generate-sparkle-appcast

Quick Review

The skill provides a reasonable overview of generating a Sparkle appcast for Mos releases with bilingual release notes. However, descriptionCoverage is hindered by vague invocation instructions (the actual script path and exact command syntax could be clearer). taskKnowledge is moderate—the workflow is outlined, but critical implementation details (how git changes are parsed, how the appcast XML is constructed, signature generation) are assumed to be in the referenced script. Structure is acceptable for a single-script skill but lacks explicit confirmation steps or error handling guidance. Novelty is low: this automates a specific but straightforward release task (running a script, copying files) that a CLI agent could handle with moderate effort; the main value is encapsulating project-specific paths and Sparkle conventions rather than solving a complex or token-intensive problem.
