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 20260609-085148-001 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。

State changed

Intake により要件・非目標・受け入れ条件・レビュー焦点が routing 可能な状態で確認されたため、planning から ready にします。

---

State changed

Ticket を workspace-panel が queued にしました。

---

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: 20260609-093050-001, 20260609-085212-001, and 20260609-084725-001.
• 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.
• 20260609-085212-001 (TicketListの出力を軽量化する) is intentionally left queued until this core Tool execution API migration lands.
• 20260609-084725-001 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.
