What problem does it solve? After a feature is built, teams need structured proof that it actually works before opening a PR. This Skill runs targeted tests, surface-appropriate regression checks, and verifies every acceptance criterion from the feature plan, producing a documented validation report instead of ad-hoc manual checking. ## Core Features & Use Cases - Acceptance Criteria Verification: Checks each criterion in the feature plan and marks it VERIFIED, FAILED, or CANNOT VERIFY with evidence. - Surface-Aware Testing: Classifies the feature as browser/UI, service/API, library/CLI, or mixed, then runs proportionate targeted and regression tests for that surface. - Validation Report Generation: Writes a structured report to docs/features/ with test results, coverage gaps, regressions, and a ship/no-ship recommendation, then appends a Validation section to the feature plan. - Use Case: After execute-feature finishes a new API endpoint, run this Skill to confirm all acceptance criteria pass, detect regressions in the integration suite, and produce a READY TO SHIP report before prepare-pr. ## Quick Start Use the validate-feature skill to verify the current feature against its plan and produce a validation report.
