guide-macos-spm-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

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a tight, actionable guide with executable commands, explicit validation checkpoints, and error-recovery guidance. Progressive disclosure is good but has a minor gap: scaffold.md exists yet is not linked from the body.

Suggestions

Link references as markdown links (e.g. [references/packaging.md](references/packaging.md)) and add a pointer to references/scaffold.md, which exists but is never referenced from the body.

De-duplicate the Templates list against the Two-Step Workflow so each script's purpose is stated only once, trimming the conciseness redundancy.

In the Minimum E2E Example, note that `sed -i ''` is macOS-specific so the example is copy-paste-correct on the target platform.

DimensionReasoningScore

Conciseness

Lean body with no padding about what SwiftPM or Xcode is; however the Templates section re-lists filenames already named in the workflow, a minor redundancy that could be trimmed.

4 / 5

Actionability

Fully executable copy-paste-ready bash (cp, sed, swift build, codesign, spctl, stapler) plus concrete script invocations, and a failure-recovery table covering common cases.

5 / 5

Workflow Clarity

Clearly sequenced two-step workflow and a dedicated Validation Checkpoints section with commands after packaging, signing, and notarization, plus feedback loops via the Common Notarization Failures recovery table.

5 / 5

Progressive Disclosure

Overview cleanly points to one-level-deep references (packaging.md, release.md) and a templates bundle (verified to exist), but references/scaffold.md is unreferenced and reference paths are not rendered as markdown links.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is third-person, concrete, and explicitly pairs a clear "what" with a multi-clause "when". It covers the scaffold→build→package→sign→notarize→appcast lifecycle comprehensively and occupies a distinct niche.

DimensionReasoningScore

Specificity

Lists multiple concrete actions across the full lifecycle — "Scaffold, build, and package", "SwiftPM targets/resources", "custom .app bundle assembly script", "signing/notarization/appcast steps" — giving comprehensive coverage rather than minor gaps.

5 / 5

Completeness

Explicitly answers both "what" (scaffold/build/package SwiftPM macOS apps without Xcode) and "when" ("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") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Strong natural terms ("macOS app", "SwiftPM", "Xcode project", ".app bundle", "signing/notarization", "appcast") a user would say, but missing common synonyms and file extensions like Package.swift or .swift.

4 / 5

Distinctiveness Conflict Risk

Clear niche — SwiftPM-based macOS apps without an Xcode project — with distinct triggers that would not fire for general Swift or Xcode-centric skills; minimal conflict risk.
