Implementation Reference
- kicad_mcp/tools/pattern_tools.py:152-196 (handler)The core handler function for the 'analyze_project_circuit_patterns' tool. It validates the project path, retrieves the schematic file using get_project_files, and delegates pattern analysis to the identify_circuit_patterns function, augmenting the result with project path.
