 Plugins can communicate over a plugin-only message bus through `api.messageBus`. It sends `plugin-message-bus` data-channel events that are ignored by the normal chat message reducers/effects, can target a peer or broadcast to connected users, and can include a bounded latest-message snapshot filtered by channel, timestamp, and deletion state.
 
+Plugins can inspect the current interaction context through `api.context.getCurrent()`. Composer action callbacks also receive this context directly, including the local user, current chat server, active text channel, and the user's current voice channel when connected. Plugins with message access can call `api.messages.setTyping(true | false, channelId?)` and can observe peer typing state with `api.messages.subscribeTyping(handler)`, where typing events include the user, server, text channel, and voice channel when those records are available locally.
+
 Desktop plugin preferences that belong to the local user, including capability grants, disabled plugin ids, and previously activated plugin ids, are persisted through Electron's local database meta table with renderer localStorage as the browser fallback.
 
 Runtime activation is explicit. `PluginHostService.activateReadyPlugins()` imports browser-safe plugin entrypoints from URL-resolvable manifests, passes a frozen `TojuClientPluginApi`, runs `activate`, then runs `ready` after the load-order pass. Successfully activated plugin ids are remembered locally, and store-installed plugins are reactivated for the active server when their persisted manifests load again. `deactivate` runs during unload/reload, disposables are cleaned in reverse order, and UI contributions are removed by plugin id.
