From 0c26fb0d1e6cff0e159d1a5ae23c703545ff7f86 Mon Sep 17 00:00:00 2001 From: Leoyzen Date: Tue, 7 Jul 2026 21:33:14 +0800 Subject: [PATCH 01/49] =?UTF-8?q?spec:=20unify-hook-system=20=E2=80=94=20T?= =?UTF-8?q?urn.execute()=20hook=20firing=20for=20all=20agent=20types?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit OpenSpec change proposing unified hook architecture that fires all 4 hook types (pre_turn, post_turn, pre_tool_use, post_tool_use) in Turn.execute() via HookAwareTurn mixin, replacing fragmented firing in _run_stream_once() and RunHandle.start(). Key decisions: - D1: ALL hooks fire in Turn.execute() (convergence point for standalone + SessionPool) - D2: ACP tool hooks advisory (ToolCallStart/Complete), permission hooks blocking - D3: Keep Hook types, retire AgentHooks.as_capability() adapter - D4: HookAwareTurn mixin handles ALL 4 hook types - D5: Rename pre_run/post_run → pre_turn/post_turn (deprecated aliases, remove v0.5.0) - D6: Three-tier test strategy (core/smoke/integration) - D7: Dead code cleanup (stripping hack, delegate methods, broken tests) Known gap: ACP standalone mode uses inline _stream_events() that bypasses ACPTurn.execute() — hooks retained in _run_stream_once() until ACPAgentAPI adapter is built (future work, tasks.md section 11). Implements #124 (sub-issue of #123 audit).

Hooks are collected in `AgentHooks` which dispatches them in parallel with deny>ask>allow priority combination. + +**Current state has three critical gaps:** + +1. **SessionPool path missing run hooks**: `pre_run`/`post_run` fire in `BaseAgent._run_stream_once()` (standalone mode only).

The subprocess emits `session/update` events (ToolCallStart/Progress/Complete) that agentpool can observe, but cannot intercept before execution. The only blocking point is `session/request_permission`. + +3. **Test coverage is fundamentally broken**: The existing test suite only tests `AgentHooks._run_hooks()` dispatch logic in isolation and standalone-mode hook firing. No integration test verifies hook firing through the SessionPool execution path. No smoke test checks hook coverage for ACP agents. The `NativeAgentHookManager.as_capability()` method strips all pydantic-ai hook entries to prevent double-firing (making `Hooks` capability a no-op), and no test catches this.

In multi-turn `RunHandle.start()` loops, `pre_turn` should fire before each turn's prompt and `post_turn` after each turn's response. This change renames `pre_run`/`post_run` → `pre_turn`/`post_turn` to reflect the correct per-turn semantic. + +**Existing infrastructure:** +- `Turn` ABC at `orchestrator/turn.py:19` — both `NativeTurn` and `ACPTurn` inherit from it +- `ACPTurn.execute()` event streaming at `turn.py:152` — processes ACP events +- `NativeAgentHookManager` (661 LOC) already bridges to pydantic-ai via `_ToolInterceptCapability` (an `AbstractCapability` subclass) +- `NativeAgentHookManager.as_capability()` (lines 483-486 of `hook_manager.py`) calls `AgentHooks.as_capability()` then strips `_registry` entries to prevent double-firing, making the `Hooks` capability a no-op.

Moving to `Turn.execute()` means hooks fire regardless of which path initiated the run. + +**Per-turn semantics**: `pre_turn` fires before the LLM call / ACP prompt in each turn. `post_turn` fires after the response completes in each turn. In a multi-turn run (steer/followup), each turn triggers its own `pre_turn`/`post_turn` pair. + +**Hooks access**: `Turn` implementations access hooks via `self._hooks` property (provided by `HookAwareTurn`). For native agents, hooks come from `BaseAgent.hooks` (line 264). For ACP agents, `ACPAgent` already accepts `hooks` param (line 159) and passes it to `ACPTurn`. + +**Standalone mode (native agents)**: No special handling needed — `run_stream()` Path B calls `_stream_events()` which creates `NativeTurn` and calls `turn.execute()` (verified at `native_agent/agent.py:1154-1163`). Hooks fire via `HookAwareTurn`. + +**Standalone mode (ACP agents) — known gap**: `ACPAgent._stream_events()` (`acp_agent.py:412-511`) is an inline implementation that does **NOT** use `ACPTurn.execute()`. This means ACP standalone mode will not fire hooks via `HookAwareTurn`. Additionally, `ACPAgent.create_turn()` (`acp_agent.py:648-652`) has a TODO noting that `ACPAgentAPI` does not fully implement `ACPClientProtocol` (missing `stream_events()` and `get_messages()`), so `ACPTurn.execute()` may fail at runtime in SessionPool mode until an adapter is built. + +**Mitigation**: During Phase 1-3, `_run_stream_once()` hook firing is kept for ACP standalone (guarded by `hooks_fired` to prevent double-firing with the old path). Phase 3 only removes `_run_stream_once()` firing for **native** agents (where `NativeTurn.execute()` is confirmed working). ACP `_run_stream_once()` firing is retained until the ACP standalone path is refactored. + +**Future work** (out of scope for this change): +- Refactor `ACPAgent._stream_events()` to delegate to `ACPTurn.execute()`, making it the true convergence point for ACP standalone +- Build the `ACPAgentAPI` adapter implementing `ACPClientProtocol` fully (`stream_events()`, `get_messages()`) +- Once ACP standalone routes through `ACPTurn.execute()`, remove `_run_stream_once()` firing for ACP agents +- Tracked as a follow-up issue, not blocked by this change + +**Alternatives considered**: +- Fire `pre_turn`/`post_turn` in `RunHandle.start()` — rejected because (a) `RunHandle.start()` manages the turn loop, not individual turns; (b) per-turn hooks would need to be inside the loop anyway, duplicating logic; (c) `RunHandle.start()` is not called in standalone Path B +- Fire in `BaseAgent.run()` — rejected because `BaseAgent.run()` doesn't cover all SessionPool execution paths (RunHandle.start() is the actual convergence point for server-driven runs, and RunHandle calls turn.execute() not BaseAgent.run()) +- Keep in `_run_stream_once()` and also add to RunHandle — rejected because it causes double-firing and requires stripping hacks (the current problem) +- Route standalone through `create_run_stream()` → `RunHandle.start()` — considered as future cleanup but too large for Phase 1 +- Refactor `ACPAgent._stream_events()` to use `ACPTurn.execute()` — future work, requires `ACPAgentAPI` adapter implementing full `ACPClientProtocol` + +### D2: ACP tool hooks are advisory, permission hooks are blocking + +**Decision**: ACP `pre_tool_use` hooks fire on `ToolCallStart` event (advisory only — cannot block). ACP `post_tool_use` hooks fire on `ToolCallComplete` (can modify output by replacing the event before yielding). Blocking pre-tool interception uses `session/request_permission`. + +**Permission hook priority**: In `ACPClientHandler.request_permission()` (line 208, `client_handler.py`), hooks SHALL fire **before** the `auto_approve` check (line 217). Priority chain: hooks → auto_approve → callback → input_provider. Hooks represent explicit security policy that should override convenience settings. + +**ACP output modification**: In `ACPTurn.execute()` (line 152, `turn.py`), events from `acp_to_native_event(update)` are intercepted before yielding. If `post_tool_use` hooks return `modified_output`, the `ToolCallCompleteEvent`'s output field is replaced before the event is yielded to the consumer. This modifies the event stream, not the subprocess's internal state. + +**Rationale**: ACP tool execution is a black box. By the time `ToolCallStart` is emitted, the subprocess has already started executing the tool. The only pre-execution interception point is `request_permission`, which the ACP agent emits before running certain tools. + +**Alternatives considered**: +- No ACP tool hooks — rejected because users need observability even if they can't block +- Block via `request_permission` only — rejected because not all tools trigger permission requests +- Proxy architecture (intercept JSON-RPC frames) — future work in `acp-proxy-chain-refactor`, which adds `HookProxy` for wire-level blocking. This change provides process-level advisory hooks as a baseline. + +### D3: Keep Hook types, retire AgentHooks.as_capability() adapter + +**Decision**: Keep `Hook`/`CallableHook`/`CommandHook`/`PromptHook` types and `AgentHooks._run_hooks()` parallel dispatch. Remove `AgentHooks.as_capability()` bridge methods. All 4 hook types fire from `Turn.execute()` (via `HookAwareTurn`) — run hooks AND tool hooks. + +**Rationale**: The Hook types provide value pydantic-ai lacks: subprocess hooks (`CommandHook`), LLM-evaluated hooks (`PromptHook`), regex input matching, and parallel deny>ask>allow priority combination. The `as_capability()` adapter is a transitional bridge that creates the double-firing problem. + +**Tool hooks for native agents**: `_ToolInterceptCapability` remains as the native-only tool hook implementation (it IS a pydantic-ai `AbstractCapability`). But `pre_turn`/`post_turn` firing moves from `_run_stream_once()` / `BaseAgent` to `NativeTurn.execute()` via `HookAwareTurn`. + +**Alternatives considered**: +- Port everything to pydantic-ai capabilities — rejected because `CommandHook`/`PromptHook` have no pydantic-ai equivalents, and parallel deny>ask>allow combination doesn't exist in pydantic-ai (sequential dispatch only) +- Keep `as_capability()` — rejected because it requires stripping hooks to prevent double-firing, which is fragile and confusing + +### D4: HookAwareTurn mixin handles ALL 4 hook types + +**Decision**: Create `HookAwareTurn` mixin in `orchestrator/turn.py` (alongside existing `Turn` ABC at line 19) that handles ALL 4 hook types: +- `fire_pre_turn_hooks(prompt, **extra) -> HookResult | None` — called before LLM/ACP prompt +- `fire_post_turn_hooks(result, **extra) -> HookResult | None` — called after response +- `fire_pre_tool_hooks(tool_name, tool_input, **extra) -> HookResult | None` — called before tool execution +- `fire_post_tool_hooks(tool_name, tool_output, **extra) -> HookResult | None` — called after tool execution + +Both `NativeTurn` and `ACPTurn` inherit from `HookAwareTurn`. `NativeTurn` delegates tool hooks to `_ToolInterceptCapability` (which already handles them via pydantic-ai capability). `ACPTurn` implements tool hooks directly (advisory on ToolCallStart, modifying on ToolCallComplete). + +**Rationale**: `Turn.execute()` is the single convergence point. Having all 4 hook types in one mixin ensures: +1. Consistent firing across agent types +2. No hooks lost when switching execution modes +3. Future agent types inherit all 4 hooks by inheriting `HookAwareTurn` +4. Per-turn semantics are correct (pre_turn/post_turn fire per turn, not per run-loop) + +**Alternatives considered**: +- Put helpers in base `Turn` class — rejected because not all Turn types need hooks (e.g., mock test turns) +- Separate mixins for run hooks vs tool hooks — rejected because it fragments the hook lifecycle and makes inheritance complex +- Standalone utility functions — rejected because they need access to `self._hooks` and `self._session_id` + +### D5: Rename pre_run/post_run → pre_turn/post_turn + +**Decision**: Rename `pre_run`/`post_run` to `pre_turn`/`post_turn` throughout the codebase: hook event names, `AgentHooks` method names (`run_pre_run_hooks` → `run_pre_turn_hooks`), config fields, `HookInput.event` values, docs. Old names kept as deprecated aliases during transition (emit `DeprecationWarning`), removed in v0.5.0. + +**Rationale**: The names `pre_run`/`post_run` were correct when "run" = "one agent execution" = one prompt → one response. With multi-turn `RunHandle.start()` loops, "run" now means the entire run loop. The correct semantic is per-turn: each turn's prompt triggers `pre_turn`, each turn's response triggers `post_turn`.

