What problem does it solve? Technical specs often contain unverified claims about the codebase, missing risk analysis, or incomplete acceptance criteria that mislead implementation. This Skill dispatches an independent reviewer to validate a spec against the actual repository before development begins. ## Core Features & Use Cases - Five-dimension review: Scores completeness, feasibility, risk assessment, code consistency, and test strategy with calibrated severity levels. - Independent code verification: The reviewer greps and reads the actual repository to confirm that referenced files, functions, flags, and commands exist and behave as described. - Structured gate verdict: Produces a fixed-format report ending in ✅ Mergeable or ⛔ Needs revision, with deferred non-blocking findings logged via [NIT_DEFERRED] lines. - Use Case: Before implementing a feature, run the review on docs/features/2-auth-redesign.md to catch a spec that references a nonexistent config flag and lacks a rollback plan. ## Quick Start Ask the assistant to review the technical spec at docs/features/2-auth-redesign.md for completeness, feasibility, and consistency with the codebase.
