 ## Architecture
 - **DualAgentOrchestrator**: Main entry point, coordinates Driver and Guardian agents
-- **DriverAgent**: Reasons about tasks, plans steps, proposes tool calls
+- **DriverAgent**: Reasons about tasks, plans steps, proposes tool calls (supports both XML and native tool calling)
 - **GuardianAgent**: Evaluates tool calls against configured policies
 - **BaseToolWrapper**: Base class for creating custom tools
 - **plugins.ts**: Imports and re-exports smartai and other dependencies
 
-## Standard Tools
+## Standard Tools (via registerStandardTools)
 1. **FilesystemTool** - File operations with scoping and exclusion patterns
 2. **HttpTool** - HTTP requests
 3. **ShellTool** - Secure shell commands (no injection possible)
 4. **BrowserTool** - Web page interaction via Puppeteer
 5. **DenoTool** - Sandboxed TypeScript/JavaScript execution
-6. **JsonValidatorTool** - JSON validation and formatting

 ## Key Features
 - Token streaming support (`onToken` callback)

 - Scoped filesystem with exclusion patterns
 - Result truncation with configurable limits
 - History windowing to manage token usage
+- **Native tool calling mode** (`useNativeToolCalling: true`) for providers like Ollama
+
+## Native Tool Calling
+When `useNativeToolCalling` is enabled:
+- Uses provider's built-in tool calling API instead of XML parsing
+- Tool names become `toolName_actionName` (e.g., `json_validate`)
+- Streaming includes `[THINKING]` and `[OUTPUT]` markers
+- More efficient for models that support it
 
 ## Key Dependencies
 - `@push.rocks/smartai`: Multi-provider AI interface
