CAO plugins are observer-only extensions that react to server-side events (session/terminal lifecycle, message delivery) inside cao-server. They run in-process and are notified after each event occurs. For the full reference — installation, events, configuration, and troubleshooting — see docs/plugins.md.
| Example | Description |
|---|---|
| cao-discord | Forwards inter-agent messages to a Discord channel via webhook, rendering your CAO workflow as a live group chat in Discord. |
To scaffold a new plugin from scratch, use the cao-plugin skill (skills/cao-plugin/SKILL.md). For the plugin API and hook contract, see docs/plugins.md § Authoring a plugin.
