Introducing Umbrel App Store agent skills.

Ask Claude Code/Codex: "See getumbrel/umbrel-apps repo and build (or test/update/submit) an Umbrel app".

After approving 350+ apps and 5,000+ app updates, we've condensed all those learnings into 4 hyper-focused agent skills right in our app store repo.

So yeah, that's the entire barrier to building high-quality self-hosted apps now. 🫡
