-## AI Assistance Notice
+## AI Assistance Best Practices
+
+AI-assisted coding has changed the nature of contributions. AI tools can now generate large volumes of (typically) low-quality code quickly, increasing the burden on reviewers and reducing opportunities for meaningful feedback. As a result, we urge contributors to disclose _how_ they used AI assistance and follow the best practices below.
+
+Contributors could attest to:
+
+- "I've reviewed and understood all code before submitting."
+- "I've tested the changes and ensured they address only the issue at hand."
+- "I've asked an AI system to review this code."
+- "I've refined any AI-generated output to meet our standards."
+- "I've looked at generated tests and ensured they are meaningful. e.g., they avoid using fragile mocks."
 
 > [!IMPORTANT]
->
-> If you are using **any kind of AI assistance** to contribute to Llama Stack,
-> it must be disclosed in the pull request.
-
-If you are using any kind of AI assistance while contributing to Llama Stack,
-**this must be disclosed in the pull request**, along with the extent to
-which AI assistance was used (e.g. docs only vs. code generation).
-If PR responses are being generated by an AI, disclose that as well.
-
-An example disclosure:
-
-> This PR was written primarily by Claude Code.
-
-Or a more detailed disclosure:
-
-> I consulted ChatGPT to understand the codebase but the solution
-> was fully authored manually by myself.
-
-Failure to disclose this is first and foremost rude to the human operators
-on the other end of the pull request, but it also makes it difficult to
-determine how much scrutiny to apply to the contribution.
-
-Please be respectful to maintainers and disclose AI assistance.
+> We would like to move the emphasis from whether AI was used to _how_ it was used and what human oversight was applied.
