Doc Revision: Contributing

[markstur]

I'm adding this on behalf of some doc feedback... The notes are a bit raw... The gist is we should have a policy about AI use in PRs (whatever it might be) and make that visible in our contributors docs, repos, maybe PR template.

Summary of Requested Changes:

AI Agent contributions… this is a new problem. We need popular OSS repos to make a maintainer supported statement regarding use of agents.
example scenario matplotlib/matplotlib#31132
happens a lot now.. agents pushing PRs/commits..
this and the obvious other issue of devs generating code from claude/gemini/… and not attributing

Example: https://github.com/ggml-org/llama.cpp/blob/master/AGENTS.md#guidelines-for-contributors-using-ai

I’d start to describe a loose restriction policy, but leave it blank and refer to an issue/discussion thread .. maybe set up a chat
this is “blowing” up right now

there are some suggestions.. but if it’s truly OSS the maintainers should decide in an open way

Requirements
Enter the requirements that would warrant success for this issue.
