prove stop, fence that target and retain unresolved job state; do not route another run into the same mutable session. This is more than renaming `_global_hubs` keys. + +### 4. Runner refactor after dependencies ship + +Keep protocol parsing, streaming, approval prompts, steering, multimodal input and conversation state behavior. Replace local/SSH stdio and daemon launch transport with the above invocation-bound handle. Read the effective installation configuration through a trusted invocation snapshot; do not use process-environment fallback or cached global configuration as authority. Route LangBot tools through the existing per-invocation API; Host-managed MCP/asset leases must close only the owning run and avoid worker-global listener settings. + +First release the SDK/Host/broker contract and approved policy; then implement all three Runner transports. Do not label a package shared-safe if only daemon mode works while local/SSH silently disappear. If explicitly choosing a supported subset later, that is a separately approved product/migration decision, not this repair's completion. + +## Required GREEN and package gates + +1. Run the present assertions unmarked, preserving the historical RED results. Add two-owner same-worker real SDK RPC tests with colliding display/session IDs, conflicting credentials/config, cross-generation handles and hostile daemon event/MCP injection. +2. Exercise actual Box broker process I/O and approved network behavior, not just a Host mock. Test local/SSH/daemon modes, model sessions, continuation, approval, tool access and file import/export parity. +3. Cancel before start acknowledgement, during input/output and during repeated cancellation; prove process-group exit or durable fencing. Cover daemon disconnect/replacement, lease expiry, burst output bounds, worker/Host restart and uninstall. Assert B remains usable when A cancels and no token/session/workspace is shared accidentally. +4. Only after dependencies and behavior pass, bump the then-current versions, pin the real released SDK, add the shared declaration, and build official `lbp` archives outside the repository from a committed snapshot. No new archive is appropriate on b5 alone. +5. Validate exact archive dependency preparation and cache readback without shadow SDK installation, packaged discovery/RPC, independent exact-digest review, normal signing and scoped two-Workspace acceptance. Existing unsigned b3 archives remain rejected; no force install or manifest-only certification. + +## Reproduce locally + +Use a read-only b5 interpreter with pytest/pytest-asyncio, separately from legacy SDK-stub suites: + +```bash +export CODING_RUNNER_RELEASE_DIR=/path/to/retained/runner-release/packages +# Known-blocker inventory, not approval: +$B5_PYTHON -m pytest Runner/certification-tests/test_coding_runner_shared_blockers.py -q +# Actual RED release gate (expected exit 1 until dependencies/implementations exist): +CODING_RUNNER_ENFORCE_SHARED_SAFETY=1 $B5_PYTHON -m pytest \ + Runner/certification-tests/test_coding_runner_shared_blockers.py -q +``` + +If archives are not supplied, the three exact-archive tests skip explicitly; that run cannot establish package admission. Local run evidence includes JUnit/logs, SDK RECORD verification, exact public Host source and archive hashes under `/home/rock/work/coding-runners-shared-evidence/`.

LangBot starts +the ACP process itself over SSH: + +```text +LangBot host + -> ssh user@host "cd && exec " + -> ACP JSON-RPC over ssh stdio +``` + +When LangBot assets are enabled, the runner also starts a temporary run-scoped +MCP bridge on the LangBot host and adds an SSH reverse tunnel on the same SSH +connection: + +```text +remote ACP process + -> http://127.0.0.1:/mcp + -> SSH -R tunnel + -> LangBot run-scoped MCP bridge +``` + +The remote host must allow non-interactive SSH login from the LangBot host and +must already have the selected agent runtime installed, authenticated, and +available on `PATH` for non-interactive shells. + +Platform notes: + +- Linux remote: default path. The wrapper uses `bash -lc`, creates the workspace + directory, changes into it, then execs `acp-command`. +- macOS remote: same as Linux when the remote has `bash` and the selected agent + runtime available to non-interactive SSH sessions. If a Homebrew/npm path is + missing, set it through `env-json` or use an absolute command path. +- Windows remote: not identical to Linux/macOS. Configure the hidden + `remote-shell=powershell` key manually; the wrapper uses PowerShell to create + the workspace and run `acp-command`. Windows OpenSSH must support reverse + forwarding for LangBot MCP assets to work. A first-class Windows UI option is + not exposed yet. + +If a network policy blocks SSH reverse forwarding, set +`mcp-bridge-transport=http` plus `mcp-public-url` to a URL reachable from the +remote host, or disable LangBot asset injection with `langbot-assets-enabled=false`. + +## Run-Scoped LangBot Assets + +By default the plugin starts a temporary run-scoped MCP bridge for each run. The +bridge URL and token are injected into ACP `mcpServers`, and the bridge is +stopped when the run finishes. + +In `location=daemon`, the ACP process does not call the plugin's MCP bridge +directly. The user-side daemon starts a localhost HTTP MCP proxy, injects that +local URL into ACP, then forwards MCP JSON-RPC requests over the already-open +WebSocket connection back to the plugin. The plugin handles those requests with +the current run's `RunnerAPIProxy`, so LangBot assets remain scoped by +`run_id` and the Host authorization snapshot. The user's workstation does not +need a public IP or inbound port for this path. +Runner code should import the SDK proxy from +`langbot_plugin.api.proxies.runner`. + +To test the long-lived HTTP MCP gateway path with ACP, set: + +```text +langbot-assets-enabled = true +langbot-assets-mode = gateway +langbot-assets-gateway-port = 8765 +``` + +In gateway mode, the SDK starts one process-long HTTP MCP gateway and registers +each LangBot run with a short-lived run token. ACP receives the gateway MCP URL +and token through `mcpServers` headers, so the model can call stable LangBot +gateway tools without seeing the token. The gateway tool list is stable and +includes: + +- `langbot_list_assets` +- `langbot_get_current_event` +- `langbot_history_page` +- `langbot_retrieve_knowledge` +- `langbot_get_tool_detail` +- `langbot_call_tool` + +Host-authorized platform and event actions are projected through the same MCP +surface as `tool_type=platform` tools. Use `langbot_list_assets` with +`asset_types=["platform_tools"]` to inspect them, then call them through +`langbot_call_tool`. Event-level action targets are frozen by LangBot for the +current run; platform-level actions may accept explicit target IDs. The ACP +process never receives the platform adapter or its credentials directly. + +The stable tool list is intentionally compatible with platforms such as Dify +that cache MCP provider tools. For those platforms, the same gateway can accept +the short-lived `run_token` as a tool argument instead of an HTTP header. +Register the provider URL with the `/mcp` path, for example +`http://:8765/mcp` or the value configured in +`langbot-assets-gateway-public-url`. + +The current LangBot `run_id` is included in the prompt for diagnostics only. ACP agents should follow MCP tool schemas exactly and should not add `run_id` to tool calls unless a specific tool schema asks for it. + +## Complete configuration index + +In addition to the common fields described above, the current runner exposes: + +- `daemon-connect-timeout` for waiting on a selected daemon. +- `langbot-assets-gateway-host`, `langbot-assets-gateway-port`, `langbot-assets-gateway-public-url`, and `langbot-assets-token-ttl` for Asset Gateway mode. +- `ssh-connect-timeout`, `ssh-extra-options`, and `ssh-identity-file` for SSH execution. +- `startup-timeout` and `initialize-timeout` for ACP process startup and handshake deadlines. +- `create-session-if-missing` for recovery fallback behavior. +- `streaming` for incremental output. +- `append-run-scope-prompt` for adding LangBot run-scope guidance. +- `mcp-servers-json` for additional MCP server configuration. + +## Scope + +This plugin intentionally does not implement an agent platform, task board, workspace manager, or provider-specific CLI behavior. Provider setup, login, model selection, and tool permission semantics still belong to the ACP agent executable being launched. + + +## Shared-worker candidate / daemon upgrade + +This version pins `langbot-plugin==0.6.0b5` and remains dedicated; no shared-worker eligibility is claimed. +It is a candidate, not a certificate or proof of vendor execution. Local, +remote-SSH and daemon modes remain available. Native children use the worker's +nsjail/cgroup policy, not the separate Box managed-process quota. + +- Shared native mode defaults to **`/data/workspace`**, an installation-private + writable directory. Explicit native paths must exist and be writable inside + the jail; `/plugin` is read-only. Dedicated/OSS defaults are unchanged. +- Shared daemon listeners require a **different random token per installation** + (at least 32 characters, at least 12 distinct characters; generate with + `python -c 'import secrets; print(secrets.token_urlsafe(32))'`). Length checks + cannot prove randomness or cross-installation uniqueness: provision unique + secrets, do not reuse the example/config default. Loopback is shared between + workers. Assign a unique explicit `daemon-port` per installation and configure + TLS routing for remote clients; port conflicts fail with configuration guidance. +- Upgrade **both `daemon.py` and its entire `pkg/` directory** from this exact + plugin version on the target. Stock b5/older clients are rejected: the bundled + plugin-owned relay negotiates `coding-relay-v1`. No installed SDK is patched. +- A daemon ID cannot replace a connected socket. Jobs/events/MCP/finish belong + to the accepted socket incarnation. Cancellation revokes run tools and waits + for client process-group cleanup before acknowledging, or fences that daemon. + A disconnect cancels and awaits the client's jobs before any reconnect. +- Unresolved shared jobs retain `.pending` markers under + `/data/.coding-relay-v1//`; worker restart does **not** clear + them. Stop and verify all remote jobs on that target before an operator removes + its marker and reconnects. Never rename the target to bypass a fence. An + already dispatched MCP/SSH/upstream side effect is not rolled back by cancel. +- Remote SSH/daemon accounts are **trusted execution targets**, not independent + tenant sandboxes.

Fill in connection settings from the table and store credentials in secret fields in the admin UI. + +## Security and limitations + +- The runner can use only LangBot resources authorized for the current run. +- By default, Claude Code runs with `--dangerously-skip-permissions` because LangBot does not yet expose an interactive approval flow. Use it only with trusted workspaces and a constrained operating-system account. Set `dangerously-skip-permissions` to false to restore Claude Code's normal permission checks. +- Availability, model abilities, and rate limits depend on the external service. +- See the localized README files under `readme/` for translated guidance. + +- Follow-ups are injected between turns, not mid-token. +- Follow-up turns currently carry text only; attachments on follow-ups are not + yet forwarded. +- Steering only applies when the run has a conversation scope; otherwise the + runner transparently falls back to single-turn execution. + +## Structured interactions + +The runner exposes a real MCP tool named `ask_user_question` through the +run-scoped LangBot MCP bridge. Its standard Claude `tool_use` event is converted +to LangBot's provider-neutral `interaction.requested` contract. The CLI process +is stopped while the user is answering. A card submission starts a new +AgentRun, resumes the same Claude Code session, and sends the answer as the next +authoritative user turn. Claude CLI must complete an MCP call before persisting +a resumable session, so it cannot accept a second result for the old +`tool_use_id` after the process exits. No Python coroutine or Claude process is +kept waiting for the user. + + +## Shared-worker candidate / daemon upgrade + +This version pins `langbot-plugin==0.6.1` and remains dedicated; no shared-worker eligibility is claimed. +It is a candidate, not a certificate or proof of vendor execution. Local, +remote-SSH and daemon modes remain available. Native children use the worker's +nsjail/cgroup policy, not the separate Box managed-process quota. + +- Shared native mode defaults to **`/data/workspace`**, an installation-private + writable directory. Explicit native paths must exist and be writable inside + the jail; `/plugin` is read-only. Dedicated/OSS defaults are unchanged. +- Shared daemon listeners require a **different random token per installation** + (at least 32 characters, at least 12 distinct characters; generate with + `python -c 'import secrets; print(secrets.token_urlsafe(32))'`). Length checks + cannot prove randomness or cross-installation uniqueness: provision unique + secrets, do not reuse the example/config default. Loopback is shared between + workers. Assign a unique explicit `daemon-port` per installation and configure + TLS routing for remote clients; port conflicts fail with configuration guidance. +- Upgrade **both `daemon.py` and its entire `pkg/` directory** from this exact + plugin version on the target. Stock b5/older clients are rejected: the bundled + plugin-owned relay negotiates `coding-relay-v1`. No installed SDK is patched. +- A daemon ID cannot replace a connected socket. Jobs/events/MCP/finish belong + to the accepted socket incarnation. Cancellation revokes run tools and waits + for client process-group cleanup before acknowledging, or fences that daemon. + A disconnect cancels and awaits the client's jobs before any reconnect. +- Unresolved shared jobs retain `.pending` markers under + `/data/.coding-relay-v1//`; worker restart does **not** clear + them. Stop and verify all remote jobs on that target before an operator removes + its marker and reconnects. Never rename the target to bypass a fence. An + already dispatched MCP/SSH/upstream side effect is not rolled back by cancel. +- Remote SSH/daemon accounts are **trusted execution targets**, not independent + tenant sandboxes. Terminating local SSH does not prove remote process-tree + exit; use a controlled target and verify remote quiescence before reuse. + POSIX cleanup covers descendants that remain in the launched process group; + deliberately detached processes require target-owner cleanup. +- Install reviewed CLI/SSH binaries at jail-visible locations and provision + installation-owned credentials. These are functional prerequisites, separate + from certification, signing, and two-Workspace live acceptance. Do not relax + global Box policy or use unreviewed automatic installers to satisfy them. diff --git a/plugins/Runner/claude-code-agent/assets/icon.svg b/plugins/Runner/claude-code-agent/assets/icon.svg new file mode 100644 index 000000000..b3e76d87c --- /dev/null +++ b/plugins/Runner/claude-code-agent/assets/icon.svg @@ -0,0 +1 @@ +Claude Code diff --git a/plugins/Runner/claude-code-agent/components/runner/default.py b/plugins/Runner/claude-code-agent/components/runner/default.py new file mode 100644 index 000000000..b92ccc96d --- /dev/null +++ b/plugins/Runner/claude-code-agent/components/runner/default.py @@ -0,0 +1,9 @@ +"""Claude Code Runner implementation.""" + +from __future__ import annotations + +from pkg.native_cli import NativeClaudeCodeRunner + + +class DefaultRunner(NativeClaudeCodeRunner): + """Default Claude Code runner.""" diff --git a/plugins/Runner/claude-code-agent/components/runner/default.yaml b/plugins/Runner/claude-code-agent/components/runner/default.yaml new file mode 100644 index 000000000..7ae423dcf --- /dev/null +++ b/plugins/Runner/claude-code-agent/components/runner/default.yaml @@ -0,0 +1,231 @@ +apiVersion: langbot/v1 +kind: Runner +metadata: + name: default + label: + en_US: Claude Code + zh_Hans: Claude Code + description: + en_US: Run Claude Code CLI as a LangBot Runner. + zh_Hans: 将 Claude Code CLI 作为 LangBot 运行器运行。 +spec: + usages: [agent] + config: + -

