This commit completes the canUseTool permission functionality implementation in the Python SDK to match the TypeScript SDK behavior: ## Key Changes: 1. **Transport Layer Enhancement** (`subprocess_cli.py`): - Added `--can-use-tool` CLI flag when canUseTool callback is provided - Ensures the CLI process knows to enable permission callback mode 2. **Example Implementation** (`can_use_tool_example.py`): - Comprehensive example showing how to use canUseTool callbacks - Demonstrates security policies, input modification, and denial patterns - Shows integration with ClaudeSDKClient in streaming mode ## Features Already Implemented: - **Type Definitions**: CanUseTool, PermissionResult*, ToolPermissionContext in `types.py` - **Client Integration**: Full canUseTool support in ClaudeSDKClient with proper validation - **Query Support**: Both query() function and ClaudeSDKClient handle canUseTool callbacks - **Control Protocol**: Complete bidirectional permission request/response handling - **Input Validation**: Ensures streaming mode is required, mutual exclusion with permission_prompt_tool_name - **Comprehensive Tests**: Full test coverage in test_tool_callbacks.py The implementation follows the TypeScript SDK's architecture exactly, providing: - Tool permission interception before execution - Input modification capabilities - Permission updates and suggestions - Proper error handling and validation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