A smoke test that simply asserts "pre_turn hook was called once" would have caught the current breakage. These tests are cheap, fast, and specifically designed to catch "hooks silently stopped firing" regressions. + +3. **Integration (end-to-end behavioral)**: Verify that hook **results** actually take effect — deny blocks execution, modified_output replaces output, additional_context is injected, CommandHook subprocess receives correct JSON, PromptHook LLM evaluation returns correct decision. + +**Rationale**: The current breakage (hooks not firing in SessionPool) was never caught because tests only covered dispatch logic in isolation. A smoke test asserting "hook was called when running through SessionPool" would have immediately caught it. The three-tier approach ensures both presence (smoke) and correctness (integration) of hook behavior. + +**Test matrix**: + +| Test Level | What It Catches | Agent Types | Execution Modes | +|---|---|---|---| +| Core | Dispatch logic, result combination, input construction | Mock agents | N/A (unit) | +| Smoke | Hooks fire at all (presence check) | Native + ACP | Standalone + SessionPool | +| Integration | Hook results take effect (deny blocks, output modified) | Native + ACP | Standalone + SessionPool | + +**Smoke test hook coverage matrix** (the "never again" tests): + +| Hook Event | Native Standalone | Native SessionPool | ACP Standalone | ACP SessionPool | +|---|---|---|---|---| +| pre_turn | smoke | smoke | smoke | smoke | +| post_turn | smoke | smoke | smoke | smoke | +| pre_tool_use | smoke | smoke | smoke (advisory) | smoke (advisory) | +| post_tool_use | smoke | smoke | smoke | smoke | + +Each cell is a single test that asserts the hook callback was invoked. If any cell fails, CI blocks the merge. + +### D7: Dead code and broken test cleanup + +**Decision**: Identify and remove code that is dead, broken, or testing broken behavior. + +**Categories of dead/broken code to remove:** +1. `NativeAgentHookManager.as_capability()` stripping hack (lines 483-486 of `hook_manager.py` — sets `_registry` entries to empty lists) — dead because it makes Hooks a no-op. Note: `AgentHooks.as_capability()` itself does NOT strip; the stripping is in `NativeAgentHookManager.as_capability()`. +2. `NativeAgentHookManager` delegate methods (`run_pre_run_hooks`, `run_post_run_hooks`, `run_pre_tool_hooks`, `run_post_tool_hooks`) — dead after Turn takes over firing +3. `BaseAgent._run_stream_once()` pre_run/post_run hook firing blocks — dead after Turn takes over firing +4. Tests that assert hooks DON'T fire in SessionPool mode (testing broken behavior as correct) +5. Tests that mock around the broken path instead of testing real firing +6. Tests that validate the stripping hack behavior + +**Rationale**: Dead code confuses readers and broken tests give false confidence. Removing them as part of this change ensures the codebase reflects the new unified architecture. + +## Risks / Trade-offs + +**[Double-firing during migration]** → Guard with `run_ctx.hooks_fired: set[str]` field on `AgentRunContext` (line 76, `agents/context.py`). During transition, if a hook point was already fired in the new path (Turn), skip it in the old path (`_run_stream_once()`). Remove the guard when old path is removed. + +**[ACP advisory hooks confuse users]** → Document prominently that ACP `pre_tool_use` is advisory. Log a warning when a deny result is returned but cannot be enforced. + +**[Breaking change in v0.5.0]** → `AgentHooks.as_capability()` removal AND `pre_run`/`post_run` name removal are breaking. Provide deprecation warnings before removal. Document migration path. + +**[NativeAgentHookManager slimming may break subclassers]** → Check for subclasses before removing methods. If any exist, provide delegation shims with deprecation warnings. + +**[Test cleanup removes coverage]** → Only remove tests that validate broken behavior. Replace with new smoke/integration tests that validate correct behavior. Net test coverage should increase, not decrease. + +**[HookProxy interaction with acp-proxy-chain-refactor]** → When `HookProxy` is active in the ACP proxy chain, it handles hooks at the wire level (blocking). `HookAwareTurn` on `ACPTurn` SHALL disable itself via the `hooks_fired` guard when `HookProxy` is active.

New scenario in acp-server spec. 3. HookAwareTurn context access: Use class variable annotations (_run_ctx: AgentRunContext | None = None) instead of properties. Properties prevent subclass __init__ from setting via simple assignment. Mock turns inherit None default (guard skipped). 4. hooks_fired breaks multi-turn: Clear hooks_fired at start of each turn (RunHandle.start() loop for Path A, _run_stream_once() for Path B). Also fix guard direction: in Path B, old path fires FIRST and adds to hooks_fired; Turn.execute() checks and skips. The original design had the direction backwards.

