- If you changed the definition of database entities, please update the migration file in `src/langbot/pkg/persistence/migrations/` and update the constants.py file in `src/langbot/pkg/utils/constants.py` with the new migration number.
+- LangBot uses [Alembic](https://alembic.sqlalchemy.org/) to manage database migrations, supporting both SQLite and PostgreSQL. Migration files are located in `src/langbot/pkg/persistence/alembic/versions/`. If you changed the definition of database entities (ORM models), generate a new migration script by running `uv run python -m langbot.pkg.persistence.alembic_runner autogenerate "description of your change"` in the project root (requires `data/config.yaml` to exist). Review and edit the generated script before committing. Migrations are executed automatically on LangBot startup. For data migrations (e.g. modifying JSON field content), you need to manually add the migration code in the generated script.

+# Agent-owned Context 协议设计
+
+本文档描述插件化 AgentRunner 场景下的上下文边界。结论先行：LangBot 不应成为最终 agentic context manager；LangBot 应提供 context substrate，AgentRunner 或其背后的 agent runtime 自己决定如何管理历史、压缩、召回和 KV cache。
+
+## 当前状态
+
+**当前分支已落地**：
+
+- ✅ `AgentRunContext` — event-first context 模型
+- ✅ `ContextAccess` — cursor、inline policy、available APIs
+- ✅ `AgentRunAPIProxy.history` — page/search API
+- ✅ `AgentRunAPIProxy.events` — get/page API
+- ✅ `AgentRunAPIProxy.artifacts` — metadata/read_range API
+- ✅ `AgentRunAPIProxy.state` — get/set/delete API
+- ✅ EventLog / Transcript / ArtifactStore — host 事实源
+- ✅ PersistentStateStore — 持久化状态存储
+- ✅ `max-round` 已从协议实体中移除；如某 runner 仍需要类似历史窗口参数，应作为 runner binding config 由插件 manifest 暴露，而不是 Host / Pipeline 协议字段
+- ✅ 外部 harness context projection 已用 Claude Code runner 做 MVP 验证：context 文件、skill 投影、MCP 配置和 host-owned resume state
+
+## 1. 设计原则
+
+### 1.1 Agent 拥有上下文策略
+
+不同 runner 背后的 runtime 差异很大：
+
+- 官方 local-agent 可能依赖 LangBot 的模型、工具、知识库和存储。
+- Claude Code SDK / Codex 类 runtime 可能有自己的 session、transcript、tool loop 和上下文压缩。
+- Pi Agent SDK 或外部 agent 平台可能只需要当前事件和一个外部 conversation key。
+
+因此 LangBot 不应强行决定最终传给模型的历史窗口。Host 只提供：
+
+- 当前事件的完整结构化信息。
+- 稳定身份和会话引用。
+- 可授权读取的 history / event / artifact / state API。
+- 可投影给外部 harness 的 scoped context、MCP、skill 和 resource refs。
+- payload hard cap 和权限 guardrail。
+
+### 1.2 不再把 `max-round` 作为目标设计
+
+`max-round` 这类历史窗口参数不应继续作为 AgentRunner 协议或 Pipeline adapter 的核心概念。
+
+如果某个 runner 仍需要“最多读取多少轮历史”这样的策略参数，应由该 runner 在自己的 manifest/config schema 中声明，并作为 binding config 存到 `ctx.config` / `runner_config`。Host 只提供 history pull API、cursor、hard cap 和权限边界；runner 自己决定是否读取、读取多少、如何截断和压缩。
+
+当前 official local-agent 方向是通过 Host history API 拉取 transcript，并由 runner 自己管理模型上下文。它不依赖 Pipeline adapter 下发的 `max-round` / bootstrap 窗口。
+
+新协议不应该问“LangBot 每轮裁几轮历史给 agent”，而应该问：
+
+- 这类 runner 是否自管 context？
+- 事件到来时 host 应 inline 哪些最小信息？
+- agent 需要更多上下文时通过什么 API 拉取？
+- host 如何保证安全、可审计和可分页？
+
+### 1.3 Host 保存事实源，Agent 管理 working context
+
+三类数据要分开：
+
+- `EventLog`: Host 保存原始事件、工具调用、投递结果、错误和系统事件。
+- `Transcript`: Host 从 EventLog 投影出的对话视图，用于 UI、审计和按需历史读取。
+- `Working context`: Agent 本轮实际送进模型或 runtime 的上下文，由 AgentRunner 决定。
+
+LangBot 可以为简单 runner 提供 bootstrap window，但这只是 convenience，不是主架构。
+
+## 2. Event 到来时传什么
+
+默认 `AgentRunContext` 应尽量小且稳定：
+
+```python
+class AgentRunContext(BaseModel):
+    run_id: str
+    trigger: AgentTrigger
+    event: AgentEventContext
+    conversation: ConversationContext | None
+    actor: ActorContext | None
+    subject: SubjectContext | None
+    input: AgentInput
+    delivery: DeliveryContext
+    resources: AgentResources
+    context: ContextAccess
+    state: AgentRunState
+    runtime: AgentRuntimeContext
+    config: dict[str, Any]
+```
+
+默认规则：
+
+- Host MUST NOT inline full history by default.
+- Host SHOULD inline only current event / input and context handles.
+- Runner owns working-context assembly.
+- Runner MAY use Host history / event / artifact / state / storage APIs when authorized.
+- Official runners MUST consume Host infrastructure through the same public APIs as third-party runners.
+
+### 2.1 必须 inline 的内容
+
+每次 run 必须 inline：
+
+- 当前 event 的稳定类型、id、时间、source。
+- 当前输入文本和结构化内容。
+- 附件 / 文件 / 图片的 metadata 和 artifact ref。
+- actor、subject、conversation、thread、bot、workspace。
+- delivery 能力，例如是否支持 streaming、reply target、平台限制。
+- 已授权资源列表。
+- context cursors 和可用 API 能力。
+- runner binding config。
+
+这些是 agent 决定下一步需要的最低信息。
+
+### 2.2 默认不 inline 的内容
+
+默认不要 inline：
+
+- 完整历史消息。
+- 大文件全文。
+- 大工具结果。
+- 全量知识库内容。
+- 平台原始 payload 大对象。
+- 每轮重新生成的大段 summary。
+
+这些会破坏跨进程序列化成本、泄露范围、KV cache 稳定性，也会迫使 host 替 agent 做 context 策略。
+
+### 2.3 可选 bootstrap
+
+根据 runner manifest 可以提供可选 bootstrap：
+
+```yaml
+context:
+  bootstrap: none | current_event | recent_tail | summary_tail
+  max_inline_events: 0
+  max_inline_bytes: 0
+```
+
+建议默认：
+
+- 自管 runtime：`bootstrap: current_event`
+- 简单 HTTP runner：`bootstrap: recent_tail`
+- runner 如果需要 `recent_tail` 策略，应通过自己的 binding config 声明窗口大小；Host 不把 `max-round` 作为通用协议字段扩展。
+
+## 3. ContextAccess
+
+`ContextAccess` 是 host 交给 agent 的上下文读取入口描述：
+
+```python
+class ContextAccess(BaseModel):
+    conversation_id: str | None
+    thread_id: str | None
+    latest_cursor: str | None
+    event_seq: int | None
+    transcript_seq: int | None
+    has_history_before: bool
+    inline_policy: InlineContextPolicy
+    available_apis: ContextAPICapabilities
+```
+
+它告诉 agent：
+
+- 当前事件位于哪条 conversation / thread。
+- 若需要更多历史，从哪个 cursor 开始拉。
+- host inline 了什么，没 inline 什么。
+- 当前 run 有哪些 context API 权限。
+
+## 4. Agent 如何获取更多上下文
+
+所有 API 都必须走 `AgentRunAPIProxy`，并由 host 用 `run_id` 校验。
+
+### 4.1 History API
+
+```python
+await api.history.page(
+    conversation_id=ctx.context.conversation_id,
+    before_cursor=ctx.context.latest_cursor,
+    limit=50,
+    direction="backward",
+    include_artifacts=False,
+)
+```
+
+返回：
+
+```python
+class HistoryPage(BaseModel):
+    items: list[TranscriptItem]
+    next_cursor: str | None
+    prev_cursor: str | None
+    has_more: bool
+```
+
+约束：
+
+- `limit` 有 host hard cap。
+- 默认只能读当前 conversation / thread。
+- 跨会话读取必须有 manifest permission + binding policy。
+- 返回 artifact ref，不默认返回大文件内容。
+
+### 4.2 Search API
+
+```python
+await api.history.search(
+    query="用户之前提到的数据库连接信息",
+    filters={
+        "conversation_id": ctx.context.conversation_id,
+        "event_types": ["message.received"],
+    },
+    top_k=10,
+)
+```
+
+Search 可以先用数据库全文索引，后续再接 embedding recall。它是 host 提供的检索能力，不等于 agent 的长期记忆策略。
+
+### 4.3 Event API
+
+```python
+await api.events.get(event_id)
+await api.events.page(before_cursor=..., limit=...)
+```
+
+Event API 用于读取非消息事件、工具事件、系统事件。Agent 不应把所有事件都当成 user/assistant message。
+
+### 4.4 Artifact API
+
+```python
+await api.artifacts.metadata(artifact_id)
+await api.artifacts.read_range(artifact_id, offset=0, length=65536)
+await api.artifacts.open_stream(artifact_id)
+```
+
+约束：
+
+- 校验 artifact 所属 conversation / run / binding。
+- 校验 MIME、大小、过期时间和权限。
+- 大文件按 range/stream 读取。
+- 工具大结果也应 artifact 化。
+
+### 4.5 State API
+
+```python
+await api.state.get(scope="conversation", key="external.session_id")
+await api.state.set(scope="conversation", key="summary.checkpoint", value=...)
+```
+
+State 是可选寄宿能力。自管 runtime 可以完全不用；依附 LangBot 的官方 runner 可以使用。
+
+### 4.6 External harness context projection
+
+Claude Code、Codex、Kimi Code 这类 runtime 通常已经有自己的 session、工具 loop、MCP 加载、上下文压缩和工作目录。LangBot 不应把这类 runner 强行改造成“host prompt assembler”，而应提供可审计的事件和资源投影。
+
+推荐 projection 形态：
+
+- `agent-context.json`：结构化 JSON，包含 `run_id`、`event`、`actor`、`subject`、`input`、`delivery`、`resources`、`context`、`state`、`runtime`。
+- `LANGBOT_CONTEXT.md`：人类可读摘要，用于 code-agent harness 快速理解当前 IM 事件。
+- `resources`：只包含本次 run 授权后的模型、工具、知识库、artifact、state/storage 句柄，不暴露 Host 内部私有对象。
+- `skills`：Host 或 binding 把已授权 skill 投影为目标 harness 可读目录，例如 Claude Code 的 `.claude/skills/<name>/SKILL.md`。
+- `MCP config`：Host 或 binding 提供 scoped MCP 配置，runner adapter 转成目标 harness 的配置文件或 CLI 参数。
+- `state pointers`：外部 session id、working directory、checkpoint 等小型 JSON 状态通过 Host state API 保存，例如 `external.session_id`、`external.working_directory`。
+
+当前 Claude Code runner MVP 使用 schema `langbot.agent_runner.external_harness_context.v1`，并已通过 WebUI Debug Chat 验证 context 文件、skill 文件、MCP config 和 resume state 的基本链路。
+
+这类 projection 是“把 LangBot 事实源和授权资源交给 harness”，不是“由 LangBot 决定最终模型上下文”。外部 harness 可以继续使用自己的 transcript、工具权限和压缩策略。
+
+## 5. Runner manifest 中的上下文声明
+
+建议增加：
+
+```yaml
+context:
+  ownership: self_managed | host_bootstrap | hybrid
+  bootstrap: none | current_event | recent_tail | summary_tail
+  max_inline_events: 0
+  max_inline_bytes: 0
+  supports_history_pull: true
+  supports_history_search: true
+  supports_artifact_pull: true
+  owns_compaction: true
+  wants_static_context_refs: true
+```
+
+语义：
+
+- `self_managed`: Host 不主动 inline 历史，只提供 event 和 handles。
+- `host_bootstrap`: Host 为简单 runner inline 一个小窗口。
+- `hybrid`: Host inline summary/tail，runner 仍可按需拉更多。
+- `owns_compaction`: runner 负责压缩，host 不做语义摘要。
+- `wants_static_context_refs`: host 用 ref/hash 描述静态内容，减少重复 payload。
+
+## 6. KV cache 友好的上下文管理
+
+如果目标是支持 Claude Code SDK、Codex、Pi Agent SDK 等 runtime，必须避免每轮由 LangBot 重组大块 prompt。
+
+建议：
+
+- 稳定 session key：`workspace/bot/binding/runner/conversation/thread`。
+- 静态内容使用 `ref + version/hash`：system prompt、resource manifest、tool schema、platform policy。
+- 每轮只传 delta：当前 event、artifact refs、少量 runtime metadata。
+- 历史 append-only：不要每轮改写同一段 history 文本。
+- Summary checkpoint 稳定：只有压缩发生时产生新 checkpoint，不要每轮微调。
+- 大文件和工具结果 artifact 化。
+- Tool/context API schema 稳定，数据通过 API 拉取，而不是塞入 prompt。
+- 对自管 runtime，优先让它复用自身 session/cache，而不是强制 LangBot 每轮重放 transcript。
+
+## 7. Host guardrail
+
+Agent 自管 context 不代表无限制访问。LangBot 仍必须控制：
+
+- 每次 run 的 active `run_id`。
+- runner identity。
+- 当前 binding 的 resource policy。
+- conversation / actor / subject scope。
+- page size、artifact read size、API rate limit。
+- 跨会话读取权限。
+- 数据脱敏和敏感变量过滤。
+- 审计日志。
+
+Host 不负责“最佳上下文策略”，但负责“不越权、不爆内存、不不可审计”。
+
+## 8. 官方 runner 与业务编排边界
+
+官方 runner 插件可以选择把状态寄宿在 LangBot，但它们必须和第三方 runner 一样通过公开 Host APIs 消费这些能力。
+
+LangBot core 不应内置官方 agent 的业务流程：
+
+- 不内置 prompt 组装策略。
+- 不内置 tool loop。
+- 不内置 RAG 编排策略。
+- 不内置 summary / compaction 策略。
+- 不内置“local-agent 专用”的状态字段。
+
+官方 local-agent 应作为“依附 LangBot 基础设施的复杂 runner 参考实现”存在：
+
+- transcript / history 通过 `api.history.page()` 或 `api.history.search()` 读取。
+- summary、checkpoint、外部 session id、用户偏好通过 `api.state` 或 `api.storage` 保存。
+- 图片、文件、工具大结果通过 `api.artifacts` 读取。
+- 模型、工具、知识库通过 `api.models`、`api.tools`、`api.knowledge` 调用。
+
+这样 LangBot 保持为通用 agent host，不变成内置 agent 框架。
+
+## 9. 当前实现需要调整
+
+**已完成（当前分支）**：
+
+- ✅ `max-round` 不再是协议字段；类似历史窗口策略属于 runner binding config，而不是 Host / Pipeline 通用语义
+- ✅ 新 runner 默认不收到历史窗口
+- ✅ `AgentRunContext` 增加 `context` / cursor / access capabilities
+- ✅ `AgentRunAPIProxy` 增加 history / events / artifacts / state API
+- ✅ Host 增加持久 EventLog / Transcript / ArtifactStore / PersistentStateStore
+- ✅ `run_from_query()` 委托到 event-first `run(event, binding)`
+- ✅ Claude Code external harness smoke：context JSON / Markdown、skill、MCP config、`external.session_id` / `external.working_directory`
+
+这样 LangBot 既能服务依附 host 基础设施的官方 runner，也能服务自带 memory/session/cache 的外部 agent runtime。

