## Intake summary
既存 Ticket を確認し、同目的の未完了重複は見当たりません。要件は Tool 実行 API に `ToolExecutionContext` を導入し、`call_id` / response-local `batch_id` / `call_index` を Tool 実装へ渡すことです。Worker は従来どおり approved tool calls を並列実行し、resource scheduling policy は持たないこと、old Tool API 互換層を長期維持しないこと、Interceptor / hook に lock lifecycle を持たせないことが binding decision です。実装側には `batch_id` 生成方式や session log への記録有無の裁量があります。関連し得る Ticket として `00001KTNS9B50` は response 単位の batching analytics であり、目的が異なるため重複ではありません。リスク/レビュー焦点は public API 変更、Worker tool execution path、Interceptor/hook 意味論、並列実行維持、既存 built-in tools の一括移行です。受け入れ条件と validation が明確なため implementation_ready と判断します。

<!-- event: state_changed author: orchestrator at: 2026-06-09T10:03:41Z from: queued to: inprogress reason: orchestrator_acceptance field: state -->
## State changed
Accepted queued implementation after reading the Ticket and current workspace state. This is a core tool execution API migration and should land before changing individual tool outputs such as TicketList. No active implementation worktree exists, and the workspace record updates were committed before acceptance.

## Decision
Routing decision: implementation_ready
Evidence checked:
- Ticket body and Intake summary.
- Current queued set: `00001KTNVGT8G`, `00001KTNSA2K0`, and `00001KTNS1AA8`.
- Current workspace/worktree state after committing queued record updates: main workspace clean, no active implementation worktree.
- Relation/order context: `TicketList` output slimming should wait for this core tool execution API migration.
Reason:
- The Ticket has clear implementation requirements: introduce `ToolExecutionContext`, pass it through Tool execution, and move context-dependent path/working-directory/backend access out of static Tool definitions where appropriate.
- It is a lower-level API migration that should land before individual tool output/UX changes.
- No concrete missing decision remains requiring return to planning.
IntentPacket:
Intent:
- Pass a `ToolExecutionContext` into Tool execution so tool behavior can depend on runtime context without encoding runtime-dependent data in static tool definitions.
Binding decisions / invariants:
- Static Tool definitions/schemas remain static and reusable.
- Runtime-dependent values such as cwd/workspace context/backend handles should flow through execution context where appropriate, not through schema metadata or global mutable state.
- Existing tool behavior must remain compatible unless a tool explicitly needs the new context.
- Keep capability/authority checks explicit and typed; do not use `ToolExecutionContext` as an unstructured escape hatch.
- Do not weaken scope, host-authority, Ticket backend, or web/network safety boundaries.
- Avoid broad speculative refactors beyond the execution-path migration required for this Ticket.
- Update built-in tools/tests that need context, especially file/path/Ticket/backend-sensitive surfaces.
- Preserve LLM-facing tool names and schemas unless a specific schema change is required.
Implementation latitude:
- Coder may choose exact `ToolExecutionContext` fields and lifetimes if they keep ownership/thread-safety practical and avoid leaking runtime/session-private data into static schemas.
- Coder may introduce default/empty context helpers for tests and tools that do not need context.
- If a subset of tools must be migrated first, keep a coherent buildable boundary and report remaining follow-up explicitly.
Escalate if:
- The change requires redesigning the whole ToolRegistry/plugin system.
- Context fields would need to carry raw Worker/history/session mutable access.
- Authority checks cannot remain explicit and typed.
- Too many unrelated tool schema/output changes become necessary.
Validation:
- Focused Tool trait/ToolRegistry tests for context passing.
- Focused tests for context-sensitive built-in tools such as Ticket/backend/path tools if affected.
- Existing tool schema/name tests.
- `cargo fmt --check`.
- `git diff --check`.
- `cargo run -q -p yoi -- ticket doctor`.
- `cargo check --workspace`.
- `nix build .#yoi`.

## Implementation report
Implementation routing started.
Worktree/branch:
- Worktree: `.worktree/tool-execution-context`
- Branch: `tool-execution-context`
- Base/routing commit: `b21fab8 ticket: route tool execution context`
Spawned sibling Coder Pod:
- `coder-tool-execution-context`
- Scope: non-recursive read on parent workspace root plus recursive write limited to the child worktree.
Routing context:
- This is the active implementation work.
- `00001KTNSA2K0` (`TicketListの出力を軽量化する`) is intentionally left queued until this core Tool execution API migration lands.
- `00001KTNS1AA8` is also left queued for capacity/sequencing while this core migration is active.

