What problem does it solve? Planning documents often drift from reality: file paths that don't exist, acceptance criteria without test coverage, or plan steps that contradict the proposed solution. This Skill reviews task planning docs (markdown or HTML) against the actual codebase and leaves structured inline comments so authors can fix issues before implementation begins. ## Core Features & Use Cases - Codebase-grounded verification: Checks that referenced files, types, functions, and commands actually exist and match the described signatures. - Cross-document consistency checks: Traces every acceptance criterion to test coverage and plan steps, and validates epic linkage across documents. - Structured comment threads: Inserts append-only review comments with priority levels (P1/P2/P3) in markdown comment blocks or HTML <pd-thread> elements, without modifying the author's content. - Use Case: After drafting a plan for task 042, ask for a review to catch a wrong file path in the solution tab and a missing test for one acceptance criterion before handing the task to an executor. ## Quick Start Ask the agent to review the planning docs for task 042 and leave inline comments on any problems it finds.
