frontend-design

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

Quality

Content

78%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 lean, well-structured single-file skill that gives genuinely actionable aesthetic direction through named do's and don'ts rather than generic platitudes. It could be tightened slightly (motivational closing lines) and its actionability nudged up with one small illustrative example, but nothing needs to be moved to separate files.

Suggestions

Trim motivational filler ('Remember: Claude is capable of extraordinary creative work. Don't hold back...') to free tokens for instructional content.

Add one compact before/after example (e.g., a two-line CSS variable palette or a font-pairing) to lift actionability from concrete hints to copy-paste-ready guidance.

DimensionReasoningScore

Conciseness

The body is directive and assumes competence — it never explains what HTML or CSS is — but carries minor motivational padding ('Remember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created...'). Fits anchor 4 (minor trimming possible); not 5 because a few closing lines earn no instructional value, and not 3 because there is no genuine over-explanation.

4 / 5

Actionability

Instruction-only skill with concrete, named guidance: fonts to avoid ('Inter, Roboto, Arial, system fonts'), a cliché to reject ('purple gradients on white backgrounds'), and specific techniques ('animation-delay', 'staggered reveals', 'gradient meshes, noise textures', 'Motion library for React'). Per the scoring notes, absence of code is not penalized if guidance is actionable — it is, but it stops short of illustrative snippets, so anchor 4 rather than 5.

4 / 5

Workflow Clarity

Clear two-phase sequence: 'Before coding, understand the context and commit to a BOLD aesthetic direction' (purpose, tone, constraints, differentiation) followed by 'Then implement working code'. Validation checkpoints are absent but inapplicable — the skill involves no destructive or batch operations — so the cap does not apply; anchor 4 rather than 5 because no review/refinement checkpoint closes the loop.

4 / 5

Progressive Disclosure

A single ~37-line SKILL.md with no bundle files (no references/, scripts/, or assets/ exist) and two well-organized sections ('## Design Thinking', '## Frontend Aesthetics Guidelines'). Per the judging guideline, a skill under 50 lines with no need for external references scores 5 with well-organized sections.

Description

86%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 strong description with explicit what-and-when structure and excellent natural trigger coverage. Its only weakness is that the capability statement stays at the level of broad verbs (create/generate) rather than distinct concrete actions, which slightly limits specificity.

Suggestions

Enumerate concrete capabilities (e.g., 'design landing pages and dashboards, apply cohesive typography and color systems, build animated micro-interactions') instead of relying solely on 'create' and 'generates'.

DimensionReasoningScore

Specificity

Names the domain (frontend interfaces) with two broad actions — 'Create distinctive, production-grade frontend interfaces' and 'Generates creative, polished code and UI design' — but does not enumerate several distinct concrete actions. Matches the 'domain plus 1-2 concrete actions' anchor; below 4 because the action verbs stay generic (create/generate) rather than listing specific capabilities.

3 / 5

Completeness

Explicitly answers both: what ('Create distinctive, production-grade frontend interfaces... Generates creative, polished code and UI design that avoids generic AI aesthetics') and when ('Use this skill when the user asks to build web components, pages, artifacts, posters, or applications'). Matches the anchor-5 example structure exactly.

5 / 5

Trigger Term Quality

Comprehensive natural terms with synonyms: 'web components, pages, artifacts, posters', 'websites, landing pages, dashboards, React components, HTML/CSS layouts', and 'styling/beautifying any web UI'. These are exactly the phrases users would naturally say; no significant terms missing, so it fits the top anchor rather than 4.

5 / 5

Distinctiveness Conflict Risk

Clear niche — high-design-quality frontend creation that 'avoids generic AI aesthetics' — with triggers specific to building/styling web UI. However 'styling/beautifying any web UI' is somewhat broad, giving minor overlap risk with closely related general web-development skills, which matches anchor 4 ('mostly distinct; minor overlap risk') rather than anchor 5's 'minimal conflict risk'.