+# Event Based Agent 预留设计
+
+> **注意**：本文档是 future design note，不是当前分支实现范围。
+>
+> EventGateway、EventRouter、Event subscription/notification 由其他分支实现。
+> 本分支只预留 event-first 入口和 envelope/binding models。
+> 2026-05-29 的 local-agent / Claude Code runner smoke 只验证本分支的 `run(event, binding)` 调度边界，不表示 EBA 分支已经完成联调。
+
+本文档描述未来 EBA 接入时，事件如何进入 LangBot、如何触发 AgentRunner，以及如何复用插件化 agent 基础设施。
+
+本阶段不实现完整 EventBus / EventRouter / Platform API。本阶段要做的是把协议边界设计对，避免当前消息入口继续绑死 Pipeline 和用户文本消息。
+
+## 1. 设计目标
+
+- 消息、撤回、入群、好友申请、定时任务、API 调用都能抽象为 host event。
+- EventRouter 可以根据 event type、bot、workspace、conversation、actor、subject 解析 AgentBinding。
+- AgentRunner 通过同一套 orchestrator 被调用。
+- 非消息事件不伪造成用户文本消息。
+- 平台动作执行通过显式 capability / permission / result type 预留，不混入普通文本回复。
+
+## 2. 事件不是消息
+
+`message.received` 只是事件的一种。协议不应假设：
+
+- 一定有用户文本。
+- 一定有 conversation history。
+- 一定要返回一条聊天消息。
+- actor 一定等于 sender。
+- subject 一定等于当前消息。
+
+例如：
+
+| event_type | actor | subject | input |
+| --- | --- | --- | --- |
+| `message.received` | 发消息的人 | 当前消息 | 文本、图片、文件等 |
+| `message.recalled` | 撤回操作者，未知时为系统 | 被撤回消息 | 通常为空 |
+| `group.member_joined` | 新成员或邀请人 | 群/成员关系 | 通常为空 |
+| `friend.request_received` | 申请人 | 好友申请 | 验证消息或申请理由 |
+| `schedule.triggered` | 系统 | 定时任务 | 任务 payload |
+| `api.invoked` | API caller | API request | request payload |
+
+## 3. Event Envelope
+
+建议事件 envelope：
+
+```python
+class AgentEventEnvelope(BaseModel):
+    event_id: str
+    event_type: str
+    event_time: int | None
+    source: EventSource
+    workspace_id: str | None
+    bot_id: str | None
+    conversation_id: str | None
+    thread_id: str | None
+    actor: ActorRef | None
+    subject: SubjectRef | None
+    input: AgentInput
+    delivery: DeliveryContext
+    raw_ref: RawEventRef | None
+    metadata: dict[str, Any] = {}
+```
+
+顶层字段使用 LangBot 稳定协议名。平台原始事件名和原始 payload 放到 `metadata` 或 `raw_ref`，不直接成为 runner 的稳定依赖。
+
+## 4. Event Source
+
+事件来源可以包括：
+
+- `platform_adapter`: 飞书、QQ、微信、Telegram 等 IM 平台。
+- `webui`: Debug Chat、控制台操作。
+- `http_api`: 外部系统调用 LangBot。
+- `scheduler`: 定时任务。
+- `system`: runtime、plugin、maintenance 事件。
+
+同一个 event source 可以产生多个 event type。EventRouter 不应该写死平台 adapter 的类名。
+
+## 5. Event Binding
+
+EBA 中，AgentBinding 取代 Pipeline runner 配置成为触发关系：
+
+```python
+class AgentBinding(BaseModel):
+    binding_id: str
+    enabled: bool
+    event_types: list[str]
+    scope: BindingScope
+    filters: list[EventFilter]
+    runner_id: str
+    runner_config: dict[str, Any]
+    resource_policy: ResourcePolicy
+    state_policy: StatePolicy
+    delivery_policy: DeliveryPolicy
+```
+
+Binding scope 示例：
+
+- workspace 全局。
+- bot 级别。
+- platform channel 级别。
+- conversation / group / thread 级别。
+- user / actor 级别。
+
+旧 Pipeline 可以迁移为 `message.received` 的 binding source，但不是唯一 binding source。
+
+## 6. EventRouter 调用链
+
+目标调用链：
+
+```text
+Platform Adapter / WebUI / API
+  -> Event Gateway normalize payload
+  -> EventLog append raw event
+  -> EventRouter resolve bindings
+  -> AgentRunOrchestrator.run(event, binding)
+  -> AgentRunContextBuilder.build(event, binding)
+  -> PluginRuntimeConnector.run_agent()
+  -> AgentRunResult stream
+  -> DeliveryController render / platform action
+```
+
+约束：
+
+- `run_from_event()` 必须复用现有 orchestrator 能力。
+- 不能为 EBA 单独实现另一套 plugin runner 调用协议。
+- 不能让非消息事件绕过 resource authorization。
+- Delivery 和 platform action 要走统一权限模型。
+- 外部 harness runner 也应通过同一套 envelope/binding/context/result 协议接入；EBA 不应为 Claude Code / Codex / Kimi Code 单独发明队列协议。
+
+## 7. Delivery Context
+
+Event 不一定回复到当前聊天窗口。需要显式 delivery：
+
+```python
+class DeliveryContext(BaseModel):
+    surface: str
+    reply_target: ReplyTarget | None
+    supports_streaming: bool
+    supports_edit: bool
+    supports_reaction: bool
+    max_message_size: int | None
+    platform_capabilities: dict[str, Any] = {}
+```
+
+消息事件通常带 reply target。系统事件可能没有默认 reply target，需要 runner 返回 `action.requested` 或由 binding 的 delivery policy 决定投递位置。
+
+## 8. AgentRunResult 与平台动作
+
+当前消息路径主要消费：
+
+- `message.delta`
+- `message.completed`
+- `run.completed`
+- `run.failed`
+
+EBA 后需要预留：
+
+- `action.requested`: 请求 host 执行平台动作。
+- `artifact.created`: runner 生成文件或大结果。
+- `delivery.requested`: 请求投递到某个 surface。
+
+示例：
+
+```json
+{
+  "type": "action.requested",
+  "data": {
+    "action": "friend.request.accept",
+    "target": {"platform": "wechat", "request_id": "..."},
+    "reason": "policy matched"
+  }
+}
+```
+
+Host 必须校验：
+
+- runner manifest 是否声明 platform_api capability。
+- binding 是否授权该 action。
+- actor / bot / workspace 是否允许。
+- 是否需要人工审批。
+
+本阶段如收到 `action.requested`，可以只记录 telemetry，不执行。
+
+## 9. 与 Context 协议的关系
+
+EBA 事件进入 AgentRunner 时仍使用 [AGENT_CONTEXT_PROTOCOL.md](./AGENT_CONTEXT_PROTOCOL.md) 的原则：
+
+- inline 当前事件。
+- 大 payload 用 raw/artifact ref。
+- 不默认 inline 完整 history。
+- agent 按需通过 API 拉 history/event/artifact/state。
+- Host 保留 EventLog 和权限 guardrail。
+
+非消息事件可以被投影进 Transcript，但不能强制伪装为 user message。AgentRunner 可以根据 event type 自己决定是否把它纳入模型上下文。
+
+## 10. 当前实现与目标差距
+
+**当前分支已落地（Event-first 基础设施）**：
+
+- ✅ `AgentRunOrchestrator` — event-first `run(event, binding)` 入口
+- ✅ `AgentRunContextBuilder` — event-first context 构建
+- ✅ `AgentEventEnvelope` 模型
+- ✅ `AgentBinding` 模型
+- ✅ `AgentRunResult` 基础消息流
+- ✅ `ctx.event` 的最小消息事件封装
+- ✅ `PipelineAdapter` — Query → Event + Binding 转换
+- ✅ `run_from_query()` → `run(event, binding)` 委托
+- ✅ EventLog / Transcript / ArtifactStore
+- ✅ History / Event / Artifact / State pull APIs
+- ✅ 当前消息事件 path 已用 `local-agent` 与 Claude Code external harness runner 做本地 smoke
+
+**其他分支负责（非本分支范围）**：
+
+- EventGateway 实现
+- EventRouter 实现
+- Event subscription / notification
+- EventLog 持久化管理 UI
+- AgentBinding 持久化 UI
+- 平台动作执行 (`action.requested` 执行器)
+
+**未来 EBA 完整落地需要**：
+
+- EventGateway 完整实现
+- EventRouter 与 BindingResolver 集成
+- AgentBinding 持久模型和 UI
+- DeliveryContext 完整实现
+- platform action permission model 和执行器
+- 真实平台事件接入
+
+## 11. 落地顺序
+
+1. 先把当前 Pipeline 消息入口适配成 `message.received` event。
+2. 增加 `AgentBinding` 抽象，先由 Pipeline config 生成。
+3. `AgentRunContextBuilder` 改为从 event + binding 构造 context。
+4. 引入 EventLog / Transcript。
+5. 增加非消息事件的协议测试，不接真实平台。
+6. 再接入真实 EventRouter 和 platform action。

+# LangBot Host 与 SDK 基础设施设计
+
+本文档描述 LangBot 和 SDK 为插件化 AgentRunner 共同提供的基础设施。它不以 Pipeline 为中心，也不以官方 local-agent 的实现方式为前提。
+
+## 1. 目标
+
+LangBot 要转为 agent host，而不是内置 runner 容器：
+
+- 接收 IM、WebUI、API 和未来 EventRouter 产生的事件。
+- 根据事件、bot、workspace、scope 解析应该调用的 agent binding。
+- 发现、校验和调用插件提供的 AgentRunner。
+- 为每次 run 提供受限资源、状态、存储、上下文引用和生命周期控制。
+- 接收 AgentRunner 返回的事件流，并投递到 IM、WebUI 或其他 output surface。
+
+SDK 要提供稳定协议：
+
+- `AgentRunner` 组件定义。
+- runner manifest / capabilities / permissions / config schema。
+- `AgentRunContext` 输入 envelope。
+- `AgentRunResult` 输出事件流。
+- `AgentRunAPIProxy` 运行期受限 API。
+
+## 2. 非目标
+
+- 不把 Pipeline 当作长期架构中心。
+- 不要求所有 AgentRunner 依赖 LangBot 的上下文管理。
+- 不要求官方 local-agent 的旧行为反向塑造 host 协议。
+- 不在 host 中实现通用 agentic prompt assembler。
+- 不强制 runner 使用 LangBot state / storage；LangBot 只提供可选、受控的寄宿能力。
+- **不实现 EventGateway**：EventGateway 是 future integration point，由外部 event branch 提供。本分支只定义 host-side envelope/binding models 和 `run(event, binding)` 入口。
+
+## 3. 分层架构
+
+目标结构：
+
+```text
+IM / WebUI / API / EventRouter (future)
+        |
+        v
+Event Gateway (future - external event branch)
+        |
+        v
+AgentBindingResolver
+        |
+        v
+AgentRunOrchestrator
+        |-- AgentRunnerRegistry
+        |-- AgentResourceBuilder
+        |-- AgentContextBuilder
+        |-- AgentRunSessionRegistry
+        |-- PersistentStateStore / EventLogStore / TranscriptStore / ArtifactStore
+        v
+Plugin Runtime / AgentRunner
+        |
+        v
+AgentRunResult stream
+        |
+        v
+Delivery / Renderer / Platform API
+```
+
+**当前状态**：
+- `PipelineAdapter` 作为当前入口 adapter，将 Pipeline Query 转换为 `AgentEventEnvelope` + `AgentBinding`
+- `run_from_query()` 内部委托到 `run(event, binding)`
+- EventLog / Transcript / ArtifactStore / PersistentStateStore 已落地
+- `local-agent` 与 Claude Code runner 已通过本地 WebUI smoke，验证同一条 `run(event, binding)` path 可服务 host-infra runner 与外部 harness runner
+- EventGateway 由外部 event branch 实现
+
+当前 Pipeline 只应接入在 Pipeline adapter 位置。它可以继续产生 `message.received`，但不应继续拥有 runner 选择、上下文裁剪和业务 agent 执行的核心语义。
+
+## 4. LangBot 侧能力
+
+### 4.1 Event Gateway（Future Integration Point）
+
+> **注意**：EventGateway 由外部 event branch 实现，不在本分支范围。本分支只预留 event-first 入口和 envelope/binding models。
+
+Event Gateway 将负责把入口统一成 host event：
+
+- IM 平台消息。
+- WebUI debug chat 消息。
+- API 触发。
+- 后续非消息事件，例如入群、撤回、好友申请。
+
+输出应是稳定 envelope，而不是 Pipeline Query 私有结构：
+
+```python
+class AgentEventEnvelope(BaseModel):
+    event_id: str
+    event_type: str
+    event_time: int | None
+    source: str
+    bot_id: str | None
+    workspace_id: str | None
+    conversation_id: str | None
+    thread_id: str | None
+    actor: ActorRef | None
+    subject: SubjectRef | None
+    input: AgentInput
+    delivery: DeliveryContext
+    raw_ref: RawEventRef | None
+```
+
+**当前 adapter source**：`PipelineAdapter.query_to_event(query)` 从 Pipeline Query 生成 `AgentEventEnvelope`。
+
+原始平台 payload 可以存为 raw event 或 artifact ref；不要把平台私有字段直接扩散到 AgentRunner 顶层协议。
+
+### 4.2 Agent Binding
+
+Agent binding 是”什么事件调用哪个 runner、带什么绑定配置”的持久配置。它替代长期依赖 Pipeline runner config 的角色。
+
+建议模型：
+
+```python
+class AgentBinding(BaseModel):
+    binding_id: str
+    scope: BindingScope
+    event_types: list[str]
+    runner_id: str
+    runner_config: dict[str, Any]
+    resource_policy: ResourcePolicy
+    state_policy: StatePolicy
+    delivery_policy: DeliveryPolicy
+    enabled: bool
+```
+
+**当前 adapter source**：`PipelineAdapter.pipeline_config_to_binding(query, runner_id)` 从 Pipeline config 生成临时 `AgentBinding`。
+
+Pipeline 当前可以被迁移为一种 binding source：
+
+- Pipeline AI runner config -> `AgentBinding`
+- Pipeline extension preference -> `resource_policy`
+- Pipeline output settings -> `delivery_policy`
+
+但新设计不应再把这些字段命名为 Pipeline 专属概念。
+
+### 4.3 AgentRunnerRegistry
+
+Registry 负责收集 runner descriptor：
+
+- 插件 runtime 提供的 `AgentRunner`。
+- 可能存在的 host adapter runner。
+- 开发期本地插件 runner。
+
+Descriptor 必须包含：
+
+```python
+class AgentRunnerDescriptor(BaseModel):
+    id: str
+    source: Literal["plugin", "host_adapter"]
+    label: I18nObject
+    description: I18nObject | None = None
+    capabilities: AgentRunnerCapabilities
+    permissions: AgentRunnerPermissions
+    config_schema: list[DynamicFormItemSchema]
+    plugin: PluginRef | None = None
+```
+
+`plugin:author/name/runner` 仍可作为稳定 id 格式。多个 binding 指向同一个 runner id 时，不创建多个插件实例。
+
+### 4.4 AgentRunOrchestrator
+
+Orchestrator 是唯一运行入口：
+
+```text
+run(event, binding)
+  -> resolve runner descriptor
+  -> build resources
+  -> build context
+  -> register run session
+  -> call plugin runtime
+  -> normalize result stream
+  -> update state
+  -> unregister run session
+```
+
+它负责：
+
+- `run_id` 生成和生命周期。
+- timeout / deadline / cancellation。
+- 插件异常隔离。
+- result schema 校验和大小限制。
+- state.updated 处理。
+- delivery backpressure 和 telemetry。
+
+`run_from_query()` 这类 API 可以保留为 Pipeline adapter 入口，但内部应转换成 event + binding 后走统一 `run()`。
+
+### 4.5 Resource Authorization
+
+LangBot 在每次 run 前生成 `ctx.resources`。资源来自三层约束：
+
+- runner manifest 声明的 permissions。
+- binding/resource policy 允许的资源范围。
+- 当前 event / actor / bot / workspace 的实际权限。
+
+资源类型包括：
+
+- models
+- tools
+- knowledge bases
+- files / artifacts
+- storage
+- platform capabilities
+- history / transcript access
+
+运行期 action 必须再次通过 `run_id` 校验。SDK 侧本地校验只用于开发体验，host 侧校验才是安全边界。
+
+### 4.6 State 与 Storage
+
+LangBot 可以提供 host-owned state，让 AgentRunner 把状态寄宿在 LangBot：
+
+- conversation state
+- actor state
+- subject state
+- runner/binding state
+- workspace state
+
+但这不是强制。外部 agent runtime 可以维护自己的 session 和 memory。LangBot 只需要提供：
+
+- 授权开关。
+- scope key。
+- get/set/list/delete API。
+- 持久化 backend。
+- 审计和清理策略。
+
+当前进程内 state store 只能作为过渡实现，不能作为正式生产语义。
+
+### 4.7 EventLog / Transcript / Artifact
+
+LangBot 应提供事实源能力：
+
+- `EventLog`: 保存原始事件、系统事件、工具调用、投递结果、错误。
+- `Transcript`: 面向对话 UI / agent history 的消息投影。
+- `ArtifactStore`: 保存大文件、多模态输入、工具大结果、平台附件。
+
+AgentRunner 可以读取这些能力，但不能被迫使用 LangBot 作为唯一记忆系统。
+
+### 4.8 External harness resource projection
+
+Claude Code、Codex、Kimi Code 等外部 harness runner 可能不会直接调用 LangBot 的 model/tool loop，而是把 LangBot 事件和授权资源投影到自己的 harness 中执行。Host 侧仍要保持统一边界：
+
+- Host 负责构造 event-first context、资源授权、state/storage、EventLog/Transcript/ArtifactStore 和审计。
+- Host 或 binding policy 负责决定哪些 MCP server、skill、artifact、history/state 句柄可以投影给 runner。
+- Runner plugin 负责把 scoped projection 转成目标 harness 可消费的形式，例如 context JSON/Markdown、MCP config、skill 目录、环境变量或 CLI 参数。
+- 外部 harness 负责自己的 native session、tool loop、压缩、权限模式和 resume 机制。
+
+当前 Claude Code runner MVP 已验证：
+
+- LangBot event-first context 可以写入 `agent-context.json` / `LANGBOT_CONTEXT.md`。
+- binding 中的 skill / MCP 配置可以投影到 Claude Code 原生目录和 CLI 参数。
+- `external.session_id` 与 `external.working_directory` 可以通过 Host state 保存并用于 resume。
+
+发布级路径隔离、secret 过滤、MCP allowlist、工具白名单、资源配额和 workspace 清理不属于当前协议闭环，详见 [SECURITY_HARDENING.md](./SECURITY_HARDENING.md)。
+
+## 5. SDK 侧协议
+
+### 5.1 AgentRunner 组件
+
+```python
+class AgentRunner(BaseComponent):
+    __kind__ = "AgentRunner"
+
+    @classmethod
+    def get_capabilities(cls) -> AgentRunnerCapabilities:
+        ...
+
+    @classmethod
+    def get_config_schema(cls) -> list[dict]:
+        ...
+
+    async def run(self, ctx: AgentRunContext) -> AsyncGenerator[AgentRunResult, None]:
+        ...
+```
+
+### 5.2 Capabilities
+
+建议能力声明：
+
+```yaml
+capabilities:
+  streaming: true
+  tool_calling: true
+  knowledge_retrieval: true
+  multimodal_input: true
+  event_context: true
+  platform_api: false
+  interrupt: true
+  stateful_session: true
+  self_managed_context: true
+  host_state: optional
+```
+
+`self_managed_context` 表示 runner 或外部 runtime 自己管理上下文。Host 不应给它强塞历史窗口，只提供当前事件和 context handles。
+
+### 5.3 Permissions
+
+```yaml
+permissions:
+  models: ["invoke", "stream", "rerank"]
+  tools: ["detail", "call"]
+  knowledge_bases: ["list", "retrieve"]
+  history: ["page", "search"]
+  events: ["get", "page"]
+  artifacts: ["metadata", "read"]
+  storage: ["plugin", "workspace", "binding"]
+  files: ["config", "knowledge"]
+  platform_api: []
+```
+
+权限声明是 runner 需要的最大能力，实际可用资源仍由 binding 和当前运行上下文裁剪。
+
+### 5.4 AgentRunContext
+
+Context 顶层应是 event-first，而不是 Query-first：
+
+```python
+class AgentRunContext(BaseModel):
+    run_id: str
+    trigger: AgentTrigger
+    event: AgentEventContext
+    conversation: ConversationContext | None = None
+    actor: ActorContext | None = None
+    subject: SubjectContext | None = None
+    input: AgentInput
+    resources: AgentResources
+    context: ContextAccess
+    state: AgentRunState
+    runtime: AgentRuntimeContext
+    config: dict[str, Any]
+```
+
+`messages` 可以作为兼容字段或 bootstrap 字段，但不应继续是协议核心。
+
+### 5.5 AgentRunResult
+
+输出应是事件流：
+
+```python
+class AgentRunResult(BaseModel):
+    type: Literal[
+        "message.delta",
+        "message.completed",
+        "tool.call.started",
+        "tool.call.completed",
+        "state.updated",
+        "artifact.created",
+        "action.requested",
+        "run.completed",
+        "run.failed",
+    ]
+    data: dict[str, Any] = {}
+```
+
+当前消息回复只消费 `message.delta` / `message.completed` / `run.failed`。平台动作执行等 EBA 和 platform API 权限落地后再启用。
+
+### 5.6 AgentRunAPIProxy
+
+Proxy 是 runner 访问 host 能力的唯一入口：
+
+- model APIs
+- tool APIs
+- knowledge APIs
+- state / storage APIs
+- history / event APIs
+- artifact APIs
+- platform APIs
+
+所有请求必须带 `run_id`，host 侧按 active run session 验证 runner identity 和 resource ACL。
+
+## 6. 当前实现与目标差距
+
+**已落地（当前分支）**：
+
+- ✅ `AgentRunnerRegistry`
+- ✅ `AgentRunOrchestrator` — event-first `run(event, binding)`
+- ✅ `AgentRunContextBuilder` — event-first context
+- ✅ `AgentResourceBuilder`
+- ✅ `AgentRunSessionRegistry`
+- ✅ `AgentRunAPIProxy` — model / tool / knowledge / history / event / artifact / state APIs
+- ✅ `PipelineAdapter` — Query → Event + Binding
+- ✅ `AgentBinding` 抽象
+- ✅ `AgentEventEnvelope` 抽象
+- ✅ `max-round` 从目标协议中移除；类似历史窗口参数若仍需要，应由具体 runner 的 manifest/config schema 暴露为 binding config
+- ✅ `PersistentStateStore` — 持久化状态存储
+- ✅ `EventLogStore` / `TranscriptStore` / `ArtifactStore`
+- ✅ history / artifact / event 的受限拉取 API
+- ✅ Claude Code external harness MVP：context/resource projection 与 host-owned resume state smoke
+
+**其他分支负责（非本分支范围）**：
+
+- EventGateway 实现
+- EventRouter 实现
+- AgentBinding 持久化 UI
+- platform API 动作执行
+- 发布级 security hardening
+
+## 7. 落地顺序
+
+**已完成**：
+
+1. ✅ 固化 README 路由和专题文档边界。
+2. ✅ 在 Host 中抽象 `AgentBinding`，由 Pipeline adapter 生成。
+3. ✅ 将 `AgentRunContextBuilder` 改为 event-first。
+4. ✅ 增加持久 transcript/event log/artifact/state 存储模型。
+5. ✅ 扩展 `AgentRunAPIProxy` 的 history / artifact / state API。
+6. ✅ 将 Pipeline-only 字段下沉到 Pipeline adapter。
+7. ✅ 官方 runner 插件迁移完成（7 个插件）。
+8. ✅ Claude Code runner MVP smoke：外部 harness context 投影和 state handoff。
+
+**后续工作（其他分支）**：
+
+- EventGateway 实现
+- EventRouter 与 BindingResolver 集成

