68%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.
A rich, well-structured knowledge skill with dense, mostly executable guidance and clear navigation. Its weakest dimension is workflow clarity, which is inherent to its reference nature rather than a procedural defect.
Suggestions
Tighten the evocative prose and WWDC pull-quotes where they duplicate the adjacent bullet guidance to push conciseness toward 5.
Complete the pointerdown example (§2) with the actual velocity/position-history tracking instead of a '// ...' placeholder so all code is copy-paste ready.
Add an explicit 'When implementing a feature, follow these steps in order: pick the relevant principle → apply the concrete value from Quick Reference → verify reduced-motion/contrast fallbacks' checklist to give the skill a lightweight sequenced workflow with verification.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Largely lean and information-dense (bullets, tables, executable code) with little concept-padding Claude already knows, but retains some evocative prose and illustrative WWDC quotes that could be trimmed; not a 5 because of those minor over-explanations. | 4 / 5 |
Actionability | Provides concrete, mostly copy-paste-ready code (spring animate, project, rubberband, typography, reduced-motion media queries) and a Quick Reference table of concrete values; falls short of 5 because the pointerdown snippet leaves velocity tracking as a '// ...' placeholder. | 4 / 5 |
Workflow Clarity | This is a knowledge/principles reference rather than a procedural workflow; the Process section (§17) gives high-level design guidance with no explicit validation checkpoints, and no sequenced operational steps exist (no destructive/batch cap applies). | 3 / 5 |
Progressive Disclosure | Well-organized into 17 numbered sections plus a Quick Reference table for easy navigation; no bundle files exist and the content is self-contained, with only minor organization gaps (e.g., the lengthy §16 foundations could conceivably be a separate reference). | 4 / 5 |
