+Implemented, reviewed, merged, and validated.
+
+Summary:
+- Added `ToolExecutionContext` with `call_id`, `batch_id`, and `call_index`.
+- Changed Tool execution APIs so `Tool::execute` / `ToolServer::call_tool` receive execution context.
+- Worker assigns one response-local batch id per approved tool-call batch and preserves LLM-returned call order with `call_index`.
+- Approved tool calls still execute in parallel; no scheduler, same-file mutex, mutation queue, conflict solver, or `parallel_tool_calls=false` behavior was added.
+- `ToolCallInfo` / `ToolResultInfo` expose context metadata.
+- Macro-generated tools can receive `ToolExecutionContext` as a non-schema parameter; context is not exposed as an LLM JSON argument.
+- Built-in tools and tests were migrated to the new API.
+
+Implementation:
+- Coder commit: `d8aed7b tool: add execution context`
+- Reviewer approved with no blocking findings.
+- Merge commit: `4744548 merge: add tool execution context`
+
+Validation after merge:
+- `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 fmt --check`
+- `git diff --check`
+- `cargo run -q -p yoi -- ticket doctor`
+- `cargo check --workspace`
+- `nix build .#yoi`
+
+Residual note:
+- `batch_id` is Worker-local and not a durable/global external artifact key.

 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.
