In practice, most batches contain 1-2 tools, so the impact is minimal. The benefit of being able to interrupt outweighs the cost. + +### Why skip remaining tools (instead of letting them finish) + +Two strategies were considered when a steering message is detected mid-batch: + +1. **Skip remaining tools** (chosen) — stop executing, mark the rest as skipped, inject steering +2. **Finish all tools, then inject** — let everything run, append steering afterwards + +Strategy 2 was rejected for three reasons: + +**Irreversible side effects.** Tools can send emails, write files, spawn subagents, or call external APIs. If the user says "stop" or "change direction", those actions have already happened and cannot be undone. + +| Tool batch | Steering | Skip (1) | Finish (2) | +|---|---|---|---| +| `[search, send_email]` | "don't send it" | Email not sent | Email sent | +| `[query, write_file, spawn]` | "wrong database" | Only query runs | File + subagent wasted | +| `[fetch₁, fetch₂, fetch₃, write]` | topic change | 1 fetch | 3 fetches + write, all discarded | + +**Wasted latency.** Tools like web fetches and API calls take seconds each. In a 3-tool batch averaging 3-4s per tool, the user would wait 10+ seconds for work that gets thrown away. + +**The LLM retains full awareness.** Skipped tools receive an explicit `"Skipped due to queued user message."` result, so the model knows what was not done and can decide whether to re-execute with the new context or take a different path. + +## The Continue() method + +`Continue` handles the case where the agent is **idle** (its last message was from the assistant) and the user has enqueued steering messages in the meantime. + +```mermaid +flowchart TD + A[Continue called] --> B{dequeueSteeringMessages} + B -->|empty| C["return ('', nil)"] + B -->|messages found| D[Combine message contents] + D --> E["runAgentLoop with

Without this flag, `runLLMIteration` would poll again at the start and find nothing (the queue is already empty), or worse, double-process if new messages arrived in the meantime. + +## Configuration + +```json +{ + "agents": { + "defaults": { + "steering_mode": "one-at-a-time" + } + } +} +``` + +| Field | Type | Default | Env var | +|-------|------|---------|---------| +| `steering_mode` | `string` | `"one-at-a-time"` | `PICOCLAW_AGENTS_DEFAULTS_STEERING_MODE` | + + +## Design decisions and trade-offs + +| Decision | Rationale | +|----------|-----------| +| Sequential tool execution | Required for per-tool steering polls. Parallel execution cannot be interrupted mid-batch. | +| Polling-based (not channel/signal) | Keeps the implementation simple. No need for `select` or signal channels. The polling cost is negligible (mutex lock + slice length check). | +| `one-at-a-time` as default | Gives the model a chance to react to each steering message individually. More predictable behavior than dumping all messages at once. | +| Skipped tools get explicit error results | The LLM protocol requires a tool result for every tool call in the assistant message. Omitting them would cause API errors. The skip message also informs the model about what was not done. | +| `Continue()` uses `SkipInitialSteeringPoll` | Prevents race conditions and double-dequeuing when resuming an idle agent. | +| Queue stored on `AgentLoop`, not `AgentInstance` | Steering is a loop-level concern (it affects the iteration flow), not a per-agent concern. All agents share the same steering queue since `processMessage` is sequential. | +| Bus drain goroutine in `Run()` | Channels (Telegram, Discord, etc.) publish to the bus via `PublishInbound`. Without the drain, messages would queue in the bus channel buffer and only be consumed after `processMessage` returns — defeating the purpose of steering. The drain goroutine bridges the gap by consuming new bus messages and calling `Steer()` while the agent is busy. | +| Audio transcription before steering | The drain goroutine calls `al.transcribeAudioInMessage(ctx, msg)` before steering, so voice messages are converted to text before the agent sees them. If transcription fails, the error is silently discarded and the original message is steered as-is. | +| `MaxQueueSize = 10` | Prevents unbounded memory growth if a user sends many messages while the agent is busy. Excess messages are dropped with a warning. | diff --git a/docs/steering.md b/docs/steering.md new file mode 100644 index 0000000000..ad08f84250 --- /dev/null +++ b/docs/steering.md @@ -0,0 +1,166 @@ +# Steering + +Steering allows injecting messages into an already-running agent loop, interrupting it between tool calls without waiting for the entire cycle to complete. + +## How it works + +When the agent is executing a sequence of tool calls (e.g. the model requested 3 tools in a single turn), steering checks the queue **after each tool** completes.

Changes: - Add context_window field to AgentDefaults config (default: 4x max_tokens) - Extract boundary-safe truncation helpers (isSafeBoundary, findSafeBoundary) into context_budget.go — pure functions with no AgentLoop dependency - forceCompression: align split to safe boundary so tool-call sequences (assistant+ToolCalls → tool results) are never torn apart - summarizeSession: use findSafeBoundary instead of hardcoded keep-last-4 - estimateTokens: count ToolCalls arguments and ToolCallID metadata, not just Content — fixes systematic undercounting in tool-heavy sessions - Add proactive context budget check before LLM call in runAgentLoop, preventing 400 context-length errors instead of reacting to them - Add estimateToolDefsTokens for tool definition token cost Closes #556, closes #665 Ref #1439 --- pkg/agent/context_budget.go | 133 ++++++++ pkg/agent/context_budget_test.go | 545 +++++++++++++++++++++++++++++++ pkg/agent/instance.go | 13 +- pkg/agent/loop.go | 49 ++- pkg/config/config.go | 1 + 5 files changed, 727 insertions(+), 14 deletions(-) create mode 100644 pkg/agent/context_budget.go create mode 100644 pkg/agent/context_budget_test.go diff --git a/pkg/agent/context_budget.go b/pkg/agent/context_budget.go new file mode 100644 index 0000000000..2eec9c2673 --- /dev/null +++ b/pkg/agent/context_budget.go @@ -0,0 +1,133 @@ +// PicoClaw - Ultra-lightweight personal AI agent +// License: MIT +// +// Copyright (c) 2026 PicoClaw contributors + +package agent + +import ( + "encoding/json" + "unicode/utf8" + + "github.com/sipeed/picoclaw/pkg/providers" +) + +// isSafeBoundary reports whether index is a valid position to split a message +// history for truncation or compression.

