kicad-agent-toolkit

This command-line toolkit lets an AI agent, or a patient human, take a KiCad 10 board from schematic to fabrication outputs without the GUI and without trusting its own claims. Routing only moves forward: Freerouting rounds with per-net acceptance, a maze router and a GPU router for the last breaks, and diagnostics that say why a connection has no path and which nets form the wall. Board-to-schematic sync adds, removes, and re-assigns footprints and pad nets from the netlist without the F8 key.

A verification gate covers what ERC, DRC, and parity miss: decoupling path length, pins without a net, IR drop on real copper, power-up sequencing, RF reference continuity, support-part asymmetry between identical ICs, and component ratings against rail voltages. Tools that edit a board print a plan by default, write only with an apply flag, and leave the verdict to kicad-cli pcb drc. The toolkit grew out of a dense 6-layer mixed-signal board with about 370 footprints and 1,700 pads that an agent took to a DRC-clean fabrication release, with lessons written up in the docs.
