Can I use this for Sparkle auto-updates?

Absolutely. The skill generates EdDSA signatures and provides the exact XML structure needed to update your Sparkle appcast.xml file.

How does it automate DMG creation?

It uses hdiutil to create a compressed UDZO format DMG and automatically includes a symlink to the /Applications folder for a standard drag-and-drop installation experience.

Does it support GitHub integration?

Yes, it utilizes the GitHub CLI (gh) to create releases, generate release notes, and upload both DMG and zip assets to your repository.

Does this skill handle Apple Notarization?

Yes, it includes specialized commands for submitting DMGs to Apple's notarization service and stapling the resulting ticket for offline verification.

What credentials are required to use this skill?

You will need a valid Apple Developer ID Application certificate, an Apple ID with a Team ID, and an app-specific password for the notarization service.
