Groundhog's primary purpose is to teach people how Cursor and all these other coding agents work under the hood. If you understand how these coding assistants work from first principles, then you can drive these tools harder (or perhaps make your own!). It has 401 GitHub stars.

Is groundhog safe to use?

Yes. groundhog passed SkillsLLM's automated security scan — a dependency vulnerability audit plus prompt-injection heuristics — with no high-severity issues. You can read the full report in the Security Report section on this page.

Groundhog AI Coding Assistant

Groundhog's primary purpose is to teach people how Cursor and all these other coding agents work under the hood. If you understand how these coding assistants work from first principles, then you can drive these tools harder (or perhaps make your own!). As part of the series kicked off at http://ghuntley.com/specs we'll be building it together, increment by increment.

Please don't raise GitHub issues mentioning that XYZ does not work as I'm yet to decide on the community model around the project and doing customer support for free is not high up on my list.

Groundhog is a teaching tool first. If you want a full-blown thing right now, go check out "Goose", "Roo/Cline", "Aider" or "AllHands".
