Discovery
100%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 well-crafted skill description that follows best practices. It uses third person voice, lists specific capabilities, includes a clear 'Use when...' clause with natural trigger terms, and is distinctly scoped to the Material-UI ecosystem. The inclusion of version number (v7) and MUI-specific terminology makes it highly distinguishable.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'sx prop styling', 'theme integration', 'responsive design', and 'MUI-specific hooks'. These are concrete, actionable capabilities within the MUI domain. | 3 / 3 |
Completeness | Clearly answers both what ('sx prop styling, theme integration, responsive design, MUI-specific hooks') AND when ('Use when working with MUI components, styling with sx prop, theme customization, or MUI utilities') with explicit trigger guidance. | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'MUI components', 'sx prop', 'theme customization', 'MUI utilities', 'Material-UI'. Good coverage of both the full name and common abbreviation. | 3 / 3 |
Distinctiveness Conflict Risk | Highly specific to Material-UI/MUI ecosystem with distinct triggers like 'sx prop', 'MUI components', and 'Material-UI v7'. Unlikely to conflict with generic CSS or other component library skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong MUI v7 skill with excellent actionability - nearly all code examples are executable and properly typed. The structure follows good progressive disclosure with clear navigation. Minor verbosity in explaining basic MUI concepts (what Box, Paper, Container do) could be trimmed since Claude understands these component purposes.
Suggestions
Remove explanatory comments like 'Generic container', 'Elevated surface', 'Centered content with max-width' from the Layout Components section - Claude knows what these components do
Consider removing or condensing the 'When to Use This Skill' section since it largely repeats the Purpose statement
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with good code examples, but includes some unnecessary explanations like describing what each layout component does ('Generic container', 'Elevated surface') that Claude already knows. The 'When to Use This Skill' section is also somewhat redundant given the clear purpose statement. | 2 / 3 |
Actionability | Excellent executable code examples throughout - all TypeScript snippets are copy-paste ready with proper imports, typed styles, and complete component implementations. The patterns cover real-world scenarios like forms, dialogs, and loading states with concrete, working code. | 3 / 3 |
Workflow Clarity | For a component library skill, the workflow is appropriately clear. The organization guides from basic usage to advanced patterns logically. The inline vs separate styles decision tree (< 100 lines vs >= 100 lines) provides clear guidance. No destructive operations require validation checkpoints. | 3 / 3 |
Progressive Disclosure | Well-structured with clear sections progressing from Quick Start to advanced patterns. References to additional resources (styling-guide.md, component-library.md, theme-customization.md) are clearly signaled at the end with one-level-deep links. Content is appropriately split across sections. | 3 / 3 |

Validation