If over budget, triggers `forceCompression` and rebuilds messages before calling the LLM. + +This prevents wasted (and billed) LLM calls that would otherwise fail with a context-window error. + +### 3. Emergency compression (reactive) + +`forceCompression` runs when the LLM returns a context-window error despite the proactive check. + +Drops the oldest ~50% of Turns. Stores a compression note in the session summary (not in history messages) so `BuildMessages` can include it in the next system prompt. + +This is the fallback for when the token estimate undershoots reality. + +--- + +## Token estimation + +Estimation uses a heuristic of ~2.5 characters per token (`chars * 2 / 5`). + +`estimateMessageTokens` counts: + +- `Content` (rune count, for multibyte correctness) +- `ReasoningContent` (extended thinking / chain-of-thought) +- `ToolCalls` — ID, type, function name, arguments +- `ToolCallID` (tool result metadata) +- Per-message overhead (role label, JSON structure) +- `Media` items — flat per-item token estimate, added directly to the final count (not through the character heuristic, since actual cost depends on resolution and provider-specific image tokenization) + +`estimateToolDefsTokens` counts tool definition overhead: name, description, JSON schema of parameters. + +These are deliberately heuristic.

Fix turnState hierarchy corruption in nested SubTurns by checking context before creating new root turnState in runAgentLoop - Fix deadlock risk in deliverSubTurnResult by separating lock and channel ops - Fix session rollback race in HardAbort by calling Finish() before rollback - Fix resource leak by closing pendingResults channel in Finish() with recovery - Add thread-safety docs for childTurnIDs and isFinished fields Medium priority fixes (5): - Move globalTurnCounter to AgentLoop.subTurnCounter to prevent ID conflicts - Improve semaphore acquisition to ensure release even on early validation failures - Document design choice: ephemeral sessions start empty for complete isolation - Add final poll before Finish() to capture late-arriving SubTurn results - Remove duplicate channel registration in spawnSubTurn to fix timing issues Testing: - Add 6 new tests covering hierarchy, deadlock, ordering, channel lifecycle, final poll, and semaphore behavior -

turnStateKeyType and context key management - turnState struct definition - TurnInfo struct and GetActiveTurn() method - newTurnState(), Finish(), and drainPendingResults() methods - ephemeralSessionStore implementation - All context helper functions (withTurnState, TurnStateFromContext, etc.) Updated /pkg/agent/subturn.go (428 lines) by: - Removing the moved turnState struct and methods - Removing unused imports (sync, session) - Keeping SubTurn spawning logic, config, events, and result delivery All tests pass and the code compiles successfully. --- pkg/agent/subturn.go | 229 ------------------------------------- pkg/agent/turn_state.go | 246 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 246 insertions(+), 229 deletions(-) create mode 100644 pkg/agent/turn_state.go diff --git a/pkg/agent/subturn.go b/pkg/agent/subturn.go index d6b9ec90c7..a3a3f15d21 100644 --- a/pkg/agent/subturn.go +++ b/pkg/agent/subturn.go @@ -4,12 +4,10 @@ import ( "context" "errors" "fmt" -

Solution: Implement a lifecycle management system that distinguishes between: - Graceful finish (Finish(false)): signals parentEnded, children continue - Hard abort (Finish(true)): immediately cancels all children Changes: - turn_state.go: - Add parentEnded atomic.Bool to signal parent completion - Add parentTurnState reference for IsParentEnded() checks - Modify Finish(isHardAbort bool) to distinguish abort types - subturn.go: - Add Critical bool to SubTurnConfig (Critical SubTurns continue after parent ends) - Add Timeout time.Duration for SubTurn self-protection - Use independent context (context.Background()) instead of derived context - SubTurns check IsParentEnded() to decide whether to continue or exit - loop.go: - Call Finish(false) for normal completion (graceful) - Add IsParentEnded() check in LLM iteration loop - steering.go: - HardAbort calls Finish(true) to immediately cancel children Behavior: - Normal finish: parentEnded=true, children continue, orphan results delivered - Hard abort: all children cancelled immediately via context - Critical SubTurns: continue running after parent finishes gracefully - Non-Critical SubTurns: can exit gracefully when IsParentEnded() returns true --- pkg/agent/loop.go | 21 ++++- pkg/agent/steering.go | 3 +- pkg/agent/subturn.go | 65 +++++++------ pkg/agent/subturn_test.go | 190 ++++++++++++++++++++++++++++++++++---- pkg/agent/turn_state.go | 67 +++++++++++--- 5 files changed, 284 insertions(+), 62 deletions(-) diff --git a/pkg/agent/loop.go b/pkg/agent/loop.go index 5a2a51a7b1..b4a7774c3b 100644 --- a/pkg/agent/loop.go +++ b/pkg/agent/loop.go @@ -1073,10 +1073,12 @@ func (al *AgentLoop) runAgentLoop( } } - // Signal completion to rootTS so it knows it is finished, terminating any active sub-turns. + // Signal completion to rootTS so it knows it is finished. // Only call Finish() if this is a root turn (not a SubTurn recursively calling runAgentLoop). + // Use isHardAbort=false for normal completion (graceful finish). + // This allows Critical SubTurns to continue running and deliver orphan results. if isRootTurn { - rootTS.Finish() + rootTS.Finish(false) } // If last tool had ForUser content and we already sent it, we might not need to send final response @@ -1211,6 +1213,21 @@ func (al *AgentLoop) runLLMIteration( for iteration < agent.MaxIterations || len(pendingMessages) > 0 { iteration++ + // Check if parent turn has ended (graceful finish). + // This is only relevant for SubTurns (turnState with parentTurnState != nil). + // If parent ended and this SubTurn is not Critical, exit gracefully. + if ts := turnStateFromContext(ctx); ts != nil && ts.IsParentEnded() { + logger.InfoCF("agent", "Parent turn ended, SubTurn continues or exits", map[string]any{ + "agent_id": agent.ID, + "iteration": iteration, + "turn_id": ts.turnID, + }) + // For now, we continue running.

