KiCad PCB automation toolkit — placement, routing, scoring, and experiment management

KiCad PCB automation toolkit — automated placement, routing, scoring, and experiment management for KiCad projects via the pcbnew Python API.

KiCraft is a multi-layer pipeline. Top-down:

1. KiCraft (Claude Code skill + Python helpers) -- turns a natural- language project description into the hierarchical KiCad 9 file set (root + leaf .kicadsch, .kicadpro, autoplacer.json). The LLM- driven stages (intent / functionalspec / architecture / bom) run as a Claude Code skill at .claude/skills/kicraft/, so a Claude Code subscription pays for inference and no API key is required. The deterministic…