Use it only with trusted workspaces and a constrained operating-system account. Set `dangerously-skip-permissions` to false to restore Claude Code's normal permission checks. +- Availability, model abilities, and rate limits depend on the external service. +- See the localized README files under `readme/` for translated guidance. + +- Follow-ups are injected between turns, not mid-token. +- Follow-up turns currently carry text only; attachments on follow-ups are not + yet forwarded. +- Steering only applies when the run has a conversation scope; otherwise the + runner transparently falls back to single-turn execution. + +## Structured interactions + +The runner exposes a real MCP tool named `ask_user_question` through the +run-scoped LangBot MCP bridge. Its standard Claude `tool_use` event is converted +to LangBot's provider-neutral `interaction.requested` contract. The CLI process +is stopped while the user is answering. A card submission starts a new +AgentRun, resumes the same Claude Code session, and sends the answer as the next +authoritative user turn. Claude CLI must complete an MCP call before persisting +a resumable session, so it cannot accept a second result for the old +`tool_use_id` after the process exits. No Python coroutine or Claude process is +kept waiting for the user. + + +## Shared-worker candidate / daemon upgrade + +This version pins `langbot-plugin==0.6.1` and remains dedicated; no shared-worker eligibility is claimed. +It is a candidate, not a certificate or proof of vendor execution. Local, +remote-SSH and daemon modes remain available. Native children use the worker's +nsjail/cgroup policy, not the separate Box managed-process quota. + +- Shared native mode defaults to **`/data/workspace`**, an installation-private + writable directory. Explicit native paths must exist and be writable inside + the jail; `/plugin` is read-only. Dedicated/OSS defaults are unchanged. +- Shared daemon listeners require a **different random token per installation** + (at least 32 characters, at least 12 distinct characters; generate with + `python -c 'import secrets; print(secrets.token_urlsafe(32))'`). Length checks + cannot prove randomness or cross-installation uniqueness: provision unique + secrets, do not reuse the example/config default. Loopback is shared between + workers. Assign a unique explicit `daemon-port` per installation and configure + TLS routing for remote clients; port conflicts fail with configuration guidance. +- Upgrade **both `daemon.py` and its entire `pkg/` directory** from this exact + plugin version on the target. Stock b5/older clients are rejected: the bundled + plugin-owned relay negotiates `coding-relay-v1`. No installed SDK is patched. +- A daemon ID cannot replace a connected socket. Jobs/events/MCP/finish belong + to the accepted socket incarnation. Cancellation revokes run tools and waits + for client process-group cleanup before acknowledging, or fences that daemon. + A disconnect cancels and awaits the client's jobs before any reconnect. +- Unresolved shared jobs retain `.pending` markers under + `/data/.coding-relay-v1//`; worker restart does **not** clear + them. Stop and verify all remote jobs on that target before an operator removes + its marker and reconnects. Never rename the target to bypass a fence. An + already dispatched MCP/SSH/upstream side effect is not rolled back by cancel. +- Remote SSH/daemon accounts are **trusted execution targets**, not independent + tenant sandboxes. Terminating local SSH does not prove remote process-tree + exit; use a controlled target and verify remote quiescence before reuse. + POSIX cleanup covers descendants that remain in the launched process group; + deliberately detached processes require target-owner cleanup. +- Install reviewed CLI/SSH binaries at jail-visible locations and provision + installation-owned credentials. These are functional prerequisites, separate + from certification, signing, and two-Workspace live acceptance. Do not relax + global Box policy or use unreviewed automatic installers to satisfy them. diff --git a/plugins/Runner/claude-code-agent/readme/README_es_ES.md b/plugins/Runner/claude-code-agent/readme/README_es_ES.md new file mode 100644 index 000000000..e8df92f17 --- /dev/null +++ b/plugins/Runner/claude-code-agent/readme/README_es_ES.md @@ -0,0 +1,64 @@ +# Claude Code Agent + +## Descripción general + +Ejecuta Claude Code CLI como LangBot Runner. + +## Información del paquete + +- **Runner ID**: `plugin:langbot-team/ClaudeCodeAgent/default` +- **Versión**: `0.1.3` +- **Repositorio**: [https://github.com/langbot-app/LangBot/tree/master/plugins/Runner/claude-code-agent](https://github.com/langbot-app/LangBot/tree/master/plugins/Runner/claude-code-agent) + +## Capacidades principales + +- **Activada**: `streaming`, `tool calling`, `knowledge retrieval`, `steering` +- **No declarada**: `multimodal input`, `interrupt` + +## Configuración + +| Campo | Tipo | Obligatorio | Valor predeterminado | +| --- | --- | --- | --- | +| `daemon-enabled` | `boolean` | No | false | +| `daemon-host` | `string` | No | `127.0.0.1` | +| `daemon-port` | `integer` | No | `8767` | +| `daemon-token` | `secret` | No | Vacío | +| `location` | `select` | Sí | `local` | +| `workspace` | `string` | No | Vacío | +| `advanced-settings` | `boolean` | No | false | +| `command` | `string` | No | `claude` | +| `args-json` | `string` | No | `[]` | +| `env-json` | `string` | No | `{}` | +| `ssh-target` | `string` | No | Vacío | +| `ssh-port` | `integer` | No | `22` | +| `daemon-id` | `string` | No | Vacío | +| `timeout` | `integer` | No | `300` | +| `streaming` | `boolean` | No | true | +| `reuse-session` | `boolean` | No | true | +| `dangerously-skip-permissions` | `boolean` | No | true | +| `knowledge-bases` | `knowledge-base-multi-selector` | No | `[]` | +| `langbot-assets-enabled` | `boolean` | No | true | +| `mcp-bridge-transport` | `select` | No | `auto` | +| `mcp-servers-json` | `string` | No | `[]` | + +## Permisos del Host + +- **`tools`**: `detail`, `call` +- **`knowledge_bases`**: `retrieve` +- **`history`**: `page` + +## Instalación y uso + +1.

Both are converted to LangBot's +provider-neutral `interaction.requested` contract, so Lark, DingTalk, and other +delivery adapters can render the same fields and actions. + +The app-server process is stopped while the user is answering. The submission +starts a new AgentRun and resumes the same Codex thread. Codex app-server does +not support replying to an old JSON-RPC tool request from a new process, so the +answer is delivered as the next authoritative user turn rather than injected +as the old tool result. This is a provider transport limitation; the interaction +is still a real model tool call and no process is kept waiting. + +Codex app-server command-execution and file-change approval requests are also +converted to action-only confirmation cards. The previous turn is cancelled +while the user decides. Approval resumes the same thread and grants exactly one +matching retry; a different command or file change requires a new approval. + + +## Shared-worker candidate / daemon upgrade + +This version pins `langbot-plugin==0.6.1` and remains dedicated; no shared-worker eligibility is claimed. +It is a candidate, not a certificate or proof of vendor execution. Local, +remote-SSH and daemon modes remain available. Native children use the worker's +nsjail/cgroup policy, not the separate Box managed-process quota. + +- Shared native mode defaults to **`/data/workspace`**, an installation-private + writable directory. Explicit native paths must exist and be writable inside + the jail; `/plugin` is read-only. Dedicated/OSS defaults are unchanged. +- Shared daemon listeners require a **different random token per installation** + (at least 32 characters, at least 12 distinct characters; generate with + `python -c 'import secrets; print(secrets.token_urlsafe(32))'`). Length checks + cannot prove randomness or cross-installation uniqueness: provision unique + secrets, do not reuse the example/config default. Loopback is shared between + workers. Assign a unique explicit `daemon-port` per installation and configure + TLS routing for remote clients; port conflicts fail with configuration guidance. +- Upgrade **both `daemon.py` and its entire `pkg/` directory** from this exact + plugin version on the target. Stock b5/older clients are rejected: the bundled + plugin-owned relay negotiates `coding-relay-v1`. No installed SDK is patched. +- A daemon ID cannot replace a connected socket. Jobs/events/MCP/finish belong + to the accepted socket incarnation. Cancellation revokes run tools and waits + for client process-group cleanup before acknowledging, or fences that daemon. + A disconnect cancels and awaits the client's jobs before any reconnect. +- Unresolved shared jobs retain `.pending` markers under + `/data/.coding-relay-v1//`; worker restart does **not** clear + them. Stop and verify all remote jobs on that target before an operator removes + its marker and reconnects. Never rename the target to bypass a fence. An + already dispatched MCP/SSH/upstream side effect is not rolled back by cancel. +- Remote SSH/daemon accounts are **trusted execution targets**, not independent + tenant sandboxes. Terminating local SSH does not prove remote process-tree + exit; use a controlled target and verify remote quiescence before reuse. + POSIX cleanup covers descendants that remain in the launched process group; + deliberately detached processes require target-owner cleanup. +- Install reviewed CLI/SSH binaries at jail-visible locations and provision + installation-owned credentials. These are functional prerequisites, separate + from certification, signing, and two-Workspace live acceptance. Do not relax + global Box policy or use unreviewed automatic installers to satisfy them. + +Codex retains authentication and resume files in the installation's own +`$HOME/.codex` (or explicitly configured `CODEX_HOME`). Per-run MCP configuration +remains separate; persisted sessions/auth intentionally remain available across +turns. Concurrent writes to the same resumed session are serialized by a +POSIX file lock in its shared sessions directory. Different accounts/session IDs +remain independent. This is continuity within an installation, not a claim that +Agent configurations sharing an external account are separate security tenants. diff --git a/plugins/Runner/codex-agent/assets/icon.svg b/plugins/Runner/codex-agent/assets/icon.svg new file mode 100644 index 000000000..c8fb1c59f --- /dev/null +++ b/plugins/Runner/codex-agent/assets/icon.svg @@ -0,0 +1,4 @@ + + + + diff --git a/plugins/Runner/codex-agent/components/runner/default.py b/plugins/Runner/codex-agent/components/runner/default.py new file mode 100644 index 000000000..287328e51 --- /dev/null +++ b/plugins/Runner/codex-agent/components/runner/default.py @@ -0,0 +1,9 @@ +"""Codex Runner implementation.""" + +from __future__ import annotations + +from pkg.native_cli import NativeCodexRunner + + +class DefaultRunner(NativeCodexRunner): + """Default Codex runner.""" diff --git a/plugins/Runner/codex-agent/components/runner/default.yaml b/plugins/Runner/codex-agent/components/runner/default.yaml new file mode 100644 index 000000000..fb7283ee1 --- /dev/null +++ b/plugins/Runner/codex-agent/components/runner/default.yaml @@ -0,0 +1,272 @@ +apiVersion: langbot/v1 +kind: Runner +metadata: + name: default + label: + en_US: Codex + zh_Hans: Codex + description: + en_US: Run Codex CLI app-server as a LangBot Runner. + zh_Hans: 将 Codex CLI app-server 作为 LangBot 运行器运行。 +spec: + usages: [agent] + config: + -

Both are converted to LangBot's +provider-neutral `interaction.requested` contract, so Lark, DingTalk, and other +delivery adapters can render the same fields and actions. + +The app-server process is stopped while the user is answering. The submission +starts a new AgentRun and resumes the same Codex thread. Codex app-server does +not support replying to an old JSON-RPC tool request from a new process, so the +answer is delivered as the next authoritative user turn rather than injected +as the old tool result. This is a provider transport limitation; the interaction +is still a real model tool call and no process is kept waiting. + +Codex app-server command-execution and file-change approval requests are also +converted to action-only confirmation cards. The previous turn is cancelled +while the user decides. Approval resumes the same thread and grants exactly one +matching retry; a different command or file change requires a new approval. + + +## Shared-worker candidate / daemon upgrade + +This version pins `langbot-plugin==0.6.1` and remains dedicated; no shared-worker eligibility is claimed. +It is a candidate, not a certificate or proof of vendor execution. Local, +remote-SSH and daemon modes remain available. Native children use the worker's +nsjail/cgroup policy, not the separate Box managed-process quota. + +- Shared native mode defaults to **`/data/workspace`**, an installation-private + writable directory. Explicit native paths must exist and be writable inside + the jail; `/plugin` is read-only. Dedicated/OSS defaults are unchanged. +- Shared daemon listeners require a **different random token per installation** + (at least 32 characters, at least 12 distinct characters; generate with + `python -c 'import secrets; print(secrets.token_urlsafe(32))'`). Length checks + cannot prove randomness or cross-installation uniqueness: provision unique + secrets, do not reuse the example/config default. Loopback is shared between + workers. Assign a unique explicit `daemon-port` per installation and configure + TLS routing for remote clients; port conflicts fail with configuration guidance. +- Upgrade **both `daemon.py` and its entire `pkg/` directory** from this exact + plugin version on the target. Stock b5/older clients are rejected: the bundled + plugin-owned relay negotiates `coding-relay-v1`. No installed SDK is patched. +- A daemon ID cannot replace a connected socket. Jobs/events/MCP/finish belong + to the accepted socket incarnation. Cancellation revokes run tools and waits + for client process-group cleanup before acknowledging, or fences that daemon. + A disconnect cancels and awaits the client's jobs before any reconnect. +- Unresolved shared jobs retain `.pending` markers under + `/data/.coding-relay-v1//`; worker restart does **not** clear + them. Stop and verify all remote jobs on that target before an operator removes + its marker and reconnects. Never rename the target to bypass a fence. An + already dispatched MCP/SSH/upstream side effect is not rolled back by cancel. +- Remote SSH/daemon accounts are **trusted execution targets**, not independent + tenant sandboxes. Terminating local SSH does not prove remote process-tree + exit; use a controlled target and verify remote quiescence before reuse. + POSIX cleanup covers descendants that remain in the launched process group; + deliberately detached processes require target-owner cleanup. +- Install reviewed CLI/SSH binaries at jail-visible locations and provision + installation-owned credentials. These are functional prerequisites, separate + from certification, signing, and two-Workspace live acceptance. Do not relax + global Box policy or use unreviewed automatic installers to satisfy them. + +Codex retains authentication and resume files in the installation's own +`$HOME/.codex` (or explicitly configured `CODEX_HOME`). Per-run MCP configuration +remains separate; persisted sessions/auth intentionally remain available across +turns. Concurrent writes to the same resumed session are serialized by a +POSIX file lock in its shared sessions directory. Different accounts/session IDs +remain independent. This is continuity within an installation, not a claim that +Agent configurations sharing an external account are separate security tenants. diff --git a/plugins/Runner/codex-agent/readme/README_es_ES.md b/plugins/Runner/codex-agent/readme/README_es_ES.md new file mode 100644 index 000000000..7ece5a60c --- /dev/null +++ b/plugins/Runner/codex-agent/readme/README_es_ES.md @@ -0,0 +1,65 @@ +# Codex Agent + +## Descripción general + +Ejecuta Codex CLI como LangBot Runner. + +## Información del paquete + +- **Runner ID**: `plugin:langbot-team/CodexAgent/default` +- **Versión**: `0.1.9` +- **Repositorio**: [https://github.com/langbot-app/LangBot/tree/master/plugins/Runner/codex-agent](https://github.com/langbot-app/LangBot/tree/master/plugins/Runner/codex-agent) + +## Capacidades principales + +- **Activada**: `streaming`, `tool calling`, `knowledge retrieval`, `steering` +- **No declarada**: `multimodal input`, `interrupt` + +## Configuración + +| Campo | Tipo | Obligatorio | Valor predeterminado | +| --- | --- | --- | --- | +| `daemon-enabled` | `boolean` | No | false | +| `daemon-host` | `string` | No | `127.0.0.1` | +| `daemon-port` | `integer` | No | `8768` | +| `daemon-token` | `secret` | No | Vacío | +| `location` | `select` | Sí | `local` | +| `workspace` | `string` | No | Vacío | +| `advanced-settings` | `boolean` | No | false | +| `command` | `string` | No | `codex` | +| `args-json` | `string` | No | `[]` | +| `env-json` | `string` | No | `{}` | +| `ssh-target` | `string` | No | Vacío | +| `ssh-port` | `integer` | No | `22` | +| `daemon-id` | `string` | No | Vacío | +| `timeout` | `integer` | No | `300` | +| `streaming` | `boolean` | No | true | +| `reuse-session` | `boolean` | No | true | +| `approval-policy` | `select` | No | `never` | +| `sandbox-mode` | `select` | No | `danger-full-access` | +| `knowledge-bases` | `knowledge-base-multi-selector` | No | `[]` | +| `langbot-assets-enabled` | `boolean` | No | true | +| `mcp-bridge-transport` | `select` | No | `auto` | +| `mcp-servers-json` | `string` | No | `[]` | + +## Permisos del Host + +- **`tools`**: `detail`, `call` +- **`knowledge_bases`**: `retrieve` +- **`history`**: `page` + +## Instalación y uso + +1.

