86%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is an efficient, highly actionable QuickLook reference: complete executable Swift examples for each API, a genuinely useful Common Mistakes section, and a review checklist for verification. Advanced patterns are correctly offloaded to a real, well-described one-level-deep reference file, with only minor token overhead from the redundant table of contents.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Each section opens with a single earning sentence ("For multi-file carousels, custom navigation transitions, or fine-grained preview control, use `QLPreviewController`") and the bulk is complete code, matching anchor 4 (efficient, minor trimmable instances). Not 5 because the redundant 'Contents' table of contents and a few restating sentences (the intro repeats the description) could be trimmed. | 4 / 5 |
Actionability | Four complete, copy-paste-ready Swift examples ("DocumentRowView" with `.quickLookPreview($previewURL)`, "DocumentPreviewCoordinator" with full `QLPreviewControllerDataSource` conformance, the "ThumbnailLoader" actor with `NSCache` caching, and "PreviewableDocument") plus a concrete Common Mistakes section with fixes ("always pass environment `@Environment(\.displayScale)`"). This matches anchor 5: fully executable examples covering the common cases. | 5 / 5 |
Workflow Clarity | This is a per-use-case patterns skill, not a multi-step pipeline; selection guidance ("For multi-item carousels... use `QLPreviewController`") and a validation-style "Review Checklist" ("Are target files downloaded locally before passing to QuickLook?") provide most checkpoints, matching anchor 4. Not 5 because there are no explicit feedback loops, and not below 4 since no destructive or batch operations are involved and the checklist supplies the verification steps. | 4 / 5 |
Progressive Disclosure | The body is a clear, well-navigated overview (contents list, per-topic sections, ~150 lines), and advanced material is split into a single well-signaled one-level-deep reference — "[QuickLook Patterns](references/quicklook-patterns.md) — SwiftUI custom preview sheets, zoom transitions, and thumbnail caching" — which exists in the bundle and matches its description. This matches anchor 5: appropriate split, clear navigation, references one level deep. | 5 / 5 |
