What problem does it solve? Plans that pass automated format checks can still fail in execution: symbols nobody creates, stale file paths, unowned acceptance criteria, or goals with no covering task. This Skill performs a correctness review of a Plan before execution, catching defects that regex-based form validators cannot detect. ## Core Features & Use Cases - Three-question review model: Q1 checks whether plan parts fit together (symbol producers, AC ownership, dependency order), Q2 verifies every factual claim against the repository at a stated revision, Q3 confirms the plan actually delivers the stated goal without silent scope shrinkage. - Structured verdicts and reports: Produces PASS, REVISE, or BLOCK verdicts with severity-calibrated findings (Blocker, Warning, Info, Unverified), each citing both the plan location and the contradicting reality. - Use Case: Before approving a risky migration or cross-module refactoring plan, ask for a plan review to catch a task that references an error code no task registers, or a premise about the codebase that is no longer true. ## Quick Start Ask the agent to review the plan at a given path before execution, for example: review this implementation plan and tell me whether it will work if followed literally.
