Maintain a verification skill

A skill named in bold or in backticks, or run as /<name>, is the file ../<name>/SKILL.md beside this skill's directory, and a principle named without its prefix is ../principle-<name>/SKILL.md. Read the file and follow it. Most pstack skills are user-only, so your skill tool cannot load them. Every subagent is a Rex worker pane: spawn, wait and close it per ../rex-subagents/SKILL.md, with the defaults in the Subagents section of ../poteto-mode/SKILL.md.

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).
