macos-spm-app-packaging
Scaffold, build, and package SwiftPM-based macOS apps without an Xcode project. Use when you need a from-scratch macOS app layout, SwiftPM targets/resources, a custom .app bundle assembly script, or signing/notarization/appcast steps outside Xcode.

Quality
Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that clearly defines a specific niche (SwiftPM-based macOS apps without Xcode), lists concrete capabilities, and provides explicit trigger conditions via a well-structured 'Use when' clause. The description is concise yet comprehensive, with strong domain-specific trigger terms that would help Claude accurately select this skill from a large pool.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: scaffold, build, package SwiftPM-based macOS apps, app layout creation, SwiftPM targets/resources configuration, .app bundle assembly script, signing, notarization, and appcast steps. These are all concrete, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (scaffold, build, and package SwiftPM-based macOS apps) and 'when' (explicit 'Use when' clause listing four specific trigger scenarios: from-scratch layout, SwiftPM targets/resources, custom .app bundle assembly, or signing/notarization/appcast outside Xcode). | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'SwiftPM', 'macOS apps', 'Xcode project', '.app bundle', 'signing', 'notarization', 'appcast', 'from-scratch'. These cover the natural terms a developer working in this space would use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche: specifically targets SwiftPM-based macOS apps *without* an Xcode project. The 'outside Xcode' qualifier and specific mentions of .app bundle assembly, notarization, and appcast make it very unlikely to conflict with general Swift, iOS, or Xcode-based skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an excellent skill file that efficiently covers a complex multi-step workflow (SwiftPM app bootstrapping, building, packaging, signing, and notarization) with concrete executable commands, explicit validation checkpoints at each critical stage, and a useful troubleshooting table. The content is well-structured with progressive disclosure to external references and templates, and it respects Claude's intelligence by avoiding unnecessary explanations of underlying concepts.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient throughout. It assumes Claude knows what SwiftPM, codesign, notarization, and Gatekeeper are without explaining them. Every section serves a clear purpose with no padding or unnecessary context. | 3 / 3 |
Actionability | Provides fully executable bash commands for the end-to-end workflow, concrete validation commands, a troubleshooting table with specific symptoms and recovery steps, and explicit file paths for all templates. The minimum example is copy-paste ready. | 3 / 3 |
Workflow Clarity | The two-step workflow is clearly sequenced, and dedicated validation checkpoints are provided after packaging, signing, and notarization—each with explicit commands and expected outcomes. The troubleshooting table adds error recovery feedback loops for notarization failures. | 3 / 3 |
Progressive Disclosure | The SKILL.md serves as a clear overview with well-signaled references to `references/packaging.md`, `references/release.md`, and the `assets/templates/` directory. Template descriptions are listed concisely without inlining their full content. Navigation is one level deep and clearly organized. | 3 / 3 |