The `_stream_events()` bypass is deleted. + +**Rationale**: The dual-path divergence (Path A: TurnRunner→create_turn→execute vs Path B: run_stream→_stream_events) is the root cause of ACPTurn being dead code. By making ACPTurn functional via `ACPClientAdapter`, both paths converge. This also means `TurnRunner` works with ACP agents (previously broken). + +**Alternative considered**: Keep dual paths, just fix ACPTurn for the TurnRunner path. Rejected — maintaining two execution paths for the same agent type is a maintenance burden and was the original cause of the divergence. + +### D3: ACPClientAdapter Design + +**Decision**: `ACPClientAdapter` wraps `ACPAgentAPI` to implement `ACPClientProtocol`. It: +- `prompt()`: Launches `api.prompt()` as a background task (fire-and-forget), returns immediately +- `stream_events()`: Returns an `asyncio.Queue` that `client_handler.session_update()` pushes to directly (no polling) +- `get_messages()`: Calls `api.get_messages()` after prompt completes + +**Rationale**: This is the ~50-line adapter that was identified as missing. The key insight is that `ACPAgentAPI.prompt()` is blocking (returns `PromptResponse` after all notifications), but `ACPClientProtocol.prompt()` should be non-blocking (returns immediately, notifications arrive via `stream_events()`). The adapter bridges this by making `prompt()` fire-and-forget and routing notifications to an async queue. + +**Alternative considered**: Make `ACPAgentAPI` natively async with streaming. Rejected — would require deep changes to the ACP client library; the adapter is a localized bridge. + +### D4: HookProxy Adapter Pattern + +**Decision**: `HookProxy` implements the `Proxy` protocol and wraps existing `Hook` instances. It handles **all 4 hook types** by mapping ACP wire messages to `HookInput` events: + +- `session/prompt` → `HookInput(event="pre_turn")` — hook can inject context (`additional_context`), deny (block prompt), or modify prompt before forwarding +- `session/update` with `ToolCallStart` → `HookInput(event="pre_tool_use")` — hook can modify tool input (`modified_input`) or deny (block tool call before it reaches terminal agent) +- `session/update` with `ToolCallComplete` → `HookInput(event="post_tool_use")` — hook can replace tool output (`modified_output`) +- `session/update` with `AgentMessageChunk` (final) → `HookInput(event="post_turn")` — hook can modify agent response (`modified_output`) + +`HookResult.decision=="deny"` → proxy stops forwarding (blocking, not advisory). `HookResult.additional_context` → prepended to prompt. `HookResult.modified_input` → replaces tool input. `HookResult.modified_output` → replaces output. + +**Hook semantics are per-turn, not per-run-loop**: The `pre_turn`/`post_turn` names (renamed from `pre_run`/`post_run` by `unify-hook-system`) reflect the correct per-turn semantic. In a multi-turn `RunHandle` (with steer/followup), these fire for **each turn**, not just the first and last. HookProxy naturally implements this because `session/prompt` and `session/update` flow through the proxy chain on every turn. + +**Rationale**: The RFD says proxies subsume hooks. But rewriting all hook implementations would waste existing, tested code. The adapter pattern preserves the hook system while elevating it to wire-protocol level. Same hook can be used for both native agents (via `HookAwareTurn` in-process) and ACP agents (via `HookProxy` at wire level). HookProxy is strictly superior to in-process hooks for ACP agents because it intercepts messages **before** they reach the terminal agent subprocess — enabling true blocking, not just advisory warnings. + +**Alternative considered**: Replace hooks entirely with proxy implementations. Rejected — existing hooks (`CallableHook`, `CommandHook`, `PromptHook`) are tested and in use. Rewriting them as proxies would be a larger scope change with no benefit. + +### D5: Passthrough Optimization + +**Decision**: When a proxy has no interception logic for a given message type, it forwards the message without deserializing/reserializing. The Conductor tracks which proxies are "transparent" for which message types and short-circuits the chain. + +**Rationale**: This solves the double conversion problem. In the current architecture, nesting ACP server + client causes ~1600 lines of ACP→native→ACP conversion. With proxy chains, a passthrough proxy forwards the raw JSON-RPC message without parsing. Only proxies that explicitly register interest in a message type pay the deserialization cost. + +**Alternative considered**: Always deserialize and re-serialize. Rejected — defeats the purpose of proxy chains for passthrough scenarios. + +### D6: Terminal Agent Interface + +**Decision**: Terminal agents implement the existing `acp.Agent` protocol (no changes). The Conductor detects terminal agents by checking `proxy_initialized` capability during `initialize()` — if the agent responds to `initialize` (not `proxy/initialize`), it's a terminal agent. + +**Rationale**: This follows the RFD exactly. Terminal agents don't know about proxy chains — they just handle `session/prompt` and emit `session/update`. The Conductor manages the chain and forwards unwrapped messages to the terminal agent. + +**Alternative considered**: Create a `TerminalAgent` protocol. Rejected — the existing `Agent` protocol already defines the terminal agent interface. Adding a new protocol would be redundant. + +### D7: YAML Configuration + +**Decision**: New `proxy_chain:` section in agent config: + +```yaml +agents: + my_agent: + type: acp + command: goose + args: [acp] + proxy_chain: + - type: context_injection + agents_md: true + skills: [code-review, debugging] + - type: tool_provider + mcp_servers: [filesystem, git] + - type: hook + event: pre_tool_use + command: ./security-check.sh +``` + +When `proxy_chain` is omitted, the Conductor runs with zero proxies (direct conductor→agent). + +**Rationale**: Declarative configuration matches agentpool's YAML-first philosophy. Each proxy entry maps to a registered proxy implementation. The `type` field discriminates which proxy class to instantiate. + +**Alternative considered**: Programmatic configuration only. Rejected — agentpool is YAML-first; programmatic API can be added later if needed. + +### D8: EventBus and Conductor Coexistence + +**Decision**: EventBus handles framework-level events (`RichAgentStreamEvent`), Conductor handles ACP wire-level messages (JSON-RPC). ACPTurn is the bridge — it receives ACP messages from the Conductor and converts them to `RichAgentStreamEvent` for the EventBus. + +**Rationale**: EventBus is the existing event distribution system for protocol servers. Conductor operates at a different abstraction layer (wire protocol). Mixing them would conflate concerns. ACPTurn already does this conversion — it just needs to be functional (which D3 solves). + +### D9: HookProxy and HookAwareTurn Coexistence + +**Decision**: Two hook firing mechanisms coexist for ACP agents. The Conductor controls which mechanism is active by controlling whether hooks are passed to `ACPTurn`: + +| Mechanism | Scope | Firing Location | Capability | When Active | +|---|---|---|---|---| +| `HookAwareTurn` (v1) | All 4 hook types | `ACPTurn.execute()` (in-process) | Advisory (can't block subprocess) | No HookProxy in chain | +| `HookProxy` (v2) | All 4 hook types | Proxy chain (wire-level) | Blocking (intercepts before terminal agent) | HookProxy in chain | + +**Activation rules**: +- When Conductor has a `HookProxy` in the chain: Conductor passes `_hooks=None` to `ACPTurn`. `HookAwareTurn`'s guard (`if self._hooks is None: return None`) skips all hook firing. Hooks fire at wire-level via `HookProxy`. +- When no `HookProxy` in chain: Conductor passes the agent's `AgentHooks` to `ACPTurn`. `HookAwareTurn` fires all 4 hook types in-process (advisory for tool hooks). +- Conductor **auto-inserts** `HookProxy` at chain position 0 when agent has hooks configured and no explicit `HookProxy` in `proxy_chain`. + +**Why not use `hooks_fired` guard**: The `unify-hook-system` spec clears `hooks_fired` per-turn (to support multi-turn runs). If HookProxy set keys at chain init, they'd be cleared in turn 2+. Passing `_hooks=None` is simpler and doesn't interact with the per-turn clearing logic. The `hooks_fired` guard remains solely for the `_run_stream_once()` → `Turn.execute()` migration in `unify-hook-system`. + +**Migration path**: `unify-hook-system` implements `HookAwareTurn` (v1) first, including Section 11 "Future Work" which describes building the `ACPClientAPI` adapter. `acp-proxy-chain-refactor` Phase 1 implements that adapter (`ACPClientAdapter`), making `ACPTurn.execute()` the single ACP execution path. Phase 4 adds `HookProxy` (v2). Eventually, when all ACP agents use Conductor, `HookAwareTurn` on `ACPTurn` can be removed (kept only for native `NativeTurn`). + +**Rationale**: Both mechanisms serve the same hooks (`CallableHook`, `CommandHook`, `PromptHook`) — they differ only in WHERE interception happens (in-process vs wire). The `_hooks=None` approach is cleaner than `hooks_fired` because it doesn't require coordination with the per-turn clearing logic. + +**Alternative considered**: Use `hooks_fired` guard as originally proposed. Rejected — per-turn clearing in `unify-hook-system` would require HookProxy to re-set keys every turn, creating unnecessary coupling. Passing `_hooks=None` is a single assignment at Conductor construction time. + +## Risks / Trade-offs + +**[RFD not ratified]** → We implement against the current draft. If `proxy/initialize` or `proxy/successor` method names change, only the wire method names need updating — the Conductor's internal architecture is stable. Mitigation: isolate wire method names in a single constants module. + +**[No Python reference implementation]** → The RFD has a working Rust impl (`sacp-conductor`, `sacp-proxy`) but no Python reference. We're the first Python implementation. Mitigation: follow the RFD spec closely, use the Rust impl as reference for edge cases. + +**[Large refactoring scope]** → ~2-3 weeks of work across 6 phases. Mitigation: phased delivery — Phase 1 (ACPTurn fix) is independently shippable and immediately useful. Each subsequent phase builds on the previous without breaking. + +**[Backward compatibility]** → `ACPAgent._stream_events()` signature changes. `create_turn()` behavior changes (previously crashed, now works). Mitigation: these are internal methods. The public `run()`/`run_stream()` API remains stable. Users who depended on `_stream_events()` behavior are depending on a workaround. + +**[HookProxy message mapping complexity]** → Mapping ACP wire messages to hook lifecycle events requires understanding both systems. Mitigation: comprehensive tests for each message type → hook event mapping. The mapping is finite (4 hook events × ~6 ACP message types). + +**[Conductor subprocess management]** → Conductor now manages subprocess lifecycle instead of ACPAgent. If the Conductor crashes, subprocesses may orphan. Mitigation: Conductor uses task groups (anyio) for structured concurrency; subprocess cleanup runs in finally block. + +## Migration Plan + +1. **Phase 1** (shippable independently): Fix ACPTurn via ACPClientAdapter. Replace polling with async push. This alone fixes 2 of 3 critical issues. +2. **Phase 2-3**: Implement Conductor + Proxy protocol. Rewrite ACPAgent to use Conductor. Old ACPAgent code remains until new path is verified. +3. **Phase 4**: Add built-in proxy implementations (HookProxy, ContextInjectionProxy, ToolProviderProxy). +4. **Phase 5**: Refactor server-side `AgentPoolACPAgent` as terminal agent. +5. **Phase 6**: Delete dead code, legacy paths, migrate ToolManagerBridge → ResourceProvider. + +**Rollback**: Phases 1-3 can be feature-flagged via `use_conductor: true` in agent config. If issues arise, set `use_conductor: false` to fall back to the old `_stream_events()` path. Flag removed in Phase 6 after confidence is established. + +## Open Questions + +- Should the Conductor support hot-swapping proxies at runtime (add/remove proxy without restarting the chain)? Currently out of scope, but the design should not preclude it. +- How should proxy chains interact with the graph-based team execution? If a team member is an ACP agent with a proxy chain, does the chain execute within the Step's `call()` method?