+# Agent Runner 插件化当前实现与收尾计划
+
+> 2026-05-29 状态说明：本文档是实现推进计划和历史上下文，不是最新验收结论的唯一来源。当前设计入口见 [README.md](./README.md)，协议边界见 [PROTOCOL_V1.md](./PROTOCOL_V1.md)，进度见 [PROGRESS.md](./PROGRESS.md)，下一轮测试入口见 [PHASE1_QA_ACCEPTANCE_MATRIX.md](./PHASE1_QA_ACCEPTANCE_MATRIX.md)。
+
+本文档面向实现 agent，用来把当前 AgentRunner 插件化实现推进到可迁移状态。
+
+当前代码已经不是从零开始的 PoC。LangBot 已经具备 registry、orchestrator、context/resource builder、result normalizer 和插件 runtime action。本计划重点描述剩余工作：补齐宿主通用能力、对齐旧内置 runner 行为、完成官方 runner 插件迁移验收。
+
+## 1. 最终状态
+
+LangBot 最终只保留 Agent Runner 的宿主能力：
+
+- 发现 runner：`AgentRunnerRegistry`
+- 选择 runner：Pipeline 配置和未来事件绑定配置
+- 构造上下文：`AgentRunContext`
+- 裁剪资源：模型、工具、知识库、文件、存储、平台能力
+- 调度执行：`AgentRunOrchestrator`
+- 归一结果：`AgentRunResult` -> 当前 Pipeline 的 `Message` / `MessageChunk`
+- 隔离错误：插件异常、协议错误、超时、结果过大不能破坏主流程
+- 迁移旧配置：把旧内置 runner 配置迁到官方 AgentRunner 插件配置
+- 转发调用：插件 runtime 只维护已安装插件本身的运行实例，Pipeline 不创建插件实例或 runner 实例
+
+LangBot 不再长期维护内置业务 runner 分支。`local-agent`、Dify、n8n、Coze、DashScope、Langflow、Tbox 等都迁到官方 AgentRunner 插件。
+
+迁移期间允许旧 `RequestRunner` 文件继续存在，作为行为对齐基准和回退分析材料。它们不影响当前进度；真正的最终条件是主聊天执行路径不再依赖旧 runner。
+
+## 1.1 当前状态快照
+
+已完成或基本完成：
+
+- `AgentRunnerDescriptor`、runner id 解析、registry。
+- `AgentRunOrchestrator` 替换 `ChatMessageHandler` 内部 runner 调度。
+- `AgentRunContextBuilder`、`AgentResourceBuilder`、`AgentResultNormalizer`。
+- `ai.runner.id` + `ai.runner_config[id]` 的读取与旧配置映射。
+- AgentRunner runtime action：`LIST_AGENT_RUNNERS`、`RUN_AGENT`。
+- run-scoped proxy authorization：模型、工具、知识库、存储、文件。
+- EventLog / Transcript / ArtifactStore / PersistentStateStore。
+- Pipeline adapter 已委托到 event-first `run(event, binding)`。
+- `local-agent` 与 Claude Code runner 已通过本地 WebUI smoke。
+
+仍需收尾：
+
+- Docs final QA 与安装/发布文档整理。
+- timeout/deadline、取消、插件无输出、协议错误的端到端保护。
+- 官方 runner 插件安装/预装/迁移缺失处理。
+- 安全发布级 hardening：路径隔离、权限边界、secret、MCP/skill 投影策略、资源配额、审计。此项不阻塞当前协议闭环，详见 [SECURITY_HARDENING.md](./SECURITY_HARDENING.md)。
+- Codex / Kimi runner 全量接入、issue-centric 队列、复杂 workflow engine 和 EBA 分支完整联调。
+
+## 2. 高层架构
+
+```text
+Pipeline MessageProcessor / future EventRouter
+        |
+        v
+AgentRunOrchestrator
+        |
+        +--> AgentRunnerRegistry
+        |       +--> plugin runtime LIST_AGENT_RUNNERS
+        |       +--> descriptor cache / validation
+        |
+        +--> AgentRunContextBuilder
+        +--> AgentResourceBuilder
+        +--> AgentResultNormalizer
+        |
+        v
+PluginRuntimeConnector.run_agent()
+        |
+        v
+SDK Runtime RUN_AGENT -> plugin AgentRunner.run()
+```
+
+关键约束：
+
+- `ChatMessageHandler` 不解析 `plugin:*`，不实例化 wrapper，不知道 runner 组件细节。
+- `PipelineService.get_pipeline_metadata()` 不直接访问插件 runtime，而是读取 registry。
+- 旧 `RequestRunner` 只作为迁移参考，不作为最终运行路径。
+- `AgentRunOrchestrator` 是 LangBot 侧运行编排层：负责 runner 绑定解析、资源授权、context envelope provisioning、run scope 注册、插件调用和结果归一化；不负责决定 Agent 的最终 prompt/window/压缩策略。
+- 插件是无状态执行单元：多个 Pipeline 可以绑定同一个 runner id，并分别保存自己的 `ai.runner_config[id]`；运行时 LangBot 只把当前绑定配置放入 `ctx.config` 转发给同一个插件 runner。
+- 禁止按 Pipeline 或 runner config 创建多个插件实例。需要跨请求持久化的状态必须走明确授权的 plugin storage / workspace storage / 外部服务，不能隐式保存在 per-pipeline 插件对象里。
+- EBA 只做字段预留，不在本轮实现 EventBus、EventRouter、平台动作执行。
+
+## 3. 新增 LangBot 模块
+
+建议新增：
+
+```text
+src/langbot/pkg/agent/
+  __init__.py
+  runner/
+    __init__.py
+    descriptor.py
+    errors.py
+    id.py
+    registry.py
+    context_builder.py
+    resource_builder.py
+    orchestrator.py
+    result_normalizer.py
+    config_migration.py
+```
+
+### 3.1 descriptor.py
+
+定义 LangBot 内部使用的 descriptor：
+
+```python
+class AgentRunnerDescriptor(BaseModel):
+    id: str
+    source: Literal["plugin"]
+    label: dict[str, str]
+    description: dict[str, str] | None = None
+    plugin_author: str
+    plugin_name: str
+    runner_name: str
+    plugin_version: str | None = None
+    protocol_version: str = "1"
+    config_schema: list[dict[str, Any]] = []
+    capabilities: dict[str, bool] = {}
+    permissions: dict[str, list[str]] = {}
+    raw_manifest: dict[str, Any] = {}
+```
+
+`source == "builtin"` 不作为最终目标。如果实现阶段需要临时 adapter，必须标记为测试过渡代码，并在官方插件跑通后删除。
+
+### 3.2 id.py
+
+统一 runner id 解析和生成：
+
+- 插件 runner id：`plugin:{author}/{plugin_name}/{runner_name}`
+- `parse_runner_id(id)` 返回结构化对象
+- 禁止业务代码手写字符串 split
+- PoC 已存在的 `plugin:author/name/runner` 继续作为合法 id
+
+### 3.3 registry.py
+
+职责：
+
+- 调用 `ap.plugin_connector.list_agent_runners(bound_plugins=None)` 拉取插件 runner
+- 校验 manifest：
+  - `kind == AgentRunner`
+  - `metadata.name` 存在
+  - `metadata.label` 存在
+  - `spec.protocol_version` 兼容，默认 `1`
+  - `spec.config` 是 list，默认空
+  - `spec.capabilities` 是 dict，默认空
+  - `spec.permissions` 是 dict，默认空
+- 输出 `AgentRunnerDescriptor`
+- 缓存 discovery 结果，提供 `refresh()`
+- 单个插件 manifest 失败只记录 warning，不影响其它 runner
+
+刷新触发点：
+
+- 插件安装、卸载、升级、重启后
+- Pipeline metadata 请求时发现缓存为空
+- 可选 TTL，优先保证正确性
+
+### 3.4 context_builder.py / pipeline_adapter.py
+
+`context_builder.py` 只负责从 `AgentEventEnvelope + AgentBinding` 构造 SDK v1 `AgentRunContext`。Pipeline Query 的读取、参数过滤、prompt 提取和 `max-round` bootstrap 映射都属于 `PipelineAdapter`，不再放进 context builder。
+
+当前消息 Pipeline 进入 agent runner 的路径：
+
+```text
+Query
+  -> PipelineAdapter.query_to_event(query)
+  -> PipelineAdapter.pipeline_config_to_binding(query, runner_id)
+  -> PipelineAdapter.build_adapter_context(query, binding)
+  -> AgentRunOrchestrator.run(event, binding, adapter_context=...)
+  -> AgentRunContextBuilder.build_context_from_event(...)
+```
+
+Protocol v1 context 的稳定字段：
+
+- `run_id`: 新 UUID，不使用 query id 作为全局 run id
+- `trigger.type`: 事件触发类型，例如 `message.received`
+- `conversation`: conversation/thread/launcher/sender/bot/pipeline 投影
+- `event`: 稳定事件上下文
+- `actor`: 触发者
+- `subject`: 当前消息、群、频道或其它事件主体
+- `input`: 当前事件输入，不是历史消息窗口
+- `delivery`: 输出 surface 和平台投递能力
+- `resources`: 由 `resource_builder` 基于 binding policy 注入
+- `state`: `PersistentStateStore` 读取的 host-managed scoped state snapshot
+- `runtime`: host/version/workspace/bot/query/trace/deadline
+- `config`: 当前 binding 对该 runner id 的配置，即 `runner_config`
+- `bootstrap`: 可选小窗口，不是完整历史
+- `adapter`: Pipeline 或其它入口 adapter 的元数据
+
+Pipeline adapter 的 `prompt` 和公开业务变量不进入顶层协议字段：
+
+- filtered params -> `ctx.adapter.extra["params"]`
+- legacy/effective prompt 可以暂存到 `ctx.adapter.extra["prompt"]`，但 official
+  runner 不应把它当作行为契约
+- `max-round` working window 可以保留在 Pipeline adapter 兼容层，但 official
+  `local-agent` 不消费该 bootstrap/window
+- packaging 元数据 -> `ctx.runtime.metadata.context_packaging`
+
+现阶段不要把新的压缩或 token-budget 裁剪塞回 Pipeline stage。Pipeline 只负责入口适配；完整历史和长期上下文由 EventLog / Transcript / pull APIs / future ContextCompressor 支撑。
+
+### 3.4.1 Agentic context plan
+
+本轮只在 `PipelineAdapter` 中保留 `max-round` working window，不改变 user-round 选择规则。
+EventLog / Transcript / Host pull APIs 已落地，`ContextCompressor` 仍是设计预留。
+目标是让 Pipeline 逐步退化为入口 adapter，让 AgentRunner 层拥有上下文打包职责。
+
+建议最终拆成四个 host-side 服务：
+
+```text
+ConversationStore / EventLog
+  -> durable append-only raw messages, events, tool results, artifact refs
+ConversationProjection
+  -> converts events into agent-readable conversation history
+PipelineAdapter bootstrap policy
+  -> builds the bounded working context for one run
+ContextCompressor
+  -> creates and updates summaries/checkpoints when thresholds are exceeded
+```
+
+关键原则：
+
+- 完整历史属于 LangBot host，不属于插件实例。插件仍是 singleton/stateless。
+- `ctx.bootstrap.messages` 是 optional working context window，不是完整 conversation dump。
+- 每轮不能全量复制/序列化完整历史给插件 runtime；否则长会话会产生 O(n) 成本和跨进程 payload 膨胀。
+- `max-round` 的 user-round 规则只属于 Pipeline adapter 的 bootstrap 策略。
+- LiteLLM 接入后，context packaging 应升级为 token budget / summary / pull API 协作策略。
+- `ContextCompressor` 生成的是派生 summary/checkpoint，不能覆盖或删除 raw history。
+- 重启恢复依赖持久化 store 和 summary checkpoint，不依赖 `SessionManager` 里的进程内 conversation list。
+
+后续 `AgentRunContext` 可增加：
+
+```python
+context_request: AgentContextRequest | None
+context_packaging: ContextPackagingMetadata
+```
+
+建议语义：
+
+- `context_request.mode`: AgentRunner manifest / binding config 请求的 `max_round`、`token_budget`、`summary_hybrid`、`external_session`
+- `context_request.budget`: 模型窗口、预留输出 token、工具/RAG 预算等偏好
+- `context_packaging.policy`: Host 本次实际采用的打包策略
+- `context_packaging.delivered_count`: 本次下发的历史消息数
+- `context_packaging.source_total_count`: packager 可见的原始历史消息数
+- `context_packaging.messages_complete`: 本窗口是否已经包含完整历史
+- `context_packaging.cursor_before`: 未来通过 host API 读取更早历史的 cursor
+
+未来需要的受限 API：
+
+```python
+api.get_conversation_messages(cursor: str | None, limit: int) -> HistoryPage
+api.get_context_summary(scope: str = "conversation") -> ContextSummary | None
+api.request_context_compaction(policy: dict) -> CompactionResult
+```
+
+这些 API 必须绑定 `run_id`、runner id、actor/subject scope 和资源权限；Host 需要限制
+page size、总字节数、deadline 和可访问 conversation。
+
+### 3.4.2 Large artifacts and tool collaboration
+
+大文件、多模态输入和工具产物不要内联进 bootstrap messages 或 tool result。后续统一用
+artifact/resource ref 协作：
+
+- message/content 里只放小文本和必要摘要。
+- 大文件、图片、音频、长工具输出返回 `artifact_id`、`mime_type`、`size`、`digest`、
+  `summary`、`expires_at`、`permissions`。
+- `/tmp` 只能作为单次 run 的临时 staging，用于插件或工具短时间读写；它不是 durable store，
+  也不能作为重启恢复依据。
+- box/object storage 是长期 artifact 的目标位置。当前分支尚未合并 box 能力，因此本轮只写文档预留，不实现 API。
+- 工具之间传递大结果时应传 artifact ref，不传完整 blob。Agent 需要读取时走受限 proxy。
+
+未来建议 API：
+
+```python
+api.get_artifact_metadata(artifact_id: str) -> ArtifactMetadata
+api.open_artifact_stream(artifact_id: str) -> AsyncIterator[bytes]
+api.read_artifact_range(artifact_id: str, offset: int, length: int) -> bytes
+api.create_temp_artifact(name: str, content_type: str, ttl_seconds: int) -> ArtifactWriter
+```
+
+安全约束：
+
+- Host 校验 artifact 是否属于当前 run、conversation、actor/subject scope 或授权资源。
+- 默认不允许插件直接读任意本地路径，包括 `/tmp` 任意路径。
+- 临时文件应有 TTL 和清理机制；box artifact 应有 retention policy。
+- 多模态文件进入模型前，由 runner/context packager 决定传引用、摘要、缩略图还是实际 bytes。
+
+### 3.5 resource_builder.py
+
+执行前做三层裁剪：
+
+1. runner manifest 声明的 `spec.permissions`
+2. Pipeline 的 `extensions_preferences`
+3. 当前 Pipeline runner 绑定配置中选择的资源范围
+
+输出写入 `ctx.resources`，至少覆盖：
+
+- models：可调用模型 UUID、类型、能力摘要。包括 LLM、fallback LLM、rerank 等 runner config schema 中选择的模型类资源。
+- tools：可见工具 manifest，使用当前 bound plugins / MCP server 范围
+- knowledge_bases：可检索知识库列表
+- storage：plugin storage / workspace storage 权限摘要
+- files：允许读取的配置文件、知识文件摘要
+- platform_capabilities：本阶段只声明，不执行平台动作
+
+注意：旧的 unrestricted proxy action 必须二次校验，不能只靠 context 声明。AgentRunner 可用资源应来自 `ctx.resources`，不是插件 runtime 的全局能力。
+
+本阶段不接入 sandbox/skills，也不预留 runner 可见字段。后续相关分支合并后，
+执行、文件、skill、MCP 等能力应先由 Host 侧封装成普通 tool，再通过
+`ctx.resources.tools` 进入 runner；runner 不应识别或硬编码执行环境 provider。
+
+资源裁剪要尽量通用，不应只写死 local-agent：
+
+- `model-fallback-selector` 授权 primary/fallback LLM。
+- `llm-model-selector` 授权 LLM。
+- `rerank-model-selector` 授权 rerank 模型。
+- `knowledge-base-multi-selector` 授权知识库。
+- 后续新增 selector 时应在 resource builder 中统一扩展。
+
+### 3.5.1 future EventRouter 预留
+
+当前分支不实现 EBA EventRouter，但 AgentRunner 协议必须从现在开始兼容非消息事件。未来不要为消息撤回、群成员加入、好友申请各写一套 runner wrapper；统一入口应是：
+
+```text
+EventRouter -> AgentRunOrchestrator.run_from_event(event_request)
+```
+
+EBA 落地后，`ConversationStore` 不应只保存聊天消息，而应从 `EventLog` 投影生成：
+
+```text
+Platform Adapter
+  -> EventLog append raw event
+  -> ConversationProjection update message/history view when applicable
+  -> EventRouter resolve binding
+  -> AgentRunOrchestrator.run_from_event(event_request)
+  -> Context packager builds working context from projection + state + artifacts
+```
+
+这样消息事件、工具事件、群成员事件、好友申请事件可以共用同一套 run/session/state/resource
+边界；非消息事件也不需要伪造成一条用户文本消息。
+
+`event_request` 至少需要包含：
+
+- `event_type`: 稳定协议名，例如 `message.recalled`、`group.member_joined`、`friend.request_received`
+- `event_id` / `event_timestamp`
+- `event_data`: 平台原始 payload 摘要和 source event type
+- `actor`: 触发者，例如撤回操作者、新成员、好友申请人
+- `subject`: 事件作用对象，例如被撤回消息、群/成员关系、好友申请
+- `conversation`: 可选。群事件有 launcher 语义，好友申请可能还没有 conversation
+- `input`: 可选结构化输入。非消息事件允许 `text=None`、`contents=[]`
+- `binding`: 事件绑定解析出的 runner id、runner config、资源范围
+
+先保留的稳定事件名：
+
+- `message.received`
+- `message.recalled`
+- `group.member_joined`
+- `friend.request_received`
+
+这些事件名应作为插件协议的一部分保持稳定。平台原始事件名只能进入 `event_data`，不能成为 `ctx.event.event_type` 的公共契约。
+
+### 3.6 result_normalizer.py
+
+只接受 SDK v1 result：
+
+- `message.delta`
+- `message.completed`
+- `tool.call.started`
+- `tool.call.completed`
+- `state.updated`
+- `run.completed`
+- `run.failed`
+- `action.requested` 允许实验性返回，但本阶段只记录 telemetry，不执行
+
+映射：
+
+- `message.delta.data.chunk` -> `provider_message.MessageChunk`
+- `message.completed.data.message` -> `provider_message.Message`
+- `run.completed.data.message` -> `provider_message.Message`
+- `run.failed` -> 抛出受控异常，让 `ChatMessageHandler` 使用现有错误策略
+- 工具和状态事件默认不 yield 到 Pipeline，只记录 debug/telemetry
+
+防护：
+
+- 未知 type warning 后忽略
+- 单 result 序列化大小限制
+- provider message schema 校验失败转 `run.failed`
+- 插件没有输出任何消息时，按 runner failed 处理
+
+### 3.7 orchestrator.py
+
+核心入口：
+
+```python
+async def run_from_query(query: pipeline_query.Query) -> AsyncGenerator[Message | MessageChunk, None]:
+    runner_id = resolve_runner_id(query.pipeline_config)
+    descriptor = await registry.get(runner_id, bound_plugins=query.variables.get("_pipeline_bound_plugins"))
+    ctx = await context_builder.from_query(query, descriptor)
+    async for raw in plugin_connector.run_agent(...):
+        async for message in result_normalizer.normalize(raw):
+            yield message
+```
+
+必须覆盖：
+
+- runner id 不存在
+- 插件系统关闭
+- runner 不在 bound plugins 范围内
+- 插件 runtime 断连
+- runner 协议版本不兼容
+- run 超时
+- task cancellation
+
+## 4. 配置模型直接切换
+
+配置模型表达的是 Pipeline 到 runner id 的绑定，不表达插件实例。插件安装后由 plugin runtime 管理单个插件运行实例；不同 Pipeline 选择同一个 runner id 时，只是保存不同的 `runner_config[id]`，调用时随 `AgentRunContext.config` 传入。
+
+目标格式：
+
+```json
+{
+  "ai": {
+    "runner": {
+      "id": "plugin:langbot/local-agent/default",
+      "expire-time": 0
+    },
+    "runner_config": {
+      "plugin:langbot/local-agent/default": {}
+    }
+  }
+}
+```
+
+兼容读取：
+
+- 优先读 `ai.runner.id`
+- 没有 `id` 时读旧 `ai.runner.runner`
+- 旧内置 runner 名通过迁移表映射：
+  - `local-agent` -> `plugin:langbot/local-agent/default`
+  - `dify-service-api` -> `plugin:langbot/dify-agent/default`
+  - `n8n-service-api` -> `plugin:langbot/n8n-agent/default`
+  - `coze-api` -> `plugin:langbot/coze-agent/default`
+  - `dashscope-app-api` -> `plugin:langbot/dashscope-agent/default`
+  - `langflow-api` -> `plugin:langbot/langflow-agent/default`
+  - `tbox-app-api` -> `plugin:langbot/tbox-agent/default`
+
+写入策略：
+
+- 新 UI 只写 `ai.runner.id` 和 `ai.runner_config`
+- 后端 update 接口接受旧字段，但保存时归一成新格式
+- migration 最后统一落库
+
+## 5. 需要修改的 LangBot 范围
+
+必须修改：
+
+- `src/langbot/pkg/core/app.py`
+  - 增加 `agent_runner_registry` / `agent_run_orchestrator` 属性
+- `src/langbot/pkg/core/stages/build_app.py`
+  - 初始化 Agent 子系统
+- `src/langbot/pkg/pipeline/process/handlers/chat.py`
+  - 删除 `PluginAgentRunnerWrapper`
+  - 删除内置 runner 查找逻辑
+  - 调用 orchestrator
+- `src/langbot/pkg/api/http/service/pipeline.py`
+  - metadata 从 registry 生成
+- `src/langbot/pkg/plugin/connector.py`
+  - `list_agent_runners()` / `run_agent()` 增加协议校验和 bound plugin 参数
+- `src/langbot/pkg/plugin/handler.py`
+  - proxy action 二次权限校验
+- `src/langbot/pkg/pipeline/preproc/preproc.py`
+  - 不再只为 `local-agent` 构造工具、知识库、模型
+  - 对所有 agent runner 保留 multimodal input
+- `src/langbot/pkg/pipeline/pipelinemgr.py`
+  - runner name 监控改读 `runner.id`
+- `src/langbot/templates/metadata/pipeline/ai.yaml`
+  - runner 字段从 `runner` 迁到 `id`
+- `src/langbot/templates/default-pipeline-config.json`
+  - 默认 runner 改为官方 local-agent 插件 id
+- `web/src/app/home/pipelines/components/pipeline-form/PipelineFormComponent.tsx`
+  - 当前 runner 改读 `ai.runner.id`
+  - runner 配置区改写入 `ai.runner_config[id]`
+
+最终删除或停用：
+
+- `src/langbot/pkg/provider/runner.py` 的业务注册路径
+- `src/langbot/pkg/provider/runners/*` 的运行入口
+
+可以暂时保留文件作为官方插件迁移参考，但不应被运行时引用。
+
+## 6. 收尾实现顺序
+
+### Step 1：补齐宿主上下文
+
+- SDK `AgentRunContext` 保持 event-first：`event/input/delivery/resources/context/state/runtime/config/bootstrap/adapter`。
+- LangBot context builder 只从 `AgentEventEnvelope + AgentBinding` 写入稳定协议字段。
+- Pipeline adapter 可以把公开业务变量写入 `ctx.adapter.extra["params"]`；legacy/effective prompt 若保留在 `ctx.adapter.extra["prompt"]`，也只属于 adapter metadata。
+- 保持 `ctx.config` 只表达静态绑定配置。
+
+### Step 2：增强宿主 AgentRun proxy action
+
+- `invoke_llm` / `invoke_llm_stream` 通过 `run_id/query_id` 找回当前 Query。
+- 自动合并 model persisted `extra_args` 与 action-level override。
+- 自动应用 pipeline `remove-think`，并允许 action 显式 override。
+- `call_tool` 传回当前 Query，恢复旧工具调用上下文。
+- `retrieve_knowledge` 保持 `bot_uuid`、`sender_id`、`session_name` 等 settings。
+- `invoke_rerank` 使用 run-scoped model authorization。
+
+### Step 3：泛化资源构建
+
+- 按 manifest permissions + bound plugins/MCP + runner config schema 构造资源。
+- 支持 primary/fallback LLM、rerank model、KB selector。
+- 不把 local-agent 特例扩散到通用资源层。
+
+### Step 4：local-agent parity
+
+- 使用静态绑定配置 `ctx.config["prompt"]`，不读取 `ctx.adapter.extra["prompt"]`。
+- 通过 Host history API 拉取 transcript，不读取 `ctx.bootstrap.messages` 或 `ctx.adapter.adapter_messages`。
+- 当前 user message 从 `ctx.input.contents` 构造，保留多模态内容。
+- RAG 只替换/插入文本部分，不丢图片/文件。
+- streaming/non-streaming 默认跟随 `runtime.metadata.streaming_supported`。
+- 首轮 fallback 成功后，tool loop 固定使用 committed model。
+- tool loop 继续传可用 tools，支持多步工具调用。
+- rerank 通过授权模型资源调用。
+
+### Step 5：端到端保护和测试
+
+- 插件无输出时按 runner failed 处理。
+- timeout/deadline 覆盖 plugin runtime、模型调用和外部 runner 调用。
+- runner 协议错误转受控错误。
+- 覆盖 local-agent 用户可见行为：普通回复、流式、工具、多步工具、KB、rerank、多模态、绑定 prompt、history API。
+
+### Step 6：官方 runner 迁移
+
+- 官方插件 ready 后移除内置 runner registry
+- 删除或隔离 provider runners 的运行引用
+- 测试旧 runner 名只能通过 migration 映射到插件 id
+
+### Step 7：历史配置迁移
+
+- 写 persistence migration
+- 更新 default pipeline config
+- 对已存在 Pipeline 执行旧字段到新字段迁移
+- 对监控/日志里的 runner 字段改用新 id
+
+## 7. 测试要求
+
+单测：
+
+- runner id parse / format
+- registry manifest 校验、失败隔离、bound plugins 过滤
+- context builder 从 query 生成完整 v1 context
+- resource builder 三层裁剪
+- result normalizer 对每种 result type 的映射
+- 旧配置 resolve 和 migration
+
+集成测试：
+
+- fake AgentRunner 插件可被 Pipeline 选择
+- streaming 输出仍能更新 message card

