features-documentation

Ensures all user-facing feature changes are reflected in features documentation. When documentation drift is detected, work pauses until documentation is synchronized.

Core principle: Users must be able to discover and understand all features. Undocumented features don't exist to users.

Announce at start: "I'm using features-documentation to verify feature documentation sync."

Use when user-facing features change. Ensures features documentation is updated. Pauses work if documentation has drifted, triggering documentation-audit skill. Source: troykelly/codex-skills.
