Show HN: Boffin – Staff-engineer layer for AI coding agents

A new Hacker News launch called Boffin is pitching itself as the adult in the room for AI coding tools: when a bot is supposed to make a tiny code fix, Boffin tries to stop it from barging in and remodeling the whole house. The creator says it feeds the AI only the rules that matter for the specific file being edited, then forces it to check its work. The sales pitch is simple even for non-coders: less cowboy behavior, more staying in your lane. And yes, the post came with receipts, including a DuckDB test where a very small change passed more than 2,000 checks.

But the real show was in the comments, where the crowd split into curious collaborators, polite skeptics, and certified roast artists. One commenter basically said, “we’re building similar stuff, let’s talk,” which gives this whole space a very “everyone is inventing the same seatbelt for AI at once” energy. Another wasn’t fully sold, arguing that much of this sounds like fancy packaging around instructions developers already write in files like CONTRIBUTING guides. In other words: is this a breakthrough, or just better organized nagging?

And then came the killer joke. User jchook dropped the line of the thread: “Can an AI slop plugin effectively make AI less sloppy?” That snark perfectly captured the mood. People clearly like the problem Boffin is trying to solve, because runaway AI edits are a real pain. But they’re also side-eyeing whether one more layer, one more plugin, and one more set of rules can truly tame the chaos. On Hacker News, that’s basically a standing ovation with a raised eyebrow.
