+## Automated Tools
+
+The use of AI tooling for assisted development work is accepted and encouraged
+in this repository, but due to the volume of submissions we ask that you observe
+the following rules:
+
+- All issue and pull request submissions to this repository that are sourced by
+  AI must first be reviewed by a human before submitting to the repository.
+  Items reviewed in this way must include a statement like "generated by AI
+  tools, and reviewed by <person>"
+- Please ensure that your submissions are actually improvements. While we are
+  grateful for any proposed fixes, even if they are very small, behavior that
+  looks like creating nuisance PRs or artificially inflating submission counts
+  is not acceptable.
+- We may close issues or pull requests, or limit your ability to interact with
+  this repository, for behavior that in our estimation violates these rules or
+  any of the other rules in this repository's
