What problem does it solve? After implementation work finishes, teams lack a rigorous, change-wide quality gate that reconciles actual code against the original proposal, tasks, and specs before archiving. This Skill performs final verification with mandatory evidence so changes cannot silently ship unverified. ## Core Features & Use Cases - Change-Wide Verification: Reconciles the full implemented change against proposal.md, tasks.md, spec.md, and design.md, not just the latest batch. - Config-Driven Command Plan: Derives test, build, lint, and typecheck commands from openspec/config.yaml and records results, skips, and blockers. - Compliance Matrix & Verdict: Produces verify-report.md with a compliance matrix, evidence log, severity-rated issues, and a pass, pass_with_warnings, or fail verdict with an archive gate. - Use Case: After sdd-apply completes a feature change, run final verification to confirm all acceptance criteria pass, then route the change to archive or back for correction. ## Quick Start Run final verification on the current change and write verify-report.md with the verdict and next recommended action.
