Description
Copperhead is a collaborative open-source AI platform aimed at aiding hardware teams in the design, validation, and production of circuit boards. By simply detailing a modification or submitting a product brief, users can prompt the agent to make precise edits to actual KiCad files, revise any related documentation, and perform KiCad's built-in checks until all pass successfully. The comprehensive workflow encompasses various stages, including specification, architecture, component selection, schematic design, layout, output generation, firmware creation, and development strategy, ensuring that each phase produces a tangible artifact on disk before progressing. Validation gates check for budget adherence, logical subsystem analysis, datasheet-supported component numbers, ERC-compliant schematics, DRC-compliant layouts, generated Gerber files, firmware source code, and comprehensive bring-up plans. Additionally, Copperhead is equipped to handle modifications for existing boards: users can direct it to a KiCad repository, start the project, and request specific changes. The edits made are targeted adjustments to KiCad source files, ensuring that changes are minimal and easily reviewable while leaving other sections intact. This approach allows for a streamlined revision process that minimizes disruption to the overall project.
Description
Keelen operates as an independent coding loop designed to transform open-ended requests into a structured and prioritized roadmap. It then subdivides items from this roadmap into development-ready tasks complete with acceptance criteria, executing each task in a secure, isolated VM environment using your designated credentials from Claude, Codex, GLM, or Kimi, ultimately producing a merged pull request or retaining it for review based on your settings.
Every modification undergoes a series of five verification checkpoints prior to merging: an initial red-first test proof, a separate adversarial review of the changes by a model that lacks context from the preceding run, the execution of the project’s own test suite on a fresh checkout, a CI-green mandate, and a designated review period before automated merging is allowed. Importantly, the process is structured to ensure that no checks are compromised to achieve a green status.
Each iteration is conducted in a temporary, non-root VM that is eliminated at the conclusion of the run, featuring a deny-by-default policy on network access. Additionally, the GitHub tokens utilized for each run are limited in scope to a single repository.
It's essential to note that Keelen does not function as an IDE copilot nor as a chat interface; its capabilities are distinctly designed to automate and streamline the coding workflow.