When `langbot-assets-enabled` is true, this runner registers a short-lived, + run-scoped token before calling the bot and passes it through Coze + `custom_variables` under the key `langbot-assets-input-name` (default + `langbot_asset_run_token`). +2. The bot prompt references it as `{{langbot_asset_run_token}}` and passes it as + the `run_token` argument on every LangBot MCP tool call. +3. The runner removes the token when the run ends. Tool calls without a valid + token are rejected by the gateway. + +The gateway accepts the token via an `Authorization: Bearer` header or via a +`run_token` tool-call argument.

Only trusted administrator-configured endpoints should be used. `auto-save-history` remains `true` by default and accepts only booleans. The old `auto_save_history` runtime alias is retired; migration must explicitly map it to `auto-save-history` and resolve conflicting values.

Generated text (including hidden reasoning) is limited to 1 MiB characters; Coze and Tbox uploads are limited to 10 MiB per file. Existing remote conversation IDs require an explicit scoped import or reset when migrating from native runners. These source changes do not publish or install a new plugin version. + +### Provider identity compatibility (`user-id-source`) + +Per-pipeline Runner parameter, not plugin-global configuration. `sender` remains the default. +A `sender` run whose Host actor is missing or empty is refused before any upstream request, instead of minting a per-run provider user; select `legacy-session` explicitly when a conversation-scoped provider user is intended. +Explicit `legacy-session` preserves native provider identity using trusted Host run context only; +missing identity fails before any upstream request, never falls back to the sender or business params. +`legacy-session` uses `conversation.launcher_type` (`group`/`person`) plus `_` plus the exact `conversation.launcher_id`. Host must project the Query launcher for Coze into those fields, including interaction/resume runs. Older Hosts that leave these fields empty must be upgraded. +Provider conversation/session persistence remains Runner-owned.

The gateway is a +run-token-authorized MCP server (`POST /mcp`, JSON-RPC) exposing the +run-authorized LangBot tools: `langbot_list_assets`, +`langbot_get_current_event`, `langbot_history_page`, +`langbot_retrieve_knowledge`, `langbot_get_tool_detail`, and `langbot_call_tool`. + +### How it works + +1. When `langbot-assets-enabled` is true, this runner registers a short-lived, + run-scoped token before calling the app and passes it through DashScope + `biz_params` under the key `langbot-assets-input-name` (default + `langbot_asset_run_token`). This works for both `agent` and `workflow` app + types; the asset callback needs the **agent** app type (tool-calling). +2. The 百炼 app references that value (e.g. via a prompt/plugin variable bound to + `biz_params`) and passes it as the `run_token` argument on every LangBot MCP + tool call. +3. The runner removes the token when the run ends. Tool calls without a valid + token are rejected by the gateway. + +The gateway accepts the token via an `Authorization: Bearer` header or via a +`run_token` tool-call argument. Use the **`run_token` argument** approach here. + +### Configure 百炼 + +1. In the 百炼 agent app, attach the LangBot Asset Gateway as an MCP service whose + URL routes to the gateway `/mcp` (a public HTTPS URL for 百炼 Cloud). +2. Add an app input/variable bound to `biz_params.langbot_asset_run_token`. +3. In the app prompt, instruct the agent to pass that value as `run_token` on + every LangBot MCP tool call, and to call `langbot_list_assets` first when it + needs to discover the run's assets. + +### Configure LangBot + +Select the DashScope runner and set: + +```text +app-type = agent +api-key = +app-id = <百炼 app id> +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +### Limitations + +- 百炼 Cloud cannot reach `localhost`; use a public HTTPS URL for the gateway + `/mcp` endpoint. +- The run token is short-lived and run-scoped; the app must complete its asset + callbacks within the app run. +- The gateway exposes only the assets permitted by the current run: current + event, history page, knowledge retrieval, tool detail, and tool call. +- The 百炼 app must support attaching an external MCP service and forwarding the + `biz_params` value into the tool call.

Workflow output accepts either `workflow_message.message.content` or the native `text` fallback, without duplicating both. The canonical citation prefix field is `references_quote`; the old seed key `references-quote` was not read by the native runner and is retired (explicitly repair it during migration).

When `langbot-assets-enabled` is true, this runner registers a short-lived, + run-scoped token before calling the app and passes it through DashScope + `biz_params` under the key `langbot-assets-input-name` (default + `langbot_asset_run_token`). This works for both `agent` and `workflow` app + types; the asset callback needs the **agent** app type (tool-calling). +2. The 百炼 app references that value (e.g. via a prompt/plugin variable bound to + `biz_params`) and passes it as the `run_token` argument on every LangBot MCP + tool call. +3. The runner removes the token when the run ends. Tool calls without a valid + token are rejected by the gateway. + +The gateway accepts the token via an `Authorization: Bearer` header or via a +`run_token` tool-call argument. Use the **`run_token` argument** approach here. + +### Configure 百炼 + +1. In the 百炼 agent app, attach the LangBot Asset Gateway as an MCP service whose + URL routes to the gateway `/mcp` (a public HTTPS URL for 百炼 Cloud). +2. Add an app input/variable bound to `biz_params.langbot_asset_run_token`. +3. In the app prompt, instruct the agent to pass that value as `run_token` on + every LangBot MCP tool call, and to call `langbot_list_assets` first when it + needs to discover the run's assets. + +### Configure LangBot + +Select the DashScope runner and set: + +```text +app-type = agent +api-key = +app-id = <百炼 app id> +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +### Limitations + +- 百炼 Cloud cannot reach `localhost`; use a public HTTPS URL for the gateway + `/mcp` endpoint. +- The run token is short-lived and run-scoped; the app must complete its asset + callbacks within the app run. +- The gateway exposes only the assets permitted by the current run: current + event, history page, knowledge retrieval, tool detail, and tool call. +- The 百炼 app must support attaching an external MCP service and forwarding the + `biz_params` value into the tool call.

A validated +`interaction.submitted` event resumes Dify through +`/form/human_input/{form_token}` and `/workflow/{workflow_run_id}/events`. +Workflows that pause again produce a new interaction and can be resumed again. +Forms are emitted as atomic steps: the runner collects one field at a time and +then emits the action buttons. This matches LangBot delivery adapters that +support a single select or an action-only confirmation. + +Provider continuation data is not included in the interaction payload. The +runner stores `form_token`, `workflow_run_id`, the Dify user tag, and field/action +mappings in authorized plugin storage under a random LangBot `interaction_id`. +The continuation is deleted after a successful terminal event or after it is +replaced by a later pause. + +The selected Runner binding must allow interactions, and the delivery +adapter must support the requested field/action shape. Adapters with a smaller +interaction subset deliver the request's plain-text fallback instead. +The current official adapters expose buttons and single-select callbacks; +free-text and file form fields therefore require a future adapter capability +before they can be resumed from those surfaces. + +## Runtime State + +Conversation state is managed through `RunnerContext.state` and `RunnerResult.state_updated`: + +### Reading State + +The runner reads `external.conversation_id` from scoped state: + +```python +conversation_id = ctx.state.conversation.get("external.conversation_id") +``` + +Priority: +1. `ctx.state.conversation["external.conversation_id"]` when it is a Dify UUID +2. Empty string (start a new Dify conversation) + +Host-provided LangBot conversation IDs are intentionally not sent to Dify, +because Dify rejects non-UUID `conversation_id` values. + +### Updating State + +The runner outputs `state.updated` with proper scope: + +```python +yield RunnerResult.state_updated( + ctx.run_id, + "external.conversation_id", + dify_conversation_id, + scope="conversation", +) +``` + +LangBot host persists this state and loads it on the next run. + +## LangBot Asset Callback Through Dify MCP + +Dify can call back into LangBot assets through the SDK Asset Gateway when the +Dify app has an MCP provider registered against the gateway URL. + +### Prerequisites + +- The Dify app must be an Agent app with MCP tools enabled. +- The LangBot runner must be installed from this plugin and selected by the + pipeline as `plugin:langbot-team/DifyAgent/default`. +- The SDK Asset Gateway must be reachable by Dify. For Dify Cloud, this means a + public HTTPS URL that forwards to the gateway `/mcp` endpoint. A temporary + tunnel is fine for testing, but use a stable domain or reverse proxy for + production. +- The Dify app needs a Service API key for LangBot to call `https://api.dify.ai/v1`. + +For Dify Cloud, the MCP provider URL should look like: + +```text +https://example.com/mcp +``` + +### Configure Dify Cloud + +1. Open Dify Cloud and go to **Tools -> MCP**. +2. Create an MCP provider for the LangBot Asset Gateway. +3. Set the provider URL to the public gateway URL, for example + `https://example.com/mcp`. +4. Confirm Dify can discover the LangBot tools. The expected tool set is: + `langbot_list_assets`, `langbot_get_current_event`, + `langbot_history_page`, `langbot_retrieve_knowledge`, + `langbot_get_tool_detail`, and `langbot_call_tool`. +5. Open the target Dify Agent app configuration and attach the LangBot MCP tools. +6. Add a hidden text input variable matching `langbot-assets-input-name`, + defaulting to: + +```text +langbot_asset_run_token +``` + +7. Add prompt guidance telling the app to pass that input value as the + `run_token` argument on every LangBot MCP tool call. A minimal prompt pattern + is: + +```text +For every LangBot MCP tool call, set run_token exactly to: +{{langbot_asset_run_token}} +Call langbot_list_assets first when you need to discover available LangBot +assets for the current run. +``` + +8. Use a tool-compatible chat model. For example, `gpt-4o-mini` works for this + flow. Avoid models that reject Dify's tool result message format; `o3-mini` + has been observed to fail with: + +```text +Unsupported value: 'messages[3].role' does not support 'function' with this model. +``` + +### Configure LangBot + +Select the Dify runner on the LangBot pipeline and set: + +```text +base-url = https://api.dify.ai/v1 +api-key = +app-type = agent +timeout = 120 +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-gateway-request-timeout = 60 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +The runner registers a run-scoped token before calling Dify and removes it when +the run ends. Tool calls without a valid token are rejected by the gateway. + +The public Dify MCP provider URL must route to this same gateway instance. The +runner only injects the short-lived token into Dify inputs; it does not create +or update the Dify MCP provider. + +### Verify the Flow + +Use LangBot Debug Chat or another real LangBot run. Do not rely on Dify Cloud +preview alone, because preview does not automatically receive a live +`langbot_asset_run_token`. + +Send a prompt like: + +```text +Call LangBot MCP tool langbot_list_assets first, using the injected run_token. +If the tool call succeeds, reply only LANGBOT_DIFY_MCP_OK. +If the token is missing or invalid, reply RUN_TOKEN_FAILED. +``` + +A passing run should show the sentinel response in LangBot and backend logs +similar to: + +```text +assistant: requested tools: langbot_list_assets +``` + +### Limitations + +- Dify Cloud cannot reach `localhost` or a private LAN gateway. Use public HTTPS + for the MCP provider URL. +- Temporary tunnel URLs such as `trycloudflare.com` are only suitable for + testing. When the tunnel stops or changes, the Dify MCP provider URL becomes + invalid. +- The run token is short-lived and run-scoped. It is injected only when LangBot + calls Dify through this runner, then stopped when the run finishes. +- Dify Cloud preview calls usually fail for LangBot MCP tools unless a valid + token from a live LangBot run is supplied manually. +- The Dify app prompt must consistently pass `run_token` to every LangBot MCP + tool call. Missing or invalid tokens are rejected by the gateway. +- Model compatibility matters. The Dify Agent model must support the function + or tool message roles produced by Dify's tool executor. +- The gateway exposes only the assets permitted by the current LangBot run: + current event, history page, knowledge retrieval, tool detail, and tool call. +- The gateway lifetime is tied to the LangBot process and configured port. Port + conflicts or process restarts will break the public MCP endpoint until the + proxy points at the new live gateway. +- Keep the gateway behind HTTPS and avoid logging or exposing run tokens.