+
+- LangBot Pipeline 可以选择插件 AgentRunner 并完成非流式和流式回复。
+- `ChatMessageHandler` 不包含插件 runner 解析和 wrapper。
+- `PipelineService` 不直接拼插件 runner metadata。
+- 所有 runner 配置使用 `ai.runner.id` + `ai.runner_config`。
+- 插件 runtime 不为每个 Pipeline 或 runner 配置创建插件实例；`runner_config` 只作为绑定配置随 `ctx.config` 传入。
+- 主聊天路径不再通过旧内置 runner 执行业务 runner。迁移期间旧文件可以保留。
+- 插件只能访问 `ctx.resources` 授权的模型、工具、知识库和文件。

+- 官方 `local-agent` 插件对外行为与旧内置 local-agent 对齐。
+- EBA 相关字段只作为 context/result 预留，不执行平台动作。

+# 官方 AgentRunner 插件迁移计划
+
+本文档描述内置 `RequestRunner` 迁出 LangBot 后，官方 runner 插件如何组织、迁移和验收。
+它是 [HOST_SDK_INFRASTRUCTURE.md](./HOST_SDK_INFRASTRUCTURE.md) 和
+[AGENT_CONTEXT_PROTOCOL.md](./AGENT_CONTEXT_PROTOCOL.md) 的下游落地计划，不是 LangBot
+宿主协议的设计前提。
+
+官方 `local-agent` 可以外移，也可以重写。设计重点不是保留旧内置 runner 的内部结构，
+而是验证一个依附 LangBot host 基础设施的官方 agent 能否完整工作。同时，LangBot 的
+host 协议必须服务 Claude Code SDK、Codex、Pi Agent SDK、外部 Agent 平台等自管
+context/runtime 的 runner，不能被官方插件的实现细节绑死。
+
+当前实现已经进入过渡阶段：
+
+- LangBot 主聊天路径通过 `AgentRunOrchestrator` 调用插件化 `AgentRunner`。
+- 旧 `src/langbot/pkg/provider/runners/*` 仍保留，作为迁移参考和回退分析材料；在官方插件迁移完成前不要求删除。
+- 官方 runner 当前以独立插件目录/仓库推进，例如 `langbot-local-agent/` 和 `langbot-agent-runner/*-agent/`。不再要求先落地单一 monorepo。
+- `claude-code-agent` 与 `codex-agent` 已作为外部 harness runner MVP 接入，用来验证 Claude Code / Codex / Kimi Code 这类自管 runtime 的边界。
+
+## 1. 为什么新仓库
+
+官方 runner 插件会和 LangBot 主仓库、SDK 仓库以不同节奏迭代：
+
+- LangBot 主仓库只维护宿主协议和调度。
+- SDK 仓库维护 AgentRunner 组件和 runtime 协议。
+- 官方 runner 插件承载业务 runner 的具体实现和第三方平台适配。
+
+不要把官方 runner 插件重新绑死在 LangBot 主仓库内。允许开发期使用本地路径插件，但运行边界必须保持为：
+
+- LangBot 提供通用宿主能力：当前事件、context handles、资源授权、状态/存储、历史、artifact、模型/工具/知识库调用代理、结果归一。
+- 插件消费这些公开能力，实现具体 runner 行为。
+- LangBot 默认不把全量历史消息 inline 给 runner；runner 按需通过授权 API 拉取历史和 artifact。
+- 旧内置 runner 只作为行为对齐的基准，不作为长期运行路径。
+
+## 2. 仓库结构
+
+当前推荐策略是“官方插件可独立发布，必要时共享 SDK helper”。开发期可以采用本地多目录布局：
+
+```text
+langbot-app/
+  langbot-local-agent/
+    manifest.yaml
+    components/agent_runner/default.yaml
+    components/agent_runner/default.py
+    pkg/
+    tests/
+  langbot-agent-runner/
+    claude-code-agent/
+    codex-agent/
+    n8n-agent/
+    ...
+```
+
+后续可以把多个官方 runner 聚合进 monorepo，也可以继续独立发布。这个选择不影响协议设计；协议边界由 SDK 和 LangBot 宿主保证。
+
+如果多个 runner 出现重复逻辑，优先沉淀到 SDK 或一个明确的共享 helper 包，不要把宿主私有结构泄漏给插件。
+
+## 3. 插件命名和 runner id
+
+固定映射：
+
+| 旧 runner | 官方插件 | runner id |
+| --- | --- | --- |
+| `local-agent` | `langbot/local-agent` | `plugin:langbot/local-agent/default` |
+| `dify-service-api` | `langbot/dify-agent` | `plugin:langbot/dify-agent/default` |
+| `n8n-service-api` | `langbot/n8n-agent` | `plugin:langbot/n8n-agent/default` |
+| `coze-api` | `langbot/coze-agent` | `plugin:langbot/coze-agent/default` |
+| - | `langbot/claude-code-agent` | `plugin:langbot/claude-code-agent/default` |
+| - | `langbot/codex-agent` | `plugin:langbot/codex-agent/default` |
+| `dashscope-app-api` | `langbot/dashscope-agent` | `plugin:langbot/dashscope-agent/default` |
+| `langflow-api` | `langbot/langflow-agent` | `plugin:langbot/langflow-agent/default` |
+| `tbox-app-api` | `langbot/tbox-agent` | `plugin:langbot/tbox-agent/default` |
+
+每个插件可以后续提供多个 runner，但迁移目标的默认 runner 统一叫 `default`。
+
+## 4. 迁移优先级
+
+### Batch 1：打通协议
+
+1. `local-agent`
+2. `claude-code-agent`
+3. `codex-agent`
+4. `dify-agent`
+
+原因：
+
+- `local-agent` 覆盖模型、工具、知识库、流式、会话历史，是能力最完整的基准。
+- `claude-code-agent` / `codex-agent` 代表 Claude Code / Codex / Kimi Code 这类本地或外部 code-agent harness：它们通常自带 session、tool loop、上下文压缩和权限模型，LangBot 主要提供 IM 事件、资源投影、审计和状态指针。
+- `dify-agent` 代表外部 Agent 平台调用，配置和错误处理能验证传统 service API runner 的迁移方式。
+
+### Batch 2：迁移外部 workflow runner
+
+1. `n8n-agent`
+2. `langflow-agent`
+
+这批主要验证 webhook/workflow 输入输出、timeout、外部 conversation id。
+
+### Batch 3：迁移平台 Agent API
+
+1. `coze-agent`
+2. `dashscope-agent`
+3. `tbox-agent`
+
+这批主要验证平台特有响应格式、引用资料、文件/图片输入。
+
+## 5. 每个官方插件的组件要求
+
+每个插件至少包含：
+
+```yaml
+apiVersion: langbot/v1
+kind: AgentRunner
+metadata:
+  name: default
+  label:
+    en_US: Dify Agent
+    zh_Hans: Dify Agent
+  description:
+    en_US: Run a Dify application as a LangBot AgentRunner.
+    zh_Hans: 将 Dify 应用作为 LangBot AgentRunner 运行。
+spec:
+  config: []
+  capabilities:
+    streaming: true
+    tool_calling: false

