**Comprehensive Coverage**: Tools handle common extraction scenarios - **Backward Compatibility**: All existing tools continue to work unchanged ## 📊 Technical Implementation ### Architecture Changes All new functionality follows the established three-layer architecture: 1. **Daemon Layer** (`daemon/daemon.go`): - Lines 620-703: Command handlers for new extraction commands - Lines 2542-2937: Implementation methods with timeout handling 2. **Client Layer** (`client/client.go`): - Lines 824-857: New data structures for structured responses - Lines 989-1282: Client methods with parameter validation 3. **MCP Layer** (`mcp/main.go`): - Lines 933-1199: MCP tool definitions with comprehensive schemas ### Key Features Implemented - **Batch Processing**: Multiple selectors processed in single calls - **Advanced Filtering**: Regex patterns for href and text filtering - **Structured Output**: Consistent JSON formatting across all tools - **Error Resilience**: Graceful handling of missing or invalid elements - **Timeout Management**: Configurable timeouts for all operations - **Pattern Matching**: Built-in regex support for text extraction ## 📚 Documentation Updates ### Comprehensive Documentation - **README.md**: Updated with Phase 2 tools and examples -