This +relies on SDK single-installation worker fencing, not distributed compare-and-swap. +Expired/consumed failures are retained in scoped plugin storage until normal +installation cleanup; this

This matches LangBot delivery adapters that +support a single select or an action-only confirmation. + +Provider continuation data is not included in the interaction payload. The +runner stores `form_token`, `workflow_run_id`, the Dify user tag, and field/action +mappings in authorized plugin storage under a random LangBot `interaction_id`. +The continuation is deleted after a successful terminal event or after it is +replaced by a later pause. + +The selected Runner binding must allow interactions, and the delivery +adapter must support the requested field/action shape. Adapters with a smaller +interaction subset deliver the request's plain-text fallback instead. +The current official adapters expose buttons and single-select callbacks; +free-text and file form fields therefore require a future adapter capability +before they can be resumed from those surfaces. + +## Runtime State + +Conversation state is managed through `RunnerContext.state` and `RunnerResult.state_updated`: + +### Reading State + +The runner reads `external.conversation_id` from scoped state: + +```python +conversation_id = ctx.state.conversation.get("external.conversation_id") +``` + +Priority: +1. `ctx.state.conversation["external.conversation_id"]` when it is a Dify UUID +2. Empty string (start a new Dify conversation) + +Host-provided LangBot conversation IDs are intentionally not sent to Dify, +because Dify rejects non-UUID `conversation_id` values. + +### Updating State + +The runner outputs `state.updated` with proper scope: + +```python +yield RunnerResult.state_updated( + ctx.run_id, + "external.conversation_id", + dify_conversation_id, + scope="conversation", +) +``` + +LangBot host persists this state and loads it on the next run. + +## LangBot Asset Callback Through Dify MCP + +Dify can call back into LangBot assets through the SDK Asset Gateway when the +Dify app has an MCP provider registered against the gateway URL. + +### Prerequisites + +- The Dify app must be an Agent app with MCP tools enabled. +- The LangBot runner must be installed from this plugin and selected by the + pipeline as `plugin:langbot-team/DifyAgent/default`. +- The SDK Asset Gateway must be reachable by Dify. For Dify Cloud, this means a + public HTTPS URL that forwards to the gateway `/mcp` endpoint. A temporary + tunnel is fine for testing, but use a stable domain or reverse proxy for + production. +- The Dify app needs a Service API key for LangBot to call `https://api.dify.ai/v1`. + +For Dify Cloud, the MCP provider URL should look like: + +```text +https://example.com/mcp +``` + +### Configure Dify Cloud + +1. Open Dify Cloud and go to **Tools -> MCP**. +2. Create an MCP provider for the LangBot Asset Gateway. +3. Set the provider URL to the public gateway URL, for example + `https://example.com/mcp`. +4. Confirm Dify can discover the LangBot tools. The expected tool set is: + `langbot_list_assets`, `langbot_get_current_event`, + `langbot_history_page`, `langbot_retrieve_knowledge`, + `langbot_get_tool_detail`, and `langbot_call_tool`. +5. Open the target Dify Agent app configuration and attach the LangBot MCP tools. +6. Add a hidden text input variable matching `langbot-assets-input-name`, + defaulting to: + +```text +langbot_asset_run_token +``` + +7. Add prompt guidance telling the app to pass that input value as the + `run_token` argument on every LangBot MCP tool call. A minimal prompt pattern + is: + +```text +For every LangBot MCP tool call, set run_token exactly to: +{{langbot_asset_run_token}} +Call langbot_list_assets first when you need to discover available LangBot +assets for the current run. +``` + +8. Use a tool-compatible chat model. For example, `gpt-4o-mini` works for this + flow. Avoid models that reject Dify's tool result message format; `o3-mini` + has been observed to fail with: + +```text +Unsupported value: 'messages[3].role' does not support 'function' with this model. +``` + +### Configure LangBot + +Select the Dify runner on the LangBot pipeline and set: + +```text +base-url = https://api.dify.ai/v1 +api-key = +app-type = agent +timeout = 120 +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-gateway-request-timeout = 60 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +The runner registers a run-scoped token before calling Dify and removes it when +the run ends. Tool calls without a valid token are rejected by the gateway. + +The public Dify MCP provider URL must route to this same gateway instance. The +runner only injects the short-lived token into Dify inputs; it does not create +or update the Dify MCP provider. + +### Verify the Flow + +Use LangBot Debug Chat or another real LangBot run. Do not rely on Dify Cloud +preview alone, because preview does not automatically receive a live +`langbot_asset_run_token`. + +Send a prompt like: + +```text +Call LangBot MCP tool langbot_list_assets first, using the injected run_token. +If the tool call succeeds, reply only LANGBOT_DIFY_MCP_OK. +If the token is missing or invalid, reply RUN_TOKEN_FAILED. +``` + +A passing run should show the sentinel response in LangBot and backend logs +similar to: + +```text +assistant: requested tools: langbot_list_assets +``` + +### Limitations + +- Dify Cloud cannot reach `localhost` or a private LAN gateway. Use public HTTPS + for the MCP provider URL. +- Temporary tunnel URLs such as `trycloudflare.com` are only suitable for + testing. When the tunnel stops or changes, the Dify MCP provider URL becomes + invalid. +- The run token is short-lived and run-scoped. It is injected only when LangBot + calls Dify through this runner, then stopped when the run finishes. +- Dify Cloud preview calls usually fail for LangBot MCP tools unless a valid + token from a live LangBot run is supplied manually. +- The Dify app prompt must consistently pass `run_token` to every LangBot MCP + tool call. Missing or invalid tokens are rejected by the gateway. +- Model compatibility matters. The Dify Agent model must support the function + or tool message roles produced by Dify's tool executor. +- The gateway exposes only the assets permitted by the current LangBot run: + current event, history page, knowledge retrieval, tool detail, and tool call. +- The gateway lifetime is tied to the LangBot process and configured port. Port + conflicts or process restarts will break the public MCP endpoint until the + proxy points at the new live gateway. +- Keep the gateway behind HTTPS and avoid logging or exposing run tokens. Tune + `langbot-assets-token-ttl` to the minimum value that still covers expected + Dify tool latency. + +## Workflow Inputs + +Workflow inputs are passed through `ctx.adapter.extra.params`: + +```python +# Runner uses adapter params as Dify inputs +inputs = dict((ctx.adapter.extra or {}).get("params") or {}) +``` + +Legacy input variables are derived from context: + +| Variable | Source | +| --- | --- | +| langbot_user_message_text | `ctx.input.to_text()` | +| langbot_session_id | `ctx.conversation.session_id` or `ctx.run_id` | +| langbot_conversation_id | `ctx.state.conversation.get("external.conversation_id")` when it is a Dify UUID | +| langbot_msg_create_time | `ctx.adapter.extra.params["msg_create_time"]` if provided | + +## Example Usage + +### Chat/Agent Mode with Stateful Session + +LangBot host provides state snapshot: + +```python +ctx = RunnerContext( + run_id="run_001", + input=AgentInput(text="Hello"), + config={ + "base-url": "https://api.dify.ai/v1", + "api-key": "app-xxx", + "app-type": "chat", + }, + state=AgentRunState( + conversation={"external.conversation_id": "4f4f8c1b-b1f4-4c9f-9e9f-0f144af69f10"}, + ), + params={}, +) +``` + +Runner will use the Dify UUID as the Dify conversation ID, maintaining session +continuity. + +### Workflow Mode with Custom Inputs + +```python +ctx = RunnerContext( + run_id="run_002", + input=AgentInput(text="Process this"), + config={ + "base-url": "https://api.dify.ai/v1", + "api-key": "app-yyy", + "app-type": "workflow", + }, + params={ + "custom_var": "value1", + "workflow_input": "data", + }, +) +``` + +Runner passes `params` to Dify workflow inputs. + +## Replaced Runner + +Migrated from `dify-service-api` in LangBot. + +### Key Changes + +1. **Config is static only**: No `conversation_id` in config +2. **State via protocol**: Use `ctx.state` and `state.updated` +3. **Inputs via adapter params**: Use `ctx.adapter.extra.params` for workflow inputs +4. **Scoped state**: `external.conversation_id` with `scope="conversation"` + +### Provider identity compatibility (`user-id-source`) + +Per-pipeline Runner parameter, not plugin-global configuration. `sender` remains the default. +A `sender` run whose Host actor is missing or empty is refused before any upstream request, instead of minting a per-run provider user; select `legacy-session` explicitly when a conversation-scoped provider user is intended. +Explicit `legacy-session` preserves native provider identity using trusted Host run context only; +missing identity fails before any upstream request, never falls back to the sender or business params. +`legacy-session` uses `conversation.launcher_type` (`group`/`person`) plus `_` plus the exact `conversation.launcher_id`.

The gateway is a run-token-authorized MCP server +(`POST /mcp`, JSON-RPC) exposing the run-authorized LangBot tools: +`langbot_list_assets`, `langbot_get_current_event`, `langbot_history_page`, +`langbot_retrieve_knowledge`, `langbot_get_tool_detail`, and `langbot_call_tool`. + +### How it works + +1. When `langbot-assets-enabled` is true, this runner registers a short-lived, + run-scoped token before calling the flow and injects it into the run via a + tweak: it sets the `input_value` of the component named by + `langbot-assets-input-name` (default `langbot_asset_run_token`) to the token. +2. The flow's Agent reads that value and passes it as the `run_token` argument on + every LangBot MCP tool call. +3. The runner removes the token when the run ends. Tool calls without a valid + token are rejected by the gateway. + +The gateway accepts the token via an `Authorization: Bearer` header or via a +`run_token` tool-call argument. Use the **`run_token` argument** approach here. + +### Build the flow + +1. Add a **Text Input** (or similar) component whose name/id matches + `langbot-assets-input-name`. The runner sets its `input_value` to the token + each run. (Leave its value empty by default.) +2. Add an **MCP Tools / MCP Connection** component: + - Transport: streamable HTTP. + - URL: the public URL routing to the gateway `/mcp`, e.g. `https://example.com/mcp`. +3. Add an **Agent** component, attach the MCP Tools, and wire the token component + into the Agent so its instructions pass `run_token` on every LangBot tool call, + for example: + + ```text + For every LangBot MCP tool call, set run_token exactly to the provided + LangBot run token. Call langbot_list_assets first to discover available + LangBot assets for the current run. + ``` + +### Configure LangBot + +Select the Langflow runner and set: + +```text +base-url = http://localhost:7860 +api-key = +flow-id = +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +The public MCP URL in the flow's MCP component must route to this same gateway +instance. The runner only injects the short-lived token into the flow tweak; it +does not create or update the flow's MCP component. + +### Limitations + +- A remote/cloud Langflow that cannot reach `localhost` needs a public HTTPS URL + for the gateway `/mcp` endpoint. +- The run token is short-lived and run-scoped; the flow must complete its asset + callbacks within the flow run. +- The gateway exposes only the assets permitted by the current run: current + event, history page, knowledge retrieval, tool detail, and tool call. +- The flow must have a component whose name/id matches `langbot-assets-input-name` + for the tweak injection to land; otherwise the token never reaches the Agent. + Verify the `tools/list` handshake against your gateway when setting this up. + +## Legacy Runner + +Migrated from `langflow-api` in LangBot. + + +## Dedicated runtime placement + +This release is unsigned and dedicated.

When `langbot-assets-enabled` is true, this runner registers a short-lived, + run-scoped token before calling the flow and injects it into the run via a + tweak: it sets the `input_value` of the component named by + `langbot-assets-input-name` (default `langbot_asset_run_token`) to the token. +2. The flow's Agent reads that value and passes it as the `run_token` argument on + every LangBot MCP tool call. +3. The runner removes the token when the run ends. Tool calls without a valid + token are rejected by the gateway. + +The gateway accepts the token via an `Authorization: Bearer` header or via a +`run_token` tool-call argument. Use the **`run_token` argument** approach here. + +### Build the flow + +1. Add a **Text Input** (or similar) component whose name/id matches + `langbot-assets-input-name`. The runner sets its `input_value` to the token + each run. (Leave its value empty by default.) +2. Add an **MCP Tools / MCP Connection** component: + - Transport: streamable HTTP. + - URL: the public URL routing to the gateway `/mcp`, e.g. `https://example.com/mcp`. +3. Add an **Agent** component, attach the MCP Tools, and wire the token component + into the Agent so its instructions pass `run_token` on every LangBot tool call, + for example: + + ```text + For every LangBot MCP tool call, set run_token exactly to the provided + LangBot run token. Call langbot_list_assets first to discover available + LangBot assets for the current run. + ``` + +### Configure LangBot + +Select the Langflow runner and set: + +```text +base-url = http://localhost:7860 +api-key = +flow-id = +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +The public MCP URL in the flow's MCP component must route to this same gateway +instance. The runner only injects the short-lived token into the flow tweak; it +does not create or update the flow's MCP component. + +### Limitations + +- A remote/cloud Langflow that cannot reach `localhost` needs a public HTTPS URL + for the gateway `/mcp` endpoint. +- The run token is short-lived and run-scoped; the flow must complete its asset + callbacks within the flow run. +- The gateway exposes only the assets permitted by the current run: current + event, history page, knowledge retrieval, tool detail, and tool call. +- The flow must have a component whose name/id matches `langbot-assets-input-name` + for the tweak injection to land; otherwise the token never reaches the Agent. + Verify the `tools/list` handshake against your gateway when setting this up. + +## Legacy Runner + +Migrated from `langflow-api` in LangBot. + + +## Dedicated runtime placement + +This release is unsigned and dedicated.