The key insight is that `ACPAgentAPI.prompt()` is blocking (returns `PromptResponse` after all notifications), but `ACPClientProtocol.prompt()` should be non-blocking (returns immediately, notifications arrive via `stream_events()`). The adapter bridges this by making `prompt()` fire-and-forget and routing notifications to an async queue. +**Rationale**: The original `ACPClientProtocol` required `prompt()` to return `PromptResponse` and `stream_events()` to take a `response` parameter. This assumes synchronous completion — `prompt()` blocks until all notifications arrive, then `stream_events(response)` iterates them. But `ACPAgentAPI.prompt()` is blocking and the adapter needs to invert this: return immediately from `prompt()`, stream events as they arrive, then expose `stop_reason` after completion. + +The protocol change is internal to this change's scope — `ACPClientProtocol` is only implemented by `ACPClientAdapter` and consumed by `ACPTurn`.

- Returns: - A CommandContext configured with the agent context, output capture, and command store. - """ - from agentpool.agents.context import AgentContext - - assert state.command_store is not None, "Command store must be initialized" - - agent_ctx = AgentContext(node=state.agent, data=None) - return CommandContext( - output=_CommandOutputCapture(), - data=agent_ctx, - command_store=state.command_store, - ) -``` - -### Requirements Met - -| Requirement | Status | -|-------------|--------| -| Function signature correct | ✅ def _create_command_context(state: ServerState) -> CommandContext | -| Creates CommandContext | ✅ Returns slashed.CommandContext instance | -| Uses agent from state | ✅ Via state.agent.get_context() wrapped in AgentContext | -| Handles output capture | ✅ Uses _CommandOutputCapture helper class | -| Used by Task 3 | ✅ Called in _execute_slashed_command() at line 129 | -| Working directory resolution | ✅ Available via state.working_dir | - -### Verification Results - -- **Syntax check**: PASSED -- **Ruff lint**: No new errors (only pre-existing F811) -- **Type safety**: CommandContext properly typed - -### Helper Class - -```python -class _CommandOutputCapture: - """Output writer that captures command output to a string buffer.""" - - def __init__(self) -> None: - self._buffer: list[str] = [] - - def print(self, message: str) -> None: - """Write a message to the buffer.""" - self._buffer.append(message) - - def __str__(self) -> str: - """Get the captured output as a single string.""" - return "\n".join(self._buffer) -``` - -### Integration Pattern - -```python -# In _execute_slashed_command: -cmd_ctx = _create_command_context(state) -await command.execute(cmd_ctx, args, {}) -``` -

-### Implementation Pattern -For background task management (run_in_background), we use a hybrid approach: -1. Create `self._background_run_ctx = AgentRunContext()` when starting background task -2. Use local variable `run_ctx = self._background_run_ctx` in inner function with assertion -3. Check `run_ctx.cancelled` in the loop condition and exception handlers -4. Update `stop()` to set `self._background_run_ctx.cancelled = True` -5. Update `is_cancelled()` to check both `self._cancelled` and `self._background_run_ctx.cancelled` - -This ensures background tasks have isolated cancellation state while maintaining backward compatibility. - ---- - -## Task 2.3: Update NativeAgent for Context Compatibility - COMPLETED - -### Changes Made - -#### 1. Fixed `_event_queue` usage in `_process_node_stream` (line 766) -- Changed from `self._event_queue` to `run_ctx.event_queue` -- Ensures each concurrent call uses its own isolated event queue - -#### 2. Fixed `_event_queue` usage in `_stream_events` (lines 846-848) -- Changed from `self._event_queue` to `run_ctx.event_queue` -- Part of the merge_queue_into_iterator call in the agent iteration task - -#### 3. Fixed `_current_stream_task` usage in `_interrupt` (line 967) -- Changed from `self._current_stream_task` to `run_ctx.current_task` -- The method now properly uses the task from the provided run context - -#### 4. Added missing `_injection_manager` initialization in BaseAgent (line 234) -- Added `self._injection_manager = PromptInjectionManager()` to BaseAgent.__init__ -- This was causing AttributeError when creating NativeAgent instances - -### Test Results - -- `test_native_agent_concurrent`: PASSED ✓ -- `test_concurrent_calls_complete`: PASSED ✓ -- `test_concurrent_cancellation_isolation`: PASSED ✓ -- All native_agent tests: PASSED ✓ (16 passed, 1 failed - unrelated test design issue) - -### Key Implementation Notes - -1.

-### Concrete Deliverables - -1. **Exception Hierarchy** (`src/agentpool/skills/exceptions.py`) - - `SkillError` base class - - `SkillNotFoundError` with available skills list - - `ReferenceNotFoundError` for reference files - - `SecurityError` for path traversal attempts - - `ProviderError` for provider operation failures - -2. **URI Resolver** (`src/agentpool/skills/uri_resolver.py`) - - `ResolvedSkillURI` dataclass for parsing skill:// URIs - - `SkillURIResolver` class for resolving URIs to skill content - - Provider priority handling for skill name collisions - - Full URI validation (RFC 3986 compliant) - -3. **LocalResourceProvider** (`src/agentpool/resource_providers/local.py`) - - Implements ResourceProvider interface for filesystem skills - - Uses SkillsRegistry for skill discovery - - Supports `references/` subdirectory access - - LRU caching with TTL for skill listings - - Path traversal protection with `Path.relative_to()` - -4. **Extended MCPResourceProvider** (`src/agentpool/resource_providers/mcp_provider.py`) - - `get_skills()` returning prompt-based + resource-based skills - - `_get_prompt_skills()` for MCP prompt mapping - - `_get_resource_skills()` for FastMCP Skills Provider protocol - - `get_references()` and `read_reference()` for skill resources - - `_on_skills_changed()` callback for change notifications - -5. **AggregatingResourceProvider Extension** (`src/agentpool/resource_providers/aggregating.py`) - - `get_skills()` override to aggregate from all child providers - - Proper change signal propagation - -6. **Updated load_skill Tool** (`src/agentpool_toolsets/builtin/skills.py`) - - Support for skill:// URI format - - Bare skill name resolution with provider priority - - Reference content loading - - Argument substitution ($1, $2, $@) - -7. **AgentPool Integration** (`src/agentpool/delegation/pool.py`) - - `skill_resolver` property with SkillURIResolver - - `skill_provider` property with AggregatingResourceProvider - - `_setup_skills_provider()` for initialization - - SkillsManager extension with ResourceProvider - -8. **Comprehensive Tests** - - Unit tests for each component - - Integration tests for full workflow - - Mock MCP server tests for skill discovery - - Edge case tests (encoding, traversal, empty paths) - -### Definition of Done - -- [ ] All 7 exception classes implemented and tested -- [ ] URI resolver handles all URI formats from RFC specification -- [ ] LocalResourceProvider passes security audit (path traversal protection) -- [ ] MCPResourceProvider discovers both prompt-based and resource-based skills -- [ ] AggregatingResourceProvider aggregates skills from all providers -- [ ] load_skill tool supports both old (name) and new (URI) formats -- [ ] All tests pass with >80% coverage -- [ ] No breaking changes to existing skill functionality -

