The most effective argument I have for getting other developers to comment their code is "The agent will read it and it will give better suggestions".
Truly perverse, but it works.
I agree with you... but the reality is that there's a wide contingent of people that are not capable of understanding "people don't know the same things as me". So they need some other reason.
It's made my project documentation so much better. If I write out really good acceptance criteria, 9 times out of 10 I can point Claude at the ticket and get a workable (if unpolished) solution with little to no supervision.
1) an AI agent is less likely to notice than even a junior is when the docs are out of date from the code
2) AI boosters are always talking about using language models to understand code, but apparently they need the code explained inline? are we AGI yet?
3) I frequently hear how great AI is at writing comments! But it needs comments to better understand the code? So I guess to enable agentic coding you also have to review all the agents' comments in addition to the code in order to prevent drift
Well... Yah. For the record I'm saying this to trick humans into making better comments for humans. It is very difficult to convince people to do this otherwise, in my experience.
buuut...
I will also mention that these agent files are typically generated by agents. And they're pretty good at it. I've previously used agents to dissect unfamiliar code bases in unfamiliar languages and it has worked spectacularly well. Far far FAR better than I could have done on my own.
I have also been shocked at how dumb they can be. They are uselessly stupid at their worst, but brilliant at their best.
I don’t think they serve the same purpose. Most of the instructions I have for an agent won’t apply to a human. It’s mostly around the the requirements to bootstrap the project vs what I’d ask for a human to accept their pull request.
The content of the AGENTS.md is the same as what humans are looking for when contributing to a project.