From c7ea018a73dae733017ab71a0389c86c6e17725b Mon Sep 17 00:00:00 2001 From: Administrator <1280842908@qq.com> Date: Wed, 18 Mar 2026 12:18:32 +0800 Subject: [PATCH 28/60] fix(agent): prevent duplicate history during subturn context recoveries Problem: During subturn context limit or truncation recoveries, the recovery loops repeatedly called `runAgentLoop` with the same or modified `UserMessage`. Because `runAgentLoop` unconditionally adds the `UserMessage` to the session history, this resulted in: 1. Duplicate User Messages polluting the history upon `context_length_exceeded` retries. 2. The possibility of injecting empty User Messages if `opts.UserMessage` was artificially blanked out to work around the duplication. 3. Messy or duplicate entries during `finish_reason="truncated"` recovery injections. Solution: - Introduce `SkipAddUserMessage` boolean to `processOptions` to explicitly control whether the agent loop should write the user prompt to history. - Add an explicit `opts.UserMessage != ""` check in `runAgentLoop` to prevent polluting history with empty message content. - In `subturn.go`'s recovery loop, set `SkipAddUserMessage: contextRetryCount > 0` to skip writing the user message on context --- pkg/agent/loop.go | 14 +- pkg/agent/subturn.go | 181 ++++++++++++- pkg/agent/turn_state.go | 19 ++ pkg/providers/common/common.go | 11 +- pkg/utils/context.go | 173 +++++++++++++ pkg/utils/context_test.go | 450 +++++++++++++++++++++++++++++++++ 6 files changed, 834 insertions(+), 14 deletions(-) create mode 100644 pkg/utils/context.go create mode 100644 pkg/utils/context_test.go diff --git a/pkg/agent/loop.go b/pkg/agent/loop.go index b4a7774c3b..d9f9e63718 100644 --- a/pkg/agent/loop.go +++ b/pkg/agent/loop.go @@ -49,8 +49,8 @@ type AgentLoop struct { cmdRegistry *commands.Registry mcp mcpRuntime steering *steeringQueue - subTurnResults sync.Map // key: sessionKey (string), value: chan *tools.ToolResult - activeTurnStates sync.Map // key: sessionKey (string), value: *turnState + subTurnResults sync.Map // key: sessionKey (string), value: chan *tools.ToolResult + activeTurnStates sync.Map // key: sessionKey (string), value: *turnState subTurnCounter atomic.Int64 // Counter for generating unique SubTurn IDs mu sync.RWMutex // Track active requests for safe provider cleanup @@ -69,6 +69,7 @@ type processOptions struct { SendResponse bool // Whether to send response via bus NoHistory bool // If true, don't load session history (for heartbeat) SkipInitialSteeringPoll bool // If true, skip the steering poll at loop start (used by Continue) + SkipAddUserMessage bool // If true, skip adding UserMessage to session history } const ( @@ -1051,7 +1052,9 @@ func (al *AgentLoop) runAgentLoop( messages = resolveMediaRefs(messages, al.mediaStore, maxMediaSize) // 2.

