What problem does it solve? Verification skills and their feature maps drift out of sync with the application as the product changes, causing stale documentation, broken harnesses, and untested features. This Skill runs a periodic maintenance pass that re-verifies every feature from source and live execution, then ships only proven corrections. ## Core Features & Use Cases - Parallel source audit: Launches one read-only subagent per feature file to explain how each feature works from source and flag likely documentation drift with citations. - Live verification pass: Drives every feature in a real running session (server, UI, or CLI) with strict health-check, evidence-preservation, and cleanup invariants. - Scoped corrections: Edits only the verification skill's own directory and ships at most one PR of proven doc, harness, or map fixes, reporting product bugs instead of patching over them. - Use Case: After a month of product changes, run the maintenance pass on your project's verify skill to find that two features were renamed, one harness script broke, and the map missed a new settings page — then receive a single PR with the proven corrections. ## Quick Start Ask the AI to run /maintain-verification-skill to audit the project's verification skill and feature map against the current application.
