Kidding (somewhat) but seriously: if you're not contributing PRs across the stack, to repos you don't own, you're doing it wrong. I don't mean blindly vibe coding changes. I'm saying: it takes less time for you to have AI figure out where the bug or missing gap is and fix it, you review the changes, have it then submit the PR, than it does for you to waste time trying to Slack them and ask for someone to eventually find the issue and fix it and land it: 1 day vs weeks, if that. Don't let org boundaries hold you back anymore.
