What problem does it solve? Before archiving a change, teams need confidence that the implementation actually matches the planned specs, tasks, and design. This Skill automates that verification by cross-checking code against OpenSpec change artifacts and producing a structured report. ## Core Features & Use Cases - Three-Dimension Verification: Checks completeness (task and spec coverage), correctness (requirement implementation and scenario coverage), and coherence (design adherence and code pattern consistency). - Prioritized Issue Reporting: Generates a markdown report grouping findings into CRITICAL, WARNING, and SUGGESTION issues, each with actionable recommendations and file references. - Graceful Degradation: Adapts verification depth based on available artifacts, verifying only tasks when specs or design documents are missing. - Use Case: After finishing implementation of a spec-driven change, run this Skill to confirm all tasks are checked off, every requirement has corresponding code, and the design decisions were followed before archiving the change. ## Quick Start Ask the assistant to verify that the implementation of a specific OpenSpec change matches its specs, tasks, and design before archiving.