-**Research Findings**: -- Zed’s subagent UI depends on `_meta.subagent_session_info` and `_meta.tool_name` on `ToolCallStart`/`ToolCallProgress`. -- The repo already has child-session primitives in core session management. -- Phase 0 must prove whether unknown-session `session/update` is viable through the existing ACP transport. -- Metis flagged a few implementation risks: destructuring needs widening, `subagent_tools.py` has a child-session-id / double-emit issue, and Phase 2 needs a fallback if direct child routing fails. - -### Metis Review -**Identified Gaps** (addressed): -- Child-session identifiers are currently not captured in the relevant event match arms. -- `subagent_tools.py` needs a regression fix for duplicate `SpawnSessionStart` emission. -- Phase 2 must clarify runtime ACP session handling vs persisted core session handling. -- The plan needs an explicit fallback if Phase 0 says direct child routing is impossible. -

-### Must Have -- Zed mode must be explicitly opt-in (`display_mode=zed`). -- Legacy/inline/tool_box behavior must remain unchanged. -- `_meta.tool_name` and `_meta.subagent_session_info` must be present only where RFC allows. - -### Must NOT Have (Guardrails) -- No ACP schema changes. -- No automatic client detection. -- No Zed Parallel Agents / Proxy Chains work. -- No deeper subagent nesting support beyond the RFC scope. -- No accidental `_meta.subagent_session_info` leakage into non-Zed subagent tool calls. - ---- - -## Verification Strategy (MANDATORY) - -> **ZERO HUMAN INTERVENTION** - all verification must be agent-executed. - -### Test Decision -- **Infrastructure exists**: YES -- **Automated tests**: YES, tests-after -- **Framework**: pytest -- **If TDD**: not required here; add regression tests alongside each implementation task -

The guard is specific to server-side agent lifecycle, so it belongs in `src/acp/agent/connection.py` near `_agent_handler()` or a small wrapper around request execution. - -3. **Use Starlette + uvicorn only for the new transport path.** - `uvicorn` is already a core dependency and the repo already instantiates `uvicorn.Server` directly in multiple servers. `starlette` should be promoted from optional-only usage to a core dependency if ACP transport is intended as a first-class server feature. - -4. **Treat shutdown bridging as explicit work, not incidental behavior.** - `ACPServer._start_async()` already passes `self._shutdown_event` into `acp.serve()`, but `BaseServer.stop()` cancels the server task without setting that event. The new transport needs an ACP-side shutdown path that closes connections deterministically. - -5. **Update the Toad helper path during the same change.** - `src/agentpool_cli/ui.py` still shells out to `serve-acp --transport websocket --ws-port ...`; leaving that unchanged would preserve an internal caller on the deprecated transport. - -## Files to touch - -### Transport and protocol - -- `src/acp/transports.py` -- `src/acp/__init__.py` -- `src/acp/agent/connection.py` - -### Server integration - -- `src/agentpool_server/acp_server/server.py` -- `src/agentpool_server/base.py` or an ACP-specific override in `server.py` - -### Config and CLI - -- `src/agentpool_config/pool_server.py` -- `src/agentpool_cli/serve_acp.py` -- `src/agentpool_cli/ui.py` - -### Dependency management - -- `pyproject.toml` - -### Tests - -- `tests/acp/test_streamable_http_transport.py` (new) -- `tests/servers/acp_server/test_streamable_http_integration.py` (new) -- `tests/cli/test_serve_acp_streamable_http.py` (new or merged into existing CLI coverage) - -## Implementation phases - -### Phase 0 - settle two code-level decisions before editing broadly - -1. **Initialize guard location** - - Preferred: add per-connection initialized state inside `AgentSideConnection`. - - Reject: modifying generic `Connection` lifecycle in a way that also affects non-server/client paths. - -2. **Shutdown behavior ownership** - - Preferred: make `ACPServer.stop()` set `_shutdown_event` before delegating to base stop behavior, or otherwise ensure the serving coroutine sees the event before cancellation. - - Verify this against current `BaseServer.start_in_background()` / `stop()` semantics before implementation. - -Exit criteria: -- We know exactly where the initialize guard flips from false to true. -- We know exactly which stop path triggers uvicorn shutdown and connection cleanup. - -### Phase 1 - add the new transport type and server runtime - -1. Add `ACPWebSocketTransport` to `src/acp/transports.py` with: - - `host: str = "localhost"` - - `port: int = 8080` - -2. Extend `Transport` to include: - - `ACPWebSocketTransport` - - `Literal["streamable-http"]` - -3. Extend `serve()` normalization so: - - `"stdio"` -> `StdioTransport()` - - `"websocket"` -> legacy `WebSocketTransport()` - - `"streamable-http"` -> `ACPWebSocketTransport()` - -4. Add a new dispatch arm for `ACPWebSocketTransport` calling `_serve_streamable_http(...)`. - -5. Implement `_serve_streamable_http(...)` in `src/acp/transports.py`: - - Build a Starlette app with a WebSocket route at `/acp`. - - Instantiate `uvicorn.Server(uvicorn.Config(...))` directly, matching current repo practice. - - Bridge the passed `shutdown_event` to `server.should_exit = True`. - - Keep a local set of active `AgentSideConnection` objects for final cleanup. - -6. Add Starlette-specific stream adapters: - - `_StarletteWebSocketReadStream` - - `_StarletteWebSocketWriteStream` - Requirements: - - `receive_text()` / `send_text()` based transport - - newline compatibility with the existing JSON-RPC line protocol - - `WebSocketDisconnect` translated to `anyio.EndOfStream` - -7. During handshake, return `Acp-Connection-Id` using `websocket.accept(headers=[...])`. - -Exit criteria: -- The new transport can be selected internally. -- A Starlette-backed server can accept a WebSocket at `/acp` and create an `AgentSideConnection`. - -### Phase 2 - implement lifecycle enforcement and cleanup guarantees - -1. Add per-connection initialized state on the agent side. - -2. Reject any request before `initialize` with JSON-RPC error `-32002`. - - Keep behavior request-scoped. - - Do not add byte-stream interception. - -3. Mark the connection initialized only after a successful `initialize` handling path. - - If initialize fails, keep the connection uninitialized. - -4. Ensure endpoint cleanup is symmetric: - - graceful disconnect - - `WebSocketDisconnect` - - uvicorn shutdown - - task cancellation / abnormal close - -5. Call `AgentSideConnection.close()` exactly once per live connection path. - -Exit criteria: -- Non-initialize requests fail correctly before session bootstrap. -- Disconnect and shutdown paths do not leak live ACP connections. - -### Phase 3 - wire YAML config and CLI to the new transport - -1. Extend `ACPPoolServerConfig` in `src/agentpool_config/pool_server.py` with: - - `transport: Literal["stdio", "streamable-http"] = "stdio"` - - `host: str = "localhost"` - - `port: int = 8080` - -2. Update `ACPServer.from_config()` so YAML `pool_server.transport: streamable-http` resolves to `ACPWebSocketTransport(host, port)`. - -3. Update `src/agentpool_cli/serve_acp.py`: - - extend transport choices to `stdio | websocket | streamable-http` - - add `--host` and `--port` for the new transport - - keep `--ws-host` and `--ws-port` for legacy compatibility only - - emit a deprecation warning when `--transport websocket` is used - -4. Update `src/agentpool_cli/ui.py` so Toad helper startup migrates to the new transport unless there is a concrete compatibility reason not to. - -5. Re-export the new transport from `src/acp/__init__.py` if external imports rely on the public transport surface. - -Exit criteria: -- CLI and YAML both resolve to the same transport object model. -- Internal helper flows stop depending on the deprecated transport. - -### Phase 4 - tests and verification - -#### Unit coverage - -1. Transport normalization and dispatch - - `"streamable-http"` resolves correctly - - legacy `"websocket"` still resolves, but warns - -2. `ACPWebSocketTransport` defaults - - host default `localhost` - - port default `8080` - -3. Initialize guard behavior - - pre-initialize non-initialize request => `-32002` - - successful initialize flips state - - failed initialize does not flip state - -#### Integration coverage - -1. WebSocket connection to `/acp` succeeds. -2. Handshake includes `Acp-Connection-Id`. -3. Post-initialize normal ACP requests still flow through `AgentSideConnection`. -4. `WebSocketDisconnect` maps cleanly to end-of-stream behavior. -5. Connection shutdown closes `AgentSideConnection`. -6. `ACPServer` stop path triggers orderly server shutdown. -7. CLI transport selection and warnings behave as expected. -8. YAML config resolution produces the correct runtime transport. - -#### Verification commands - -Run at minimum: - -1. `uv run pytest tests/acp/test_streamable_http_transport.py tests/servers/acp_server/test_streamable_http_integration.py tests/cli/test_serve_acp_streamable_http.py` -2. `uv run --no-group docs mypy src/` -3. `uv run ruff check src/ tests/` -4. `uv run pytest` if targeted tests pass cleanly and change surface stays moderate. - -Also run `lsp_diagnostics` on all touched files before closing the work. - -## Sequencing notes for implementation - -1. Start with transport/runtime plumbing in `src/acp/transports.py`. -2. Add the agent-side initialize guard next, because its behavior shapes integration tests. -3. Then wire config and CLI. -4.

