In their own words
Code contributions
You must disclose whether AI has been used to assist in the development of your pull request.
You must understand and be able to explain the code you submit as well as the existing related code.
Code generated by AI may infringe on copyright and it is the submitter’s responsibility to not infringe.
The use of an AI agent that writes code and then submits a pull request autonomously is not permitted.
Issues & bug reports
In explaining your contribution, do not use AI to automatically generate comments, pull request descriptions, or issue descriptions.
AI-written text
When interacting with developers (forums, discussions, issues, pull requests, etc.) do not use AI to speak for you, except for translation or grammar editing.
