cavi-ai/plugins is CAVI's host-neutral discovery catalog for installable agent extensions. Plugin source stays in each plugin's own repository; this repository publishes one canonical catalog and validated host projections.
| Plugin | Claude | Codex | Agy | OpenCode | OpenClaw | Hermes | AgentSkills |
|---|---|---|---|---|---|---|---|
mlx-agent — discover, verify, and wire local MLX models |

The machine-readable source of truth is catalog.json. Claude and Codex consume native marketplace projections. Agy, OpenCode, OpenClaw, and Hermes use the discovery records under providers/, which link to each source repository's tested installer; those files do not claim a native marketplace protocol. Portable AgentSkills packages remain available from each plugin repository.
Add the marketplace, then install a plugin:
/plugin marketplace add cavi-ai/plugins
/plugin install mlx-agent@cavi-ai
/plugin install obsidian-agent@cavi-ai
/plugin install loop-killer@cavi-ai
Add the marketplace, then install either plugin:
codex plugin marketplace add cavi-ai/plugins
codex plugin add mlx-agent@cavi-ai
codex plugin add obsidian-agent@cavi-aiThe Codex projection at .agents/plugins/marketplace.json uses Codex's documented marketplace-local source layout. packages/codex/ contains minimal, self-contained projections copied from exact upstream commits. Each package includes provenance and a deterministic tree hash; catalog validation rejects local drift.
These package projections are distribution artifacts, not independent workflow sources. Refresh one only from a reviewed upstream commit, update its provenance.json, and run the full catalog gate. Product development remains in the linked plugin repository.
Agy discovery metadata is in providers/agy/catalog.json. Each entry records the source repository's native installation command:
git clone https://github.com/cavi-ai/mlx-agent.git
agy plugin install ./mlx-agent/providers/agyThe discovery catalog itself does not install anything. obsidian-agent does not ship an Agy plugin.
OpenCode discovery metadata is in providers/opencode/catalog.json. Both source repositories provide preview-first installers:
git clone https://github.com/cavi-ai/mlx-agent.git
python3 mlx-agent/scripts/mlx-agent install opencode --scope user --dry-run --json
git clone https://github.com/cavi-ai/obsidian-agent.git
node obsidian-agent/scripts/install.mjs --host opencode --scope user --dry-runReview the destination paths and use the exact preview hash when confirming.
OpenClaw and Hermes discovery metadata is in providers/openclaw/catalog.json and providers/hermes/catalog.json. The mlx-agent installer places its skills in $OPENCLAW_STATE_DIR/skills or $HERMES_HOME/skills:
git clone https://github.com/cavi-ai/mlx-agent.git
python3 mlx-agent/scripts/mlx-agent install openclaw --scope user --dry-run --json
python3 mlx-agent/scripts/mlx-agent install hermes --scope user --dry-run --jsonReview the destination paths and use the exact preview hash when confirming. obsidian-agent does not ship an OpenClaw or Hermes adapter.
Both plugins publish portable skills under their AgentSkills adapter. Follow the selected repository's project- or user-scope installation instructions; the catalog does not copy or fork skill content.
Node.js 22 or newer is sufficient:
node --test
node scripts/validate-catalog.mjsValidation rejects identity drift, unknown hosts, packages for undeclared hosts, duplicate entries, non-plugin products, and projections that disagree with the canonical host list, repository, or package path.
