Just thinking, could it be that your coworker used Raycast to spin up a codex to review and fix the typo on the PR? And that comment was added by Raycast?
GitHub's docs and blog make use of and feature Raycast, and I'm willing to bet that's the result of a partnership, and not because someone writing docs and blog posts happens to think Raycast is great and keeps bringing it up.
So I think they’re injecting this as a tip on using Copilot, that just happens to be their integration with Raycast.
I have no idea what their actual partnership with Raycast looks like, maybe this is part of what they offered them? But it’s not a traditional link to another product ad like it appears to be from Raycast being a link.
