+### Assisted-by:
+
+When AI tools contribute to Xen development, proper attribution
+helps track the evolving role of AI in the development process.
+Contributions should include an `Assisted-by:` tag in the
+following format:
+
+    Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]
+
+Where:
+
+* `AGENT_NAME` is the name of the AI tool or framework
+* `MODEL_VERSION` is the specific model version used
+* `[TOOL1] [TOOL2]` are optional specialized analysis tools used
