What problem does it solve? Execution plans often drift from reality: they reference wrong file paths, renamed symbols, nonexistent tests, or commands the repository does not support. This Skill audits an existing ExecPlan against the actual codebase and rewrites it in place so it is accurate, complete, and executable without changing its original intent. ## Core Features & Use Cases - Evidence-grounded verification: Deep-reads every file, symbol, payload, migration, and command the plan references and flags mismatches with reality. - Lifecycle and invariant tracing: Follows durable state through create, execute, retry, reconcile, reopen, and cleanup paths, checking that guard fields like revisions or checkpoint cursors survive every mutating path. - In-place plan rewrite: Fixes wrong paths and signatures, adds missing lifecycle coverage and compatibility notes, and appends a revision note while preserving completed progress and history. - Use Case: Before handing an ExecPlan to an implementer, run this Skill to confirm every referenced helper, test, and command actually exists and that retry and recovery paths preserve the same invariants as the main path. ## Quick Start Ask the agent to improve the ExecPlan at a specific path, for example: review and improve the ExecPlan in .agent/plans/add-retry-logic.md against the current repository code.
