General guidance:

- Please make sure to include the @dotnet/runtime-infrastructure group as a reviewer of your PRs.
- Do not use the `pull_request` event. Use `pull_request_target` instead, as documented in [Workflows in forked repositories](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows#workflows-in-forked-repositories) and [pull_request_target](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows#pull_request_target).
Please make sure to include the @dotnet/runtime-infrastructure group as a reviewer of your PRs.

For workflows that are triggered by pull requests, refer to GitHub's documentation for the pull_request and pull_request_target events. The pull_request_target event is the more common use case in this repository as it runs the workflow in the context of the target branch instead of in the context of the pull request's fork or branch. However, workflows that need to consume the contents of the pull request need to use the pull_request event. There are security considerations with each of the events though.

Refer to GitHub's [Workflows in forked repositories](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows#workflows-in-forked-repositories) and [pull_request_target](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows#pull_request_target) documentation for more information.

To @danmoseley's question:

Are you going to put this into arcade, and if so will other repos extend this if? Is there some way to pass the setting externally to achieve the same thing but without making this less reusable? Nit only

I spent some time searching across GitHub docs and code searches, a grep.app search, and asking Copilot for best practices around this, and hard-coding either the repository name or just the repository owner name are indeed the state of the art here. Theoretically, we could set up an environment variable that would be available to all our workflow runners, and we could check that environment variable, but since I don't see anyone else doing that I think the consensus is that making this more dynamic isn't worth the effort.

For any workflow that is going to be shared across repos (or at least referenced as something that could be copied into other repos), we'd want to just check the repository_owner like we do in locker.yml. For these workflows, either approach should be fine.
