Diff-driven documentation surface classifier. Given a diff (staged, branch, or range), reads the project's indexed ## Documentation surfaces table from CLAUDE instructions, matches the diff against it, and emits a structured list of proposed edits. Two modes: maintenance (commit flow — stale/incomplete only, never suggests new pages) and authoring (/documentation explicit — full discovery, gap detection, content generation). Auto-fires on "doc this change", "what surfaces does this touch", "doc impact for this diff", "what needs documenting". Also invoked by /documentation (authoring mode) and by ship verbs (maintenance mode, between stage and signals). Boundary: for raw prose drafting (README intro, guide narrative), atomic-writing owns. This skill owns diff-driven surface impact and content generation for stale/incomplete docs.
