 ## Module-Level Commands
 
-Currently, no additional modules are exposed via D-Bus beyond the base service commands.
+Module-level commands are available and can be discovered via `ListModules`. Two key additions are:
 
-**Planned modules** (to be implemented):
-- `SpeechAndVerbosityManager` - Speech settings control (muting, verbosity, punctuation, etc.)
-- `TypingEchoManager` - Typing echo settings (character/word/sentence echo)
-- `DefaultScript` - Core Cthulhu commands
-- Additional navigation and presenter modules
+### PluginSystemManager
+
+Session-only plugin control (does not persist preferences):
+
+- `ListPlugins`
+- `ListActivePlugins`
+- `IsPluginActive` (parameterized)
+- `SetPluginActive` (parameterized)
+- `RescanPlugins`
+
+### Plugin Modules
+
+Plugins that expose D-Bus decorators are automatically registered as modules using the naming
+convention `Plugin_<ModuleName>` (e.g., `Plugin_GameMode`, `Plugin_WindowTitleReader`).
 
 See [README-REMOTE-CONTROLLER.md](README-REMOTE-CONTROLLER.md) for comprehensive D-Bus API documentation and usage examples.
