Quality

Discovery

67%

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 description has a solid structure with explicit 'Use when' guidance and identifies the specific technology stack. However, it lacks concrete action verbs describing what the skill actually does (install, configure, customize) and could benefit from more natural trigger terms users would say when needing this skill.

Suggestions

Add specific concrete actions like 'install components', 'customize themes', 'configure component variants', or 'set up shadcn/ui in a project'

Include more natural trigger terms users might say: 'shadcn', 'component library', specific component names like 'button', 'dialog', 'form', 'dropdown'

Dimension	Reasoning	Score
Specificity	Names the domain (shadcn/ui, Radix UI, Tailwind CSS) and mentions 'UI components' and 'design systems', but doesn't list specific concrete actions like 'install components', 'customize themes', or 'configure variants'.	2 / 3
Completeness	Clearly answers both what ('implementing shadcn/ui - accessible UI components built with Radix UI and Tailwind CSS') and when ('Use when building user interfaces, adding UI components, or implementing design systems in React-based applications').	3 / 3
Trigger Term Quality	Includes relevant terms like 'shadcn/ui', 'UI components', 'Radix UI', 'Tailwind CSS', and 'React', but misses common variations users might say like 'shadcn', 'component library', 'button', 'dialog', 'form components', or specific component names.	2 / 3
Distinctiveness Conflict Risk	The specific mention of 'shadcn/ui' and 'Radix UI' provides some distinctiveness, but 'building user interfaces' and 'adding UI components' are generic enough to potentially conflict with other UI/component library skills.	2 / 3

Implementation

64%

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

This is a highly actionable skill with excellent, executable code examples covering the full shadcn/ui component library. However, it's overly verbose for a skill file - the extensive inline component catalog would be better served by progressive disclosure to separate reference files. The workflow lacks explicit validation checkpoints that would help catch setup issues early.

Suggestions

Split component examples into a separate COMPONENTS.md reference file, keeping only 2-3 key examples in the main skill

Add validation checkpoints to the setup workflow (e.g., 'Verify: Run `npm run dev` and check for Tailwind styles loading')

Remove the introductory paragraph explaining what shadcn/ui is - Claude can infer this from context and the description field

Convert the Implementation Checklist into a numbered workflow with explicit verification steps between major phases

Dimension	Reasoning	Score
Conciseness	The skill is comprehensive but includes some unnecessary explanations (e.g., 'shadcn/ui is a collection of beautifully-designed...' in the intro repeats what Claude would know from context). Many code examples are valuable, but the sheer volume (~700 lines) could be trimmed by referencing external docs more.	2 / 3
Actionability	Excellent executable code examples throughout - every component category has copy-paste ready TypeScript/TSX code. Installation commands, configuration files, and complete component implementations are all provided with specific, working examples.	3 / 3
Workflow Clarity	Setup steps are listed but lack explicit validation checkpoints. The 'Implementation Checklist' at the end is helpful but doesn't include verification steps between actions. For example, after 'Run npx shadcn@latest init', there's no 'Verify: check that components.json was created' step.	2 / 3
Progressive Disclosure	The skill is largely monolithic with all content inline rather than split into separate reference files. While it references external URLs (docs, GitHub), the 700+ lines of component examples could be better organized into separate files (e.g., COMPONENTS.md, THEMING.md) with the main skill providing an overview.	2 / 3
