+## AI Contribution Guidelines
+
+PRs prepared using AI tools must follow these requirements:
+
+1. You must review all AI-generated code before uploading it for review, and before requesting
+   re-review of any updates to the uploaded change.
+   * You are responsible for ensuring that code you submit meets coding standards.
+   * Unmodified AI output generally does _not_ meet those standards.
+2. You must ensure that uploaded code compiles and passes at least the tests you have yourself
+   added as part of the change.
+3. You must understand and be able to discuss the code you are uploading for review.
+   * Non-trivial changes require discussion and iteration during review. If you do not understand the
+     code, you cannot meaningfully respond to review feedback.
+   * In our experience, simply feeding review feedback into an AI agent and uncritically reposting
+     its output will not lead to a constructive review.
+4. You must verify the accuracy of any AI-generated text you include in the change description or
+   review discussion comments.
+   * If an AI provides you incorrect information, it is just hallucinating; if you choose to paste
+     that text into GitHub, you are misrepresenting your change to your reviewer.
+   * In particular, do not tell a reviewer that you have addressed their feedback just because
+     AI output says so. It is your responsibility to make sure that review feedback has actually
+     been addressed.
