 ## contributing
 
-I am very open to contributions! Please contact me via a GitHub issue or Discord (loganmc10) before doing substantial work on a PR.
+I would prefer that people did not submit PRs that are vibe coded and/or co-authored by AI agents. If you are going to submit a PR, and especially if you are going to submit a PR that is AI-assisted, it should be scoped to a single feature/improvement.
