What problem does it solve? Plans and PRDs read convincingly by default, hiding ambiguity, unverified assumptions about the codebase, and phases that only work in the author's head. This Skill performs a logical review of plan-shaped documents with the human reviewer in the loop, verifying claims against the real codebase before anyone commits to the plan. ## Core Features & Use Cases - Eight-dimension review: problem clarity, ambiguity, phase structure, acceptance criteria, reality check against the codebase, coherence with normative docs, scope/YAGNI, and impacts. - Visual dossier: generates a Mermaid phase/dependency graph, a requirement-to-phase-to-criterion traceability matrix, and an assumption map marking each codebase claim as verified, unverified, or false. - Interactive walkthrough: closed-menu questions, one section at a time, with finding triage in EDIT mode (apply fixes) or QUESTIONS mode (build an author question list). - Use Case: Before decomposing a PRD into tasks, run this Skill to confirm every file and class the plan references actually exists, catch phases that fail the cancellation test, and produce a verdict of ready to commit, needs revision, or needs discussion. ## Quick Start Ask the agent to review your plan document, for example: walk me through this PRD at docs/prd-auth.md and check its claims against the codebase.