Fix Goroutine Leak & Deadlock in deliverSubTurnResult: - Replaced non-blocking select with a safe blocking select that listens to `resultChan` and a new `<-parentTS.Finished()` channel. - This ensures results are not arbitrarily dropped when the channel is full (preventing orphaned valid results), while also guaranteeing the child goroutine safely unblocks and exits if the parent finishes execution early. 2. Prevent "Send on Closed Channel" Fatal Panics: - Removed `close(pendingResults)` and `drainPendingResults` from `turnState.Finish()`. - The pendingResults channel is now naturally garbage collected, completely eliminating the race condition panic when a child attempts delivery at the exact moment the parent finishes. - Added a `defer recover()` failsafe inside deliverSubTurnResult to gracefully emit Orphan events in extreme edge cases. 3. Fix Truncation Recovery Prompt Drop: - Fixed the runTurn truncation retry logic by introducing an explicit `promptAlreadyAdded` boolean. - Ensures that the dynamically generated `recoveryPrompt` is correctly injected into the LLM history sequence on subsequent iterations, adhering to API roles without duplicating arrays. 4. Test Suite Stabilization: - Fixed TestDeliverSubTurnResultNoDeadlock to accurately wait for deterministic deliveries instead of racing timeouts. - Replaced defunct closed-channel tests with TestFinishedChannelClosedState matching the new Finished() mechanism. - Fixed the Finish(true) parameter in TestGrandchildAbort_CascadingCancellation to correctly validate Context cascade behavior. - All tests now pass cleanly without hanging or emitting false positives. --- pkg/agent/subturn.go | 39 ++++++-- pkg/agent/subturn_test.go | 182 ++++++-------------------------------- pkg/agent/turn_state.go | 63 +++++++------ 3 files changed, 94 insertions(+), 190 deletions(-) diff --git a/pkg/agent/subturn.go b/pkg/agent/subturn.go index 3c178d9fc8..7a9cb3304a 100644 --- a/pkg/agent/subturn.go +++ b/pkg/agent/subturn.go @@ -344,7 +344,24 @@ func spawnSubTurn(ctx context.Context, al *AgentLoop, parentTS *turnState, cfg S // - SubTurnResultDeliveredEvent: successful delivery to channel // - SubTurnOrphanResultEvent: delivery failed (parent finished or channel full) func deliverSubTurnResult(parentTS *turnState, childID string, result *tools.ToolResult) { - // Check parent state under lock, but don't hold lock while sending to channel + // Let GC clean up the pendingResults channel; parent Finish will no longer close it. + // We use defer/recover to catch any unlikely channel panics if it were ever closed. + defer func() { + if r := recover(); r != nil { + logger.WarnCF("subturn", "recovered panic sending to pendingResults", map[string]any{ + "parent_id": parentTS.turnID, + "child_id": childID, + "recover": r, + }) + if result != nil { + MockEventBus.Emit(SubTurnOrphanResultEvent{ + ParentID: parentTS.turnID, + ChildID: childID, + Result: result, + }) + } + } + }() parentTS.mu.Lock() isFinished := parentTS.isFinished resultChan := parentTS.pendingResults @@ -363,8 +380,9 @@ func deliverSubTurnResult(parentTS *turnState, childID string, result *tools.Too } // Parent Turn is still running → attempt to deliver result - // Note: There's still a small race window between the isFinished check above and the send below, - // but this is acceptable - worst case the result becomes an orphan, which is handled gracefully. + // We use a select statement with parentTS.Finished() to ensure that if the + // parent turn finishes while we are waiting to send the result (e.g. channel + // is full), we don't leak this goroutine by blocking forever. select { case resultChan <- result: // Successfully delivered @@ -373,9 +391,10 @@ func deliverSubTurnResult(parentTS *turnState, childID string, result *tools.Too ChildID: childID, Result: result, }) - default: - // Channel is full - treat as orphan result - logger.WarnCF("subturn", "pendingResults channel full", map[string]any{ + case <-parentTS.Finished(): + // Parent finished while we were waiting to deliver. + // The result cannot be delivered to the LLM, so it becomes an orphan. + logger.WarnCF("subturn", "parent finished before result could be delivered", map[string]any{ "parent_id": parentTS.turnID, "child_id": childID, }) @@ -474,6 +493,7 @@ func runTurn(ctx context.Context, al *AgentLoop, ts *turnState, cfg SubTurnConfi truncationRetryCount := 0 contextRetryCount := 0 currentPrompt := cfg.SystemPrompt + promptAlreadyAdded := false for { // Soft context limit: check and truncate before LLM call @@ -512,9 +532,13 @@ func runTurn(ctx context.Context, al *AgentLoop, ts *turnState, cfg SubTurnConfi DefaultResponse: "", EnableSummary: false, SendResponse: false, - SkipAddUserMessage: contextRetryCount > 0, + SkipAddUserMessage: promptAlreadyAdded, }) + // Mark the prompt as added so subsequent truncation retries + // won't duplicate it in the history. + promptAlreadyAdded = true + // 1.

"review-gate": { + "enabled": true, + "transport": "stdio", + "command": ["uvx", "picoclaw-hook-reviewer"], + "observe": ["turn_start", "turn_end", "tool_exec_end"], + "intercept": ["before_tool", "approve_tool"], + "timeout_ms": 5000 + } + } + } +} +``` + +### 协议边界 + +不要把内部 Go 结构体直接暴露给 IPC。 + +建议定义稳定的协议对象： + +- `HookHandshake` +- `HookEventNotification` +- `BeforeLLMRequest` +- `AfterLLMRequest` +- `BeforeToolRequest` +- `AfterToolRequest` +- `ApproveToolRequest` +- `HookDecision` + +其中： + +- 观察型事件用 notification，fire-and-forget +- 拦截型事件用 request/response，同步等待 + +### 为什么是 stdio，而不是直接用 HTTP webhook + +因为两者用途不同： + +- HTTP webhook 更适合“外部系统向 PicoClaw 投递事件” +- stdio/RPC 更适合“PicoClaw 在 turn 内同步询问外部 hook 是否改写 / 放行 / 拒绝” + +如果未来需要 OpenClaw 式 webhook，可以作为独立入口层，再把外部事件转成 inbound message 或 steering，而不是直接替代 hook IPC。 + +## Hook 执行顺序 + +建议统一排序规则： + +- 先内建 in-process hook +- 再外部 IPC hook +- 同组内按 `priority` 从小到大执行 + +原因： + +- 内建 hook 延迟更低，适合做基础规范化 +- 外部 hook 更适合做审批、审计、组织级策略 + +## 超时与错误策略 + +### 观察型 + +- 默认超时：`500ms` +- 超时或报错：记录日志，继续主流程 + +### 拦截型 + +- `before_llm` / `after_llm` / `before_tool` / `after_tool`：默认 `5s` +- `approve_tool`：默认 `60s` + +超时行为： + +- 普通拦截：`continue` +- 审批：`deny` + +这点应直接沿用 `#1316` 的安全倾向。 + +## 与当前分支的对接点 + +### 直接复用 + +- 事件定义：`pkg/agent/events.go` +- 事件广播：`pkg/agent/eventbus.go` +- 活跃 turn / interrupt / rollback：`pkg/agent/turn.go` +-

