What problem does it solve? Project briefs and PRDs often contain hidden gaps, unresolved decisions, contradictions, and vague acceptance criteria that only surface during implementation, causing rework and misaligned expectations. This Skill systematically reviews requirements documents before planning begins and converts every finding into an answerable question or decision. ## Core Features & Use Cases - Gap and Contradiction Detection: Identifies missing requirements, unresolved decisions, hidden assumptions, and conflicts between goals, scope, and constraints, each traced to source evidence. - Acceptance Criteria Verifiability Check: Flags subjective or untestable criteria and proposes testable rewrites only when the source supports them. - Prioritized Readiness Verdict: Classifies findings as blocker, high, medium, or low, and issues a readiness verdict scoped to a named next stage. - Use Case: Before handing a feature PRD to engineering, run this Skill to receive a findings table, a decision queue with owners, and a clear verdict on whether the document is ready for estimation. ## Quick Start Review the attached product brief for missing requirements, contradictions, and untestable acceptance criteria, then give me a prioritized findings table and a readiness verdict.