+    files: []
+    platform_api: []
+execution:
+  python:
+    path: ./main.py
+    attr: DefaultAgentRunner
+```
+
+## 6. local-agent 插件方向
+
+`local-agent` 是官方插件中的重要消费者，但不是宿主协议的设计中心。它可以选择复用
+旧实现，也可以完全重写。它需要证明：一个主要依附 LangBot host 能力的 agent runner
+可以通过公开协议完成模型、工具、知识库、状态、history、artifact、上下文压缩和消息投递。
+
+LangBot core 不应为了 local-agent 保留业务编排逻辑。local-agent 的 prompt 组装、history
+拉取、summary/checkpoint、tool loop、RAG 编排、fallback、多模态处理都应在插件内完成。
+
+迁移或重写时需要覆盖旧内置 runner 的用户可见能力：
+
+- model primary/fallback 选择
+- prompt
+- knowledge-bases
+- rerank-model
+- rerank-top-k
+- function calling
+- streaming
+- multimodal input
+- conversation history
+- monitoring metadata
+
+与 LangBot 主仓库的责任边界：
+
+- LangBot 构造当前事件、结构化输入、资源授权、context handles、state/storage 能力和 delivery 能力
+- LangBot 不默认 inline 全量历史，不替插件组装最终模型上下文
+- 插件负责选择模型、拼请求、调用 LLM、处理 tool call loop、输出 result stream
+- 插件不能绕过 `ctx.resources` 调用未授权模型、工具或知识库
+
+为了保持旧内置 runner 的用户可见行为，`local-agent` 插件应消费宿主处理后的有效输入和
+受限 API，而不是读取宿主内部私有结构：
+
+- `ctx.event` / `ctx.input`：当前结构化输入，必须保留图片、文件等多模态内容。
+- `ctx.context`：history cursor、inline policy、可用 context API。
+- `AgentRunAPIProxy.history`：按需读取 transcript，而不是依赖 host 每轮强塞历史窗口。
+- `AgentRunAPIProxy.artifacts`：按需读取图片、文件、工具大结果。
+- `AgentRunAPIProxy.state` / storage：保存 summary、外部 conversation id、用户偏好等可选状态。
+- `ctx.resources`：已授权模型、工具、知识库、文件和 storage。
+- `ctx.runtime.metadata.streaming_supported`：当前 adapter 是否能消费流式输出。
+- 宿主代理 action：模型、工具、知识库、rerank 调用必须通过 `run_id` 校验资源权限。
+
+`local-agent` 不应消费 Pipeline adapter 生成的 `max-round` / `bootstrap`
+窗口，也不应读取 `ctx.adapter.extra.prompt`。它应从绑定配置读取静态
+`prompt`，并通过 Host history API 拉取 transcript。Pipeline adapter 可以继续为旧入口
+保留 `max-round` 兼容逻辑，但这不是 official local-agent 的行为契约。
+
+建议 local-agent manifest 使用 hybrid 或 self-managed context：
+
+```yaml
+context:
+  ownership: hybrid
+  bootstrap: current_event
+  max_inline_events: 0
+  max_inline_bytes: 0
+  supports_history_pull: true
+  supports_history_search: true
+  supports_artifact_pull: true
+  owns_compaction: true
+  wants_static_context_refs: true
+```
+
+这表示：LangBot 只给当前事件和 context handles；local-agent 自己决定是否拉取历史、是否搜索、
+何时摘要、如何构造最终 prompt。
+
+### 6.1 Native Execution / Skills 后续接入
+
+本阶段不把 sandbox/skills 做成 AgentRunner 协议字段，也不预留 runner 可见字段。
+后续 sandbox/skills 分支合并后，命令执行、文件操作、skill、MCP managed process
+等能力应先由 LangBot Host 封装成 scoped tools，再通过 `ctx.resources.tools`
+暴露给 runner。
+
+这让 local-agent 只消费授权后的 Host 基础设施，而不是直接持有宿主机执行能力。
+Claude Code / Codex 这类外部 harness runner 仍可先保留自己的执行模型，但要在文档和
+配置中明确它们是否使用 LangBot 提供的工具投影。
+
+## 7. 外部 runner 插件要求
+
+外部平台 runner 迁移时遵循：
+
+- 旧配置字段尽量保持同名，便于 migration 复制
+- 输出统一转换为 `AgentRunResult`
+- 外部 API timeout 从 runner config 读取
+- 平台 conversation id 存 plugin storage 或 context runtime state，不能依赖 LangBot 内置 conversation uuid 私有结构
+- 流式支持按平台能力声明，没有流式就只发 `message.completed`
+
+### 7.1 Code-agent harness runner 要求
+
+Claude Code、Codex、Kimi Code 这类 runner 不一定通过 LangBot 的模型/工具 loop 执行。它们可以依赖自己的 harness，但仍必须遵守 LangBot 的宿主边界：
+
+- 输入来自 `ctx.event` / `ctx.input`，不能直接依赖 Pipeline 私有 `Query`。
+- LangBot 授权后的资源应被投影为 harness 可读的 context 文件、MCP 配置、skill 目录、环境变量或 CLI 参数。
+- 外部 session id、workspace、checkpoint 等跨轮次指针应写入 Host state 或 plugin storage；插件实例本身保持无状态。
+- CLI / subprocess runner 必须处理 timeout、取消、空输出、非零退出和 stderr 映射。
+- 如果外部 harness 选择使用 LangBot 托管执行能力，它应通过 scoped MCP/tool
+  投影消费 Host 授权资源；否则它属于 external harness mode，不能声称具备
+  LangBot-managed 执行隔离。
+- 外部 harness 的 permission mode、allowed/disallowed tools、MCP 配置只是一层执行约束；LangBot 仍负责调用前的资源授权、路径策略、secret 过滤和审计。发布级要求见 [SECURITY_HARDENING.md](./SECURITY_HARDENING.md)。
+
+### 7.2 SDK-owned LangBot MCP bridge
+
+Claude Code / Codex 这类外部 harness 不能直接持有 Python 进程内的
+`plugin_runtime_handler`，因此不能像 `local-agent` 一样直接调用
+`AgentRunAPIProxy`。当前轻量方案是由 SDK 提供一层 per-run MCP bridge：
+
+- `AgentRunner.create_external_mcp_bridge(ctx)` 是 runner 父类入口。
+- Bridge 由 `AgentRunAPIProxy` 和 `AgentRunContext` 构造，生命周期只覆盖当前 run。
+- Bridge 暴露 SDK 中显式注解的 `AgentRunExternalTools`，而不是扫描或导出全部 SDK action。
+- MCP tool schema 由注解和 Pydantic args model 生成；runner 插件不各自手写 LangBot tool schema。
+- stdio MCP proxy 只把外部 harness 的 MCP 调用转发回当前 run 的本地 bridge。
+- run 结束后 bridge 关闭；这不是 LangBot 主程序全局 MCP server。
+
+第一批工具保持很小：当前事件快照、history page、knowledge retrieve、authorized tool call。后续新增工具必须先进入 SDK-owned annotated surface，再由 MCP adapter 自动投影。
+
+## 8. Claude Code runner 当前形态
+
+当前 `claude-code-agent` 是最小可运行 MVP，用来证明外部 harness runner 可以接入同一套 AgentRunner 协议。
+
+### 8.1 基本行为
+
+- Runner ID：`plugin:langbot/claude-code-agent/default`
+- 执行方式：本地 Claude Code CLI print mode，默认命令为 `claude -p`
+- 默认输出：`message.completed` + `run.completed`
+- 默认权限：`permission-mode=plan`、`max-turns=1`、`disallowedTools=AskUserQuestion`
+- 默认状态：如果 Claude Code 返回 `session_id`，runner 通过 `state.updated` 写回 `external.session_id`
+- 工作目录：优先使用 binding config 的 `working-directory`，其次使用 Host state 中的 `external.working_directory`
+
+### 8.2 Context / skill / MCP 投影
+
+Claude Code runner 当前把 LangBot event-first context 投影给外部 harness：
+
+- 写入 `agent-context.json`，schema 为 `langbot.agent_runner.external_harness_context.v1`
+- 写入 `LANGBOT_CONTEXT.md`，作为人类可读摘要
+- 将 prompt prefix 指向 context 文件路径
+- 可把 binding 提供的 `skills-json` 写入 Claude Code 原生 `.claude/skills/<name>/SKILL.md`
+- 可把 binding 提供的 `mcp-config-json` 写成每次 run 的 MCP config，并通过 `--mcp-config` / `--strict-mcp-config` 传给 Claude Code
+- 可通过 `enable-langbot-mcp=true` 启用 SDK-owned per-run LangBot MCP bridge，使 Claude Code 通过 MCP 调用受限的 `AgentRunAPIProxy` 能力
+
+这些投影目前由 runner adapter 完成；长期更理想的形态是 LangBot Host 负责生成 scoped resource projection，runner 只负责适配 Claude Code 的原生目录和 CLI 参数。
+
+### 8.3 已验证能力
+
+2026-05-29 本地验证：
+
+- WebUI Debug Chat 能通过 Pipeline adapter 调用 `claude-code-agent`
+- Claude Code 能读取 LangBot context 文件并按指令输出 sentinel
+- Skill 文件可以投影到 `.claude/skills/`
+- MCP config 可以通过 binding config 投影为 Claude Code CLI 参数
+- SDK-owned per-run LangBot MCP bridge 可以被真实 Claude Code CLI 调用，并通过 `langbot_get_current_event` 读取当前 run_id
+- `external.session_id` 与 `external.working_directory` 可以写入 host-owned state，用于后续 resume
+- `codex-agent` 可通过 WebUI Debug Chat 调用本机 Codex CLI，读取 LangBot event context，并把 Codex `thread_id` 写入 host-owned state
+- SDK-owned per-run LangBot MCP bridge 可以被真实 Codex CLI 调用，并通过 `langbot_get_current_event` 读取当前 run_id
+- 对需要代理的本地运行环境，`codex-agent` 可通过 binding config 的 `environment-json` 显式传递非 secret 环境变量
+
+下一轮测试入口见 [PHASE1_QA_ACCEPTANCE_MATRIX.md](./PHASE1_QA_ACCEPTANCE_MATRIX.md)。
+
+### 8.4 当前限制
+
+- 不是发布级安全边界实现。
+- 默认只做本地 CLI 调用，不实现完整执行隔离或 workspace 生命周期。
+- 不实现 issue-centric 队列、复杂 workflow engine 或长期任务调度。
+- 不代表 Codex 发布级能力或 Kimi runner 已完成；当前只验证外部 harness runner 的协议形态。
+
+## 9. 发布和安装策略
+
+最终 LangBot 安装或升级时需要保证官方 runner 插件可用。可选方案：
+
+1. 首次启动检测缺失官方 runner 插件并提示安装。
+2. 打包发行版时预装官方 runner 插件。
+3. 在 migration 前检查对应插件是否存在，不存在则自动安装或阻止迁移。
+
+建议实现顺序：
+
+- 开发阶段使用本地路径插件。
+- 发布前支持 marketplace 安装。
+- 历史配置 migration 只在官方插件可用时执行。
+- 迁移期间保留旧内置 runner 文件，直到对应官方插件通过 parity 验收。
+
+## 10. 验收标准
+
+- 每个旧 runner 都有对应官方 AgentRunner 插件。
+- 旧 runner 配置能无损复制到新 `runner_config[id]`。
+- LangBot 主聊天路径不再通过 `RequestRunner` 执行业务 runner。
+- 官方插件测试覆盖非流式、流式、错误、timeout、配置缺失。
+- `local-agent` 插件能完成模型 fallback、tool calling、知识库检索、多模态输入、静态绑定 prompt 消费、history API 拉取、rerank。
+- `claude-code-agent` 或同类 code-agent harness runner 能消费 event-first context、投影 scoped resources、保存 external session state，并通过 WebUI Debug Chat smoke。
+- 对外行为与旧内置 local-agent runner 保持一致；代码结构不需要相同。

