What problem does it solve? Discussion-to-specification handoffs in spec-kit projects can carry stale evidence, missing fields, or integrity failures that silently corrupt downstream planning. This Skill provides a structured review process for the handoff-to-specify.json contract so problems are caught before the contract becomes ready or is consumed. ## Core Features & Use Cases - Structured Contract Review: Walks a defined review order covering goal and scope, context boundary, evidence authority, selected direction, success criteria, dependencies, and consumer eligibility gates. - Three-Way Verdicts: Returns approve, request-changes with exact JSON refs, or blocked with cause, owner, and safe retry conditions. - Digest Integrity Enforcement: Requires recomputing the protected digest after changes and rejects confirmation of stale revisions. - Use Case: When sp-discussion asks for final review or sp-specify reports a contract integrity failure, run this review to validate .specify/discussions/<slug>/handoff-to-specify.json and produce a clear verdict with required corrections. ## Quick Start Review the discussion handoff contract for the current feature slug and tell me whether it is approved, needs changes, or is blocked.
