# Maintain a verification skill A feature map rots the moment the app changes. This skill is the upkeep loop for a skill generated by `/create-verification-skill` (or any project-local verification skill with a feature map). The unit of rigor is the feature, not every sentence: cover every feature file from source and exercise every feature live, without terminalising every bullet. ## Outcomes Pick one, and say which: - **clean** — every feature got source and live coverage; nothing worth shipping. No branch, no PR. - **changed** — one PR ships proven doc, harness, or map corrections. - **blocked** — coverage could not finish or a proven fix could not ship safely. Say exactly what blocked it. ## Edit scope Only edit the verification skill's own directory (its SKILL.md, features/, and any harness scripts it owns). Never edit product code during a run: a behavior the map describes that the app no longer does is either doc drift (fix the map) or a product regression (report it, don't paper over it in docs). ## Pass 0. **Locate the target.** Find the verification skill to maintain: the project-local skill whose body has launch/drive sections and a feature map (usually `.harness/skills/verify-*/`). Several candidates → ask which one; none → stop and point at `/create-verification-skill` instead of inventing a target. 1. **Index hygiene.** Read the feature map README and glob its sibling files. Fix missing, extra, duplicate, or dead entries. Lightweight; no generated inven