+# Agent Runner QA 指南
+
+本文档是 agent-runner 插件化下一轮测试的唯一 QA 入口。它合并并取代旧的 Phase 1 验收矩阵与 2026-05-18 / 2026-05-29 两份本地 QA 报告。
+
+目标不是保留完整历史流水账，而是指导测试 agent 用最小但高价值的路径判断当前分支是否仍然健康。
+
+## 1. 测试边界
+
+当前主线验证的是 AgentRunner Protocol v1：
+
+```text
+event -> binding -> runner.run(ctx) -> result stream
+```
+
+本指南验证：
+
+- Host 能通过当前 Pipeline adapter 进入 event-first `run(event, binding)` 主链路。
+- Runner 来自插件 registry，而不是旧内置 runner 分支。
+- `local-agent` 能消费 Host 模型、工具、知识库、history、state、artifact 等基础设施。
+- 外部 harness runner（Claude Code / Codex）能消费 event-first context，并把 session / working directory 等指针写回 host-owned state。
+- 错误、权限裁剪、无输出、timeout 等路径不会破坏主聊天流程。
+
+本指南不验证：
+
+- Runtime Control Plane v2。
+- EventGateway / EventRouter 完整落地。
+- 发布级 path isolation、secret filtering、MCP allowlist、资源配额和 workspace cleanup。
+- 所有外部服务 runner 的真实凭据联调。
+
+这些属于后续能力或发布门槛，分别见 [RUNTIME_CONTROL_PLANE_V2.md](./RUNTIME_CONTROL_PLANE_V2.md) 与 [SECURITY_HARDENING.md](./SECURITY_HARDENING.md)。
+
+## 2. 状态定义
+
+测试报告只使用以下状态：
+
+| 状态 | 含义 |
+| --- | --- |
+| PASS | 按步骤执行，用户可见行为和日志证据都满足通过条件。 |
+| FAIL | 环境可用，但行为不满足通过条件。 |
+| BLOCKED | 凭据、CLI、外部服务、测试数据或本地配置缺失导致无法执行。必须写清阻塞原因。 |
+| N/A | 当前 runner 或平台明确不支持该能力。必须引用 manifest、文档或配置说明。 |
+
+不能使用“看起来正常”“大概通过”“基本没问题”等模糊状态。
+
+## 3. 执行顺序
+
+推荐按以下顺序执行，前一层失败时不要继续扩大测试面：
+
+1. Host / SDK / runner 单测。
+2. WebUI 登录与 Pipeline Debug Chat 基础 smoke。
+3. `local-agent` 高价值场景。
+4. Claude Code / Codex 外部 harness smoke。
+5. 权限和错误路径补充检查。
+6. 汇总 PASS / FAIL / BLOCKED，并给出下一步建议。
+
+用户可见流程必须通过 WebUI 或真实消息平台验证。API / curl 只能作为诊断证据，不能单独让 UI case PASS。
+
+## 4. 必跑基线
+
+### 4.1 单测基线
+
+在 LangBot 仓库运行：
+
+```bash
+uv run --frozen pytest tests/unit_tests/agent
+```
+
+如果本次改动只触及默认配置或 API service，也至少补跑相关目标测试，例如：
+
+```bash
+uv run pytest tests/unit_tests/api/test_pipeline_service_defaults.py
+```
+
+通过条件：
+
+- agent 单测全 PASS，或失败项已确认与本次 agent-runner 路径无关。
+- 若失败来自 `context_builder`、`orchestrator`、`session_registry`、`resource_builder`、`plugin/handler.py` 的 run action 权限路径，不应进入 UI smoke。
+
+### 4.2 环境基线
+
+用 `langbot-skills` 做环境检查：
+
+```bash
+cd "$LANGBOT_SKILLS_REPO"
+bin/lbs env doctor
+bin/lbs case list
+```
+
+`LANGBOT_SKILLS_REPO` 指向当前工作区里的 `langbot-skills` 仓库。优先使用已有 case，而不是临时发明测试路径。
+
+推荐首批 case：
+
+- `webui-login-state`
+- `pipeline-debug-chat`
+- `local-agent-basic-debug-chat`
+- `local-agent-rag-debug-chat`（改动涉及 RAG / knowledge）
+- `local-agent-plugin-tool-call-debug-chat`（改动涉及 tool / resource policy）
+
+## 5. WebUI 主链路 Smoke
+
+### 5.1 Runner registry
+
+步骤：
+
+1. 打开 WebUI Pipeline 配置页。
+2. 查看 AI runner 下拉列表。
+3. 选择 `plugin:langbot/local-agent/default`。
+4. 保存并刷新页面。
+
+通过条件：
+
+- runner 选项来自插件 registry。
+- 保存后配置仍为 `ai.runner.id` + `ai.runner_config[id]`。
+- `runner_config` 表示 binding config，不表示插件实例状态。
+- 插件没有循环重启或 metadata 加载失败。
+
+### 5.2 主聊天路径
+
+步骤：
+
+1. 使用绑定 `plugin:langbot/local-agent/default` 的 Pipeline。
+2. 在 Debug Chat 发送确定性普通文本。
+3. 查看 WebUI 回复和后端日志。
+
+通过条件：
+
+- 用户可见回复正常。
+- 后端日志显示走 `AgentRunOrchestrator` / `RUN_AGENT`。
+- 不走旧内置 local-agent 主执行分支。
+- conversation transcript 写入用户消息和助手消息。
+
+## 6. `local-agent` 高价值测试
+
+只保留最能覆盖架构边界的场景。
+
+| ID | 场景 | 操作 | 通过条件 |
+| --- | --- | --- | --- |
+| LA-01 | 绑定 prompt | 配置 system prompt 后发送文本。 | runner 使用 `ctx.config.prompt`，不读取 `ctx.adapter.extra["prompt"]`；回复体现绑定 prompt。 |
+| LA-02 | history API | 连续两轮对话，第二轮引用第一轮 marker。 | runner 通过 Host history API 或自管上下文读取历史，不依赖 bootstrap window。 |
+| LA-03 | 流式 / 非流式 | 分别用支持流式和关闭流式的路径发送文本。 | 流式 UI 不重复、不空白；非流式只输出最终消息。 |
+| LA-04 | 工具调用 | 绑定测试工具，发送会触发工具的 prompt。 | `ctx.resources.tools` 只包含授权工具；工具调用 started/completed；最终回复包含工具结果。 |
+| LA-05 | RAG | 绑定测试知识库，发送命中文档的 prompt。 | `ctx.resources.knowledge_bases` 包含所选知识库；runner 通过授权 API 检索；回复使用检索内容。 |
+| LA-06 | 多模态 | 发送图片输入。 | `ctx.input.contents` 保留图片；支持视觉模型时正常处理，不支持时受控失败。 |
+| LA-07 | fallback / 错误 | 模拟 primary 模型失败或 runner 抛错。 | fallback 或 `run.failed` 行为受控；后续请求不受影响。 |
+| LA-08 | 无输出保护 | 测试 runner 完成但不产出消息。 | 不产生空白成功回复；按受控失败或明确缺陷处理。 |
+
+Rerank、remove-think、文件输入等场景只在本次改动直接涉及时补测，不作为每轮必跑项。
+
+## 7. 外部 Harness Runner Smoke
+
+这些测试用于验证 Claude Code / Codex 这类自管 runtime 能走同一条 Host 协议路径。若本机没有 CLI、登录态或代理配置，标记 BLOCKED，不要伪造 PASS。
+
+### 7.1 Claude Code runner
+
+步骤：
+
+1. 确认 `claude` CLI 在 LangBot runtime host 上可执行。
+2. 绑定 `plugin:langbot/claude-code-agent/default`。
+3. 使用保守权限模式和确定性 prompt。
+4. 在 Debug Chat 执行一次真实 smoke。
+5. 检查 context / skill / MCP projection 和 host-owned state。
+
+通过条件：
+
+- WebUI 可见回复包含预期 sentinel。
+- context JSON schema 为 `langbot.agent_runner.external_harness_context.v1` 或当前文档声明的等价 schema。
+- context 包含 event、input、delivery、resources、context、state。
+- 如启用 skills / MCP，投影路径和配置可被 Claude Code 读取。
+- `external.session_id` / `external.working_directory` 写入 host-owned state。
+- CLI missing、nonzero exit、timeout、empty output 都转成受控 `run.failed`。
+
+### 7.2 Codex runner
+
+步骤：
+
+1. 确认 `codex` CLI 在 LangBot runtime host 上可执行。
+2. 绑定 `plugin:langbot/codex-agent/default`。
+3. 如需要代理，使用 binding config 的 `environment-json` 显式传入。
+4. 在 Debug Chat 执行一次真实 smoke。
+5. 检查 JSONL 事件、last message、host-owned state。
+
+通过条件：
+
+- WebUI 可见回复包含预期 sentinel。
+- Codex JSONL 至少包含 thread/session 起始事件、agent message、turn completed。
+- `external.session_id` / `external.working_directory` 写入 host-owned state。
+- timeout/cancel 不遗留 orphan CLI 子进程。
+- CLI missing、nonzero exit、timeout、empty output 都转成受控 `run.failed`。
+
+### 7.3 API 型外部 runner
+
+Dify、n8n、Coze、DashScope、Langflow、Tbox 等外部服务 runner 不作为每轮必跑项。只有在本次改动触及对应 runner 或凭据已经可用时执行 smoke。
+
+通过条件：
+
+- runner 可选，配置可保存。
+- 请求成功，或外部服务错误被清晰返回。
+- 外部服务凭据缺失时标记 BLOCKED，并记录缺失项。
+
+## 8. 权限与隔离补充
+
+以下优先用单测 / targeted fixture 覆盖，不要求每次通过 UI 人工构造恶意 runner。
+
+| 场景 | 推荐证据 |
+| --- | --- |
+| 未授权模型调用被拒绝 | `plugin/handler.py` run action 权限测试或目标单测。 |
+| 未授权工具调用被拒绝 | `ctx.resources.tools` 与 host action 拒绝日志。 |
+| 未授权知识库检索被拒绝 | `ctx.resources.knowledge_bases` 与 host action 拒绝日志。 |
+| run_id 结束后复用被拒绝 | session registry 注销测试。 |

+| storage/state scope 越权被拒绝 | state/storage proxy 单测。 |
+
+如果这些单测失败，不能用 WebUI 正常回复替代。
+
+## 9. 证据要求
+
+每轮测试报告至少记录：
+
+- LangBot commit、SDK commit、相关 runner 插件 commit。
+- Pipeline UUID/name、runner id、关键 runner config 摘要。
+- WebUI 截图或 Playwright 操作记录。
+- 后端日志中对应 query id / run id 的关键行。
+- `langbot-skills` case/report 路径。
+- 外部 harness runner 的 context 文件、session id、working directory、CLI 错误摘要。
+- FAIL/BLOCKED 的复现步骤和归属仓库建议。
+
+报告结论必须回答：
+
+- 是否建议继续进入下一阶段测试。
+- 是否存在主聊天路径阻塞。
+- 是否只是凭据 / 外部服务 / 本机 CLI 缺失导致 BLOCKED。
+- 是否需要进入 [SECURITY_HARDENING.md](./SECURITY_HARDENING.md) 的发布级验收。
+
+## 10. 历史高价值记录
+
+历史报告已合并为本指南，不再保留单独文档。后续若需要追溯，优先查看 `langbot-skills/reports/` 下的原始执行报告。
+
+截至 2026-05-29，已有本地 smoke 证明：
+
+- `local-agent` 可以通过 Pipeline Debug Chat 走插件化 `AgentRunOrchestrator` 主链路。
+- Claude Code runner 可以通过同一条 `run(event, binding)` 路径执行。
+- Claude Code runner 可以读取 LangBot event-first context / skill / MCP 投影，并写回 `external.session_id` / `external.working_directory`。
+- Codex runner 可以通过同一条路径执行，并把 Codex `thread_id` 写回 host-owned state。
+
+这些记录只证明本地协议闭环可用，不代表发布级 security hardening 已完成。