-## TL;DR - -> **Quick Summary**: Implement RFC-0034 to unify ACP and OpenCode model list sources, expose agent roles as switchable config options, and add `providers/*` ACP protocol support — enabling IDE users to select LLM providers and switch agent roles within a single ACP session. -> -> **Deliverables**: -> - `acp/schema/providers.py` — ProviderInfo, LlmProtocol, ProviderStatus type definitions -> - `acp_server/provider_router.py` — ProviderRouter with override/disable/capability support -> - `shared/model_utils.py` — `build_model_state_for_acp()` shared helper -> -

---- - -## Context - -### Original Request -Implement `docs/rfcs/draft/RFC-0034-acp-session-config-options-unified.md` — a 1257-line RFC proposing Option 2 (unified data source + complete Config Options alignment) across 4 implementation phases. - -### Interview Summary -**Key Discussions**: -- **Decision**: Option 2 (统一数据来源 + 完整 Config Options 对齐), 分 4 阶段 -- **Phase 0** (ACP Configurable LLM Providers): Add `providers/*` protocol methods, ProviderRouter, capability flag -- **Phase 1** (Shared Model List Logic): Extract `build_model_state_for_acp()` with configured-first, tokonomics-fallback -- **Phase 2** (Agent Role Config Option): Expose `agent_pool.all_agents` as `agent_role` config option with swap support -- **Phase 3** (OpenCode `/mode` fix): Dynamic `agent.get_modes()` instead of static `["default"]` -- **Pre-research spike**: pydantic-ai Provider injection investigation (Open Question #7, Wave 0) - -**Research Findings**: -- `shared/model_utils.py` exists — add `build_model_state_for_acp()` to existing file -- `AgentCapabilities` lacks `providers` field — needs adding -- `get_session_model_state()` currently tokonomics-first — needs inversion to configured-first -- `get_session_config_options()` is simple passthrough — easy to extend -- `set_session_config_option()` forwards to `agent.set_mode()` — needs `agent_role` branch -- `_session_agent_locks` already exists at `acp_agent.py:271` -- 17 ACP test files exist, using syrupy snapshots - -### Metis Review -**Identified Gaps** (addressed): -- `_session_agent_locks` was incorrectly reported missing — corrected (exists at acp_agent.py:271) -- Snapshot files are syrupy, not `.ambr` -- `AgentCapabilities.create()` has only 1 call site (`InitializeResponse.create()`) -- ProviderRouter thread safety needs `asyncio.Lock` -- Phase 0 must merge before Phase 1/2 branches -- Zed compatibility capped at smoke test -- Added missing acceptance criteria (error codes, agent_role position, /mode fallback) -- Added edge cases (tool call swap, provider collision, timeout) -

-### Definition of Done -- [ ] All 4 phases implemented and passing tests -- [ ] ACP snapshot tests re-baselined -- [ ] `agent_role` config option appears in `config_options` when `len(pool.all_agents) > 1` -- [ ] `providers/*` protocol methods respond correctly to `initialize(capabilities.providers=true)` -- [ ] `/mode` route returns dynamic modes from `agent.get_modes()` - -### Must Have -- ProviderRouter with override/disable/capability tracking -- Configured-first model state (tokonomics fallback) -- Agent role swap with lock protection -- `providers` capability flag in InitializeResponse -- Error responses for unknown provider / disable required provider (JSON-RPC -32602) -- All existing tests continue to pass - -### Must NOT Have (Guardrails) -- No ACP protocol schema modifications (only Python models) -- No OpenCode `/provider` REST API replacement -- No agent role persistence across sessions -- No runtime manifest reload -- No cross-session config synchronization -- No live provider routing for running sessions -- No full Zed IDE compatibility (keyboard shortcuts remain known limitation) -- No complete provider base URL canonical mapping -- No `SessionModelState` provider metadata extension -- No OpenCode `PATCH /config` semantic alignment with ACP `session/set_config_option` -

All four hook types (before turn, after turn, before tool use, after tool use) will work reliably for both native and ACP agents, fired from a single unified location instead of being scattered across two broken paths. - -**Why this approach:** The root cause is that hooks were wired through pydantic-ai's `Hooks` capability via a "stripping hack" that made them a no-op, and the SessionPool execution path never called them at all. By creating a `HookAwareTurn` mixin that fires hooks from `Turn.execute()` — the single choke point both native and ACP turns pass through — we fix the bug at its source and eliminate 400+ lines of workaround code. - -**What it will NOT do:** It won't change how individual hooks work (CallableHook, CommandHook, PromptHook stay the same). It won't change the deny>ask>allow priority logic. It won't add new hook types.

