# Week 1 - Session 1 Summary
|
|
|
|
**Date:** October 25, 2025
|
|
**Status:** ✅ **EXCELLENT PROGRESS**
|
|
|
|
---
|
|
|
|
## 🎯 Mission
|
|
|
|
Resurrect the KiCAD MCP Server and transform it from a Windows-only "KiCAD automation wrapper" into a **true AI-assisted PCB design companion** for hobbyist users (novice to intermediate).
|
|
|
|
**Strategic Focus:**
|
|
|
|
- Linux-first platform support
|
|
- JLCPCB & Digikey integration
|
|
- End-to-end PCB design workflow
|
|
- Migrate to KiCAD IPC API (future-proof)
|
|
|
|
---
|
|
|
|
## ✅ What We Accomplished Today
|
|
|
|
### 1. **Complete Project Analysis** 📊
|
|
|
|
Created comprehensive documentation:
|
|
|
|
- ✅ Full codebase exploration (6 tool categories, 9 Python command modules)
|
|
- ✅ Identified critical issues (deprecated SWIG API, Windows-only paths)
|
|
- ✅ Researched KiCAD IPC API, JLCPCB API, Digikey API
|
|
- ✅ Researched MCP best practices
|
|
|
|
**Key Findings:**
|
|
|
|
- SWIG Python bindings are DEPRECATED (will be removed in KiCAD 10.0)
|
|
- Current architecture works but is Windows-centric
|
|
- Missing core AI-assisted features (part selection, BOM management)
|
|
|
|

|
|
|
|
### 2. **12-Week Rebuild Plan Created** 🗺️

|
|
- Digikey integration (parametric search)
|
|

|
|
|
|
#### **Phase 3: Novice-Friendly Workflows (Weeks 9-11)**

|
|
|
|
---
|
|
|
|
## 💡 Key Decisions Made
|
|
|
|
### 1. **IPC API Migration: Proceed Immediately** ✅
|
|
|
|
- SWIG is deprecated, will be removed in KiCAD 10.0
|
|
- IPC API is stable, officially supported
|
|
- Better performance and cross-language support
|
|
- Decision: Migrate in Week 2-3
|
|
|
|
### 2. **Linux-First Approach** ✅
|
|
|
|
- Hobbyists often use Linux
|
|
- Better for open-source development
|
|
- Easier CI/CD with GitHub Actions
|
|
- Decision: Linux is primary development platform
|
|
|
|
### 3. **JLCPCB Integration Priority** ✅
|
|
|
|
- Hobbyists love JLCPCB for cheap assembly
|
|
- "Basic parts" filter is critical
|
|
- Better stock than Digikey for hobbyists
|
|
- Decision: JLCPCB before Digikey
|
|
|
|
### 4. **Pytest over unittest** ✅
|
|
|
|
- More Pythonic
|
|
- Better fixtures and parametrization
|
|
- Industry standard
|
|
- Decision: Use pytest for all tests
|
|
|

|
## 🎓 Lessons Learned
|
|
|
|
### Technical Insights
|
|
|
|
1. **XDG Base Directory Spec** - Linux has clear standards for config/cache/data
|
|
2. **pathlib > os.path** - More readable, cross-platform by default
|
|
3. **Platform detection** - Check environment variables before hardcoding paths
|
|
4. **Type hints** - Make code self-documenting and catch bugs early
|
|
|
|
### Process Insights
|
|
|
|
1. **Audit first, code second** - Understanding the problem space saves time
|
|
2. **Infrastructure before features** - CI/CD and testing pay dividends
|
|
3. **Documentation is code** - Good docs prevent future confusion
|
|
4. **Cross-platform from day 1** - Retrofitting is painful
|
|

|
|
|
|
### Dependencies to Research

|
|
- [ ] kicad-python 0.5.0 compatibility
|
|
|
|
### Questions to Answer
|
|
|
|
- [ ] How to handle KiCAD running vs not running (IPC requirement)?
|
|
- [ ] Should we support both SWIG and IPC during migration?
|
|
- [ ] BOM format standardization?
