How does this handle macOS 'Resource Busy' errors in CI/CD?

It implements a progressive escalation strategy using multi-stage unmount attempts and verification to resolve race conditions during DMG creation in GitHub Actions.

Which desktop platforms are supported by this skill?

The skill provides patterns and automation for macOS (DMG bundles), Windows (MSI installers via WiX), and Linux (DEB packages).

Does it support automated updates for package managers?

Yes, it includes guidance for automating Homebrew formula updates via repository_dispatch for streamlined macOS distribution.

Can it help with supply chain security?

Yes, it includes built-in patterns for SLSA attestations to verify the integrity of your software artifacts throughout the build process.

Is this skill specific to Rust applications?

While it features specific optimizations for Rust (like Cargo workspace asset handling and winres icon embedding), the packaging patterns are applicable to most desktop applications.
