Ask HN: Do you still spend time maintaining Claude.md / AGENTS.md files?

3•david_d8912•48m ago
For people using coding agents regularly: do you still invest time in repo-level instruction files like CLAUDE.md, AGENTS.md, etc.?

It's not a surprise that you don't expect the rules there to be followed even with less than 100 lines of changes. Yet still see folks like Karpathy post rules around with hundreds of stars.

Tell me if you're still spending the effort of trying claude.md, and are they effective, what're you writing in it.

AGENTS.md is extremely important - it's probably the highest leverage thing you can give your agent. It's injected into every turn, and the agents are trained to follow instructions. If anything, I think people are under-investing into AGENTS.md and going purely based on vibes.

For example, if I write a bad AGENTS.md for a repo with 100 engineers actively working in it, then every agent for every engineer gets worse, without anyone really noticing.

I think we should move towards data-based tuning of AGENTS.md, testing out changes, gathering data, and then making a decision on whether or not to ship it.
