It just prevents hallucinations and coerces the AI to use existing files and APIs instead of inventing them. It also has gold-standard tests and APIs as examples.
Before the agents file, it was just chaos of hallucinations and having to correct it all the time with the same things.
The good: It shows on one kind of benchmark, some flavors of agentically-generated docs don't help on that task. So naively generating these, for one kind of task, doesn't work. Thank you, useful to know!
The bad: Some people assume this means in general these don't work, or automation can't generate useful ones.
The truth: Instruction files help measurably, and just a bit of engineering enables you to guarantee high scores for the typical cases. As soon as you have an objective function, you can flip it into an eval, and set an AI coder to editing these files until they work.
Ex: We recently released https://github.com/graphistry/graphistry-skills for more easily using graphistry via AI coding, and by having our authoring AI loop a bit with our evals, we jumped the scores from 30-50% success rate to 90%+. As we encounter more scenarios (and mine them from our chats etc), it's pretty straight forward to flip them into evals and ask Claude/Codex to loop until those work well too.
We do these kind of eval-driven AI coding loops all the time , and IMO how to engineer these should be the message, not that they don't work on average. Deeper example near the middle/end of the talk here: https://media.ccc.de/v/39c3-breaking-bots-cheating-at-blue-t...
I suspect AGENTS.md files will prove to be a short-lived relic of an era when we had to treat coding agents like junior devs, who often need explicit instructions and guardrails about testing, architecture, repo structure, etc. But when agents have the equivalent (or better) judgement ability as a senior engineer, they can make their own calls about these aspects, and trying to "program" their behaviour via an AGENTS…
The research mostly points to LLM-generated context lowering performance. Human-generated context improves performance, but any kind of AGENTS.md file increases token use, for what they say is "fake thinking." More research is needed.
I’d say that it needs to be maintained and reviewed by a human, but it’s perfectly fine to let an LLM generate it.
I have a legacy codebase of around 300k lines spread across 1.5k files, and have had amazing success with the agents.md file. It just prevents hallucinations and coerces the AI to use existing files and APIs instead of inventing them. It also has gold-standard tests and APIs as examples.

You might have better luck with more focused task-specific instructions if you can be bothered to write them.

Eh, even for a senior engineer, dropping into a new codebase is greatly helped by an orientation from someone who works on the code. What's where, common gotchas, which tests really matter, and so on. The agents file serves a similar role.
Earlier quoted context omitted.

I do write them, but without the agents file, I would end up pasting the same contents each time I start work on something, which seems like a waste of time.
