Arcanea ecosystem self-description. Use when asked about the system map, where things live, canonical locations, how to add a skill/command/agent/hook, how to absorb a repo, or what's installed. Trigger phrases: arcanea meta, system map, where does X live, add a skill, absorb a repo, what's installed, ecosystem inventory.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Arcanea Meta The system describing itself with the same primitives it uses to build everything else. This skill is the load-bearing meta layer — the place to start when you don't know where something lives. ## Mental model Arcanea is **not one repo**. It is an ecosystem of ~90 repos at github.com/frankxai, plus four installed plugins, plus a hierarchy of skills/commands/agents/hooks at three scopes: ``` GLOBAL (~/.claude/) ← user-scope, every project sees this PROJECT (<repo>/.claude/) ← per-repo overrides + additions PLUGIN (~/.claude/plugins/cache/) ← marketplace-installed (read-only) ``` Most failures come from forgetting which scope a thing lives in. Default rule: **if it's reusable across repos, put it global. If it's Arcanea-specific, put it project. Never duplicate across both.** ## Canonical locations (verified 2026-04-15, see `references/canonical-locations.md` for full table) | Concern | Canonical | Why | |---|---|---| | Memory | `~/.claude/projects/C--Users-frank-Arcanea/memory/` | Auto-loaded via MEMORY.md every turn | | ACOS source | `~/agentic-creator-os/` | Has FRANK_DNA.md + memory.db (irreplaceable) | …

How to install
mdr add frankxai/claude-skills-library/arcanea-meta@sha256:39a9933cbc98017aThe line at the top of this page pins the label git:20260525.468c26e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
