About

Copperhead is an open source AI engineering platform that helps hardware teams design, verify, and ship circuit boards. You describe a change or provide a product brief, and the agent edits real KiCad files, updates the documents that reference them, and runs KiCad’s own checks until they pass. Its end-to-end workflow moves through specification, architecture, parts selection, schematic, layout, outputs, firmware, and development planning, with each stage required to leave a real artifact on disk before the next begins. Gates verify budgets, subsystem reasoning, datasheet-backed part numbers, ERC-clean schematics, DRC-clean layouts, generated Gerbers, firmware sources, and written bring-up plans. Copperhead is also designed for existing boards: point it at a KiCad repository, initialize the project, and ask for changes. Edits are surgical changes to KiCad source files, keeping diffs small and reviewable while untouched portions remain unchanged.

About

Keelen is an autonomous coding loop. It turns free-form requests into a prioritized roadmap, breaks roadmap items into dev-ready tasks with acceptance criteria, implements each task in an isolated single-use VM using your own Claude, Codex, GLM, or Kimi credentials, and ships the result as a merged pull request, or holds it for review if that is how you configure it. Every change passes five verification gates before merge: a red-first test proof, an independent adversarial review of the diff by a model that shares no context with the run that wrote it, the project's own test suite on a clean checkout, a CI-green requirement, and a review window before gated auto-merge. The loop may never weaken a check to reach green. Each iteration runs in a single-use, non-root VM that is destroyed when the run ends, with deny-by-default network egress. Per-run GitHub tokens are scoped to one repository. Keelen is not an IDE copilot and not a chat agent.