## Implementation report
Coder implementation completed and is ready for sibling review.
Coder Pod:
- `coder-tool-execution-context`
- Commit: `d8aed7befe6ff739cbee1b49221d3b8be35a57d7 tool: add execution context`
- Worktree status before review: clean branch `tool-execution-context`
- Stopped after collecting output to reclaim delegated worktree scope.
Selected design:
- Added `llm_worker::tool::ToolExecutionContext` with `call_id`, `batch_id`, and `call_index`.
- `batch_id` is Worker-local monotonic (`tool-batch-{n}`) and shared across one `execute_and_commit_tools` batch.
- `call_index` is 0-based order from the LLM-returned tool call array.
- `call_id` is synchronized to any pre-interceptor-mutated tool call id before execution/post context.
Implementation summary:
- `Tool::execute` and `ToolServer::call_tool` now receive `ToolExecutionContext`.
- Worker assigns context while preserving parallel approved tool execution via `join_all`.
- `ToolCallInfo` / `ToolResultInfo` expose context.
- skipped / synthetic / post-tool paths have context available.
- Built-in tools, Ticket tools, Memory tools, Pod tools, test fixtures, and macro-generated Tool implementations were migrated.
- `llm-worker-macros` excludes `ToolExecutionContext` parameters from JSON schema and supplies them from execution context.
- Added direct/default context helpers for low-level direct tests; Worker path passes explicit batch context.
Validation reported passed:
- `cargo test -p llm-worker --test tool_macro_test`
- `cargo test -p llm-worker --test parallel_execution_test`
- `cargo test -p llm-worker`
- `cargo test -p tools -p ticket`
- `cargo test -p memory`
- `cargo test -p pod --tests --no-run`
- `cargo test --workspace --no-run`
- `cargo fmt --check`
- `git diff --check`
- `cargo check --workspace`
- `cargo run -q -p yoi -- ticket doctor`
- `nix build .#yoi`
Residual notes:
- `batch_id` is not globally durable.
- Resumed pending tool calls receive a fresh execution batch id.
- No scheduling, serialization, per-resource locks, same-file queueing, or `parallel_tool_calls=false` equivalent was added.

## Review: approve
## Review result: approve
Reviewed commit `d8aed7befe6ff739cbee1b49221d3b8be35a57d7` on branch `tool-execution-context`.
Evidence:
- `ToolExecutionContext` is added as a small value object with `call_id`, `batch_id`, and `call_index`, and `Tool::execute` / `ToolServerHandle::call_tool` now receive it.
- Worker assigns `tool-batch-{n}` once per `execute_tools` invocation, enumerates model-returned tool calls for 0-based `call_index`, synchronizes `call_id` after pre-interceptor call mutation, and passes the context into execution and post interceptors.
- Approved calls are still executed through `join_all`; no serial/resource scheduling policy, same-file mutex/queue, `parallel_tool_calls=false`, or conflict solver was introduced.
- Interceptor info structs expose context only as metadata; no lock/permit lifecycle is introduced into interceptors.
- Macro generation filters `ToolExecutionContext` out of JSON arguments while passing it as a non-schema parameter; built-in/manual tools were migrated to the new signature and no old `Tool::execute(input_json)` implementation remains.
- Context contains only response-local ids/order and does not expose Worker/history/session mutable handles; existing scope/host-authority/Ticket/web checks remain in the migrated tool bodies.
Focused validation run by reviewer:
- `cargo test -p llm-worker --test parallel_execution_test test_tool_execution_context -- --nocapture` — passed (3 tests).
- `cargo test -p llm-worker --test parallel_execution_test test_parallel_tool_execution -- --nocapture` — passed.
- `cargo test -p llm-worker --test tool_macro_test -- --nocapture` — passed (9 tests).
- `cargo check -p llm-worker -p tools -p ticket` — passed.
- `git diff --check && cargo fmt --check` — passed.
- `cargo run -q -p yoi -- ticket doctor``doctor: ok`.
Residual risk:
- `batch_id` is Worker-local (`tool-batch-{n}`), not a durable globally unique id across process/session reconstruction. That matches the implementation report and is acceptable for this ticket, but should not be treated as persistent cross-session identity.

## Review: approve
Review result: approve
Evidence:
- `ToolExecutionContext` carries `call_id`, `batch_id`, and `call_index` as response-local execution context.
- `Tool::execute` / `ToolServerHandle::call_tool` receive context.
- Worker assigns one `tool-batch-{n}` per tool batch and 0-based `call_index` in LLM-returned tool-call order.
- `call_id` is synchronized after pre-interceptor mutation before tool execution and post-interceptor reporting.
- Approved tool calls continue to execute in parallel with `join_all`; no serial policy, resource scheduler, same-file mutex, mutation queue, or `parallel_tool_calls=false` equivalent was introduced.
- `ToolCallInfo` / `ToolResultInfo` expose context as metadata without lock/permit lifecycle.
- Macro-generated tools treat `ToolExecutionContext` as a non-schema parameter, not an LLM JSON argument.
- Built-in/manual tools are migrated to the new API and the old `Tool::execute(input_json)` implementation pattern is not retained as a compatibility surface.
- Context carries response-local identity/order only and is not Worker/history/session mutable access; scope, host-authority, Ticket, and web safety boundaries are not weakened.
Reviewer validation:
- `cargo test -p llm-worker --test parallel_execution_test test_tool_execution_context -- --nocapture`
- `cargo test -p llm-worker --test parallel_execution_test test_parallel_tool_execution -- --nocapture`
- `cargo test -p llm-worker --test tool_macro_test -- --nocapture`
- `cargo check -p llm-worker -p tools -p ticket`
- `git diff --check && cargo fmt --check`
- `cargo run -q -p yoi -- ticket doctor`
All passed. Residual note: `batch_id` is Worker-local (`tool-batch-{n}`), not a durable/global identity across process/session reconstruction. This is acceptable for this Ticket but should not be treated as a persistent external artifact key without a future design.