It parses streaming `item`/`end` + objects, the configured JSON `output-key`, or plain text. JSON objects without + that key are serialized whole; arrays fall back to the original text. +- `ignore` waits for HTTP response headers, accepts **all 2xx statuses**, closes + the response without reading its body, and completes without a chat reply. + It is **not** background fire-and-forget: configure n8n's Webhook to **Respond + Immediately**. Non-2xx responses and timeouts still fail. +- `timeout` (default 120 seconds) bounds the entire webhook request, including + headers and reply body, in addition to HTTPX's per-phase timeout. Reply data is + capped at 1,048,576 characters, matching the native runner's runtime limit. +- Ignored responses end the run immediately after acceptance. Asset tokens are + revoked then, so a background workflow **cannot** keep using the run's LangBot + resources. Leave `langbot-assets-enabled=false` unless callbacks are explicitly + authorized and finish before the webhook responds. + +Configuration moves from `ai.n8n-service-api` to +`ai.runner_config["plugin:langbot-team/N8nAgent/default"]`; this is pipeline Runner +configuration, not plugin-instance settings. All eleven native fields retain +their names, including `response-handling`. The placeholder webhook URL is no +longer a default: an explicit working URL is required. Authentication remains +none/Basic/JWT/custom-header, with JWT `sub=n8n-webhook` and one-hour expiry. +Secrets are not trimmed. Error bodies and exception details are deliberately +not echoed to chat/logs; use the n8n service's diagnostics to investigate errors. + +Native aiohttp Basic auth used Latin-1; HTTPX defaults to UTF-8. Both are now +supported through `basic-encoding`. Keep the plugin default `utf-8` for existing +plugin setups; select `latin1` when preserving native Basic-auth bytes, especially +for non-ASCII credentials. ASCII credentials produce identical bytes in both. +Encoding differences are not assumed to be a security improvement. + +The modern Host/SDK architecture is retained, with these explicit differences: + +- The plugin streams each item rather than batching every eight native items; + Host delivery decides how the channel displays chunks. Incremental UTF-8 + decoding preserves characters split across network packets. +- Empty **reply** output remains an explicit `n8n.empty_response` failure rather + than a native empty message. It is never a failure in **ignore** mode. +- `msg_create_time` is always present (default empty string); provided values, + including zero, are preserved. Business parameters come from + `ctx.adapter.extra.params`, not the old unrestricted `query.variables` object. +- `external.conversation_id` and `external.session_id` live in Host conversation + state; generated IDs do not automatically reuse native session UUIDs. `user_id` + still derives from the SDK actor, whereas native used launcher/chat identity. + **These are identity/scope changes, not proven security improvements.** Existing + workflows require an explicit scoped state/identity migration or approved reset; + this change does not migrate state or claim remote conversation continuity. +- Reserved identity fields cannot be overwritten by adapter parameters. HTTP + redirects are not followed automatically; configure the final webhook URL. +- No native history/max-round loop is restored: native n8n sent current input, + not local-agent history. Host history/tools/knowledge callbacks are a separate, + opt-in capability; migration must not silently enable them. + +## LangBot Asset Callback Through n8n MCP Client Tool + +n8n can call back into LangBot assets through the SDK Asset Gateway, the same +mechanism the Dify runner uses. The gateway is a run-token-authorized MCP server +(`POST /mcp`, JSON-RPC) that exposes the run-authorized LangBot tools: +`langbot_list_assets`, `langbot_get_current_event`, `langbot_history_page`, +`langbot_retrieve_knowledge`, `langbot_get_tool_detail`, and `langbot_call_tool`. + +### How it works + +1. When `langbot-assets-enabled` is true, this runner registers a short-lived, + run-scoped token before calling the webhook and injects it into the webhook + payload under `langbot-assets-input-name` (default `langbot_asset_run_token`). +2. The n8n workflow consumes the webhook, reads that field, and passes it as the + `run_token` argument on every LangBot MCP tool call. +3. The runner removes the token when the run ends. Tool calls without a valid + token are rejected by the gateway. + +The gateway accepts the token either via an `Authorization: Bearer` header or via +a `run_token` tool-call argument. Because n8n credentials are static and cannot +carry a per-run header, use the **`run_token` argument** approach (same as Dify). + +### Build the n8n workflow + +The n8n workflow behind the webhook must use an **AI Agent** node with an +**MCP Client Tool** node attached: + +1. **Webhook** trigger node — receives the LangBot payload, including + `langbot_asset_run_token`. Respond when the last node finishes so the asset + callbacks happen inside the request window (before the token is revoked). +2. **MCP Client Tool** node (n8n version >= 1.2, `defaultVersion` 1.3): + - Transport: **HTTP Streamable**. + - Endpoint: the public URL that routes to the gateway `/mcp`, e.g. + `https://example.com/mcp`. + - Authentication: **None** (the token travels as a tool argument, not a header). +3. **AI Agent** node — attach the MCP Client Tool. In the system prompt, instruct + the agent to pass `run_token` on every LangBot tool call, for example: + + ```text + For every LangBot MCP tool call, set run_token exactly to: + {{ $json.langbot_asset_run_token }} + Call langbot_list_assets first when you need to discover available LangBot + assets for the current run. + ``` + +4. Return the agent output in the webhook response (streaming `type: item`/`end` + chunks, or a JSON object keyed by `output-key`). + +### Configure LangBot + +Select the n8n runner on the LangBot pipeline and set: + +```text +webhook-url = +auth-type = none +timeout = 120 +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-gateway-request-timeout = 60 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +The public MCP endpoint configured in the n8n MCP Client Tool node must route to +this same gateway instance. The runner only injects the short-lived token into +the webhook payload; it does not create or update the n8n MCP Client Tool node. + +### Limitations + +- n8n Cloud (and any n8n that cannot reach `localhost`) needs a public HTTPS URL + for the gateway `/mcp` endpoint. Temporary tunnel URLs are for testing only. +- The run token is short-lived and run-scoped, injected only while LangBot calls + the webhook and revoked when the run finishes. The workflow must complete its + asset callbacks within the webhook request. +- The gateway exposes only the assets permitted by the current run: current + event, history page, knowledge retrieval, tool detail, and tool call. +- n8n's MCP Client Tool uses the official MCP SDK (`StreamableHTTPClientTransport`). + Verify the `initialize` + `tools/list` handshake against your gateway once when + setting it up. + +## Legacy Runner + +Migrated from `n8n-service-api` in LangBot. + +### Provider identity compatibility (`user-id-source`) + +Per-pipeline Runner parameter, not plugin-global configuration. `sender` remains the default. +A `sender` run whose Host actor is missing or empty is refused before any upstream request, instead of minting a per-run provider user; select `legacy-session` explicitly when a conversation-scoped provider user is intended. +Explicit `legacy-session` preserves native provider identity using trusted Host run context only; +missing identity fails before any upstream request, never falls back to the sender or business params. +`legacy-session` uses `conversation.launcher_type` (`group`/`person`) plus `_` plus the exact `conversation.launcher_id`. Host must project the native Query.session launcher into those fields, including interaction/resume runs. Older Hosts that leave these fields empty must be upgraded. +Provider conversation/session persistence remains Runner-owned.

It parses streaming `item`/`end` + objects, the configured JSON `output-key`, or plain text. JSON objects without + that key are serialized whole; arrays fall back to the original text. +- `ignore` waits for HTTP response headers, accepts **all 2xx statuses**, closes + the response without reading its body, and completes without a chat reply. + It is **not** background fire-and-forget: configure n8n's Webhook to **Respond + Immediately**. Non-2xx responses and timeouts still fail. +- `timeout` (default 120 seconds) bounds the entire webhook request, including + headers and reply body, in addition to HTTPX's per-phase timeout. Reply data is + capped at 1,048,576 characters, matching the native runner's runtime limit. +- Ignored responses end the run immediately after acceptance. Asset tokens are + revoked then, so a background workflow **cannot** keep using the run's LangBot + resources. Leave `langbot-assets-enabled=false` unless callbacks are explicitly + authorized and finish before the webhook responds. + +Configuration moves from `ai.n8n-service-api` to +`ai.runner_config["plugin:langbot-team/N8nAgent/default"]`; this is pipeline Runner +configuration, not plugin-instance settings. All eleven native fields retain +their names, including `response-handling`. The placeholder webhook URL is no +longer a default: an explicit working URL is required. Authentication remains +none/Basic/JWT/custom-header, with JWT `sub=n8n-webhook` and one-hour expiry. +Secrets are not trimmed. Error bodies and exception details are deliberately +not echoed to chat/logs; use the n8n service's diagnostics to investigate errors. + +Native aiohttp Basic auth used Latin-1; HTTPX defaults to UTF-8. Both are now +supported through `basic-encoding`. Keep the plugin default `utf-8` for existing +plugin setups; select `latin1` when preserving native Basic-auth bytes, especially +for non-ASCII credentials. ASCII credentials produce identical bytes in both. +Encoding differences are not assumed to be a security improvement. + +The modern Host/SDK architecture is retained, with these explicit differences: + +- The plugin streams each item rather than batching every eight native items; + Host delivery decides how the channel displays chunks. Incremental UTF-8 + decoding preserves characters split across network packets. +- Empty **reply** output remains an explicit `n8n.empty_response` failure rather + than a native empty message. It is never a failure in **ignore** mode. +- `msg_create_time` is always present (default empty string); provided values, + including zero, are preserved. Business parameters come from + `ctx.adapter.extra.params`, not the old unrestricted `query.variables` object. +- `external.conversation_id` and `external.session_id` live in Host conversation + state; generated IDs do not automatically reuse native session UUIDs. `user_id` + still derives from the SDK actor, whereas native used launcher/chat identity. + **These are identity/scope changes, not proven security improvements.** Existing + workflows require an explicit scoped state/identity migration or approved reset; + this change does not migrate state or claim remote conversation continuity. +- Reserved identity fields cannot be overwritten by adapter parameters. HTTP + redirects are not followed automatically; configure the final webhook URL. +- No native history/max-round loop is restored: native n8n sent current input, + not local-agent history. Host history/tools/knowledge callbacks are a separate, + opt-in capability; migration must not silently enable them. + +## LangBot Asset Callback Through n8n MCP Client Tool + +n8n can call back into LangBot assets through the SDK Asset Gateway, the same +mechanism the Dify runner uses. The gateway is a run-token-authorized MCP server +(`POST /mcp`, JSON-RPC) that exposes the run-authorized LangBot tools: +`langbot_list_assets`, `langbot_get_current_event`, `langbot_history_page`, +`langbot_retrieve_knowledge`, `langbot_get_tool_detail`, and `langbot_call_tool`. + +### How it works + +1. When `langbot-assets-enabled` is true, this runner registers a short-lived, + run-scoped token before calling the webhook and injects it into the webhook + payload under `langbot-assets-input-name` (default `langbot_asset_run_token`). +2. The n8n workflow consumes the webhook, reads that field, and passes it as the + `run_token` argument on every LangBot MCP tool call. +3. The runner removes the token when the run ends. Tool calls without a valid + token are rejected by the gateway. + +The gateway accepts the token either via an `Authorization: Bearer` header or via +a `run_token` tool-call argument. Because n8n credentials are static and cannot +carry a per-run header, use the **`run_token` argument** approach (same as Dify). + +### Build the n8n workflow + +The n8n workflow behind the webhook must use an **AI Agent** node with an +**MCP Client Tool** node attached: + +1. **Webhook** trigger node — receives the LangBot payload, including + `langbot_asset_run_token`. Respond when the last node finishes so the asset + callbacks happen inside the request window (before the token is revoked). +2. **MCP Client Tool** node (n8n version >= 1.2, `defaultVersion` 1.3): + - Transport: **HTTP Streamable**. + - Endpoint: the public URL that routes to the gateway `/mcp`, e.g. + `https://example.com/mcp`. + - Authentication: **None** (the token travels as a tool argument, not a header). +3. **AI Agent** node — attach the MCP Client Tool. In the system prompt, instruct + the agent to pass `run_token` on every LangBot tool call, for example: + + ```text + For every LangBot MCP tool call, set run_token exactly to: + {{ $json.langbot_asset_run_token }} + Call langbot_list_assets first when you need to discover available LangBot + assets for the current run. + ``` + +4. Return the agent output in the webhook response (streaming `type: item`/`end` + chunks, or a JSON object keyed by `output-key`). + +### Configure LangBot + +Select the n8n runner on the LangBot pipeline and set: + +```text +webhook-url = +auth-type = none +timeout = 120 +langbot-assets-enabled = true +langbot-assets-gateway-host = 0.0.0.0 +langbot-assets-gateway-port = 8765 +langbot-assets-gateway-request-timeout = 60 +langbot-assets-token-ttl = 3600 +langbot-assets-input-name = langbot_asset_run_token +``` + +The public MCP endpoint configured in the n8n MCP Client Tool node must route to +this same gateway instance. The runner only injects the short-lived token into +the webhook payload; it does not create or update the n8n MCP Client Tool node. + +### Limitations + +- n8n Cloud (and any n8n that cannot reach `localhost`) needs a public HTTPS URL + for the gateway `/mcp` endpoint. Temporary tunnel URLs are for testing only. +- The run token is short-lived and run-scoped, injected only while LangBot calls + the webhook and revoked when the run finishes. The workflow must complete its + asset callbacks within the webhook request. +- The gateway exposes only the assets permitted by the current run: current + event, history page, knowledge retrieval, tool detail, and tool call. +- n8n's MCP Client Tool uses the official MCP SDK (`StreamableHTTPClientTransport`). + Verify the `initialize` + `tools/list` handshake against your gateway once when + setting it up. + +## Legacy Runner + +Migrated from `n8n-service-api` in LangBot. + +### Provider identity compatibility (`user-id-source`) + +Per-pipeline Runner parameter, not plugin-global configuration. `sender` remains the default. +A `sender` run whose Host actor is missing or empty is refused before any upstream request, instead of minting a per-run provider user; select `legacy-session` explicitly when a conversation-scoped provider user is intended. +Explicit `legacy-session` preserves native provider identity using trusted Host run context only; +missing identity fails before any upstream request, never falls back to the sender or business params. +`legacy-session` uses `conversation.launcher_type` (`group`/`person`) plus `_` plus the exact `conversation.launcher_id`. Host must project the native Query.session launcher into those fields, including interaction/resume runs. Older Hosts that leave these fields empty must be upgraded. +Provider conversation/session persistence remains Runner-owned. Configuration migration does not import old conversation IDs, threads, transcripts, pending forms or files; finish/cancel pending work or perform a separately authorized state migration. Changing identity on an existing stored provider conversation requires an explicit reset/migration decision. + + +## Dedicated runtime placement + +This release is unsigned and dedicated.

