audit-product-docs

Validate the repo's user-facing / product / contributor docs against the code (settings/config names + defaults, command/action IDs, file paths, schedule/cron formats, tool/function names), patch drift in place, and add new docs only for user-visible features that aren't covered. Use when the user asks to "audit the docs", "review the docs", "validate docs against the code", "sync docs with the codebase", "find doc gaps", or similar. Covers USER-FACING docs — the sibling audit-design-docs skill covers internal design/architecture docs. Writes drift fixes + new docs to the working tree and stops; the caller (a human, or the daily-update meta-skill) is responsible for committing and opening a PR.