`pkg/agent/hook_ipc.go` + - stdio JSON-RPC bridge + +- `pkg/agent/hook_types.go` + - IPC 稳定载荷 + +### 需要改造 + +- `pkg/agent/loop.go` + - 在 LLM 和 tool 关键路径前后插入 HookManager 调用 + +- `pkg/tools/base.go` + - 可选新增 `ReadOnlyIndicator` + +- `pkg/tools/spawn.go` +- `pkg/tools/subagent.go` + - 先保留现状 + - 等 sub-turn 迁移后再接入 `subturn_*` hook + +## 一个更贴合当前分支的数据流 + +### 观察链路 + +```text +runTurn() -> emitEvent() ->

+ -> tool.Execute() + -> HookManager.AfterTool() +``` + +也就是说： + +- observer 不改变现有 `emitEvent()` +- interceptor 直接插在 `runTurn()` 热路径 + +## 用户可见配置 + +建议新增： + +```json +{ + "hooks": { + "enabled": true, + "builtins": {}, + "processes": {}, + "defaults": { + "observer_timeout_ms": 500, + "interceptor_timeout_ms": 5000, + "approval_timeout_ms": 60000 + } + } +} +``` + +V1 不做复杂自动发现。 + +原因： + +- 当前分支重点是把地基打稳 +- 目录扫描、安装器、脚手架可以后置 +- 先让仓内和仓外都能挂上去，比“管理体验完整”更重要 + +## 推荐的 V1 范围 + +### 必做 + +- HookManager +- in-process 挂载 +- stdio IPC 挂载 +- observer hooks +- `before_tool` / `after_tool` / `approve_tool` +- `before_llm` / `after_llm` + +### 可后置 + +- hook CLI 管理命令 +- hook 自动发现 +- Unix socket / named pipe transport +- sub-turn hook 生命周期 +- read-only 并行分组 +- webhook 到 inbound message 的映射入口 + +## 分阶段落地 + +### Phase 1 + +- 引入 HookManager +- 支持 in-process observer + interceptor +- 先只接主 turn + +### Phase 2 + +- 引入 `stdio` 外部 hook 进程桥 +- 支持组织级审批 / 审计 / 参数改写 + +### Phase 3 + +- 把 `SubagentManager` 迁移到 `runTurn/sub-turn` +- 接通 `subturn_spawn` / `subturn_end` / `subturn_result_delivered` + +### Phase 4 + +- 视需求补 `ReadOnlyIndicator` +- 在主 turn 和 sub-turn 上统一只读并行策略 + +## 最终结论 + +最适合 PicoClaw 当前分支的方案，不是直接复制 OpenClaw 的 hooks，也不是完整照搬 pi-mono 的 extension system，而是： + +- 以现有 `EventBus` 为只读观察面 +- 以新增 `HookManager` 为同步拦截面 +- 项目内通过 Go 对象直接挂载 +- 项目外通过 `stdio JSON-RPC` 进程通信挂载 + +这样做有三个好处： + +- 和 `#1796` 一致，hooks 只是 EventBus 之上的消费层 +- 和当前 `refactor/agent` 实现一致，不需要推翻已有事件系统 +- 同时满足“仓内简单挂载”和“仓外进程通信挂载”两个硬需求 diff --git a/pkg/agent/hooks.go b/pkg/agent/hooks.go new file mode 100644

`hook.before_llm` / `hook.after_llm` / `hook.before_tool` / `hook.after_tool` / `hook.approve_tool` 是 request/response + +当前宿主不会接受 process hook 主动发起的新 RPC。也就是说，外部 hook 现在只能“响应 PicoClaw

路径是否正确 +4. 你看的是否是正确的日志文件 +5. 当前请求是否真的走到了对应阶段 +6. `observe` / `intercept` 是否包含了你想看的点位 + +一个很实用的最小排查组合是： + +- 先用文档里的 Python process 示例确认外部协议没问题 +- 再用文档里的 Go in-process 示例确认宿主内的 hook 链路没问题 + +如果前者有 `hook.hello` 但没有业务请求，通常不是协议挂了，而是当前这次请求没有真正触发对应的 hook 点位。 + +## 适用边界 + +当前 hook 系统最适合做这些事： + +- LLM 请求改写 +- 工具参数规范化 +- 工具执行前审批 +- 审计和观测 + +当前还不适合直接承载这些需求： + +- 外部 hook 主动发 channel 消息 +- 挂起 turn 并等待人工审批回复 +- inbound/outbound 全链路消息拦截 + +如果你要做人审流转，推荐把 hook 作为审批入口，把审批状态机和 channel 交互放到独立的 `ApprovalManager`。 From 482c88cd15a6b79e839e50c1ca69c997b4a779f8 Mon Sep 17 00:00:00 2001 From: Administrator