**RunnerDemo** at `31c3119` (its evidence test plus the component-order fix) and **WeKnoraAgent** at `b085fdf`, all 0.2.1. LangRAG fences a cancelled caller's dispatched vector mutation and a reply whose count is not a nonnegative integer again, and telemetry failures no longer fail the operation they describe; LocalAgent's tree differs only in removed tests and its lockfile version. RunnerDemo's tree adds its in-tree two-binding test and README notes; WeKnoraAgent's narrows the `SHARED_RUNTIME.md` identity paragraph to what the client actually sends. `misc/GeneralParsers` sits outside this ledger: its trimmed test tree moved it to 0.1.9. + +**Re-integrated at `e48fb85` after the certification rejection:** **DifyDatasetsConnector**, **FastGPTConnector** and **RAGFlowConnector** at 0.2.1 and **LangRAG** at 0.2.2 refuse a mutation whose persisted fence store cannot be read (the failed read is not cached), share one byte-identical `dispatched()` helper that fences before dispatch and clears the fence on a deterministic answer, and bind every recorded document mapping to the connector's normalized upstream target, so deletion refuses a mapping from another upstream before any remote call. **CozeAgent**, **DifyAgent**, **N8nAgent** and **TboxAgent** at 0.2.1 and **WeKnoraAgent** at 0.2.2 resolve upstream identities from the current invocation's installation binding and refuse in a shared worker that has none (five byte-identical `scoped_identity.py` files); Dify additionally accepts a legacy-owned human-input continuation once and rewrites it with the current owner. Evidence: certification suite `146 passed`; LangRAG `19` through pytest and through the CI unittest runner; the shared agents' identity suites executed in CI by the isolated-interpreter harness; all five KnowledgeEngine archives built locally (`DifyDatasetsConnector-0.2.1.lbpkg`). The Windows review host cannot complete the SDK's POSIX-only RPC/file-transfer stage, so that stage remains CI-only. + +**Follow-up at `88adecd`:** the five shared agents (Coze/Dify/N8n/Tbox 0.2.2, WeKnora 0.2.3) no longer fall back to a per-run vendor identity — a `sender`-mode run without a trusted Host actor is refused with the plugin's own `.identity_unavailable` code before any upstream client is built, and no computed identity contains a run id or a worker revision (WeKnora previously resolved its identity after constructing its client and now validates first, like the other four). `http-certification-tests/test_isolation.py` proves the refusal class and code, that `run()` reports a single `run.failed` carrying it, and that the vendor client class is never constructed; the 36 READMEs of the four `user-id-source` plugins and the five `SHARED_RUNTIME.md` files document the rule. Local evidence: 7/7 isolated plugin suites, 21/21 isolation certification cases, 570 passed with only the 6 known Windows-only vendor-worker failures, ruff clean. `deerflow-agent` and `langflow-agent` still carry an uncalled `_get_user_tag` with the old per-run fallback; it never reaches a vendor and was left untouched. + +**Follow-up at `057ace8` (second rejection of FastGPTConnector and RAGFlowConnector):** both at 0.2.2 now make the pre-dispatch fence a precondition and release it only after the result is recorded — a failed Host write of the fence raises `FencePersistError` and aborts before any remote call (previously it was logged and the request was sent anyway, leaving a worker that had fenced the knowledge base in memory with no durable record), `dispatched()` refuses a knowledge base that is already fenced (`FencedKnowledgeBaseError`), and the wrapped operation covers the provider request, the response validation and the durable mapping/tombstone write, so an undecodable body or a cancellation landing after the acknowledgement keeps the knowledge base fenced. RAGFlow's GraphRAG/RAPTOR `except Exception` swallow is gone: a provider-answered non-zero code is a resolved answer while an unresolved outcome propagates and stops the chain, so RAPTOR's success can no longer clear GraphRAG's fence. Certification is `156 passed` with 10 new cases, each shown to fail against the pre-change code. `DifyDatasetsConnector` keeps the previous best-effort persist and release-on-return behaviour: its 0.2.1 passed review and its artifact was deliberately left unchanged, so the stricter lifecycle is not asserted for it in the shared fixture. + +**Follow-up at `23e0717` (third rejection of the same two connectors):** FastGPTConnector and RAGFlowConnector at 0.2.3 close three more findings. (1) `is_ambiguous_http_failure` released the protection for every HTTP status; it now releases only for a protocol-confirmed rejection — a 4xx response, or a connection that was never established — and keeps it for 5xx/gateway answers, so a 500 arriving after a possible commit no longer lets later mutations run over an unknown remote state (the FastGPT upload and delete handlers raise `AmbiguousMutationError` for those and report a resolved rejection only for a 4xx). (2) The first fence load was cached per installation without a lock while operations lock per knowledge base, so a snapshot whose read began before a sibling's clear could be installed afterwards and, because the binding was then marked loaded, block an already-resolved knowledge base indefinitely; the read is now single-flight under a per-binding lock and is discarded and re-read (bounded) when the fence generation changed under it. (3) RAGFlow mixed the knowledge-base identity with the collection identity: ingestion keyed config, mappings, locks and fences on `context.get_collection_id()` while creation and deletion used `knowledge_base_id`, so one knowledge base could hold two identities, lose mutual exclusion, and leave deletion unable to find the uploaded record; everything now keys on `context.knowledge_base_id`, `_kb_identity` prefers that attribute over the collection getter, and records already written under the collection key are migrated after a unique legacy match (an ambiguous match refuses and asks for reconciliation). Certification is `177 passed` (21 new cases), each shown to fail against the pre-change code. `DifyDatasetsConnector` and `LangRAG` remain untouched: the shared classifier's 5xx rule is therefore not applied to DifyDatasets, which passed its own review. + +**Follow-up at `52465b4` (FastGPTConnector 0.2.4):** the third rejection named the mixed knowledge-base/collection identity for RAGFlow only, but the host contract shows both connectors had it. `LangBot/src/langbot/pkg/rag/knowledge/kbmgr.py` puts `'knowledge_base_id': kb.uuid` and `'collection_id': kb.collection_id or kb.uuid` into the ingestion and retrieval contexts, while `on_knowledge_base_create` and `call_rag_delete_document` always pass `kb.uuid`; the SDK's `get_collection_id()` returns `collection_id or knowledge_base_id`, so a knowledge base bound to an existing vector collection gave ingestion a different key from creation and deletion — two locks, two fences and a document mapping that deletion could not find. FastGPT now keys the stored config, the upload-intent check, the pending intent, the created mapping, the deletion tombstone and the dispatch identity on `context.knowledge_base_id`, and `_kb_identity` prefers an argument's `knowledge_base_id` over its collection getter; records an earlier revision wrote under the collection key are migrated after a unique legacy match (an ambiguous match refuses). Its retrieval path needs no change: it is not serialized and reads only context creation settings. Certification is `180 passed` (three new cases, each failing before the change), and the two bundles' shared functions are now identical modulo docstrings — `is_ambiguous_http_failure`, `_load_fences`, `_read_fences`, `_bump_fence_generation`, `dispatched`, `fence`, `clear_fence`, `_kb_identity`, `_legacy_document`, `_migrate_legacy`, `_load_document`, `_save_document`. + +**Follow-up at `504cc46` (fourth rejection of the same two connectors):** the scan-based legacy migration the two previous rounds added was itself unsafe and is now removed from both bundles (FastGPTConnector 0.2.5, RAGFlowConnector 0.2.4). With a mapping recorded for knowledge base A and none for B, a delete under B adopted A's current record, copied A's configuration under B's key and — when the upstream target and dataset matched — deleted A's upstream document. `ConfigStore._legacy_document`, `ConfigStore._migrate_legacy` and the `_load_document` branch that called them are deleted; `_load_document` resolves only the exact mapping of the requested knowledge base (its canonical record, or a record that same knowledge base itself wrote and that carries the older Host revision's file UUID, still refusing an ambiguous match) and refuses when there is none, with no provider request and no storage write, so an ingest also no longer mistakes another knowledge base's pending record for its own intent. Historic collection-keyed data now moves to the canonical key only through explicit reconciliation. Certification replaces the two migration cases per plugin with a cross-knowledge-base deletion case (which fails against the pre-change code: `delete_document('B', 'shared-doc')` returned True and dispatched A's delete) and a no-false-intent case; the suite stays at 180 passed. The two notes above describe the migration this commit withdraws — they record history, not current behaviour. + +Thirty-seven source candidates declare both `shared-runtime-v1` and `stateless-v1` (the 22 misc plugins joined at `98c0957`); three stay dedicated (the three native coding Runners, whose process-local daemon hubs, shared workspace root and worker-HOME credentials cannot serve two installations from one process). The four KnowledgeEngine plugins moved from dedicated to shared candidate: their locks and fences are keyed by (installation binding, knowledge-base identity), persisted in installation-bound Host storage, released on installation revocation, and only a dispatched mutation with an unknown outcome fences. Ambiguous upstream mutations still need manual reconciliation, but that requirement is identical under dedicated and shared placement and is not a placement blocker. None is asserted certified or production-shared. The source tree identities include integration-only SDK requirement corrections: the four Runner candidates from `8bb55ec` now require `langbot-plugin>=0.7.4,<0.8`, and LangRAG now requires the same instead of `==0.6.1`; their source trees therefore intentionally differ from the lane tips. CI and contract corrections later changed some source trees; the per-plugin tree column identifies the current PR head, not the earlier lane tips. + +**misc adaptation at `98c0957`:** all 22 `misc/*` plugins and the three uncertified Runner agents now declare `shared-runtime-v1` + `stateless-v1`. Each resolves tenant configuration and credentials per invocation, keys process-cached tenant state by the full installation binding (`instance_uuid:workspace_uuid:installation_uuid`, runtime revision excluded so an upgrade does not orphan rows) and releases it in `on_installation_revoked()`, carries that same scope token in its durable row keys (host row keys are `[instance_uuid, workspace_uuid, owner_type, owner, key]` and have no installation dimension), re-enters `bind_invocation(handler, config=…, binding=…)` for detached tenant work and registers it per binding, and moved blocking IO off the shared event loop (`async` clients or `to_thread`); one shared mutable default argument was fixed. Evidence: one suite per plugin, all passing, each fix recording the assertion that fails against the pre-change source (several reproduced against a HEAD copy, e.g. PowerContext's installation B posting installation A's token, DailyLimit's two installations writing one row, WordFSRS's two installations sharing one deck row, WebSearch's leaked default list), plus `.github/workflows/misc-tests.yml` running every misc suite in its own venv and interpreter. `Runner/{dashscope,deerflow,langflow}-agent` gained per-plugin suites and lost an uncalled per-run identity helper; `Runner/acp-agent-runner`, `claude-code-agent` and `codex-agent` remain dedicated by design. Known limits are stated per plugin (for example WordFSRS leaves pre-existing legacy deck rows unmigrated, so a placement switch starts empty; WebSearch's site adapters stay synchronous but run inside a worker thread). Declaring the markers is not a certification claim, and no archive was built from this head. + +**Round-2 fixes at `55a5c76` (11 of the 13 plugins resubmitted in the deployed batch were rejected):** DashScopeAgent and LangflowAgent 0.2.2 build the optional asset gateway's shared listener and schedule its connection tasks in an explicit empty Context (`create_task(..., context=contextvars.Context())`), so the accept handle no longer retains the first invocation's configuration and revoked authority, and only a validated run token enters a registration's own context; coze/dify/n8n ship the same byte-identical `pkg/asset_gateway.py` and are already certified, so they were deliberately left untouched. WebSearch and URLSummary 0.1.6 gained their own `safe_fetch` module: scheme/host/port validation, refusal of non-public addresses, per-redirect-hop re-validation, connection to the validated IP literal, TLS verification restored (the removed `ssl=False`), raw and inflated byte caps, capped parse input, timeouts, cooperative abort and bounded concurrency in WebSearch. DailyLimitPlugin 0.3.3 and FAQManager 0.1.3 rebuild their admin pages with DOM APIs (no tenant value in an attribute or `innerHTML` sink) and DailyLimitPlugin runs read/modify/serialize/await-persist in one installation-level transaction with explicit rollback. HumanTakeover 0.1.4 re-validates the storage-failure barrier after acquiring the lock (only an explicit reconcile clears it), keys sessions by the trusted bot identity and freezes identity-less legacy rows; ScheNotify 0.2.6 re-enters `bind_invocation(handler, config=…, binding=…)` for detached sends (the pattern GitHubKit and GroupChatSummary passed with), restarts its loop on a worker upgrade, keys reminders by `(bot_uuid, target_type, target_id)` with ownership-checked deletion and keeps failed sends queued. PowerContext 0.1.2 drops the process-environment token fallback; QWeather 0.1.6 cancels and awaits every fan-out task before propagating; GeneralParsers 0.1.11 runs each PDF parse in a dedicated short-lived interpreter process (open → table detection → extraction → close), tears it down before a cancellation propagates, contains dependency crashes and pins `PyMuPDF>=1.24.0,<2.0.0`. Every finding ships a test whose assertion is recorded as failing against the pre-change sources; 22 misc suites pass locally and the Runner isolation harness runs 10 suites. + +**Round-3 fixes at `173d589` (3 of the 11 round-2 resubmissions were rejected again):** HumanTakeover 0.1.5 attributes every console response to the session that requested it (monotonic load sequence plus the key the displayed data belongs to, in-flight responses invalidated and sending locked on a switch, an immutable captured reply target, and the same check on the takeover response and the poll writeback); URLSummary 0.1.7 and WebSearch 0.1.7 give fetch slots a single owner and an idempotent lease (the caller releases a failed submission, the worker releases in its own `finally`, the await is shielded so a queued future is never cancelled by an await-cancellation, and a running worker is never released early), redact userinfo/query/fragment from every error message, exception text and chained traceback, and enforce the absolute deadline and cancellation across WebSearch's whole synchronous lifecycle (DNS on a polled helper thread, deadline-bounded connect, and a watch thread that shuts the socket down so the deferred TLS handshake, status/header parsing and body reads all end). Certification status after this round: 22 of the 25 plugins resubmitted in the last two rounds are approved at their current versions (the 14 from the first batch — DeerFlowAgent, AIImagePlugin, AgenticRAG, AutoTranslate, EssentialCommands, GitHubKit, GoogleSearch, GroupChatSummary, HelloPlugin, KeywordAlert, MCBotPlugin, SysStatPlugin, TavilySearch, WordFSRS — and the 8 from the second — DashScopeAgent, LangflowAgent, DailyLimitPlugin, FAQManager, GeneralParsers, PowerContext, QWeather, ScheNotify), and the three fixed here are awaiting resubmission at 0.1.5 (HumanTakeover) and 0.1.8 (URLSummary and WebSearch are at 0.1.8: after the round-3 fixes, CI exposed that a socket shut down by the abort watch reads as a clean EOF on Linux, so an aborted fetch returned a normal truncated document; the EOF path now re-checks the stop flag and deadline, the post-read path raises `FetchAbortedError`, a short body against the declared `Content-Length` raises `TruncatedResponseError`, every exit path re-checks the abort state, and the tests are platform-independent through a scripted socketpair peer. + +**Round-4 fixes at `447f267`:** the three above were rejected once more and are now at HumanTakeover 0.1.6, URLSummary 0.1.9 and WebSearch 0.1.9. HumanTakeover keeps drafts per session (`openSession` saves the outgoing session's text and staged attachments, bumps a draft generation and restores the target session's) instead of only clearing pending values, attachment reads capture the session key and generation at selection time and are dropped unless both still match, attachments carry an owner and only target-owned ones are posted, and the reply result, draft cleanup and takeover writeback bind to the sending session and generation — closing the reviewer's probe where a late read staged one session's file in another's composer and a reply for one conversation repainted another. URLSummary and WebSearch replace the detached DNS helper thread with a fixed, backpressured resolver pool (four workers, a bounded semaphore over eight outstanding lookups taken non-blockingly at submission, `ResolverBusyError` once exhausted), and the worker releases the slot only after `getaddrinfo` really returns, so a timed-out or cancelled waiter never frees budget for a resolution still running; the reviewer's measurement (twelve timed-out fetches left twelve live resolver threads) now stabilises at four workers with eight in flight and controlled refusals. Both fetcher modules stay byte-identical apart from the docstring. The other 22 plugins of this batch remain approved at their current versions. + +**Round-5 fix at `649170e` (WebSearch 0.1.10):** HumanTakeover 0.1.6 and URLSummary 0.1.9 passed this round; WebSearch was rejected for one remaining hole — the encoded body was never capped and the decoder reused one zlib object while inspecting only `unconsumed_tail`, so data arriving after the first compressed stream ended sat in `unused_data` outside the decoded-size bound (the reviewer's probe returned the body `OK` with 8388608 trailing bytes retained and no size error). The encoded bytes read are now capped cumulatively (decoded cap plus one 64 KiB chunk of slack), exactly one compressed member is supported, and the decoder records the decompression EOF: it refuses to feed an end-of-stream decompressor, rejects trailing bytes that end inside a chunk, and refuses a source exhausted before the stream ends — which is what validates the gzip CRC or zlib checksum. `misc/URLSummary` is deliberately untouched: its certified 0.1.9 carries the same latent hole in its copy of `safe_fetch.py`, so the two modules now diverge by decision, documented in WebSearch's module docstring and `SHARED_RUNTIME.md`; fixing URLSummary would need its own round and a new version. + +**Evidence classes:** The shared-Runner `probe_two_bindings.py` uses a real SDK Worker and synthetic Host/vendor fixture and covers all eight shared Runner agents (coze, dashscope, deerflow, dify, langflow, n8n, tbox, weknora), asserting one object graph, per-binding credentials and per-binding vendor calls; its synthetic artifact digest is not a built archive hash. The KE `shared_subprocess_probe.py` and checked-in JSON evidence use a real SDK child and local Host vector/storage/embedding fixtures; the probe now takes a connector directory too, so all five KnowledgeEngine candidates have real-child two-binding evidence, and `verify_candidates.py` builds and exercises all five archives, LongTermMemory included. LongTermMemory's former in-probe manifest override is no longer the placement difference. These demonstrate only the operations actually invoked, not real vendor/provider execution. RunnerDemo's two-binding proof is in-tree and reproducible now (`RunnerDemo/tests/test_shared_runtime.py`: one real SDK worker, two `InstallationBinding`s, both resolving to the same `PluginContainer`, including through the handler's own slot registry; its identity assertions were shown to fail against a per-binding container mutation using a throwaway harness that is not committed). The earlier-lane archive `f790d29d…` is not in this tree and nothing here is the archive of this integrated PR head. The four-Runner lane does not provide real provider acceptance. Real provider-account invocation, signed/downloaded ZIP identity, independent review, production sandbox/network policy, and two real Cloud Workspace installations sharing the same certified digest remain unproven. External KE connector cancellation races and LongTermMemory's Tool/Command/EventListener write paths are still release gates; do not interpret a successful local fixture or a marketplace badge as production proof. + +No archive was built or published from this integration head. Before any release, build each candidate from the exact committed source and record its immutable archive digest, dependency preparation, certificate fields/signature, downloaded public artifact readback, provider invocation, and two-binding Cloud object/PID/authority evidence separately. No public or production writes were performed by this integration. diff --git a/plugins/SOURCE.json b/plugins/SOURCE.json new file mode 100644 index 000000000..8fc2bbda5 --- /dev/null +++

