+## Plan
+
+Review dispatch:
+- Spawned Reviewer Pod `yoi-reviewer-00001KVHR3WSD-r1` against implementation branch `impl/00001KVHR3WSD-mcp-tools-call`。
+- Review target commit: `9a245403 mcp: execute stdio tool calls`。
+- Review baseline: `92432ad7`。
+- Reviewer task focuses on permission-before-call, ordinary Tool result/history path, `isError` vs protocol error semantics, output bounds/untrusted content, lifecycle redaction/shutdown preservation, no resources/prompts/list_changed/sampling/elicitation scope creep, tests, and package validation。
+- Reviewer is instructed not to edit source, commit, merge, close the Ticket, or use TicketReview directly; it will report verdict/evidence back to Orchestrator。
