You’ll likely have the same issue relying on CLAUDE.md instructions to test/lint/etc, mine get ignored constantly to the point of uselessness.

I’m trying to redesign my setup to use hooks now instead because poor adherence to rules files across all the agentic CLIs is exhausting to workaround.

(and no, Opus 4.5 didn’t magically solve this problem to preemptively respond to that reply)

What do your rules files look like?

I wonder if some people are putting in too much into their markdown files of what NOT to do.

I hate people saying the llms are just better auto-correct, but in some ways they're right. I think putting in too much "don't do this" is leading the llm down the path to do "this" because you mentioned it at all. The LLM is probabilistically generating it's response based on what you've said and what's in the markdown files, the fact you put some of that stuff in there at all probably increases the probability those things will show up.
