- Replace legacy pipeline binding card + RoutingRulesEditor with unified
EventBindingsEditor; remove use_pipeline_uuid/pipeline_routing_rules
from bot form schema and API update handler
- Add _augment_event_data() to botmgr for filter virtual fields
(message_text, message_element_types, chat_type)
- Add alembic migration 0009: migrate use_pipeline_uuid and
pipeline_routing_rules into event_bindings on first run
- Fix command.tsx: data-[disabled] -> data-[disabled=true] so cmdk 1.x
items (data-disabled=false) are not pointer-events:none
- EventBindingsEditor: onSelect on CommandItems, filter conditions panel,
disabled bindings section, dnd reorder
- i18n: add filter/condition keys for zh-Hans and en-US
- Update tests to match new bot service behavior

CI follow-up to the local/remote MCP work:
- Apply ruff format to provider/tools/loaders/mcp.py and the 0006
normalize-remote-mode migration (Lint job failed on formatting).
- test_migrations.py hardcoded the head revision as 0005_*, which broke
once 0006 landed. Resolve the actual head from the Alembic
ScriptDirectory so future migrations don't require editing the test.
Replace the three-way transport choice (stdio / sse / httpstream) for
connecting LangBot to external MCP servers with two modes: local (stdio)
and remote. Remote servers only require a URL; the runtime auto-detects
the transport (tries Streamable HTTP, falls back to SSE).
- provider/tools/loaders/mcp.py: add _init_remote_server() with
Streamable-HTTP-then-SSE probing; dispatch 'remote' lifecycle, keep
legacy sse/http branches for back-compat
- plugin/connector.py: normalize legacy http/sse marketplace modes to
'remote' on Space install, preserving connection params
- entity/persistence/mcp.py: document mode as stdio, remote (legacy: sse, http)
- alembic 0006: idempotent data migration mapping existing sse/http rows
to remote (downgrade maps back to http)
- api/http/service/mcp.py: stash runtime_info (status + tool list) into
test task metadata before tearing down the temp session
- web: collapse mode dropdown to local/remote, remote renders URL+timeout
only, edit auto-maps legacy sse/http to remote; show tools after test in
create mode from task metadata; remove dead plugins/mcp-server/ tree
- i18n: local/remote labels + mode/url hints across 8 locales
The legacy pkg/persistence/migrations (DBMigration / dbmXXX) system now
coexists with Alembic but accepts no new migrations — all new schema
changes go through Alembic.
- remove dbm026_llm_model_context_length (superseded by Alembic
0005_add_llm_context_length, which makes the identical change)
- cap required_database_version at 25 (legacy chain dbm001-025 kept
read-only to upgrade pre-existing 3.x DBs to the Alembic baseline)
- add migrations/README.md documenting the freeze
- document the Alembic-only policy and revision-id/idempotency rules in
AGENTS.md
* refactor(provider): use LiteLLM as unified LLM requester backend
- Replace 23+ individual requester implementations with unified litellmchat.py
- Add litellm_provider field to 27 YAML manifests for provider routing
- Delete redundant requester subclasses
- Add unit tests for LiteLLMRequester (29 tests)
- Fix num_retries parameter name (was max_retries)
- Fix exception handling order for subclass exceptions
LiteLLM provides unified API for 100+ providers, eliminating need for
provider-specific requesters.
* fix: ruff format provider.py
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* refactor(provider): simplify LiteLLM requester usage handling
- Remove unused Anthropic-specific tool schema generation
- Share completion argument construction between normal and streaming calls
- Use LiteLLM/OpenAI native usage fields for monitoring
- Collect stream token usage from LiteLLM stream_options
- Update LiteLLM requester tests for unified usage fields
* restore: restore deleted provider requester files
Restore individual provider requester implementations that were
removed in de61b5d3. These files coexist with the unified
litellmchat.py backend.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* feat: update requesters and improve provider selection UI
- Added `litellm_provider` field to various requesters' YAML configurations.
- Removed obsolete Python requester files for OpenRouter, PPIO, QHAIGC, ShengSuanYun, SiliconFlow, Space, TokenPony, VolcArk, and Xai.
- Introduced new requesters for Tencent and Together AI with corresponding YAML configurations and SVG icons.
- Enhanced the ProviderForm component to include a searchable dropdown for selecting providers, improving user experience.
- Updated localization files to include search provider text for both English and Chinese.
