 Thank you for wanting to contribute to `nmrs`!
 
 I'm fairly accepting to all PR's, only with a couple caveats: 
-- Do not submit low-effort or autogenerated code. If you absolutely must, please disclose _how_ you used AI otherwise I will close the PR.
+- Do not submit low-effort or purely LLM generated code. If you absolutely must, please disclose _how_ you used AI otherwise I will close the PR.
 - Please try to (when possible) contribute to an [issue](https://github.com/cachebag/nmrs/issues). This is not a hard ask, I'll still consider your contribution if it makes sense.
