+While the LLVM project has a liberal policy on AI tool use, contributors are
+considered responsible for their contributions. We encourage contributors to
+review all generated code before sending it for review to verify its
+correctness and to understand it so that they can answer questions during code
+review. Reviewing and maintaining generated code that the original contributor
+does not understand is not a good use of limited project resources.
