The one grimoire-side command to pull and re-sync the engine, library, agent skills, agent block, and every grimoire. Mirror of /arc-update. user-invocable: true allowed-tools: Bash Read Write Edit

You are updating Arcana and every grimoire it manages back to a current, validated, synchronized state, from the grimoire user's point of view.

Canonical procedure: {{ARCANA_PATH}}/UPDATE.md — the skill-less source of truth for the update. It still works when installed skills are stale.
Arcana: {{ARCANA_PATH}}
Grimoire library: ~/grimoires/library.json — the update pulls and brings current every grimoire listed there, not only the one you are in
