docsync-setup

Project-scoped doc-staleness tracker. Installs three project-local hooks that watch which .md docs you touch, then nag (once, at end of turn) when a touched doc is stale by date. Source of truth = each doc's own frontmatter. Replaces brewdoc:auto-sync.

Prompt contract

Position 1 of $ARGUMENTS is a free-form prompt (RU/EN) — modes and flags are optional and may follow in any order. Nobody types keys: resolve mode + scope FROM the prompt.
