Notes from the copper.
What the agent is, the problem it exists to solve, and the rules it runs under. Every claim here is demonstrable in the repo today.
copperhead: Cursor for circuit boards
copperhead is an AI agent that designs, documents, and validates real PCBs from a prompt, working on your existing KiCad repository. Built and proven on a shipping open source board.
ReadFrequently asked questions
What it costs, what it refuses to do, whether it replaces an engineer, and what happens to your design files.
ReadSpec-gated in, verification-gated out
The two invariants that make an agent safe to point at real design files, and the six-step loop that runs between them.
ReadDrift is a build failure
Hardware design holds dozens of cross-cutting constraints at once, and every change touches artifacts that quietly fall out of sync. That drift is what ships to fabrication.
