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

Discovery

92%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a strong skill description that clearly communicates both what the skill does and when to use it, with rich trigger terms covering many natural user phrasings. The description's main weakness is its broad scope which could overlap with other coding or framework-specific skills, though the emphasis on design quality and avoiding generic AI aesthetics provides a useful differentiator. The third-person voice is used correctly throughout.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions and outputs: 'web components, pages, artifacts, posters, applications' with further examples like 'websites, landing pages, dashboards, React components, HTML/CSS layouts'. Also specifies the quality dimension: 'production-grade', 'polished code and UI design', 'avoids generic AI aesthetics'.

3 / 3

Completeness

Clearly answers both 'what' (create distinctive, production-grade frontend interfaces with high design quality, generates creative polished code) and 'when' (explicit 'Use this skill when...' clause with specific trigger scenarios like building web components, pages, dashboards, styling/beautifying web UI).

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: 'web components', 'pages', 'landing pages', 'dashboards', 'React components', 'HTML/CSS layouts', 'styling', 'beautifying', 'web UI', 'posters', 'artifacts', 'websites', 'applications'. These are terms users naturally use when requesting frontend work.

3 / 3

Distinctiveness Conflict Risk

While it focuses on frontend/UI with a design quality emphasis, the scope is quite broad ('web components, pages, applications') which could overlap with general coding skills or specific framework skills. The 'high design quality' and 'avoids generic AI aesthetics' angle provides some distinction, but the breadth of covered items increases conflict risk.

Implementation

22%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This skill provides high-level design philosophy and aesthetic direction but critically lacks actionable, executable guidance. It reads more like a design manifesto than a technical skill—there are no code examples, no step-by-step workflows, and no concrete implementation patterns. The anti-pattern list (what NOT to do) is useful but insufficient without showing what TO do in code.

Suggestions

Add at least 2-3 executable code examples (e.g., a complete HTML/CSS snippet for a minimalist dashboard card, a React component with specific styling) to demonstrate the aesthetic principles in practice.

Define a clear step-by-step workflow: e.g., 1) Determine aesthetic direction, 2) Choose typography/colors, 3) Build layout skeleton, 4) Add interactions, 5) Review against anti-patterns checklist.

Replace the vague 'Examples' section with actual before/after code showing a generic AI-style component transformed into a distinctive design.

Add validation steps such as a checklist to verify the output doesn't fall into the listed anti-patterns (e.g., 'Verify: no Inter/Roboto fonts, no purple gradients, layout is non-standard').

DimensionReasoningScore

Conciseness

The skill has some unnecessary verbosity—the 'When to Use This Skill' section largely repeats the description, and the DO/DON'T lists could be tighter. The tone options list is long but arguably useful as a creative prompt. Some sections explain things Claude would already understand (e.g., 'What problem does this interface solve? Who uses it?').

2 / 3

Actionability

Despite being a frontend design skill, there is zero executable code—no HTML, CSS, React snippets, or concrete implementation patterns. The content is entirely descriptive guidance ('make bold choices', 'pay exceptional attention to aesthetic details') with no copy-paste-ready examples. The 'Examples' section describes aesthetics in bullet points rather than showing actual code.

1 / 3

Workflow Clarity

There is no clear sequenced workflow for building a frontend interface. The skill lists considerations (purpose, tone) and rules but never defines a step-by-step process from start to finished output. There are no validation checkpoints or feedback loops for ensuring design quality or code correctness.

1 / 3

Progressive Disclosure

The content is organized into logical sections with clear headers, which is good. However, with no bundle files and no references to external resources, all content is inline. For a skill of this scope (covering many UI types and aesthetic directions), deeper reference materials for specific frameworks or patterns would be beneficial.