If over budget, triggers `forceCompression` and rebuilds messages before calling the LLM. + +This prevents wasted (and billed) LLM calls that would otherwise fail with a context-window error. + +### 3. Emergency compression (reactive) + +`forceCompression` runs when the LLM returns a context-window error despite the proactive check. + +Drops the oldest ~50% of Turns. If the history is a single Turn with no safe split point (e.g. one user message followed by a massive tool response), falls back to keeping only the most recent user message — breaking Turn atomicity as a last resort to avoid a context-exceeded loop. + +Stores a compression note in the session summary (not in history messages) so `BuildMessages` can include it in the next system prompt. + +This is the fallback for when the token estimate undershoots reality. + +--- + +## Token estimation + +Estimation uses a heuristic of ~2.5 characters per token (`chars * 2 / 5`). + +`estimateMessageTokens` counts: + +- `Content` (rune count, for multibyte correctness) +- `ReasoningContent` (extended thinking / chain-of-thought) +- `ToolCalls` — ID, type, function name, arguments +- `ToolCallID` (tool result metadata) +- Per-message overhead (role label, JSON structure) +- `Media` items — flat per-item token estimate, added directly to the final count (not through the character heuristic, since actual cost depends on resolution and provider-specific image tokenization) + +`estimateToolDefsTokens` counts tool definition overhead: name, description, JSON schema of parameters. + +These are deliberately heuristic. The proactive check handles the common case; the reactive path catches estimation errors. + +--- + +## Interface boundaries + +Context budget functions (`parseTurnBoundaries`, `findSafeBoundary`, `estimateMessageTokens`, `isOverContextBudget`) are **pure functions**. They take `[]providers.Message` and integer parameters. They have no dependency on `AgentLoop` or any other runtime struct. + +`BuildMessages` is the sole assembler of the final message array sent to the LLM. Budget functions inform compression decisions but do not construct messages. + +`forceCompression` and `summarizeSession` mutate session state (history and summary). `BuildMessages` reads that state to construct context. The flow is: + +``` +budget check --> compression decision --> mutate session --> BuildMessages reads session --> LLM call +``` + +--- + +## Known gaps + +These are recognized limitations in the current implementation, documented here for visibility: + +- **Summarization trigger does not use the full budget formula.** `maybeSummarize` compares estimated history tokens against a percentage of `ContextWindow`. It does not account for system prompt size, tool definition overhead, or `MaxTokens` reserve. The proactive check covers the critical path (preventing 400 errors), but the summarization trigger could be aligned with the same budget model for more accurate early compression. + +- **Token estimation is heuristic.** It does not account for provider-specific tokenization, exact system prompt size (assembled separately), or variable image token costs. The two-path design (proactive + reactive) is intended to tolerate this imprecision. + +- **Reactive retry does not preserve media.** When the reactive path rebuilds context after compression, it currently passes empty values for media references. This is a pre-existing issue in the main loop, not introduced by the budget system. + +--- + +## What this document does not cover + +- How `AGENT.md` frontmatter configures context parameters — that is part of the Agent definition work +- How the context builder assembles context in the new architecture — that is upcoming work +- How compression events surface through the event system — that is part of the event model (#1316) +- Subagent context isolation — that is a separate track diff --git a/docs/design/hook-system-design.zh.md b/docs/design/hook-system-design.zh.md new file mode 100644 index 0000000000..ab5566bec9 --- /dev/null +++ b/docs/design/hook-system-design.zh.md @@ -0,0 +1,476 @@ +# PicoClaw Hook 系统设计（基于 `refactor/agent`） + +## 背景 + +本设计围绕两个议题展开： + +- `#1316`：把 agent loop 重构为事件驱动、可中断、可追加、可观测 +- `#1796`：在 EventBus 稳定后，把 hooks 设计为 EventBus 的 consumer，而不是重新发明一套事件模型 + +当前分支已经完成了第一步里的“事件系统基础”，但还没有真正的 hook 挂载层。因此这里的目标不是重新设计 event，而是在已有实现上补出一层可扩展、可拦截、可外挂的 HookManager。 + +## 外部项目对比 + +### OpenClaw + +OpenClaw 的扩展能力分成三层： + +- Internal hooks：目录发现，运行在 Gateway 进程内 +- Plugin hooks：插件在运行时注册 hook，也在进程内 +- Webhooks：外部系统通过 HTTP 触发 Gateway 动作，属于进程外 + +值得借鉴的点： + +- 有“项目内挂载”和“项目外挂载”两种路径 +- hook 是配置驱动，可启停 +- 外部入口有明确的安全边界和映射层 + +不建议直接照搬的点： + +- OpenClaw 的 hooks / plugin hooks / webhooks 是三套路由，PicoClaw 当前体量下会偏重 +- HTTP webhook 更适合“事件进入系统”，不适合作为“可同步拦截 agent loop”的基础机制 + +### pi-mono + +pi-mono 的核心思路更接近当前分支： + +- 扩展统一为 extension API +- 事件分为观察型和可变更型 +- 某些阶段允许 `transform` / `block` / `replace` +- 扩展代码主要是进程内执行 +- RPC mode 把 UI 交互桥接到进程外客户端 + +值得借鉴的点： + +- 不把“观察”和“拦截”混成一个接口 +- 允许返回结构化动作，而不是只有回调 +- 进程外通信只暴露必要协议，不把整个内部对象图泄露出去 + +## 当前分支现状 + +### 已有能力 + +当前分支已经具备 hook 系统的地基： + +- `pkg/agent/events.go` 定义了稳定的 `EventKind`、`EventMeta` 和 payload +- `pkg/agent/eventbus.go` 提供了非阻塞 fan-out 的 `EventBus` +- `pkg/agent/loop.go` 中的 `runTurn()` 已在 turn、llm、tool、interrupt、follow-up、summary 等节点发射事件 +- `pkg/agent/steering.go` 已支持 steering、graceful interrupt、hard abort +- `pkg/agent/turn.go` 已维护 turn phase、恢复点、active turn、abort 状态 + +### 现有缺口 + +当前分支还缺四件事： + +- 没有 HookManager，只有 EventBus +- 没有 Before/After LLM、Before/After Tool 这种同步拦截点 +- 没有审批型 hook +- 子 agent 仍走 `pkg/tools/SubagentManager + RunToolLoop`，没有接入 `pkg/agent` 的 turn tree 和事件流 + +### 一个关键现实 + +`#1316` 文案里提到“只读并行、写入串行”的工具执行策略，但当前 `runTurn()` 实现已经先收敛成“顺序执行 + 每个工具后检查 steering / interrupt”。因此 hook 设计不应依赖未来的并行模型，而应该先兼容当前顺序执行，再为以后增加 `ReadOnlyIndicator` 留口子。 + +## 设计原则 + +- Hook 必须建立在 `pkg/agent` 的 EventBus 和 turn 上下文之上 +- EventBus 负责广播，HookManager 负责拦截，两者职责分离 +- 项目内挂载要简单，项目外挂载必须走 IPC +- 观察型 hook 不能阻塞 loop；拦截型 hook 必须有超时 +- 先覆盖主 turn，不把 sub-turn 一次做满 +- 不新增第二套用户事件命名系统，优先复用 `EventKind.String()` + +## 总体架构 + +分成三层： + +1. `EventBus` + 负责广播只读事件，现有实现直接复用 + +2. `HookManager` + 负责管理 hook、排序、超时、错误隔离，并在 `runTurn()` 的明确检查点执行同步拦截 + +3. `HookMount` + 负责两种挂载方式： + -

