I have legacy endpoints that are no longer used in practice, there for historical reasons, intertwined with existing code etc. They might be marked obsolete, services implementing it are not - agent greps those, builds off of them - produces half legacy garbage.

Linters only handle trivial cases most of us already solved.

Yeah, we have a big struggle with this. We have lots of legacy code that doesn't follow our latest design patterns intermixed with new code. The LLM picks up bad habits depending on what it pulls in to context first. We have AGENTS.md configured with the right way, but old style still slips in. We obviously need to update the old code but on the other hand if it ain't broke why touch it.

I have the agent inject comments that mention that this particular code is legacy and must not be used as a reference, should not be cleaned up, etc. If you have a document that lists all of the reasons not to use or touch some code, the comments can simply be references to it.

    // LEGACY CODE, per docs/legacy_rules.md §14, §19

Thanks for the tip. I’ll try that out.
