 ### Using AI
 
-Generative AI is fast becoming a first-party feature in most development environments, including GitHub itself. If you use Generative AI to write the vast majority of your submission (e.g., agent-based or vibe coding) then you **must document your use of AI** in your pull request. Please include the service you used and/or model that generated the code. All code submissions go through a rigourous review process regardless of the development workflow used.
