feat: Complete Phase 1 & 2 - Schematic workflow fix and JLCPCB integration
Phase 1: Schematic Workflow Fix (Issue #26) - Fixed broken schematic workflow using template-based symbol cloning - Updated create_project to generate both PCB and schematic files - Rewrote add_schematic_component to use kicad-skip clone() API - Added template schematics with cloneable R, C, LED symbols - All schematic tests now passing Phase 2: JLCPCB Integration Complete - Integrated JLCSearch public API (no authentication required) - Access to ~100k JLCPCB parts with real-time stock and pricing - Implemented parametric search for resistors, capacitors, components - Added package-to-footprint mapping for KiCad integration - Cost optimization with Basic vs Extended library classification - Alternative part suggestions with price comparison New Components: - python/commands/jlcsearch.py - JLCSearch API client - python/templates/ - Template schematics for symbol cloning - docs/JLCPCB_INTEGRATION.md - Comprehensive API documentation - docs/SCHEMATIC_WORKFLOW_FIX.md - Phase 1 technical details - CHANGELOG.md - Consolidated unified changelog - PHASE_2_COMPLETE.md - Phase 2 implementation summary MCP Tools Available: - download_jlcpcb_database - Download full parts catalog - search_jlcpcb_parts - Parametric search with filters - get_jlcpcb_part - Part details + footprint suggestions - get_jlcpcb_database_stats - Database statistics - suggest_jlcpcb_alternatives - Find similar/cheaper parts Technical Improvements: - SQLite database with FTS5 full-text search - HMAC-SHA256 authentication support (official JLCPCB API) - Improved .gitignore to exclude credentials and databases - Template-based schematic creation workflow Testing: - All integration tests passing - Database operations validated - Live API connectivity confirmed - Schematic workflow end-to-end verified Credits: - JLCSearch API: @tscircuit - Local JLCPCB search: @l3wi Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