* fix(provider): align litellm rebase with master
* fix(provider): capture streaming token usage; add token observability
The LiteLLM streaming requester only captured usage when a chunk had an
empty `choices` list. Many OpenAI-compatible gateways (e.g. new-api) and
providers send the final usage payload in a chunk that still carries an
empty-delta choice, so streamed calls always recorded 0 tokens in the
monitoring logs/dashboard (non-streaming worked).
- Capture stream usage whenever a chunk carries it, regardless of choices
- Add robust _normalize_usage (dict/obj shapes, derive missing total_tokens)
- Register litellm in bootutils/deps.py (was in pyproject only)
- Add MonitoringService.get_token_statistics + /monitoring/token-statistics
endpoint: summary, per-model breakdown, token timeseries, and a
zero-token-success data-quality signal
- Add TokenMonitoring dashboard tab (summary tiles, stacked token chart,
per-model table) + i18n (en/zh)
- Regression tests for stream usage capture and usage normalization
Verified end-to-end against a real OpenAI-compatible endpoint with
gpt-5.5 and claude-opus-4-8: tokens now recorded non-zero for both
streaming and non-streaming paths.
* refactor(provider): simplify litellm capabilities
* style: simplify wrapped expressions
* feat(models): persist context metadata
* fix(provider): handle dict embeddings and openai-compatible rerank in LiteLLMRequester
- invoke_embedding: support both object- and dict-shaped response.data
entries (OpenAI-compatible gateways like new-api return dicts)
- invoke_rerank: litellm.arerank rejects the 'openai' provider, so for
openai-compatible (or unspecified) providers call the standard
Jina/Cohere-style POST /v1/rerank endpoint directly over HTTP
- accept both 'relevance_score' and 'score' fields in rerank results
- add unit tests for the openai-compatible HTTP rerank path
* feat(provider): enforce requester support_type when adding models
- frontend: AddModelPopover only shows model-type tabs (llm/embedding/
rerank) that the provider's requester declares in its manifest
support_type; ModelsDialog fetches requester manifests and maps
requester -> support_type, passed down through ProviderCard
- backend: add _validate_provider_supports guard in create_llm_model /
create_embedding_model / create_rerank_model so a model cannot be
attached to a provider whose requester does not support that type,
even if the frontend restriction is bypassed (manifests without
support_type are allowed for backward compatibility)
- manifests: correct support_type for providers that do not offer all
three model types:
- llm only: anthropic, deepseek, groq, moonshot, openrouter, xai
- llm + text-embedding: openai, gemini, mistral
- add rerank to new-api (verified working via /v1/rerank)
- set llm + text-embedding + rerank for aggregator/unknown gateways
* feat(provider): add searchable alias to requester manifests
- add a free-text 'alias' field to every requester manifest spec,
containing the vendor's English/Chinese names, pinyin, common
nicknames and flagship model-series names (e.g. moonshot -> kimi,
月之暗面; zhipu -> glm, 智谱清言)
- frontend: ProviderForm requester search now also matches against
alias (substring/contains), so searching 'kimi' surfaces Moonshot,
'硅基' surfaces SiliconFlow, etc.
- also fix support_type: openrouter (relay) supports embedding+rerank;
LangBot Space gains rerank (coming soon)
* fix(provider): make support_type guard defensive against incomplete model_mgr
- _validate_provider_supports now uses getattr to gracefully skip when
model_mgr / provider_dict / manifest lookup is unavailable, instead of
raising AttributeError (fixes unit tests that mock ap.model_mgr as a
bare SimpleNamespace)
- add TestValidateProviderSupports covering: allow supported type,
reject unsupported type, allow when support_type missing, allow when
provider unknown, degrade safely when model_mgr is incomplete
* fix(persistence): guard 0004 migration against missing llm_models table
The 0004_add_llm_model_context_length migration called
inspector.get_columns('llm_models') unconditionally, raising
NoSuchTableError when the table does not exist (e.g. migrating a
fresh/empty DB, as exercised by the integration tests where
create_all() registers no tables because the ORM models are not
imported). Every other migration guards with a table-existence check
first; add the same guard here for both upgrade and downgrade.
Also restore the test head assertion to 0004 (it had been lowered to
0003 to mask this failure).
* Merge branch 'master' into feat/litellm
Resolve conflicts:
- uv.lock: regenerated via 'uv lock' to reconcile litellm/fastuuid
(ours) with openai bump (master).
