--- name: feature-doc description: Document a shipped feature from the live app: real screenshots and a screen recording, a docs article with how-to and use cases, verified before publish --- Read `.claude/skills/feature-doc/SKILL.md` and execute it exactly as written; that file is the authoritative playbook. Then follow `.agents/rules/cog.md`. Antigravity substitution: where the playbook delegates to a `.claude/agents/` worker, invoke `.agents/agents/.md` via `invoke_subagent` instead.