It does not implement a new RAG backend. Instead, it wraps LangBot's built-in query-scoped knowledge retrieval APIs: + +- `list_pipeline_knowledge_bases()` for enumerating KBs visible to the current query +- `retrieve_knowledge()` for retrieving top-k entries from one or more selected KBs + +The `query_id` is injected by the runtime when the tool is called, then stored inside `QueryBasedAPIProxy`. Because of that, the tool code only needs to pass business parameters such as `kb_id` or `kb_ids`, `query_text`, and `top_k`. + +Although the underlying runtime can support metadata filters, this plugin does not expose raw filters to the agent in the current agentic tool flow. Different knowledge engines and vector backends may use different metadata fields, value formats, and filter semantics, and the agent currently has no reliable schema source for those fields. + +Future versions may expose metadata filtering after the ecosystem has a more unified way to describe filterable fields and operators for each knowledge base. + +## How It Works + +An AgenticRAG request has four main stages: + +### 1. Disable naive retrieval + +During `PromptPreProcessing`, the plugin checks whether the active LLM supports tool calling. + +- if tool calling is supported, it clears the runner's `_knowledge_base_uuids` so the normal naive pre-retrieval step is skipped +- if tool calling is not supported, it keeps naive RAG enabled as a fallback so KB retrieval does not disappear completely + +### 2. Inject retrieval policy into the system prompt + +At the same time, AgenticRAG injects an extra system prompt telling the model that: + +- configured KBs are the primary source of truth for in-scope facts +- there is no automatic retrieval fallback +- for factual, policy, procedural, product, and domain-specific questions, it should prefer `query_knowledge` + +This matters because tool descriptions alone are often not strong enough to reliably change model behavior. + +### 3. Let the model inspect and query KBs + +The agent can then use `query_knowledge` in two steps: + +- `action="list"` to see which KBs are available +- `action="query"` to search one KB or several KBs in parallel + +For single-KB retrieval, the preferred parameter is `kb_id`. +For multi-KB retrieval, use `kb_ids`. + +### 4. Return retrieval results as structured JSON + +The tool merges results, annotates them with `knowledge_base_id`, and returns JSON so the model can continue reasoning, tool use, or final answering. + +## Retrieval Behavior + +When AgenticRAG is enabled, it disables the runner's automatic naive RAG pre-processing for the current pipeline. + +- Retrieval is no longer performed automatically before the model answers +- Whether to query a knowledge base is now a deliberate model decision through `query_knowledge` +- If the model does not call the tool, no KB content will be injected into context + +There is one important exception: + +- if the active LLM does not support tool calling, AgenticRAG keeps naive RAG enabled instead of disabling it + +This reduces unconditional retrieval noise, but it also means prompting matters. The current implementation therefore uses **both**: + +- a tool prompt on `query_knowledge` +- an injected system prompt during `PromptPreProcessing` + +Together, they bias the model toward retrieval for factual, policy, procedural, product, and other domain-specific questions. + +## Why It Is Designed This Way + +This plugin is optimized for a specific tradeoff: + +- keep LangBot's existing KB and retrieval infrastructure +- remove unnecessary always-on retrieval +- let the model make explicit retrieval decisions +- still keep retrieval behavior constrained to the current pipeline + +Compared with naive RAG, this design gives you: + +- less irrelevant context on turns that do not need KB access +- better control over which KB is queried +- room for iterative retrieval, re-querying, and multi-KB reasoning + +The downside is also real: if the model never calls the tool, no KB content appears. That is why the plugin explicitly adds retrieval-oriented prompting, instead of assuming the model will naturally choose retrieval often enough. + +This is also why the plugin now detects tool-call capability before disabling naive RAG. Without that guard, enabling AgenticRAG on a non-tool-capable model would accidentally break KB retrieval entirely. + +## Security Boundary + +This tool is scoped to the current pipeline. + +- LangBot runtime also validates that the requested `kb_id` belongs to the current pipeline before executing retrieval + +This means prompt injection alone should not allow the agent to query arbitrary KBs outside the pipeline configuration. + +## How To Use + +1. Install and enable the plugin. +2. Configure one or more knowledge bases in the current pipeline's local agent settings. +3. Let the agent call `query_knowledge`: + - Start with `action="list"` to inspect available KBs + - Then call `action="query"` with `kb_id` for one KB, or `kb_ids` for multiple KBs queried in parallel + - Provide `query_text`, and optional `top_k` for the merged result count + +## Parameters + +For `action="query"`, the tool currently accepts: + +- `kb_id`: target knowledge base UUID for single-KB retrieval; preferred when querying exactly one KB +- `kb_ids`: optional array of target knowledge base UUIDs for parallel multi-KB retrieval; use only when querying multiple KBs +- `query_text`: retrieval query text +- `top_k`: optional positive integer, default `5`, applied to the merged result set + +If one KB query fails while others succeed, the tool returns a JSON object with `results` and `failed_kbs` so the agent can continue with partial results. + +## Typical Flow + +1.

