Use when writing or updating any doc of record in this dotfiles repo -- README.md, repo CLAUDE.md, claude/CLAUDE.md, claude/operating-principles.md, codex/AGENTS.md, NOTICE -- or when authoring a new skill or slash command file. Trigger on "update the README", "document this", "where should this fact live", "add a skill", "add a command", "the docs are stale", "docs drift", or any house-style question (emoji tags, dash style, commit-message format). Not for platform mechanics content itself (use claude-code-platform-reference), change gating and review process (use dotfiles-change-control), or public-repo/licensing posture decisions (use dotfiles-external-positioning).