- Alembic migrations: master added 0004_add_mcp_readme while this
branch added 0004_add_llm_model_context_length, both as children of
0003 (would create multiple heads). Re-chain the litellm migration as
0005_add_llm_model_context_length with down_revision=0004_add_mcp_readme
for a single linear head. Update test head assertion accordingly.
* fix(persistence): shorten migration revision id to fit varchar(32)
PostgreSQL stores alembic_version.version_num as varchar(32).
'0005_add_llm_model_context_length' (33 chars) overflowed it, raising
StringDataRightTruncationError in the PG migration tests. Rename the
revision (and file) to '0005_add_llm_context_length' (27 chars) and
update the head assertions in both SQLite and PostgreSQL migration
tests.

Capture the README markdown from LangBot Space when installing an MCP
server and store it on the mcp_servers record (new readme column +
alembic migration 0004). The detail page can then render docs offline,
independent of the server's runtime/connection state.
Migration 0003 failed when rerank_models table already exists from create_all().
Add table existence check to prevent duplicate creation error in CI environments with cached database.
* feat(provider): add rerank model management as a core model type
* feat(provider): add rerank support to existing requesters and new rerank providers
* feat(web): add rerank model management UI and pipeline config
* fix(provider): correct rerank support_type after verification
- Add rerank to OpenRouter (confirmed /api/v1/rerank endpoint)
- Remove rerank from Ollama (no native support, PR #7219 unmerged)
- Remove rerank from JiekouAI (no rerank docs found, URL path mismatch)
* fix(provider): remove alru_cache from model getters and add rerank param hints
* fix: resolve lint errors
- Remove unused alru_cache import from modelmgr.py
- Remove unused error_message variable in invoke_rerank

- Create programmatic alembic env (no CLI/alembic.ini needed)
- Support async engines via run_sync passthrough
- render_as_batch=True for SQLite ALTER TABLE compatibility
- Auto-stamp baseline on first run (existing DB at version 25)
- Run alembic upgrade head after legacy migrations
- Include sample migration showing schema + data migration patterns
- Add alembic dir to package-data for distribution
* refactor: pipeline routing rules - add routed_by_rule bypass and diagnostic logging
- Add routing rules editor (RoutingRulesEditor component)
- Add routed_by_rule bypass logic in response rules
- Add diagnostic logging for pipeline routing
- Database migration for bot pipeline routing rules
- Extract RoutingRulesEditor component from BotForm
- Revert log levels to debug
* feat: add message_has_element routing rule type
Support routing by message element type (Image, Voice, File, Forward,
Face, At, AtAll, Quote) with eq/neq operators.
* test: add unit tests for pipeline routing rules
20 tests covering _match_operator (eq/neq/contains/not_contains/
starts_with/regex/invalid) and resolve_pipeline_uuid (launcher_type/
launcher_id/message_content/message_has_element/first-match-wins/
skip-invalid/default-operator).
* fix(web): add missing 'message_has_element' to routing rule type validation
The Zod schema and TypeScript type for PipelineRoutingRule.type were
missing the 'message_has_element' variant, causing silent form validation
failure when saving routing rules with this type.
* feat: add pipeline discard functionality and localization support
* feat(web): improve drag-and-drop with DragOverlay, add discard monitoring and pipeline icons
- Add DragOverlay for smooth cursor-following drag in routing rules editor
- Remove transition to eliminate redundant swap animation on drop
- Record discarded messages in monitoring system via _record_discarded_message
- Display pipeline name (Workflow icon) and runner name (Play icon) on session monitor messages
- Show discard badge on discarded messages in session monitor
- Add i18n translations for discarded/userMessage/botMessage
* fix: ensure discarded messages appear in session monitor and improve icons
- Create/update monitoring session for discarded messages so they show in
the bot session monitor (was only inserting message rows, not sessions)
- Use human-readable 'Discarded' as pipeline_name instead of '__discard__'
- Change runner icon from Play to Bot for better AI Agent semantics
* fix: merge discarded messages into same session and remove session-level pipeline name
- Use LauncherTypes enum for session_id in discarded messages to match
the format used by monitoring_helper (fixes duplicate sessions)
- Don't overwrite session pipeline info on discard — a session can have
messages from multiple pipelines
- Remove pipeline_name from session list and chat header since it's
now shown per-message and a session is no longer single-pipeline
* fix(web): only show save button on config tab in bot detail page
* fix(web): scroll to bottom after messages render in session monitor

* feat(web): add onboarding wizard for guided bot creation
Implement a full-screen 4-step wizard at /wizard that guides users
through selecting a platform, configuring a bot, choosing an AI engine,
and completing setup. The wizard uses DynamicFormComponent for adapter
and pipeline configuration, embeds BotLogListComponent for real-time
debugging, persists state to localStorage, and integrates with Space
OAuth flow. Also fixes a prompt-editor crash in DynamicFormComponent
when value is undefined.
