75%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 well-organized, mostly lean pattern catalog with executable code examples and specific numeric guidance. Its weaknesses are minor: redundant guidance across the Accessibility, Animation Guidelines, and Best Practices sections, dependencies on undefined custom components, and no framing that tells the reader when to apply each pattern.
Suggestions
Consolidate the overlapping guidance: prefers-reduced-motion and keyboard-navigation advice currently appears in both the Accessibility/Animation Guidelines sections and the Best Practices list — merge into one place.
Note (or inline) the <Icon> and <Illustration> component dependencies in the JSX snippets, or replace them with plain SVG/text equivalents so the code is copy-paste ready.
Add a short intro or decision cue (e.g., "match the state you're designing: loading, error, or empty") that guides pattern selection, and trim the ~100-line body toward the lean simple-skill profile.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean — a compact table, terse CSS/JSX snippets, and bullet lists with no explanation of concepts Claude already knows. Minor trimming is possible: "prefers-reduced-motion" and keyboard-navigation guidance each appear redundantly in the Accessibility/Animation Guidelines sections and again in Best Practices. | 4 / 5 |
Actionability | Provides concrete, executable artifacts (the shimmer CSS skeleton, LoadingState/ErrorState/EmptyState JSX, aria-live announcer) with specific numeric guidance (100–200ms durations, >0.5s loading threshold). Minor gaps: snippets depend on undefined <Icon> and <Illustration> components without noting that dependency. | 4 / 5 |
Workflow Clarity | As a pattern catalog rather than a multi-step process, no destructive/batch validation cap applies and the individual patterns are unambiguous to apply. However, it offers no guidance on choosing among the patterns or a suggested design sequence, keeping it below anchor 5. | 4 / 5 |
Progressive Disclosure | No bundle files exist, and the ~100-line body is well-organized into clearly headed sections with no nested references. It slightly exceeds the under-50-line simple-skill bar and lacks an overview tying the sections together or signaling when to consult each pattern. | 4 / 5 |