+# LangBot AgentRunner Protocol v1
+
+本文档定义 LangBot Host 与插件 SDK / Runtime / AgentRunner 之间的协议合同。它优先描述”稳定接口应是什么”，不描述具体落地任务。
+
+## 当前状态
+
+**Protocol v1 已在当前分支落地**：
+
+- ✅ SDK 定义 `AgentRunnerManifest`、`AgentRunContext`、`AgentRunResult`、`AgentRunAPIProxy`
+- ✅ Runtime 支持 `LIST_AGENT_RUNNERS` 和 `RUN_AGENT`
+- ✅ Host 支持 `run_id` session authorization
+- ✅ Host 能从当前 Pipeline 入口生成 event-first context
+- ✅ `messages` 降级为 optional bootstrap
+- ✅ `max-round` 不出现在协议实体中；类似历史窗口参数若存在，应来自 runner manifest/config schema，并作为 binding config 进入 `ctx.config`
+- ✅ Proxy 覆盖 model、tool、knowledge、state/storage
+- ✅ History / Event / Artifact / State API 已落地
+- ✅ EventLog / Transcript / ArtifactStore / PersistentStateStore 已落地
+- ✅ `local-agent` 与 Claude Code runner 已通过本地 WebUI smoke，验证 host-infra runner 与外部 harness runner 共享同一协议路径
+
+## 1. 协议目标
+
+Protocol v1 要解决四件事：
+
+- LangBot 如何发现插件提供的 AgentRunner。
+- LangBot 如何把一次事件调用封装成 `AgentRunContext`。
+- AgentRunner 如何以事件流形式返回运行结果。
+- AgentRunner 如何通过受限 API 访问 LangBot host 能力。
+
+Protocol v1 不定义：
+
+- LangBot 内部如何持久化 AgentBinding。
+- AgentRunner 内部如何组装 prompt、压缩历史、管理 memory。
+- 官方 local-agent 的具体实现。
+- Pipeline 的长期配置模型。
+- 发布级安全 hardening 的完整实现；当前只定义 Host 侧资源、权限、状态和审计边界，release gate 见 [SECURITY_HARDENING.md](./SECURITY_HARDENING.md)。
+
+## 2. 参与方
+
+| 名称 | 职责 |
+| --- | --- |
+| LangBot Host | 事件入口、绑定解析、权限、资源、存储、生命周期、结果投递。 |
+| Plugin Runtime | 加载插件，响应 Host 的 runner discovery 和 run 调用。 |
+| AgentRunner | 插件提供的 agent 执行组件。 |
+| AgentRunAPIProxy | AgentRunner 访问 Host 能力的受限 API。 |
+| AgentBinding | Host 内部的事件到 runner 绑定配置，不直接暴露给 SDK。 |
+
+`AgentBinding` 只影响 Host 构造出的 `ctx.config`、`ctx.resources`、`ctx.context` 和 `ctx.delivery`。SDK 不需要知道 binding 的持久化形态。
+
+外部 harness runner（Claude Code、Codex、Kimi Code 等）仍然是 `AgentRunner`。Protocol v1 只要求它们消费 event-first `AgentRunContext`、返回 `AgentRunResult`，并通过 Host 授权的 state/storage/artifact APIs 保存跨轮次指针。它们内部可以继续使用自己的 session、tool loop、MCP、上下文压缩和权限模型。
+
+## 3. Discovery 协议
+
+### 3.1 LIST_AGENT_RUNNERS
+
+Host 调用 Plugin Runtime 获取当前插件暴露的 runner 列表。该请求不需要额外 payload。
+
+Runtime 返回：
+
+```python
+class ListAgentRunnersResponse(BaseModel):
+    runners: list[AgentRunnerManifest]
+```
+
+### 3.2 AgentRunnerManifest
+
+```python
+class AgentRunnerManifest(BaseModel):
+    id: str
+    name: str
+    label: I18nObject
+    description: I18nObject | None = None
+    capabilities: AgentRunnerCapabilities
+    permissions: AgentRunnerPermissions
+    context: AgentRunnerContextPolicy
+    config_schema: list[DynamicFormItemSchema] = []
+    metadata: dict[str, Any] = {}
+```
+
+字段要求：
+
+- `id` 必须稳定，推荐 `plugin:author/name/runner`。
+- `name` 是插件内 runner 名称，例如 `default`。
+- `config_schema` 只描述绑定配置表单，不代表插件实例状态。
+- `metadata` 只能放展示、诊断、非稳定扩展信息。
+
+### 3.3 Capabilities
+
+```python
+class AgentRunnerCapabilities(BaseModel):
+    streaming: bool = False
+    tool_calling: bool = False
+    knowledge_retrieval: bool = False
+    multimodal_input: bool = False
+    event_context: bool = True
+    platform_api: bool = False
+    interrupt: bool = False
+    stateful_session: bool = False
+    self_managed_context: bool = True
+```
+
+语义：
+
+- `streaming`: runner 可以返回 `message.delta`。
+- `tool_calling`: runner 可能调用 Host tool APIs。
+- `knowledge_retrieval`: runner 可能调用 Host knowledge APIs。
+- `multimodal_input`: runner 可以处理非纯文本 input / artifact。
+- `event_context`: runner 理解 event-first 输入。
+- `platform_api`: runner 可能请求平台动作。
+- `interrupt`: runner 支持取消或中断。
+- `stateful_session`: runner 可能维护跨 run 会话状态。
+- `self_managed_context`: runner 自己管理 working context，Host 不应默认 inline 历史。
+
+### 3.4 Permissions
+
+```python
+class AgentRunnerPermissions(BaseModel):
+    models: list[Literal["invoke", "stream", "rerank"]] = []
+    tools: list[Literal["detail", "call"]] = []
+    knowledge_bases: list[Literal["list", "retrieve"]] = []
+    history: list[Literal["page", "search"]] = []
+    events: list[Literal["get", "page"]] = []
+    artifacts: list[Literal["metadata", "read"]] = []
+    storage: list[Literal["plugin", "workspace", "binding"]] = []
+    files: list[Literal["config", "knowledge"]] = []
+    platform_api: list[str] = []
+```
+
+Manifest permissions 是 runner 需要的最大能力。实际可用资源还要经过 Host binding policy 和当前 run scope 裁剪。
+
+### 3.5 Context Policy
+
+```python
+class AgentRunnerContextPolicy(BaseModel):
+    ownership: Literal["self_managed", "host_bootstrap", "hybrid"] = "self_managed"
+    bootstrap: Literal["none", "current_event", "recent_tail", "summary_tail"] = "current_event"
+    max_inline_events: int = 0
+    max_inline_bytes: int = 0
+    supports_history_pull: bool = True
+    supports_history_search: bool = False
+    supports_artifact_pull: bool = True
+    owns_compaction: bool = True
+    wants_static_context_refs: bool = True
+```
+
+Host 使用该声明决定是否给 runner inline bootstrap history。默认原则：
+
+- Host 不得默认 inline 全量历史。
+- Host 默认只 inline 当前 event / input 和 context handles。
+- Runner 拥有 working context assembly。
+- Runner 可在授权后通过 Host history / event / artifact / state APIs 拉取更多上下文。
+- `max-round` 不属于 Protocol v1 字段，也不属于 Pipeline / Host 通用语义。
+
+## 4. Run 协议
+
+### 4.1 RUN_AGENT
+
+Host 调用 Runtime：
+
+```python
+class AgentRunRequest(BaseModel):
+    runner_id: str
+    runner_name: str
+    context: AgentRunContext
+```
+
+Runtime 返回 `AgentRunResult` 异步流。
+
+插件运行时可以继续在底层 transport 中使用 `plugin_author`、`plugin_name`、`runner_name` 定位组件，但协议语义以 `runner_id` 和 `context` 为准。
+
+### 4.2 AgentRunContext
+
+```python
+class AgentRunContext(BaseModel):
+    run_id: str
+    trigger: AgentTrigger
+    event: AgentEventContext
+    conversation: ConversationContext | None = None
+    actor: ActorContext | None = None
+    subject: SubjectContext | None = None
+    input: AgentInput
+    delivery: DeliveryContext
+    resources: AgentResources
+    context: ContextAccess
+    state: AgentRunState
+    runtime: AgentRuntimeContext
+    config: dict[str, Any] = {}
+    bootstrap: BootstrapContext | None = None
+    adapter: AdapterContext | None = None
+    metadata: dict[str, Any] = {}
+```
+
+核心约束：
+
+- `event` 是必选字段，Protocol v1 是 event-first。
+- `input` 表示当前事件的主输入，不等于历史消息。
+- `bootstrap` 是可选字段，不是完整 history。
+- `adapter` 只放 Pipeline adapter 字段，runner 不应依赖它做长期能力。
+- `config` 是 Host binding config，不是插件实例状态。
+
+### 4.3 AgentTrigger
+
+```python
+class AgentTrigger(BaseModel):
+    type: str
+    source: Literal["platform", "webui", "api", "scheduler", "system", "pipeline_adapter"]
+    timestamp: int | None = None
+```
+
+`trigger.type` 应与 `event.event_type` 一致或更粗粒度。例如 Pipeline 兼容入口触发消息时：
+
+```json
+{
+  "type": "message.received",
+  "source": "pipeline_adapter"
+}
+```
+
+### 4.4 AgentEventContext
+
+```python
+class AgentEventContext(BaseModel):
+    event_id: str
+    event_type: str
+    event_time: int | None = None
+    source: str
+    source_event_type: str | None = None
+    raw_ref: RawEventRef | None = None
+    data: dict[str, Any] = {}
+```
+
+要求：
+
+- `event_type` 使用 LangBot 稳定协议名，例如 `message.received`。
+- 平台原始事件名放入 `source_event_type`。
+- 大型原始 payload 必须放入 `raw_ref` 或 artifact，不应直接塞入 `data`。
+
+### 4.5 Actor / Subject / Conversation
+
+```python
+class ConversationContext(BaseModel):
+    conversation_id: str | None = None
+    thread_id: str | None = None
+    launcher_type: str | None = None
+    launcher_id: str | None = None
+    bot_id: str | None = None
+    workspace_id: str | None = None
+
+class ActorContext(BaseModel):
+    actor_type: str
+    actor_id: str | None = None
+    actor_name: str | None = None
+    metadata: dict[str, Any] = {}
+
+class SubjectContext(BaseModel):
+    subject_type: str
+    subject_id: str | None = None
+    data: dict[str, Any] = {}
+```
+
+示例：
+
+- 消息事件：actor 是发消息的人，subject 是当前消息。
+- 入群事件：actor 是新成员或邀请人，subject 是群/成员关系。
+- 定时事件：actor 可以是 system，subject 是 schedule。
+
+### 4.6 AgentInput
+
+```python
+class AgentInput(BaseModel):
+    text: str | None = None
+    contents: list[ContentElement] = []
+    attachments: list[ArtifactRef] = []
+    message_chain: dict[str, Any] | None = None
+```
+
+要求：
+
+- 文本、多模态、附件都属于当前 event input。
+- 大文件、图片、音频、工具大结果应以 artifact ref 传递。
+- `message_chain` 是平台兼容字段，不应成为长期稳定依赖。
+
+### 4.7 DeliveryContext
+
+```python
+class DeliveryContext(BaseModel):
+    surface: str
+    reply_target: dict[str, Any] | None = None
+    supports_streaming: bool = False
+    supports_edit: bool = False
+    supports_reaction: bool = False
+    max_message_size: int | None = None
+    platform_capabilities: dict[str, Any] = {}
+```
+
+Runner 可以参考 delivery 能力决定返回 `message.delta`、`message.completed` 或 `action.requested`。
+
+### 4.8 ContextAccess
+
+```python
+class ContextAccess(BaseModel):
+    conversation_id: str | None = None
+    thread_id: str | None = None
+    latest_cursor: str | None = None
+    event_seq: int | None = None
+    transcript_seq: int | None = None
+    has_history_before: bool = False
+    inline_policy: InlineContextPolicy
+    available_apis: ContextAPICapabilities
+```
+
+`ContextAccess` 告诉 runner：Host inline 了什么、没有 inline 什么、如果需要更多上下文应该通过哪些 API 拉取。
+它不是 Host 的业务上下文编排策略，而是 runner 按需读取上下文的入口说明。
+
+```python
+class InlineContextPolicy(BaseModel):
+    mode: Literal["none", "current_event", "recent_tail", "summary_tail"]
+    delivered_count: int = 0
+    source_total_count: int | None = None
+    messages_complete: bool = False
+    reason: str | None = None
+
+class ContextAPICapabilities(BaseModel):
+    history_page: bool = False
+    history_search: bool = False
+    event_get: bool = False
+    event_page: bool = False
+    artifact_metadata: bool = False
+    artifact_read: bool = False
+    state: bool = False
+    storage: bool = False
+```
+
+### 4.9 BootstrapContext
+
+```python
+class BootstrapContext(BaseModel):
+    messages: list[Message] = []
+    summary: str | None = None
+    artifacts: list[ArtifactRef] = []
+    metadata: dict[str, Any] = {}
+```
+
+约束：
+
+- `bootstrap.messages` 是 host convenience，不是协议核心。
+- 自管 context runner 默认应收到空 bootstrap 或只收到当前 event。
+- Host 不应为了”帮 agent 更聪明”而自动拼接完整 transcript。
+- 类似历史窗口策略应由具体 runner 的 binding config 表达；new/official runners 不应依赖 Pipeline adapter 下发的 bootstrap window。
+
+### 4.10 RuntimeContext
+
+```python
+class AgentRuntimeContext(BaseModel):
+    host: str = "langbot"
+    langbot_version: str | None = None
+    trace_id: str
+    deadline_at: float | None = None
+    locale: str | None = None
+    timezone: str | None = None
+    static_refs: dict[str, StaticContextRef] = {}
+    metadata: dict[str, Any] = {}
+```
+
+`static_refs` 用于 KV cache 友好的静态上下文引用，例如 system policy、tool schema、resource manifest 的 hash/version。
+
+### 4.11 State
+
+```python
+class AgentRunState(BaseModel):
+    conversation: dict[str, Any] = {}
+    actor: dict[str, Any] = {}
+    subject: dict[str, Any] = {}
+    runner: dict[str, Any] = {}
+```
+
+State 是可选 host-owned snapshot。Runner 也可以完全自管状态。
+
+## 5. Resources
+
+```python
+class AgentResources(BaseModel):
+    models: list[ModelResource] = []
+    tools: list[ToolResource] = []
+    knowledge_bases: list[KnowledgeBaseResource] = []
+    files: list[FileResource] = []
+    storage: StorageResource = StorageResource()
+    platform_capabilities: dict[str, Any] = {}
+```
+
+资源列表是本次 run 的授权结果。History / Event / Artifact 访问通过 permissions、`ctx.context.available_apis` 和 Host 侧 run session 校验控制，不作为可枚举 resource list 暴露。Runner 只能通过 `AgentRunAPIProxy` 访问这些能力。
+
+## 6. Result Stream
+
+### 6.1 AgentRunResult
+
+```python
+class AgentRunResult(BaseModel):
+    run_id: str
+    type: str
+    data: dict[str, Any] = {}
+    sequence: int | None = None
+    timestamp: int | None = None
+```
+
+### 6.2 稳定 result types
+
+| type | 说明 |
+| --- | --- |
+| `message.delta` | 流式消息片段。 |
+| `message.completed` | 完整消息。 |
+| `tool.call.started` | runner 开始工具调用的可观测事件。 |
+| `tool.call.completed` | runner 完成工具调用的可观测事件。 |
+| `artifact.created` | runner 生成 artifact。 |
+| `state.updated` | runner 请求更新 host-owned state。 |
+| `action.requested` | runner 请求 Host 执行平台动作。 |
+| `run.completed` | run 正常结束。 |
+| `run.failed` | run 失败。 |
+
+Host 必须忽略未知 result type 并记录 warning，除非该 type 明确要求强校验。
+
+### 6.3 message.delta
+
+```json
+{
+  "type": "message.delta",
+  "data": {
+    "chunk": {
+      "role": "assistant",
+      "content": "hel"
+    }
+  }
+}
+```
+
+### 6.4 message.completed
+
+```json
+{
+  "type": "message.completed",
+  "data": {
+    "message": {
+      "role": "assistant",
+      "content": "hello"
+    }
+  }
+}
+```
+
+### 6.5 state.updated
+
+```json
+{
+  "type": "state.updated",
+  "data": {
+    "scope": "conversation",
+    "key": "external.session_id",
+    "value": "abc"
+  }
+}
+```
+
+Host 必须校验 scope、key、value 大小和 JSON 可序列化性。
+
+### 6.6 action.requested
+
+```json
+{
+  "type": "action.requested",
+  "data": {
+    "action": "message.edit",
+    "target": {"message_id": "..."},
+    "payload": {"text": "..."}
+  }
+}
+```
+
+Protocol v1 只定义表达方式。Host 是否执行 action 取决于 platform API 能力、binding policy、审批策略和实现阶段。
+
+## 7. AgentRunAPIProxy
+
+所有 proxy action 必须携带 `run_id`。Host 必须校验：
+
+- active run session 存在。
+- caller plugin identity 匹配。
+- resource 在本次 `ctx.resources` 中授权。
+- scope 不越界。
+- payload size / rate limit / deadline 合法。
+
+### 7.1 Model APIs
+
+```python
+await api.models.invoke(model_id, messages, tools=None, extra_args=None)
+await api.models.stream(model_id, messages, tools=None, extra_args=None)
+await api.models.rerank(model_id, query, documents, top_k=None)
+```
+
+### 7.2 Tool APIs
+
+```python
+await api.tools.get_detail(tool_name)
+await api.tools.call(tool_name, parameters)
+```
+
+### 7.3 Knowledge APIs
+
+```python
+await api.knowledge.retrieve(kb_id, query_text, top_k=5, filters=None)
+```
+
+### 7.4 History APIs
+
+```python
+await api.history.page(
+    conversation_id=None,
+    before_cursor=None,
+    after_cursor=None,
+    limit=50,
+    direction="backward",
+    include_artifacts=False,
+)
+
+await api.history.search(
+    query,
+    filters=None,
+    top_k=10,
+)
+```
+
+History API 返回 Transcript projection，不返回原始平台 payload。
+
+### 7.5 Event APIs
+
+```python
+await api.events.get(event_id)
+await api.events.page(before_cursor=None, limit=50)
+```
+
+Event API 返回稳定 event envelope 或受限 raw ref，不默认返回大 payload。
+
+### 7.6 Artifact APIs
+
+```python
+await api.artifacts.metadata(artifact_id)
+await api.artifacts.read_range(artifact_id, offset=0, length=65536)
+await api.artifacts.open_stream(artifact_id)
+```
+
+Artifact API 必须支持大小限制、MIME 校验、过期时间和授权范围。
+
+### 7.7 State / Storage APIs
+
+```python
+await api.state.get(scope, key)
+await api.state.set(scope, key, value)
+await api.state.delete(scope, key)
+
+await api.storage.get(area, key)
+await api.storage.set(area, key, value)
+await api.storage.delete(area, key)
+await api.storage.list(area, prefix=None)
+```
+
+建议区分：
+
+- `state`: 小型 JSON 状态，适合 conversation / actor / runner / binding。
+- `storage`: blob 或较大数据，适合插件私有数据、workspace 数据、checkpoint。
+
+### 7.8 Platform APIs
+
+```python
+await api.platform.request_action(action, target, payload)
+```
+
+平台 API 是受限能力。默认不开放。需要 runner manifest、binding policy、用户审批策略同时允许。
+
+## 8. 错误模型
+
+Host API 错误统一返回：
+
+```python
+class AgentAPIError(BaseModel):
+    code: str
+    message: str
+    retryable: bool = False
+    details: dict[str, Any] = {}
+```
+
+建议 code：
+
+| code | 说明 |
+| --- | --- |
+| `unauthorized` | 未授权访问资源或 scope。 |
+| `not_found` | 资源不存在或对当前 runner 不可见。 |
+| `deadline_exceeded` | 超过 run deadline。 |
+| `payload_too_large` | 请求或响应过大。 |
+| `rate_limited` | Host 限流。 |
+| `invalid_argument` | 参数错误。 |
+| `runtime_error` | Host 或下游能力错误。 |
+
+Runner 失败使用 `run.failed`：
+
+```json
+{
+  "type": "run.failed",
+  "data": {
+    "code": "runner.error",
+    "message": "failed to call external agent",
+    "retryable": false
+  }
+}
+```
+
+## 9. Timeout 与 Cancellation
+
+Host 在 `ctx.runtime.deadline_at` 中下发总 deadline。SDK proxy 必须用该 deadline 限制单次 action timeout。
+
+取消语义：
+
+- Host 可以取消 active run。
+- Runtime 应尽力中断 runner。
+- Runner 支持中断时应返回或触发 `run.failed`，code 为 `cancelled`。
+- Host 必须 unregister active run session。
+
+## 10. Security 与 Guardrail
+
+Protocol v1 的安全边界在 Host：
+
+- Runner 不能直接访问未授权 model/tool/kb/history/artifact/storage。
+- SDK 本地校验只提升开发体验，不能替代 Host 校验。
+- 所有 resource id 对 runner 来说都是 opaque。
+- 默认只能访问当前 conversation / thread 的 history。
+- 跨会话、workspace 级 history 或 storage 必须额外授权。
+- 大 payload 必须 artifact 化。
+- Host 必须记录 run_id、runner_id、action、resource、scope、result。
+
+对外部 harness runner，边界进一步拆分为：
+
+- Host 在调用前完成 binding/resource policy 裁剪、路径策略、secret 过滤和审计记录。
+- Runner plugin 把授权后的 context/resource projection 适配为目标 harness 的 context 文件、MCP 配置、skill 目录、环境变量或 CLI 参数。
+- Claude Code / Codex / Kimi Code 等外部 harness 的 native permission mode、allowed/disallowed tools 和执行隔离策略只是额外执行约束，不能替代 Host 侧授权。
+- 外部 session id、working directory、checkpoint 等跨轮次指针应作为小型 JSON state 保存，例如 `external.session_id`、`external.working_directory`。
+
+完整路径隔离、MCP allowlist、secret redaction、配额、workspace 清理和发布级安全测试不属于当前 Protocol v1 smoke 闭环，详见 [SECURITY_HARDENING.md](./SECURITY_HARDENING.md)。
+
+Host 不负责业务编排：
+
+- 不拼接全量历史。
+- 不替 runner 做业务 prompt assembly。
+- 不内置 agent memory 策略。
+- 不内置 tool loop 业务流程。
+- 不内置上下文压缩策略。
+
+这些能力可以由官方或第三方 AgentRunner 插件实现，并通过公开 Host APIs 消费 LangBot 的状态、历史、存储、artifact、模型、工具和知识库能力。
+
+## 11. Pipeline Adapter
+
+Pipeline 是当前入口 adapter，不是协议中心。
+
+**当前分支已实现**：
+
+- ✅ `PipelineAdapter.query_to_event(query)` — 从 `Query` 构造 `AgentEventEnvelope`
+- ✅ `PipelineAdapter.pipeline_config_to_binding(query, runner_id)` — 从 Pipeline config 构造临时 AgentBinding
+- ✅ `run_from_query()` 委托到 `run(event, binding)`
+- ✅ runner-specific config 从 Pipeline 当前绑定配置透传到 `AgentBinding.runner_config` / `ctx.config`
+- ✅ Query-only 字段放入 `adapter` context
+
+Pipeline adapter 负责：
+
+- 从 `Query` 构造 `AgentEventContext`。
+- 从 Pipeline config 构造临时 AgentBinding。
+- 从当前 runner binding config 构造 `ctx.config`。
+- 保留必要的 legacy adapter metadata，但不定义历史窗口、prompt 组装或 agentic context 策略。
+- 将 Query-only 字段放入 `adapter`。
+
+Runner 不应长期依赖 `adapter`。新 runner 应只依赖 event-first context 和 Host APIs。
+
+## 12. 最小 v1 完成标准
+
+Protocol v1 已在当前分支完成：
+
+- ✅ SDK 定义 `AgentRunnerManifest`、`AgentRunContext`、`AgentRunResult`、`AgentRunAPIProxy`
+- ✅ Runtime 支持 `LIST_AGENT_RUNNERS` 和 `RUN_AGENT`
+- ✅ Host 支持 `run_id` session authorization
+- ✅ Host 能从当前 Pipeline 入口生成 event-first context
+- ✅ `messages` 降级为 optional bootstrap
+- ✅ `max-round` 不出现在协议实体中；类似参数属于具体 runner binding config
+- ✅ Proxy 至少覆盖 model、tool、knowledge、state/storage
+- ✅ History / event / artifact API 已落地
+- ✅ EventLog / Transcript / ArtifactStore / PersistentStateStore 已落地
+- ✅ 外部 harness runner 最小 smoke 已落地：Claude Code runner 能消费 event-first context、返回消息、写回 `external.session_id` / `external.working_directory`
+
+## 13. 开放问题
+
+- `AgentBinding` 是否需要进入 SDK 文档作为只读诊断信息，还是完全 Host 内部。
+- `TranscriptItem` 的最小字段集如何定义。
+- ArtifactStore 是否复用现有 BinaryStorage backend，还是引入独立实体。
+- State 与 Storage 的边界是否需要更强类型。
+- `platform_api` action 的审批模型如何表达。
+- 多 runner 并发处理同一 event 时，result delivery 的冲突策略如何定义。
+- Host 侧 scoped MCP / skill / workspace projection 是否需要从 runner config 上移为一等 resource projection API。

+# Agent Runner 插件化文档入口
+
+本文档是 agent-runner 插件化工作的路由页。具体设计拆到独立文档中维护，避免把 LangBot 宿主架构、SDK 协议、上下文管理、EBA 预留和官方 runner 迁移混在同一份 README 里。
+
+## 本分支目标
+
+**本分支目标：AgentRunner 外化 / 插件化基础设施**
+
+本分支只做 LangBot 作为 Agent Host 的基础能力建设：
+
+- LangBot 与 SDK 的稳定协议合同（Protocol v1）
+- Host-side `AgentEventEnvelope` / `AgentBinding` 模型
+- `run(event, binding)` event-first 入口
+- `PipelineAdapter`：Pipeline Query → AgentEventEnvelope + AgentBinding
+- EventLog / Transcript / ArtifactStore / PersistentStateStore
+- History / Event / Artifact / State pull APIs
+- SDK runtime forwarding pull APIs + `caller_plugin_identity` 验证路径
+
+## 本分支不实现
+
+以下能力由其他分支负责，本分支只预留 integration point：
+
+- **EventGateway**：完整事件网关实现、事件路由、事件持久化管理
+- **Event subscription / Event notification**：事件订阅、推送通知
+- **BindingResolver persistence UI**：绑定配置的持久化 UI 和 event router 集成（如由其他模块负责）
+- **Scheduler / Background event source**：定时任务、后台事件源
+- **Runtime control plane v2**：runtime registry、heartbeat、task queue、daemon claim、progress/cancel 和 runtime audit
+
+EventGateway 在本文档中描述为 **future integration point**，由外部 event branch 提供。本分支只定义 host-side envelope/binding models 和 `run(event, binding)` orchestrator 入口。
+
+## 当前状态
+
+**当前 Pipeline 是入口 adapter，不再是 agent runner 设计核心。**
+
+当前主入口仍可由 Pipeline 触发，但内部已转换成 event-first path：
+
+1. `run_from_query()` 使用 `PipelineAdapter.query_to_event(query)` 转换为 `AgentEventEnvelope`
+2. `run_from_query()` 使用 `PipelineAdapter.pipeline_config_to_binding(query, runner_id)` 转换为 `AgentBinding`
+3. `run_from_query()` 委托到 `run(event, binding, bound_plugins, adapter_context)`
+
+Pipeline path 已获得 event-first host capabilities：
+- EventLog / Transcript 写入
+- ArtifactStore 注册
+- PersistentStateStore 状态持久化
+- History / Event / Artifact / State pull APIs 可用