- -### Configuration de Modèle (model_list) - -> **Nouveau !** PicoClaw utilise désormais une approche de configuration **centrée sur le modèle**. Spécifiez simplement le format `fournisseur/modèle` (par exemple, `zhipu/glm-4.7`) pour ajouter de nouveaux fournisseurs—**aucune modification de code requise !** - -Cette conception permet également le **support multi-agent** avec une sélection flexible de fournisseurs : - -- **Différents agents, différents fournisseurs** : Chaque agent peut utiliser son propre fournisseur LLM -- **Modèles de secours (Fallbacks)** : Configurez des modèles primaires et de secours pour la résilience -- **Équilibrage de charge** : Répartissez les requêtes sur plusieurs points de terminaison -- **Configuration centralisée** : Gérez tous les fournisseurs en un seul endroit -

- -## ⚙️ 設定 - -設定ファイル: `~/.picoclaw/config.json` - -### 環境変数 - -環境変数を使用してデフォルトのパスを上書きできます。これは、ポータブルインストール、コンテナ化されたデプロイメント、または picoclaw をシステムサービスとして実行する場合に便利です。これらの変数は独立しており、異なるパスを制御します。 - -| 変数 | 説明 | デフォルトパス | -|-------------------|-----------------------------------------------------------------------------------------------------------------------------------------|---------------------------| -| `PICOCLAW_CONFIG` | 設定ファイルへのパスを上書きします。これにより、picoclaw は他のすべての場所を無視して、指定された `config.json` をロードします。 | `~/.picoclaw/config.json` | -| `PICOCLAW_HOME` | picoclaw データのルートディレクトリを上書きします。これにより、`workspace` やその他のデータディレクトリのデフォルトの場所が変更されます。 | `~/.picoclaw` | - -**例：** - -```bash -# 特定の設定ファイルを使用して picoclaw を実行する -# ワークスペースのパスはその設定ファイル内から読み込まれます -PICOCLAW_CONFIG=/etc/picoclaw/production.json picoclaw gateway - -# すべてのデータを /opt/picoclaw に保存して picoclaw を実行する -# 設定はデフォルトの ~/.picoclaw/config.json からロードされます -# ワークスペースは /opt/picoclaw/workspace に作成されます -PICOCLAW_HOME=/opt/picoclaw picoclaw agent - -# 両方を使用して完全にカスタマイズされたセットアップを行う -PICOCLAW_HOME=/srv/picoclaw PICOCLAW_CONFIG=/srv/picoclaw/main.json picoclaw gateway -``` - -### ワークスペース構成 - -PicoClaw は設定されたワークスペース（デフォルト: `~/.picoclaw/workspace`）にデータを保存します： - -``` -~/.picoclaw/workspace/ -├── sessions/ # 会話セッションと履歴 -├── memory/ # 長期メモリ（MEMORY.md） -├── state/ # 永続状態（最後のチャネルなど） -├── cron/ # スケジュールジョブデータベース -├── skills/ # カスタムスキル -├── AGENT.md # 構造化されたエージェント定義とシステムプロンプト -├── HEARTBEAT.md # 定期タスクプロンプト（30分ごとに確認） -├── SOUL.md # エージェントのソウル -└── ... -``` - -### 🔒 セキュリティサンドボックス - -PicoClaw はデフォルトでサンドボックス環境で実行されます。エージェントは設定されたワークスペース内のファイルにのみアクセスし、コマンドを実行できます。 - -#### デフォルト設定 - -```json -{ - "agents": { - "defaults": { - "workspace": "~/.picoclaw/workspace", - "restrict_to_workspace": true - } - } -} -``` - -| オプション | デフォルト | 説明 | -|-----------|-----------|------| -| `workspace` | `~/.picoclaw/workspace` | エージェントの作業ディレクトリ | -| `restrict_to_workspace` | `true` | ファイル/コマンドアクセスをワークスペースに制限 | - -#### 保護対象ツール - -`restrict_to_workspace: true` の場合、以下のツールがサンドボックス化されます： - -| ツール | 機能 | 制限 | -|-------|------|------| -| `read_file` | ファイル読み込み | ワークスペース内のファイルのみ | -| `write_file` | ファイル書き込み | ワークスペース内のファイルのみ | -| `list_dir` | ディレクトリ一覧 | ワークスペース内のディレクトリのみ | -| `edit_file` | ファイル編集 | ワークスペース内のファイルのみ | -| `append_file` | ファイル追記 | ワークスペース内のファイルのみ | -| `exec` | コマンド実行 | コマンドパスはワークスペース内である必要あり | - -#### exec ツールの追加保護 - -`restrict_to_workspace: false` でも、`exec` ツールは以下の危険なコマンドをブロックします： - -- `rm -rf`, `del /f`, `rmdir /s` — 一括削除 -- `format`, `mkfs`, `diskpart` — ディスクフォーマット -- `dd if=` — ディスクイメージング -- `/dev/sd[a-z]` への書き込み — 直接ディスク書き込み -- `shutdown`, `reboot`, `poweroff` — システムシャットダウン -- フォークボム `:(){ :|:& };:` - -#### エラー例 - -``` -[ERROR] tool: Tool execution failed -{tool=exec, error=Command blocked by safety guard (path outside working dir)} -``` - -``` -[ERROR] tool: Tool execution failed -{tool=exec, error=Command blocked by safety guard (dangerous pattern detected)} -``` - -#### 制限の無効化（セキュリティリスク） - -エージェントにワークスペース外のパスへのアクセスが必要な場合： - -**方法1: 設定ファイル** -```json -{ - "agents": { - "defaults": { - "restrict_to_workspace": false - } - } -} -``` - -**方法2: 環境変数** -```bash -export PICOCLAW_AGENTS_DEFAULTS_RESTRICT_TO_WORKSPACE=false -``` - -> ⚠️ **警告**: この制限を無効にすると、エージェントはシステム上の任意のパスにアクセスできるようになります。制御された環境でのみ慎重に使用してください。 - -#### セキュリティ境界の一貫性 - -`restrict_to_workspace` 設定は、すべての実行パスで一貫して適用されます： - -| 実行パス | セキュリティ境界 | -|---------|-----------------| -| メインエージェント | `restrict_to_workspace` ✅ | -| サブエージェント / Spawn | 同じ制限を継承 ✅ | -| ハートビートタスク | 同じ制限を継承 ✅ | - -すべてのパスで同じワークスペース制限が適用されます — サブエージェントやスケジュールタスクを通じてセキュリティ境界をバイパスする方法はありません。 - -### ハートビート（定期タスク） - -PicoClaw は自動的に定期タスクを実行できます。ワークスペースに `HEARTBEAT.md` ファイルを作成します： - -```markdown -# 定期タスク - -- 重要なメールをチェック -- 今後の予定を確認 -- 天気予報をチェック -``` - -エージェントは30分ごと（設定可能）にこのファイルを読み込み、利用可能なツールを使ってタスクを実行します。 - -#### spawn で非同期タスク実行 - -時間のかかるタスク（Web検索、API呼び出し）には `spawn` ツールを使って**サブエージェント**を作成します： - -```markdown -# 定期タスク - -## クイックタスク（直接応答） -- 現在時刻を報告 - -## 長時間タスク（spawn で非同期） -- AIニュースを検索して要約 -- メールをチェックして重要なメッセージを報告 -``` - -**主な特徴:** - -| 機能 | 説明 | -|------|------| -| **spawn** | 非同期サブエージェントを作成、ハートビートをブロックしない | -| **独立コンテキスト** | サブエージェントは独自のコンテキストを持ち、セッション履歴なし | -| **message ツール** | サブエージェントは message ツールで直接ユーザーと通信 | -| **非ブロッキング** | spawn 後、ハートビートは次のタスクへ継続 | - -#### サブエージェントの通信方法 - -``` -ハートビート発動 - ↓ -エージェントが HEARTBEAT.md を読む - ↓ -長いタスク: spawn サブエージェント - ↓ ↓ -次のタスクへ継続 サブエージェントが独立して動作 - ↓ ↓ -全タスク完了 message ツールを使用 - ↓ ↓ -HEARTBEAT_OK 応答 ユーザーが直接結果を受け取る -``` - -サブエージェントはツール（message、web_search など）にアクセスでき、メインエージェントを経由せずにユーザーと通信できます。 - -**設定:** - -```json -{ - "heartbeat": { - "enabled": true, - "interval": 30 - } -} -``` - -| オプション | デフォルト | 説明 | -|-----------|-----------|------| -| `enabled` | `true` | ハートビートの有効/無効 | -| `interval` | `30` | チェック間隔（分）、最小5分 | - -**環境変数:** -- `PICOCLAW_HEARTBEAT_ENABLED=false` で無効化 -- `PICOCLAW_HEARTBEAT_INTERVAL=60` で間隔変更 - -### プロバイダー - -> [!NOTE] -> Groq は Whisper による無料の音声文字起こしを提供しています。設定すると、あらゆるチャンネルからの音声メッセージがエージェントレベルで自動的に文字起こしされます。 -

