Asking contributors to first make sure there is an approved requirement before creating a PR sounds like a great idea regardless of the use of LLM.

But another issue is - AI disclosure (agent, model etc). I'm sure others tried similar approaches, but in case this is not common knowledge - I tried to see what happens if you ask agents to disclose themselves in the PR description / comments in a rule file.

It seems to work pretty well as most AI "assisted" PRs will be opened by agents using the gh cli or MCP on behalf of the user. (Of course this can be bypassed, but for someone who doesn't mind disclosing or doesn't care, this is a good step forward)

Example: https://github.com/arnica/depsguard/blob/main/AGENTS.md#ai-d...

(so far worked on PRs from both Claude Code and Codex - both got a footer disclosure of the agent name and model)
