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-structured, actionable reference of UI-polish principles with executable CSS and concrete numeric guidance. It is held at 4 across dimensions by minor editorial padding, some guidance-only sections, the absence of explicit feedback loops, and no progressive disclosure into deeper reference files.
Suggestions
Trim the provenance line ('Source: salvaged from stale community PR #1659 by linus707') and the opening sentence that repeats the frontmatter description to tighten conciseness.
Add concrete CSS snippets for the optical-alignment and hit-area principles (e.g., an expanded ::before hit-area example) so every principle has copy-paste-ready code.
Move the per-principle detail (full CSS blocks, extended motion guidance) into a reference file referenced one level deep from SKILL.md to improve progressive disclosure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence, using tight principles with copy-paste snippets rather than explaining basic CSS, but small editorial asides ('The point is optical coherence, not formula worship') and the provenance line ('Source: salvaged from stale community PR #1659 by linus707') plus a repeated opening sentence could be trimmed. | 4 / 5 |
Actionability | It provides executable CSS (font smoothing, image outlines, transition scope) and concrete numeric rules (40x40px hit area, scale(0.96), 150ms exit, outer radius = inner radius + padding), but several principles (optical alignment, motion defaults, hit areas) are guidance rather than copy-paste code, leaving minor gaps versus the fully-executable anchor 5. | 4 / 5 |
Workflow Clarity | The flow from 'When to Use' through 'Core Principles' to a 'Review Output' before/after table and a 'Checklist' gives a clear, sequenced review process with the checklist acting as a validation checkpoint; it stops short of anchor 5 because there are no explicit feedback/retry loops. | 4 / 5 |
Progressive Disclosure | The file is well-organized into clearly headed sections and is self-contained with no external references (none exist in the bundle), but at ~145 lines it is somewhat long for a single SKILL.md without any one-level-deep references that could offload detail, so it sits below the ideal anchor 5. | 4 / 5 |
