From Design doc to code: the Groundhog AI coding assistant (and new Cursor meta)

March 5, 2025

Today, alongside with teaching you the technique I’m announcing the start of a new open-source (yes, I’m doing this as pure OSS and not my usual proprietary licensing) AI headless agentic coding agent called “groundhog”.

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!).

We’ve cited Geoff Huntley a couple of times in recent weeks and today he’s announced a new AI headless agentic coding agent called “groundhog”.

I’m still a little skeptical (this seems to put me inane minority right now) about how ‘agentic’ agents might be in the coming months (my experience with all manner of tools for code generation is they tend to drift over time and need to be corrected and nudged back toward the right focus, but the entire field of AI Engineering seems to think otherwise so…)

I’ll certainly be giving this a look at.
