Quality

Content

82%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.

A high-quality, code-rich guideline skill with executable examples, clear anti-patterns, and strong decision rules. Its only real gaps are minor over-explanation and a monolithic body that could offload some detail into reference files.

Suggestions

Tighten the explanatory prose around the Flex Column Scroll Trap (e.g. the opening 'single most common layout bug' sentence and duplicated rationale in prose + table) to push conciseness toward 5.

Consider moving the lengthy 'Flex Column Scroll Trap' subsection into a references file (e.g. references/flex-scroll-trap.md) with a short summary + link in SKILL.md to improve progressive disclosure.

DimensionReasoningScore

Conciseness

The body is mostly lean and action-oriented with minimal explanation of basics, but contains some explanatory prose (e.g. 'This is the single most common layout bug in this codebase') and rationale tables that could be trimmed slightly, fitting 'efficient; minor instances of over-explanation'.

4 / 5

Actionability

Fully executable, copy-paste-ready Svelte examples with specific utility classes (e.g. 'flex-1 min-h-0 overflow-hidden'), before/after pairs, and anti-patterns covering the common cases (scroll trap, disabled states, primitive overrides).

5 / 5

Workflow Clarity

As a guideline skill it has clear decision rules and a well-explained fix with a per-utility rationale checklist, but it is not a multi-step process with explicit validation checkpoints, so it sits at 4 rather than 5.

4 / 5

Progressive Disclosure

Well-organized into clear sections with one clearly-signaled, one-level-deep external reference (../ui-design/references/component-system.md); however all substantive content is inlined in a ~190-line body rather than split into reference files, keeping it at 4.

Description

70%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.

A concise, third-person description with strong natural trigger phrases and an explicit 'Use for' clause. Its main weakness is a terse 'what' that lists the domain and a couple of tools rather than multiple concrete capabilities.

Suggestions

Expand the 'what' to name a few more concrete capabilities (e.g. 'combine classes conditionally with cn(), build component variants with tailwind-variants, fix flex scroll layouts') to lift specificity toward 5.

Add a couple more natural trigger terms users say (e.g. 'center this', 'make it responsive', 'grid layout') to round out trigger coverage.

DimensionReasoningScore

Specificity

Names the domain and a couple of concrete tools ("CSS and Tailwind, cn(), flex layouts") but does not enumerate multiple specific actions; coverage is not comprehensive, fitting the '1-2 concrete actions' anchor rather than the 'several specific actions' anchor above.

3 / 5

Completeness

Both 'what' (CSS/Tailwind, cn(), flex layouts) and an explicit 'when' ("Use for...") with concrete trigger phrases are present; the 'what' is terse rather than fully spelled out, keeping it at 4 rather than 5.

4 / 5

Trigger Term Quality

Strong natural phrasing ("style this", "fix the CSS", "add classes", "not scrolling", "overflow") gives good keyword coverage, but a few common natural terms (e.g. "center this", "responsive", "grid") are missing, so it stops short of comprehensive.

4 / 5

Distinctiveness Conflict Risk

The CSS/Tailwind/cn() niche is mostly distinct with specific triggers, but the skill itself points to a sibling ui-design skill, indicating minor overlap risk with a closely related skill.