Create HookAwareTurn mixin and add hooks_fired to AgentRunContext - What to do / Must NOT do: - (a) Add `hooks_fired: set[str] = field(default_factory=set)` to `AgentRunContext` dataclass at `src/agentpool/agents/context.py:76`. Place it near line 94 (after `cancelled: bool = False`). **CRITICAL (Momus C2)**: Also add clearing logic — `hooks_fired` must be cleared at the START of each turn. In `RunHandle.start()` at `src/agentpool/orchestrator/run.py:253` (where `cancelled` is reset), add `run_ctx.hooks_fired.clear()`. In `_run_stream_once()` at `src/agentpool/agents/base_agent.py:1245`, add the same clearing at the start. Without this, turn 1's keys block turn 2+ hook firing. - (b) Create `HookAwareTurn` mixin class in `src/agentpool/orchestrator/turn.py` (after the `Turn` ABC, around line 73). - **CRITICAL (Metis G2.1 — MRO)**: `HookAwareTurn` is a pure mixin that does NOT inherit from `Turn`. Usage: `class NativeTurn(HookAwareTurn, Turn)` and `class ACPTurn(HookAwareTurn, Turn)`. This ensures `Turn`'s abstract methods are resolved by the host class, while `HookAwareTurn`'s concrete methods are mixed in. - **CRITICAL (Metis G7.2 — env access)**: `HookAwareTurn` must NOT access `self._agent` (ACPTurn doesn't have it). Instead, add an abstract property `_hook_env: ExecutionEnvironment | None` to `HookAwareTurn` that host classes must implement. `NativeTurn` returns `self._agent.env`, `ACPTurn` returns `self._agent_env` (new attribute, set from `ACPAgent.env` in `create_turn()`). - **CRITICAL (Momus M3 — agent_name/prompt sourcing)**: Add abstract properties `_hook_agent_name: str` and `_hook_prompt: str` to `HookAwareTurn`. `NativeTurn` returns `self._agent.name` and `str(self._prompts)`. `ACPTurn` returns `self._agent_name` and `str(self._prompts)`. These are needed to construct `HookInput` with `agent_name` and `prompt` fields. - **CRITICAL (Metis G1.1/G1.2 — hooks attribute)**: `HookAwareTurn` declares `_hooks: AgentHooks | None = None` as a class-level type annotation. Host classes set it in `__init__` via a new `hooks` parameter. - The mixin provides: - - `async def _fire_pre_turn_hooks(self) -> HookResult | None` — checks `"pre_turn" not in self._run_ctx.hooks_fired`, fires `self._hooks.run_pre_turn_hooks(agent_name=self._hook_agent_name, prompt=self._hook_prompt, session_id=self._run_ctx.session_id, env=self._hook_env)` with env from `self._hook_env`, adds `"pre_turn"` to `hooks_fired` set. Returns the `HookResult`. - - `async def _fire_post_turn_hooks(self, result: ChatMessage | None) -> HookResult | None` — checks `"post_turn" not in hooks_fired`, fires `self._hooks.run_post_turn_hooks(...)` with `result` and `duration_ms`, adds to set. **CRITICAL (Momus C1 — post_turn in finally)**: This method MUST be called in a `finally` block in the host class's `execute()` method, NOT after `_final_message` is set. Pass `self._final_message` (which may be `None` if the turn errored or was cancelled before completion). This ensures post_turn fires even on error/cancellation, per spec requirement: "post_turn hooks SHALL fire even if the turn was cancelled or errored." - - `async def _fire_pre_tool_hooks(self, tool_name, tool_input, tool_call_id: str | None = None) -> HookResult | None` — fires `self._hooks.run_pre_tool_hooks(...)`. Returns result for deny-checking. **CRITICAL (Momus M7)**: Guard key is `f"pre_tool_use:{tool_call_id}"` if `tool_call_id` is available, else `"pre_tool_use:{tool_name}"`. This prevents double-firing between ACP `request_permission()` and `ACPTurn.execute()` for the same tool call. - - `async def _fire_post_tool_hooks(self, tool_name, tool_input, tool_output, duration_ms, tool_call_id: str | None = None) -> HookResult | None` — fires `self._hooks.run_post_tool_hooks(...)`. Guard key is `f"post_tool_use:{tool_call_id}"` or `f"post_tool_use:{tool_name}"`. - - All methods are no-ops if `self._hooks` is None. - **CRITICAL (Metis G2.2 — deny behavior)**: When `_fire_pre_turn_hooks()` returns a result with `decision="deny"`, the host class's `execute()` must: (1) set `self._run_ctx.cancelled = True`, (2) construct an empty cancel message, (3) yield `StreamCompleteEvent(cancelled=True)`, (4) return early. This matches the existing pattern at `base_agent.py:1336-1347`. - Do NOT make HookAwareTurn inherit from Turn (it's a mixin). Do NOT call hooks directly in the mixin — always delegate to `self._hooks.run_*_turn_hooks()`. Do NOT change the Turn ABC. Do NOT use `getattr` or `hasattr` — use typed access via declared class variables and abstract properties. - Parallelization: Wave 1 | Blocked by: 1 | Blocks: 4,5,6,7 - References: - - `src/agentpool/orchestrator/turn.py:19-73` — `Turn` ABC class, `execute()` abstract method at line 36, properties at lines 47-73 - - `src/agentpool/agents/context.py:76-180` — `AgentRunContext` dataclass, `cancelled` at line 94, `run_id` at line 97, `session_id` at line 112 - - `src/agentpool/hooks/agent_hooks.py:30-186` — `AgentHooks` with `run_pre_turn_hooks()`, `run_post_turn_hooks()`, `run_pre_tool_hooks()`, `run_post_tool_hooks()` (renamed in Todo 1) - - `src/agentpool/hooks/base.py:20-68` — `HookInput` and `HookResult` TypedDicts - - `src/agentpool/agents/base_agent.py:1336-1347` — existing deny pattern: sets `run_ctx.cancelled = True`, creates cancel message, yields `StreamCompleteEvent(cancelled=True)` - Acceptance criteria: `uv run ruff check src/agentpool/orchestrator/turn.py src/agentpool/agents/context.py` passes. `uv run mypy src/agentpool/orchestrator/turn.py src/agentpool/agents/context.py` passes. - QA scenarios: - - Happy: `uv run pytest tests/ -k "context" -vv` passes - - Failure: `uv run mypy src/agentpool/orchestrator/turn.py` — no type errors - - Evidence: `.omo/evidence/task-3-unify-hook-system.txt` - Commit: Y | feat(hooks): add HookAwareTurn mixin and hooks_fired guard to AgentRunContext - -- [x] 4.

Write Phase 1 test suite (3-tier with smoke test matrix) - What to do / Must NOT do: Create comprehensive tests: - - **Unit** (`tests/hooks/test_hook_aware_turn.py`): Test `HookAwareTurn` mixin in isolation. Create a minimal host class that inherits `HookAwareTurn`, inject mock `AgentHooks` with mock `Hook` objects. Verify: (a) all 4 hooks fire in correct order, (b) `hooks_fired` set prevents double-firing, (c) hooks are no-op when `self._hooks` is None, (d) pre_turn fires before execute body, (e) post_turn fires in `finally` block even when execute raises, (f) `tool_call_id`-scoped guard keys prevent double-firing between `request_permission()` and `ACPTurn.execute()`. - - **Integration** (`tests/agents/native_agent/test_native_turn_hooks.py`): Test `NativeTurn` with `TestModel` from pydantic-ai. Verify hooks fire during turn execution with a tool call. Test that `pre_turn` → tool call (via `_ToolInterceptCapability`) → `post_turn` order is maintained. Verify tool hooks are NOT fired from `HookAwareTurn` for native agents (they're handled by `_ToolInterceptCapability`). - - **Integration** (`tests/agents/acp_agent/test_acp_turn_hooks.py`): Test `ACPTurn` with a fake `ACPClientProtocol` implementation. Verify hooks fire during ACP turn execution. Test permission blocking: a `deny` hook result blocks permission. Test advisory tool hooks fire during streaming. - - **E2E** (`tests/orchestrator/test_session_pool_hooks.py`): Test the SessionPool path via `RunHandle.start()` at `run.py:308`. This is the regression test — verify hooks fire when going through the session pool, which was the original bug. Create an agent, create a session, send a request, verify all hooks fired. **CRITICAL**: Test `hooks_fired` clearing between turns — send 2 requests in sequence and verify turn 2 hooks fire (not blocked by turn 1's `hooks_fired` keys). - - **CRITICAL (Momus M8 — smoke test matrix)**: Create `tests/hooks/test_hook_smoke_matrix.py` with a 16-cell test grid: {pre_turn, post_turn, pre_tool_use, post_tool_use} × {native standalone, native SessionPool, ACP standalone, ACP SessionPool}. Each cell verifies the corresponding hook type fires in the corresponding mode. Use `TestModel` for native, fake `ACPClientProtocol` for ACP.

Refactor AgentPoolACPAgent as terminal agent + remove legacy dual path + split ACPEventConverter +- [x] 22. Refactor AgentPoolACPAgent as terminal agent + remove legacy dual path + split ACPEventConverter What to do / Must NOT do: Refactor `AgentPoolACPAgent` to operate as terminal agent behind Conductor — respond to `initialize` (not `proxy/initialize`). Remove legacy `ACPSession.process_prompt()` dual path — consolidate to `ACPProtocolHandler.handle_prompt()`. Split `ACPEventConverter` refactoring into: (a) define proxy component interface, (b) extract stateless conversion functions, (c) implement proxy wrapper, (d) migrate callers. Verify `ACPProtocolHandler` (ProtocolEventConsumerMixin) works unchanged. Must NOT break existing ACP server. Must NOT remove ACPProtocolHandler.

Delete `ACPSessionState` remaining references. Delete `cast()` hack. Remove `use_conductor` feature flag (Conductor is only path). Simplify `acp_converters.py` — passthrough zero conversion. Remove `ToolManagerBridge` deprecated imports. Remove `AgentHooks` deprecation warnings (if any remain after unify-hook-system merge). Update AGENTS.md with proxy chain architecture. Add YAML config examples. Run full validation: `uv run pytest && uv run --no-group docs mypy src/ && uv run ruff check src/ && uv run ruff format --check src/`.

This fixes three critical defects: dead ACPTurn code, 50ms polling latency, and double event conversion in nested scenarios. Hooks, context injection, and tool providers become wire-level interceptors that can block before the terminal agent sees a message. - -**Why this approach:** The proxy chain RFD defines a Conductor that routes messages through a chain of proxies, each able to intercept and transform bidirectionally. This directly solves the double conversion problem (proxies pass through untouched when no interception needed) and provides a clean extension model. We wrap existing hooks as HookProxy components rather than rewriting them — preserving tested code while elevating it to wire-protocol level. - -**What it will NOT do:** It will not implement ACP remote transport, session fork, ratify the proxy chain RFD, refactor native agents to use proxy chains, support proxy hot-swap, or provide backward compatibility for the internal `_stream_events()` API. - -**Effort:** XL -**Risk:** High — implements against an unratified RFD with no Python reference implementation; depends on `unify-hook-system` branch merge; large refactoring scope (~4-5 weeks across 7 phases) -**Decisions to sanity-check:** D3 (ACPClientAdapter non-blocking design), D4 (HookProxy wraps existing hooks), D9 (HookProxy/HookAwareTurn coexistence via _hooks=None) - -Your next move: approve to start execution, or run a high-accuracy review first.

