+## System overview
+
+OpenCode plugins support two entry points:
+
+- `server` (loaded by the OpenCode server from `opencode.json`)
+- `tui` (loaded by the terminal UI from `tui.json`)
+
+A plugin can implement either entry point, or both in the same module.
+
+In short:
+
+- **v1 compatibility**: a default exported function is treated as a server plugin.
+- **v2 format**: export an object with `server` and/or `tui` keys.
+- **TUI plugin scope**: only plugins listed in `tui.json` are loaded for the TUI.

+- `serverUrl`: The server URL for the current OpenCode instance.
+

+
+### TUI plugins
+
+Plugins can also export a `{ server, tui }` object. The server loader executes `server` (same as a normal plugin function). The TUI loader executes `tui` **only** when a TUI is running.
+
+To load a TUI plugin, add it to `tui.json`:
+
+```json title="tui.json"
+{
+  "plugin": ["my-tui-plugin"]
+}
+```

+```ts title=".opencode/plugins/example.ts"

+- `event`: an event bus for server events
+- `renderer`: the active OpenTUI renderer instance
+- `url`: server URL
