What problem does it solve? Verification skills and feature maps drift out of sync with the product as code changes, leaving stale coverage claims and untrustworthy evidence. This Skill performs an explicit, on-request maintenance pass that re-validates mapped features and updates only the verification artifacts. ## Core Features & Use Cases - Drift Detection: Reads the current Feature Map, inspects source changes, routes, roles, and fixtures, then identifies where verification coverage no longer matches reality. - Role-Separated Live Verification: Sends neutral execution steps to a Computer Use runner while keeping the acceptance rubric private to an independent judge, using deterministic before/after probes. - Scoped Updates: Updates only the verification skill, harness, feature map, or private evidence, and reports clean, changed, or blocked outcomes without touching product code. - Use Case: After a release changes several dashboard routes, ask for a verification maintenance pass to re-run affected flows, refresh the feature map, and store new evidence under the private verification directory. ## Quick Start Ask the agent to run a verification maintenance pass on the repository's existing verify-product skill and refresh the feature map for the changed routes.