This is Phase 1 of a 2-phase MCP lifecycle redesign. - -**Why this approach:** The root cause is that session-scoped MCP state is scattered across 4 objects (`_toolset_cache`, `_session_connection_pool`, `_mcp_snapshot`, `AcpMcpConnectionManager._connections`) with no coordinated cleanup. The fix centralizes session-scoped state into `_SessionContext` on `MCPManager`, adds a per-session `asyncio.Lock` for concurrency-safe idempotent `cleanup_session()`, and wires cleanup into all 3 close paths (ACPSession.close, SessionController.close_session, WebSocket disconnect hook). All 8 design decisions were made through 3 rounds of Oracle + Gemini review. - -**What it will NOT do:** No changes to MessageNode base class, AgentPool registry, MCPResourceProvider model, or config API. No Phase 2 features (per-agent MCPManager removal, allow/block lists, pool-level MCP consolidation). No ACP v2 migration. - -**Effort:** Large -**Risk:** Medium — touches 7 source files across 3 subsystems (MCP manager, ACP server, session orchestrator), but all design decisions are made and codebase state is verified -**Decisions to sanity-check:** D4 (as_capability(session_id) API change — only caller is get_agentlet), D5 (reverse index at manager level instead of changing _session_streams key type), D6 (two-layer close-then-recreate in resume_session) - -Your next move: approve to start work, or run a high-accuracy review first.

Callers store the int key in `acp_connection_ids`. Affected: T1, T3, T6, T7, T8. -2. **GAP-3 (Critical)**: `AgentSideConnection` has no `connection_id` for `_connection_sessions` lookup. **Resolution**: Generate a UUID4 string for each WebSocket connection at accept time, store it on the `AgentSideConnection` instance (add a `connection_id: str` attribute set in `_handle_websocket_client()`), and use that as the key in `_connection_sessions`. The `on_disconnect` callback receives the `AgentSideConnection` and reads `.connection_id`. Affected: T24, T25, T26. -3. **GAP-4 (High)**: `_session_id` storage location undefined. **Resolution**: Use `run_ctx.session_id` in `get_agentlet()` (already available via `AgentRunContext`) instead of storing `self._session_id` on Agent. This avoids duplicating state. If `run_ctx` is None or `run_ctx.session_id` is None, fall back to `session_id=None` (global-only capabilities). Affected: T12, T16. -4. **GAP-5 (High)**: `connect_acp_mcp_server()` signature must gain `session_id: str` parameter. **Resolution**: Change signature to `connect_acp_mcp_server(self, server: AcpMcpServer, session_id: str) -> str`. Update call site at `session.py:478`. Affected: T8. -5. **GAP-7 (Medium)**: `_make_capability()` is a closure inside `as_capability()` and can't access per-session cache. **Resolution**: Pass `toolset_cache: dict[str, Any]` as a parameter to `_make_capability()` instead of accessing `self._toolset_cache` directly. When `cache=True`, pass `self._toolset_cache`; when `cache=False`, pass `ctx.toolset_cache`. Affected: T10. -6. **GAP-11 (High)**: Race condition — `cleanup_session()` can pop context while `as_capability()` reads it. **Resolution**: `as_capability()` acquires `ctx._cleanup_lock` before reading the session context (shared lock via `asyncio.Lock` — but `asyncio.Lock` is exclusive, not shared). Alternative: `as_capability()` catches `KeyError` on `_session_contexts` lookup and falls back to global-only. **Chosen**: Catch `KeyError` fallback approach — simpler, no lock contention. Affected: T10. -7. **GAP-12 (High)**: `AcpMcpConnectionManager.cleanup_session()` has no lock. **Resolution**: Add `_cleanup_lock: asyncio.Lock` to `AcpMcpConnectionManager.__init__`. `cleanup_session()` acquires it. Double-cleanup from `MCPManager.cleanup_session()` + direct call is idempotent (pop from `_session_connections` returns None on second call). Affected: T7. -8. **GAP-15 (High)**: Task 7.5 manual test violates zero-user-intervention. **Resolution**: Replace with automated integration test using mock ACP client. Test creates a mock WebSocket connection, sends ACP messages, simulates disconnect, reconnects, and verifies MCP tools work. Affected: T33. -9. **GAP-14 (Medium)**: Resume after close — closed session re-opening. **Resolution**: `SessionController.close_session()` marks session as closed in store (line 830-832) but `_get_or_create_session_locked()` creates fresh `SessionState` if not in `_sessions` dict (which was popped at line 933). The store's "closed" flag is informational — a new `SessionState` is created. This is validated by the existing resume flow. No change needed, but T20 acceptance criteria must verify this explicitly. - -## Verification strategy -> Zero human intervention - all verification is agent-executed. -- Test decision: tests-after (implementation first, tests in same todo) + pytest -- Evidence: .omo/evidence/task--fix-mcp-session-lifecycle. -- Lint: `uv run ruff check src/` — zero errors -- Types: `uv run --no-group docs mypy src/` — zero errors on changed files -- Tests: `uv run pytest tests/mcp_server/ tests/agentpool_server/acp_server/ -v` -- Unit marker: `uv run pytest -m unit` - -## Execution strategy -### Parallel execution waves -> Target 5-8 todos per wave.

Replace with: (1) if session exists, call `SessionController.close_session(session_id)` first (handles RunHandle lifecycle with 10s timeout + cancel, calls `agent.mcp.cleanup_session()` via T15, calls `agent.__aexit__()`), (2) then call `ACPSession.close()` for ACP-specific cleanup (acp_env, signals, prompts — also calls `cleanup_session()` via T15, but idempotent via D8 lock), (3) remove from `_acp_sessions`, (4) proceed to create fresh session. Fallback: if `SessionController` is unavailable (tests), call `ACPSession.close()` only. Must NOT skip the `SessionController.close_session()` call when it's available — it handles active runs.

Add `on_disconnect` parameter to `_handle_websocket_client()` and call in `ConnectionClosed` handler - What to do / Must NOT do: Add `on_disconnect: Callable[[AgentSideConnection], Awaitable[None]] | None = None` parameter to `_handle_websocket_client()` at `transports.py:355`. **Metis GAP-3 resolution**: Generate a UUID4 string for each WebSocket connection at accept time, store it as `conn.connection_id: str` attribute on the `AgentSideConnection` instance (set right after creation at line 376). In the `ConnectionClosed` exception handler (line 412), call `await on_disconnect(conn)` BEFORE `conn.close()` in the finally block (line 414). The callback reads `conn.connection_id` to look up sessions. If `on_disconnect` is None, skip the call (backward compat). Must NOT make `on_disconnect` a required parameter. Must NOT call `on_disconnect` after `conn.close()`. - Parallelization: Wave 6 | Blocked by: T15 | Blocks: T25, T26, T27 - References: `src/acp/transports.py:355-428` (_handle_websocket_client), `transports.py:412` (ConnectionClosed catch), `transports.py:414-428` (finally block) - Acceptance criteria: `uv run pytest tests/ -k "websocket" -v` — existing WebSocket tests pass. `uv run ruff check src/acp/transports.py` passes. `uv run --no-group docs mypy src/acp/transports.py` passes. - QA scenarios: (happy) Disconnect triggers `on_disconnect` callback with connection object.

Add `_connection_sessions` to ACPSessionManager and implement `close_all_sessions_for_connection()` - What to do / Must NOT do: (1) Add `_connection_sessions: dict[str, set[str]]` (connection_id → session_ids) to `ACPSessionManager.__init__` (after `_acp_sessions` at line 45). **Metis GAP-3 resolution**: The `connection_id` is the UUID4 string generated and stored on `AgentSideConnection.connection_id` (from T24). Populate `_connection_sessions` when sessions are created/resumed — add `session_id` to `_connection_sessions[connection_id]` set. The `connection_id` must be passed from the `Client` object or from the `AgentSideConnection` when creating the session. Check `ACPSessionManager.create_session()` to see how `client: Client` is received and how to access the underlying connection's `connection_id`. (2) Implement `async close_all_sessions_for_connection(self, connection_id: str) -> None` — iterates sessions for the connection. For each session: call `SessionController.close_session(session_id)` first (RunHandle lifecycle with timeout + cancel), then call `ACPSession.close()` for ACP-specific cleanup. Both must be called — SessionController handles RunHandle + agent lifecycle, ACPSession.close() handles ACP-specific state. Remove the connection entry from `_connection_sessions` after all sessions are closed. Must NOT skip SessionController.close_session() when available.

Wire `on_disconnect` callback in server setup - What to do / Must NOT do: In the server setup that creates `_handle_websocket_client()` call (search for where `_handle_websocket_client` is called — likely in `ACPWebSocketTransport` or a server module), pass a callback that calls `ACPSessionManager.close_all_sessions_for_connection(connection_id)`.