- -### モデル設定 (model_list) - -> **新機能！** PicoClaw は現在 **モデル中心** の設定アプローチを採用しています。`ベンダー/モデル` 形式（例: `zhipu/glm-4.7`）を指定するだけで、新しいプロバイダーを追加できます—**コードの変更は一切不要！** - -この設計は、柔軟なプロバイダー選択による **マルチエージェントサポート** も可能にします： - -- **異なるエージェント、異なるプロバイダー** : 各エージェントは独自の LLM プロバイダーを使用可能 -- **フォールバックモデル** : 耐障性のため、プライマリモデルとフォールバックモデルを設定可能 -- **ロードバランシング** : 複数のエンドポイントにリクエストを分散 -- **集中設定管理** : すべてのプロバイダーを一箇所で管理 - -#### 📋 サポートされているすべてのベンダー -

- -### Configuração de Modelo (model_list) - -> **Novidade!** PicoClaw agora usa uma abordagem de configuração **centrada no modelo**. Basta especificar o formato `fornecedor/modelo` (ex: `zhipu/glm-4.7`) para adicionar novos provedores—**nenhuma alteração de código necessária!** - -Este design também possibilita o **suporte multi-agent** com seleção flexível de provedores: - -- **Diferentes agentes, diferentes provedores** : Cada agente pode usar seu próprio provedor LLM -- **Modelos de fallback** : Configure modelos primários e de reserva para resiliência -- **Balanceamento de carga** : Distribua solicitações entre múltiplos endpoints -- **Configuração centralizada** : Gerencie todos os provedores em um só lugar -