+## 工作拆分
+
+### 1. LangBot + SDK 基础设施
+
+目标是把 LangBot 从内置 runner 执行器变成 agent host：
+
+- LangBot 与 SDK 的稳定协议合同
+- runner manifest / descriptor / registry
+- agent binding 与配置解析
+- run orchestration 和生命周期管理
+- resource authorization 与 `run_id` 级权限校验
+- host-owned state / storage / event log / transcript / artifact 能力
+- SDK `AgentRunner`、`AgentRunContext`、`AgentRunResult`、`AgentRunAPIProxy`
+
+协议合同详见 [PROTOCOL_V1.md](./PROTOCOL_V1.md)。
+
+详见 [HOST_SDK_INFRASTRUCTURE.md](./HOST_SDK_INFRASTRUCTURE.md)。
+
+### 2. Agent-owned context
+
+LangBot 不应成为最终 agentic context manager。它应提供事实源、默认上下文引用和按需读取 API；agent 或其背后的 runtime 负责历史剪裁、摘要、召回和 KV cache 策略。
+
+`max-round` 这类历史窗口参数不应作为目标协议继续扩展；如果某个 runner 仍需要类似策略，应由该 runner 的 manifest/config schema 暴露为 binding config。
+
+详见 [AGENT_CONTEXT_PROTOCOL.md](./AGENT_CONTEXT_PROTOCOL.md)。
+
+### 3. Event Based Agent（Future）
+
+消息只是事件的一种。后续 `message.received`、`message.recalled`、`group.member_joined`、`friend.request_received` 等事件都应能通过统一事件 envelope 触发 AgentRunner。
+
+**本分支不实现 EBA 完整能力，只预留：**
+- event-first envelope (`AgentEventEnvelope`)
+- AgentBinding model
+- `run(event, binding)` 入口
+- PipelineAdapter（当前 AgentEventEnvelope / AgentBinding 的 Pipeline adapter source）
+
+详见 [EVENT_BASED_AGENT.md](./EVENT_BASED_AGENT.md)。
+
+### 4. 官方 runner 插件
+
+官方 `local-agent` 和外部 runner 迁移是下游工作。它们需要依附 LangBot 提供的宿主能力，但不应反过来决定宿主协议。
+
+`local-agent` 可以外移，也可以重写。验收重点是它能完整消费 LangBot 的模型、工具、知识库、存储、事件、history API 和 result stream，而不是保留旧内置 runner 的内部结构。
+
+详见 [OFFICIAL_RUNNER_PLUGINS.md](./OFFICIAL_RUNNER_PLUGINS.md)。
+
+### 5. Runtime Control Plane v2（Future）
+
+当前 AgentRunner v1 主线只负责 `event -> binding -> runner.run(ctx) -> result stream`。
+后续 Agent Platform v2 可以在 Host 侧新增 runtime registry、heartbeat、task queue、daemon claim、progress/cancel 和 runtime audit。
+
+在这些 Host 能力之上，可以构建独立 agent 管控面插件；插件负责 UI、策略和编排体验，runtime/task 的事实源仍由 Host 持有。
+
+详见 [RUNTIME_CONTROL_PLANE_V2.md](./RUNTIME_CONTROL_PLANE_V2.md)。
+
+## 已确认决策
+
+- 一个插件可以声明多个 `AgentRunner` 组件，每个组件独立暴露 manifest、配置 schema、能力和权限。
+- 插件本身按单实例、无状态执行单元理解；不同绑定不创建多个插件实例。
+- 绑定只保存 runner id 和绑定配置，不代表插件实例状态。
+- LangBot 可以提供 host-owned state / storage 能力，让 runner 把状态寄宿在 LangBot；但这应该是授权能力，不是强制要求。
+- 官方 runner 插件是协议消费者，不是协议设计的优先约束。
+- Pipeline 是当前入口 adapter，不是未来架构中心。
+- EventGateway 是 future integration point，由外部 event branch 提供。
+- Runtime control plane 是 v2 Host capability layer，不阻塞当前 AgentRunner v1 主线；agent 管控面插件应构建在该 Host 能力层之上。

+# Agent Runtime Control Plane V2
+
+本文档记录后续 Agent Platform / runtime 管控面的设计方向。它是当前讨论中的 **v2 文档**，但这里的 v2 指 Host capability layer / runtime control plane，不是 `AgentRunner Protocol v2`，也不属于当前 AgentRunner Protocol v1 插件化主线的交付范围。
+
+## 1. 结论
+
+当前主线应继续收口 AgentRunner v1：
+
+```text
+message/event -> binding -> runner.run(ctx) -> result stream
+```
+
+Runtime Control Plane v2 在 Host 侧新增 runtime control plane：
+
+```text
+event -> task -> runtime selection -> daemon claim -> execute -> progress/audit/result
+```
+
+在 Runtime Control Plane v2 之上，可以构建独立的 agent 管控面插件。插件负责 UI、策略和编排体验；runtime、task、heartbeat、audit 的事实源必须属于 LangBot Host，而不是插件私有 storage。
+
+## 2. 不影响 v1 主线
+
+v2 不应改变 AgentRunner v1 的基本契约：
+
+- 现有 `local-agent`、Dify、n8n、Coze 等 runner 仍可按 v1 直接执行。
+- 当前 Claude Code / Codex MVP runner 可以继续作为本机 subprocess 开发路径。
+- Host v1 已有的 event-first context、resource authorization、history / event / artifact / state / storage pull APIs 继续保留。
+- Pipeline 仍只是当前入口 adapter，不参与 v2 runtime 管控面的设计中心。
+
+v2 只是在 Host 上新增一层可选能力。需要管控面的 runner 或管理插件可以声明使用它；不需要的 runner 不受影响。
+
+## 3. 当前 Host 能力与缺口
+
+当前 Host 已经具备 v2 的基础设施底座：
+
+- `AgentEventEnvelope` / `AgentBinding`
+- run-scoped resource authorization
+- EventLog / Transcript / ArtifactStore / PersistentStateStore
+- History / Event / Artifact / State / Storage pull APIs
+- AgentRunner result stream 和受控错误回流
+- binding config 与 host-owned state
+
+这些能力足够支持一次 `runner.run(ctx)` 内的安全执行，但不足以承担完整 runtime 管控面。
+
+v2 还需要 Host 新增：
+
+- runtime registry：runtime id、所属 workspace、所在机器、provider 能力、状态。
+- capability discovery：`claude` / `codex` / 其它 CLI 是否存在、版本、登录状态、执行隔离能力。
+- heartbeat / liveness：runtime 在线、忙闲、最后心跳、可用 slot。
+- task queue：enqueue、claim、start、progress、complete、fail、cancel。
+- workspace mapping：LangBot workspace / project 如何映射到 runtime 上的真实目录、仓库或挂载。
+- secret / env projection：按授权向 runtime 投影 token、代理、MCP 配置、技能和环境变量。
+- runtime audit：stdout、stderr、事件流、产物、失败原因、执行耗时、使用量。
+- control API / UI：选择 runtime、测试 runtime、查看状态、下线、取消任务、重试任务。
+
+## 4. 角色边界
+
+### 4.1 LangBot Host
+
+Host 是事实源和控制面内核：
+
+- 保存 runtime / task / heartbeat / audit 状态。
+- 做权限校验、资源裁剪、workspace 绑定和审计。
+- 决定任务是否可被某 runtime claim。
+- 将执行结果统一回写到 event / transcript / artifact / state。
+
+Host 不应内置具体 agent CLI 的复杂业务逻辑，也不应把某个官方 runner 的特殊行为提升为通用协议。
+
+### 4.2 Agent 管控面插件
+
+管理插件是 v2 control plane 的产品化管理层：
+
+- 展示 runtime、agent、task、进度、失败、审计。
+- 提供策略配置，例如默认 runtime、provider 偏好、并发限制、重试策略。
+- 触发 runtime 测试、任务取消、任务重试、手动分配。
+
+管理插件不应把 runtime/task 的事实源放进自己的 plugin storage。它应该调用 Host v2 API。
+
+### 4.3 Runtime daemon / worker
+
+Runtime daemon 负责真实执行：
+
+- 在所在机器上检测 CLI 和版本。
+- 管理工作目录、仓库、挂载、临时文件和进程。
+- 从 Host claim 任务，执行后上报 progress / complete / fail。
+- 将 stdout / stderr / artifacts / session id 回流 Host。
+
+Claude Code、Codex、OpenCode、Gemini CLI 等 provider 适配逻辑应主要落在 daemon / worker 或 provider adapter 中。
+
+## 5. 部署形态
+
+### 5.1 uv / local embedded
+
+用户用 `uv` 或源码直接启动 LangBot 时，LangBot 进程所在机器就是 runtime host。
+
+这种模式下可以直接检测用户主机上的 `claude`、`codex` 等 CLI，也可以直接 subprocess 执行。它适合个人开发和本地 smoke，但不应作为团队级管控面的唯一形态。
+
+### 5.2 Docker embedded
+
+用户用 Docker 启动 LangBot 时，runtime host 是容器，不是宿主机。
+
+因此：
+
+- 只能检测容器内的 `claude`、`codex`。
+- 只能使用容器内的 HOME、PATH、凭据和挂载目录。
+- 如果镜像未安装 CLI，或未挂载认证文件 / workspace，CLI runner 会不可用。
+
+Docker embedded 可以作为高级部署选项，但需要用户显式安装 CLI、挂载工作区和凭据。Host 不应假设 Docker 容器能自动访问宿主机 CLI。
+
+### 5.3 Sidecar daemon
+
+推荐的 v2 形态是 sidecar daemon：
+
+```text
+LangBot Host (Docker or server)
+  <-> Runtime daemon on user host / worker host
+        -> claude / codex / other CLI
+```
+
+这种模式下，LangBot 可以跑在 Docker 内，runtime daemon 跑在宿主机或独立 worker 机器上。daemon 负责检测本机 CLI、持有本机凭据和工作区访问能力。
+
+### 5.4 Remote runtime
+
+团队场景可以使用远端 runtime：
+
+- 开发机、构建机、云主机或专用 worker。
+- 多个 workspace 可绑定不同 runtime。
+- Host 只通过 registry / task queue / heartbeat / audit 进行管理。
+
+### 5.5 API-only agent
+
+Dify、n8n、Coze、DashScope 等 API 型 runner 不依赖本地 CLI。它们可以继续按 v1 直接执行，也可以在未来按需要接入 v2 task/audit。
+
+## 6. 与 Claude Code / Codex MVP runner 的关系
+
+当前 Claude Code / Codex runner 是 v1 runner：
+
+```text
+runner.run(ctx) -> subprocess("claude" / "codex")
+```
+
+它们适合验证 Host context 投影、state resume、result stream 和基础 CLI 调用，但有明确限制：
+
+- 命令只在 LangBot runtime host 上执行。
+- Docker 环境只能看到容器内 CLI。
+- 没有 runtime registry、heartbeat、task queue、cancel、workspace lifecycle。
+- 不提供发布级执行隔离、secret projection、团队级 audit。
+
+v2 不需要删除这些 runner。它们可以继续作为 dev / MVP 路径存在。未来若接入管控面，可以增加 runtime-managed 执行模式：
+
+```text
+runner binding -> Host task -> runtime daemon -> provider CLI -> Host result
+```
+
+## 7. 最小 v2 API 草案
+
+以下仅记录能力边界，不代表最终 API 命名。
+
+Runtime：
+
+- `runtime.register`
+- `runtime.heartbeat`
+- `runtime.list`
+- `runtime.get`
+- `runtime.disable`
+- `runtime.capabilities.report`
+- `runtime.capabilities.probe`
+
+Task：
+
+- `task.enqueue`
+- `task.claim`
+- `task.start`
+- `task.progress`
+- `task.complete`
+- `task.fail`
+- `task.cancel`
+- `task.retry`
+
+Workspace：
+
+- `runtime.workspace.bind`
+- `runtime.workspace.unbind`
+- `runtime.workspace.resolve`
+
+Audit / artifacts：
+
+- `task.log.append`
+- `task.artifact.create`
+- `task.events.page`
+
+这些 API 应由 Host 提供，并受 workspace、runtime、binding、actor 和 plugin identity 约束。
+
+## 8. 管控面插件可以构建的能力
+
+基于 v2 Host 能力，可以实现一个类似 Multica 的 agent 管控面插件：
+
+- runtime 列表、在线状态、CLI 能力、版本、认证状态。
+- agent profile 与 runtime/provider 绑定。
+- 任务看板、任务详情、进度流、失败原因、重试和取消。
+- workspace 到 runtime 目录 / 仓库的映射管理。
+- provider capability 测试，例如 Claude Code / Codex 是否可执行。
+- 审计视图：输入、输出、工具、artifact、stdout/stderr、session id。
+- 策略配置：并发、队列、默认 runtime、fallback runtime、权限模式。
+
+该插件应该是 Host v2 的消费者，而不是 Host v2 的替代品。
+
+## 9. 设计原则
+
+- v1 先稳定，v2 可选叠加。
+- Host 保存事实源，插件提供管理体验。
+- Runtime daemon 执行具体 CLI 和本机资源访问。
+- Docker 不假设拥有宿主机 CLI；需要 sidecar 或显式挂载。
+- Pipeline 不进入 v2 控制面中心。
+- 直接 subprocess runner 可保留，但只作为 local/dev/MVP 路径。
+- 发布级能力必须经过 Host 权限、审计和资源边界。
+
+## 10. 待定问题
+
+- runtime daemon 与 Host 的认证模型：workspace token、device token、还是 scoped PAT。
+- task 与 AgentRunner binding 的映射关系：由 binding 直接 enqueue，还是由独立 task policy 决定。
+- runtime capability schema 的稳定字段：provider、version、login status、execution isolation、workspace access、slot。
+- secret projection 的边界：Host 存储、用户本机存储、或外部 secret manager。
+- Docker compose 是否提供官方 sidecar daemon 示例。
+- v2 UI 是核心前端的一部分，还是完全由管理插件提供。

+# Agent Runner Security Hardening
+
+本文档记录 agent-runner 插件化进入生产发布前需要补齐的安全与稳定加固项。
+
+## 状态
+
+**当前结论：暂不塞进本阶段 agent-runner plugin 协议闭环。**
+
+本阶段目标是验证 LangBot 可以通过统一的 `run(event, binding)` 协议接入 `local-agent` 与外部 harness runner（如 Claude Code runner），并能传递事件、上下文、资源句柄、状态和结果流。
+
+安全发布级 hardening 是后续 release gate，不应阻塞当前协议闭环，但必须作为进入生产默认启用前的验收条件。
+
+## 责任边界
+
+### LangBot Host 负责
+
+- 资源授权：决定某个 `run_id` / binding 可以访问哪些模型、RAG、MCP、skill、artifact、history、state。
+- 资源投影：只把授权后的资源句柄、配置片段或上下文文件传给 runner。
+- 路径策略：限制 workspace / context file / artifact 的允许路径和清理策略。
+- Secret 策略：过滤环境变量、配置、日志和 transcript 中的 secret。
+- 运行约束：配置超时、轮次、并发、配额、输出大小和取消路径。
+- 审计记录：记录事件、绑定、资源授权、runner 调用、外部 harness session id、关键错误和结果摘要。
+
+### Runner Plugin 负责
+
+- 遵守 LangBot 下发的 binding config、授权资源和运行约束。
+- 将 LangBot 资源投影成目标 runner 可消费的形式，例如 context 文件、MCP 配置、环境变量或 CLI 参数。
+- 不把长期状态保存在插件实例内；需要跨轮次保存的外部 session id / working directory 等状态应写入 host-owned state。
+- 对外部进程做最小必要封装，包括命令参数构造、超时、取消、输出解析和错误映射。
+
+### 外部 Harness 负责
+
+Claude Code、Codex、Kimi Code 等外部 harness 可以继续使用自身的权限模型、工具 allow / deny 规则、MCP 加载策略、session/resume 机制和沙箱能力。
+
+但外部 harness 不是 LangBot 的唯一安全边界。LangBot 仍必须在调用前完成资源授权、路径限制、secret 过滤和审计记录。
+
+## 当前 MVP 可接受边界
+
+当前阶段可以接受以下前提：
+
+- 由可信管理员配置 runner binding。
+- 工作目录和 context 输出目录为显式配置或 host 生成路径。
+- 外部 runner 默认使用保守权限，例如 plan / no-write 模式或禁用高风险工具。
+- 通过 timeout、max turns、输出长度和进程取消降低失控风险。
+- 通过 host-owned state 保存 `external.session_id`、`external.working_directory` 等 resume 所需指针。
+
+这些前提足够做本地 E2E 与协议验收，不等同于生产发布完成。
+
+## Release Gate Checklist
+
+进入生产默认启用前，需要补齐：
+
+- Path isolation：workspace allowlist、路径规范化、防止 `..` 逃逸、context / artifact 清理。
+- Permission boundary：runner 能力声明、binding 级资源授权、run 级权限校验。
+- Secret handling：环境变量白名单、配置脱敏、日志和 transcript redaction。
+- MCP policy：MCP server allowlist、scoped token、tool allow / deny、危险工具审计。
+- Skill projection policy：skill 来源验证、只读投影、版本和摘要记录。
+- Process isolation：进程组管理、取消、超时、CPU / 内存 / 输出配额。
+- State lifecycle：session id、workspace、artifact 的过期、清理、迁移和审计。
+- Audit first-class：事件、资源授权、外部命令、session id、结果摘要可追踪。
+- UI / Admin control：管理员能看到 runner 权限、风险提示、资源绑定和禁用入口。
+- Test matrix：路径逃逸、secret 泄漏、权限拒绝、timeout、取消、MCP deny、resume、cleanup、audit 完整性。
+
+## 非当前范围
+
+以下内容不属于本阶段协议闭环：
+
+- 完整异步队列与 issue-centric 产品模型。
+- 复杂 workflow engine。
+- Codex / Kimi runner 全量接入。
+- EBA 分支完整迁移和联调。
+- 发布级安全 hardening 的完整实现。