* feat(wizard): redesign step 0/1 flow, add skip dialog, auto-expand log images
- Step 0: Remove bot name/description fields; auto-derive name from adapter
label; create disabled bot on confirm; advance to Step 1 automatically
- Step 1: Replace 'Create Bot' with 'Save & Enable Bot'; update adapter
config and enable bot; disable form fields after saving
- Add skip confirmation AlertDialog with i18n message
- Add LanguageSelector to wizard header
- Move wizard sidebar entry to last position to prevent fallback redirect loop
- Add defaultExpanded prop to BotLogCard; auto-expand entries with images
in wizard via autoExpandImages prop on BotLogListComponent
- Remove automatic default pipeline creation (write_default_pipeline) from
backend persistence manager since the wizard now handles pipeline creation
- Update all 4 locale files (en-US, zh-Hans, zh-Hant, ja-JP)
* fix(wizard): hide detailed logs link in wizard, allow re-editing bot config after save
- Add hideDetailedLogsLink prop to BotLogListComponent; pass it in wizard
- Remove isEditing on DynamicFormComponent so form stays editable after save
- Always show save button; label changes to 'Re-save' after first save
- Add resaveBot i18n key to all 4 locale files
* style(wizard): move save button into config card header
* fix(wizard): initialize userInfo/systemInfo so model selector works
The wizard runs outside /home layout, so userInfo was null. This caused
the model-fallback-selector to filter out all Space models, showing an
empty dropdown. Fix by calling initializeUserInfo() and
initializeSystemInfo() before fetching wizard data.
Also:
- Hide log toolbar in wizard via hideToolbar prop on BotLogListComponent
- Add empty state message for bot logs (noLogs i18n key, all 4 locales)
* feat(wizard): redesign AI Engine step with left-right split layout
Before selecting a runner: centered grid of runner cards.
After selecting: left panel shows compact runner list for switching,
right panel shows runner config form with slide-in animations.
Also fix prompt field default: add default value to prompt-editor field
in ai.yaml metadata so the prompt is pre-populated with
'You are a helpful assistant.' instead of being empty.
* feat(pipeline): add default values to ai.yaml runner configs and show_if for n8n auth fields
- Sync default values from default-pipeline-config.json to all runner
config fields in ai.yaml so wizard forms are pre-populated
- Add show_if conditions to n8n-service-api auth fields so only the
relevant credentials appear based on selected auth-type
- Fix prompt-editor crash in DynamicFormItemComponent when field.value
is undefined (Array.isArray guard + fallback)
- Improve wizard Step 2 split layout with fixed column widths,
independent scroll, ring clipping fix, and mobile responsiveness
- Use key={selected} on DynamicFormComponent to force remount on
runner switch
- Improve pipeline creation flow: create → fetch defaults → merge AI
section → update (preserves trigger/safety/output defaults)
* feat(dynamic-form): add systemContext prop with __system.* namespace for show_if conditions
- Add systemContext prop to DynamicFormComponent for injecting external
variables accessible via __system.* prefix in show_if conditions
- Extract resolveShowIfValue() helper for cleaner field resolution
- Pass { is_wizard: true } from wizard to hide knowledge-bases field
- Remove bot config save toast in wizard (keep inline indicator)
* feat(sidebar): render wizard as standalone item before Home group with fallback redirect fix
* fix(wizard): remove unused setBotDescription to fix lint error
* feat: Implement WebSocket long connection client for WeChat Work AI Bot
- Added WecomBotWsClient to handle WebSocket connections for receiving messages and sending replies.
- Introduced a new migration (dbm022) to add 'enable-webhook' field to existing wecombot adapter configs, ensuring backward compatibility.
- Updated WecomBotAdapter to support both WebSocket and webhook modes based on the new configuration.
- Enhanced YAML configuration for WecomBot to include 'enable-webhook' and 'Secret' fields, adjusting requirements accordingly.
- Incremented database version to 22 to reflect schema changes.
* fix:db enable-webhook is false
* fix:add logic
* fix:Removed an unnecessary configuration check
* fix: migration
* fix: update migration
* fix:migration