Permitir que el modelo inspeccione y consulte las bases de conocimiento + +El agente puede usar `query_knowledge` en dos pasos: + +- `action="list"` para ver qué bases de conocimiento están disponibles. +- `action="query"` para buscar en una base de conocimiento o en varias en paralelo. + +Para la recuperación de una sola base de conocimiento, el parámetro preferido es `kb_id`. +Para la recuperación de múltiples bases de conocimiento, use `kb_ids`. + +### 4. Devolver los resultados de la recuperación como JSON estructurado + +La herramienta combina los resultados, los anota con `knowledge_base_id` y devuelve un JSON para que el modelo pueda continuar con el razonamiento, el uso de herramientas o la respuesta final. + +## Comportamiento de recuperación + +Cuando AgenticRAG está habilitado, desactiva el procesamiento previo de RAG ingenuo automático del ejecutor para el flujo actual. + +- La recuperación ya no se realiza automáticamente antes de que el modelo responda. +- La decisión de consultar una base de conocimiento es ahora una decisión deliberada del modelo a través de `query_knowledge`. +- Si el modelo no llama a la herramienta, no se inyectará ningún contenido de la base de conocimiento en el contexto. + +Hay una excepción importante: + +- Si el LLM activo no admite llamadas a herramientas, AgenticRAG mantiene habilitado el RAG ingenuo en lugar de desactivarlo. + +Esto reduce el ruido de recuperación incondicional, pero también significa que el prompting es importante. Por lo tanto, la implementación actual utiliza **ambos**: + +- Un mensaje de herramienta en `query_knowledge`. +- Un mensaje de sistema inyectado durante el `PromptPreProcessing`. + +Juntos, sesgan el modelo hacia la recuperación para preguntas sobre hechos, políticas, procedimientos, productos y otras preguntas específicas del dominio. + +## Por qué está diseñado de esta manera + +Este complemento está optimizado para un compromiso específico: + +- Mantener la infraestructura de base de conocimiento y recuperación existente de LangBot. +- Eliminar la recuperación innecesaria siempre activa. +- Permitir que el modelo tome decisiones de recuperación explícitas. +- Mantener el comportamiento de recuperación restringido al flujo actual. + +En comparación con el RAG ingenuo, este diseño le brinda: + +- Menos contexto irrelevante en los turnos que no necesitan acceso a la base de conocimiento. +- Mejor control sobre qué base de conocimiento se consulta. +- Espacio para la recuperación iterativa, la nueva consulta y el razonamiento sobre múltiples bases de conocimiento. + +La desventaja también es real: si el modelo nunca llama a la herramienta, no aparecerá contenido de la base de conocimiento. Es por eso que el complemento agrega explícitamente mensajes orientados a la recuperación, en lugar de asumir que el modelo elegirá naturalmente la recuperación con la frecuencia suficiente. + +Esta es también la razón por la cual el complemento ahora detecta la capacidad de llamada a herramientas antes de desactivar el RAG ingenuo. Sin esa protección, habilitar AgenticRAG en un modelo sin capacidad de herramientas rompería accidentalmente la recuperación de la base de conocimiento por completo. + +## Límite de seguridad + +Esta herramienta está restringida al flujo actual. + +- El entorno de ejecución de LangBot también valida que el `kb_id` solicitado pertenezca al flujo actual antes de ejecutar la recuperación. + +Esto significa que la inyección de mensajes por sí sola no debería permitir al agente consultar bases de conocimiento arbitrarias fuera de la configuración del flujo. + +## Cómo usar + +1. Instale y habilite el complemento. +2. Configure una o más bases de conocimiento en la configuración del agente local del flujo actual. +3. Deje que el agente llame a `query_knowledge`: + - Comience con `action="list"` para inspeccionar las bases de conocimiento disponibles. + - Luego llame a `action="query"` con `kb_id` para una base de conocimiento, o `kb_ids` para múltiples bases de conocimiento consultadas en paralelo. + - Proporcione `query_text` y un `top_k` opcional para el recuento de resultados combinados. + +## Parámetros + +Para `action="query"`, la herramienta acepta actualmente: + +- `kb_id`: UUID de la base de conocimiento de destino para la recuperación de una sola base de conocimiento; preferido cuando se consulta exactamente una. +- `kb_ids`: matriz opcional de UUID de bases de conocimiento de destino para la recuperación paralela de múltiples bases de conocimiento; utilícelo solo cuando consulte varias. +- `query_text`: texto de la consulta de recuperación. +- `top_k`: entero positivo opcional, por defecto `5`, aplicado al conjunto de resultados combinados. + +Si la consulta de una base de conocimiento falla mientras que otras tienen éxito, la herramienta devuelve un objeto JSON con `results` y `failed_kbs` para que el agente pueda continuar con resultados parciales. + +## Flujo típico + +1. El agente enumera las bases de conocimiento disponibles. +2. El agente selecciona una base de conocimiento o un pequeño conjunto de ellas basándose en el nombre y la descripción. +3. El agente envía una consulta de recuperación enfocada. +4. El agente utiliza los fragmentos devueltos para responder o continuar con el uso de herramientas. + +## Intención del Prompting + +La capa de mensajes está diseñada para comunicar dos cosas al modelo: + +- Estas bases de conocimiento son la fuente autorizada para la información dentro del alcance. +- No existe una recuperación automática de respaldo una vez que AgenticRAG está habilitado. + +Sin esa guía, un LLM puede confiar demasiado en su conocimiento preentrenado y subutilizar la recuperación. La implementación actual, por lo tanto, refuerza la misma política tanto en la capa de mensajes del sistema como en la capa de mensajes de la herramienta. + +## Registros (Logging) + +El complemento ahora emite registros durante la ejecución de la herramienta para que pueda observar cómo el LLM está utilizando AgenticRAG en la práctica. + +Verá registros para: + +- Inicio de la llamada a la herramienta, incluyendo `query_id`, `action` y claves de parámetros. +- Inicio/fin de la enumeración de bases de conocimiento y cuántas son visibles. +- Inicio de la recuperación, incluyendo las bases de conocimiento seleccionadas, `top_k` y una vista previa abreviada de `query_text`. +- Inicio/éxito/falla de recuperación por cada base de conocimiento. +- Resumen final de la recuperación, incluyendo el recuento de resultados combinados, el recuento de bases de conocimiento fallidas y el recuento de resultados devueltos. + +Los mensajes de registro típicos se ven así: + +```text +[AgenticRAG] tool call started: query_id=123 action=query params_keys=['action', 'kb_id', 'query_text', 'top_k'] +[AgenticRAG] retrieval requested: query_id=123 kb_ids=['kb-1'] kb_count=1 top_k=5 query='what is the refund policy' +[AgenticRAG] querying knowledge base: query_id=123 kb_id=kb-1 top_k=5 +[AgenticRAG] knowledge base query succeeded: query_id=123 kb_id=kb-1 result_count=4 +[AgenticRAG] retrieval completed: query_id=123 merged_results=4 failed_kbs=0 +``` diff --git a/plugins/misc/AgenticRAG/readme/README_ja_JP.md b/plugins/misc/AgenticRAG/readme/README_ja_JP.md new file mode 100644 index 000000000..53c66f542 --- /dev/null +++ b/plugins/misc/AgenticRAG/readme/README_ja_JP.md @@ -0,0 +1,142 @@ +# AgenticRAG + +AgenticRAG は、現在の pipeline に設定された知識ベースを Agent から呼び出せるツールとして公開し、利用可能な KB の確認と必要な情報の検索を可能にします。 + +## 役割 + +- `query_knowledge` という 1 つのツールを提供します +- 2 つのアクションをサポートします + - `list`: 現在の pipeline で利用可能な知識ベースを一覧表示 + - `query`: 1 つまたは複数の知識ベースから関連ドキュメントを検索 +- 結果を JSON で返すため、Agent がそのまま後続の推論に利用できます + +## 全体設計 + +AgenticRAG は新しい RAG エンジンではなく、「いつ検索するか」を制御するためのプラグインです。 + +変えているのは検索アルゴリズムそのものではなく、**検索のタイミングを誰が決めるか** です。 + +- runner が毎回自動で検索するのではなく +- モデルが今このターンで検索が必要かを判断し +- 利用可能な KB を確認し +- 1 つまたは複数の KB を明示的に選んで検索する + +この設計は、naive RAG の「毎回先に検索する」方式が持つノイズ、文脈浪費、不必要な断片注入を避けるためのものです。 + +## 実装の仕組み + +このプラグインは新しい RAG バックエンドを実装するものではありません。LangBot にある、`query_id` 単位でスコープされた知識検索 API をツールとして薄くラップしています。 + +- `list_pipeline_knowledge_bases()`：現在の query がアクセス可能な知識ベースを列挙 +- `retrieve_knowledge()`：1 つまたは複数の KB から検索し、統合された top-k 件の結果を取得 + +ツール実行時には runtime が現在の `query_id` を自動で注入します。`QueryBasedAPIProxy` がこの文脈を保持するため、ツール側で明示的に渡す必要があるのは次の項目です。 + +- `kb_id` または `kb_ids` +- `query_text` +- `top_k` + +基盤の runtime 自体は metadata filter を扱えますが、このプラグインでは現時点で Agent フローのツール呼び出しに raw な metadata filter を公開していません。知識エンジンやベクターバックエンドごとに metadata の項目名、型、値の形式、filter の意味が揃っておらず、Agent 側にその schema を安定して渡す仕組みがまだないためです。 + +今後、知識ベースごとに利用可能な filter 項目や演算子を統一的に記述できる仕組みが整えば、metadata filter を Agent に開放することは可能です。 + +## どのように動くか + +AgenticRAG の 1 回の処理は、おおむね 4 段階です。 + +### 1. naive RAG を無効化する + +`PromptPreProcessing` の段階で、plugin は現在の LLM が tool call を使えるかを先に確認します。 + +- tool call を使える場合は runner の `_knowledge_base_uuids` をクリアし、既定の naive RAG 前処理を止めます +- tool call を使えない場合は naive RAG を残し、KB 検索自体が失われないようにします + +### 2. 検索方針を system prompt に注入する + +同時に、追加の system prompt を注入して、モデルに次の点を明示します。 + +- 設定済み KB がその領域の主要な情報源であること +- 自動検索のフォールバックは存在しないこと +- 事実、規則、手順、製品仕様、設定などの質問では `query_knowledge` を優先すべきこと + +これは、tool description だけでは検索行動を十分に安定化できないことが多いためです。 + +### 3. モデルに KB 一覧確認と検索をさせる + +その後、モデルは次の 2 段階で動けます。 + +- `action="list"` で利用可能な KB を確認する +- `action="query"` で 1 つまたは複数の KB を検索する + +単一 KB の場合は `kb_id`、複数 KB を並列検索する場合のみ `kb_ids` を使います。 + +### 4. 結果を構造化 JSON で返す + +ツールは結果をマージし、`knowledge_base_id` などを補った JSON を返します。これによりモデルはそのまま推論を継続できます。 + +## セキュリティ + +このツールは、現在の pipeline に設定された知識ベースだけを対象にします。 + +- LangBot runtime 側でも、`kb_id` が現在の pipeline に属しているか再検証します + +そのため、prompt injection だけで pipeline 外の任意の KB を検索することは想定されていません。 + +## 使い方 + +1. このプラグインをインストールして有効化します。 +2. 現在の pipeline の local agent 設定で、1 つ以上の知識ベースを関連付けます。 +3.

The stored row is overwritten whole, so an unlocked + writer could commit a snapshot that a concurrent writer had already moved past + and roll the newer state back when the two Host writes complete out of call + order. `snapshot()` reads under the same lock. +- If a mutation or its write fails, or the call is cancelled, the in-memory state + is restored to the last snapshot that actually landed, so memory and the durable + row do not diverge.

Dedicated workers keep reading the legacy key unchanged. +- The per-installation cache is unbounded in size until revocation; the runtime + revokes on uninstall, disable, Workspace removal and upgrade. +- Revocation is serialized per installation but may overlap with sibling + installations' invocations; per-installation state is locked, cross-installation + state is not shared. + +## Tests + +`tests/test_installation_scoped_daily_limit.py` drives two distinct +`InstallationBinding`s (same instance and Workspace, different installation +uuids) through one plugin object with the installed SDK's `bind_invocation`, over +a synthetic Host KV whose row key mirrors LangBot's.

A route that does not carry the + installation binding therefore cannot work under shared placement. +- Legacy data migration is not performed: on shared placement a pre-existing + shared `faq_entries` row is no longer read (each installation starts empty). + Dedicated workers keep reading the legacy key unchanged. +- The entries list handed to a Page response is the live cached list; it is not + copied, so a concurrent writer for the same installation can change it while a + response is being serialized. +- The per-installation cache is unbounded in size until revocation; the runtime + revokes on uninstall, disable, Workspace removal and upgrade. +- Revocation is serialized per installation but may overlap with sibling + installations' invocations; per-installation state is locked, cross-installation + state is not shared. + +## Tests + +`tests/test_installation_scoped_faq.py` drives two distinct +`InstallationBinding`s (same instance and Workspace, different installation +uuids) through one plugin object with the installed SDK's `bind_invocation`, over +a synthetic Host KV whose row key mirrors LangBot's.

A hard timeout + (`DEFAULT_TIMEOUT_SECONDS`, 300 s), a cancellation or a crash terminates and reaps the + worker before the caller resumes, so no dependency work can keep running into a later + request. PyMuPDF module state only ever exists inside the per-parse worker; the shared + process never imports it. +- Supported dependency range: `PyMuPDF>=1.24.0,<2.0.0` (see `requirements.txt`). The + process boundary is what makes the shared runtime safe on this whole range; the range is + bounded to the 1.x line this implementation is verified against. + +## Page scoping + +`PageRequest` carries no binding. `ParserObservabilityPage` resolves the current +installation from the task-local SDK binding (`self.get_installation_binding()`), which the +Host sets from the page request's installation context. `/snapshot` and `/clear` therefore +act only on the calling installation's store and never expose another installation's +filenames or errors. When no binding is active (direct, non-invocation use; unit tests) an +isolated "unscoped" store is used — it never receives records from a bound invocation. + +## Known limits + +- Telemetry is in-memory, per worker.

Pollers are keyed by installation binding and stopped by `on_installation_revoked`. +- Deduplicates with `last_event_id`, pushing only events newer than the last seen; on first subscription it records the current cursor and never backfills history. +- Subscriptions (including `bot_uuid` + chat target) are persisted in the plugin KV store, so push continues after a restart. + +## Configuration + +- `language` (default `zh_Hans`): language for all bot messages and event-push notifications — `en_US` or `zh_Hans`. +- `github_token`: GitHub personal access token. **Strongly recommended** — raises the rate limit from 60/hr to 5000/hr (required for event polling) and enables private repos. +- `poll_interval` (default 120, min 60): poll interval in seconds. GitHub caches the events feed ~60s, so lower values don't help. +- `max_events_per_push` (default 5): max events per repo per push, to avoid flooding after downtime. + +## Rate limit note + +Without a token the anonymous quota is only 60 requests/hour, which a few subscribed repos will exhaust quickly. Always configure a token for production use. + +## Shared runtime + +`manifest.yaml` declares `sharedRuntime: shared-runtime-v1` + +`componentModel: stateless-v1`, so this plugin can be placed on a multi-tenant +shared worker: config is read per invocation, subscriptions are namespaced per +installation, and each installation's poller is stopped in +`on_installation_revoked`.

Select a conversation, click **Take Over** to block the AI, then reply manually. +4. Click the avatar to inspect user/group info; use **Clear Storage** to reset data. + +## Storage and upgrades + +Each session's metadata and history are now saved together under a separate +`ht_session_v2_` key. Updating one conversation no longer rewrites every +conversation's history. Writes are serialized in the plugin process and storage +failures are returned to callers rather than reported as successful saves. + +On first startup, the plugin reads the legacy `ht_sessions` / `ht_messages` +snapshots and copies **all** their records into the new format, without applying +retention during migration. A completion marker is written only after every +session has been saved. Interrupted migrations can be retried. The original keys +remain as an untouched migration-time backup; they are not updated afterward. +Subsequent startups read only the new records. Back up plugin storage before +upgrading: **downgrading does not include conversations changed after migration**. +The console's Clear storage action removes both formats and their history, and +discards any unsent draft. + +A session record is limited to **8 MiB of UTF-8 JSON**, leaving room for SDK +base64 encoding within the 16 MiB transport frame. Exceeding this limit raises an +explicit error before sending the storage request; it does not trim message +content or discard previously saved history. New messages still use the existing +300-message retention policy. A failed save restores the last acknowledged cache; +this is not evidence that a remotely dispatched write was rejected. +A legacy session exceeding the limit stops initialization and leaves the original +snapshots intact; it requires export/recovery rather than automatic truncation. +A legacy aggregate already too large to read through the SDK also requires +out-of-band recovery. Failed initialization never falls back to empty storage. + +This is single-plugin-process serialization, not a multi-writer transaction. +Clear storage deletes multiple keys and may partially complete on a storage +failure. Caller cancellation (including repeated cancellation) waits for the +shielded update, clear, or migration to settle before releasing serialization. +An acknowledged commit remains in the cache even if its caller was cancelled. + +Any remote mutation error, including a timeout or lost connection, has an unknown +commit outcome: it marks storage uninitialized and blocks further writes, clear, +and ordinary reinitialization. Do not assume the write was rejected or retry it. +The barrier is re-checked after the installation lock is acquired, so a caller that +was already queued for that lock when the failure happened is blocked too and +cannot write over the unknown outcome. An operator must first establish that the +old host operations have finished (or stop the old host writer), reconcile +persisted data, then reload using `await plugin.reconcile()` or restart the plugin; +that explicit recovery path is the only one that lifts the barrier. A mere read, +an ordinary load, or plugin restart while old host requests can still commit is +**not** safe reconciliation. Partial clear/migration can then be retried. +If a manual reply was delivered but saving its +history failed, the console explicitly warns **not to resend** it. + +## Session identity + +A session key is `:_`: the trusted bot uuid +resolved from the event query is part of the key, so one installation that serves +several bots/adapters keeps separate history, takeover state and reply targets per +bot - two bots with the same group/user id no longer share one record. An event +whose bot identity cannot be resolved is not recorded at all, and a session record +rejects a different bot's or adapter's identity, so a foreign event cannot rewrite +the reply target of an existing session. + +Rows written before session keys carried the bot identity keep their old key and +are left untouched: an unscoped key may already contain two bots' history, so it is +never migrated or merged into a bot-scoped session. They stay readable, are never +written by another bot's events (new messages always use a bot-scoped key), and +remain replyable only while their stored bot uuid is known. The console may list +such a row next to the bot-scoped session that continues the same conversation. + +### Storage regression tests + +With the shared-runtime SDK (`langbot-plugin`) installed, run from `HumanTakeover/`: + +```sh +python -m pytest tests -q +``` + +Tests cover migration/readback, bounded per-session writes, concurrent updates, +failure-barrier handling, rollback/error reporting, bot-identity scoping, +retention and clearing. The stdio test uses the real SDK and an OS subprocess, +with a synthetic Host KV sink; it is not a full LangBot deployment or a live +database test, and it needs a host that can spawn that child process (it fails on +Windows with `WinError 10106`). + +## Components + +- **EventListener**: records messages, caches the adapter, matches trigger words, and blocks the AI while taken over. +- **Page (`console`)**: the Web management console (`index.html` + `console.py`). + +## Shared runtime + +`manifest.yaml` declares `sharedRuntime: shared-runtime-v1` + +`componentModel: stateless-v1`, so this plugin can be placed on a multi-tenant +shared worker: config is read per invocation, sessions/history/storage keys are +scoped to the installation binding and loaded on demand, and +`on_installation_revoked` drops a revoked installation's cache.
