+- External skill packs (the in-scope optional packs) are included in a full install and pruned by strict-sync when they leave scope; `--category external` narrows an install to external packs only. Large `source-pack` catalogs (`anthropic-cybersecurity-skills`, `rev-skills`) are deliberately **not** emitted (no `skill_roots`) and are served just-in-time by Grimoire instead.
 - Install manifests in `.agent-surface/<target>-manifest.json` track generated files and owned config entries. Full installs overwrite current generated assets, remove previously owned stale assets, and preserve unknown sibling config entries.
 
 ## First-party MCP services
 
 Built from `mcps/`, installed once, then auto-wired (non-destructive merge) into all 19 MCP-capable hosts across JSON/TOML/YAML config families — see [docs/reference/targets.md](docs/reference/targets.md):
 
 - **Synapse** — shared multi-agent memory + file-lock coordination.
-- **Grimoire** — read-only, just-in-time retrieval over large Agent-Skill packs (serves the 754-skill `anthropic-cybersecurity-skills` pack so the model searches for a skill instead of loading a 750-entry catalog).
+- **Grimoire** — read-only, just-in-time retrieval over large Agent-Skill packs (serves the 754-skill `anthropic-cybersecurity-skills` pack and the 121-skill `rev-skills` pack so the model searches instead of loading those catalogs at startup).
 
 `npm run install:mcps` builds both binaries and links them into `~/.local/bin` (Synapse also deploys its sidecar service); the agent-surface `install` step merges each server into every host's MCP config. Both steps are required — one wires the config, the other provides the binary it points at. (`npm run install:synapse` / `install:grimoire` install just one.) Details: [mcps/synapse/README.md](mcps/synapse/README.md), [mcps/grimoire/README.md](mcps/grimoire/README.md).
