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 excels across all dimensions. It clearly identifies the domain (3D web experiences), lists specific technologies and use cases, and includes an explicit 'Use when:' clause with natural trigger terms that developers would actually use. The description is concise yet comprehensive.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions and domains: 'building 3D experiences', 'product configurators', '3D portfolios', 'immersive websites', and names specific technologies (Three.js, React Three Fiber, Spline, WebGL). | 3 / 3 |
Completeness | Clearly answers both what (building 3D experiences, product configurators, portfolios, immersive websites) AND when with explicit 'Use when:' clause listing specific trigger terms. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: '3D website', 'three.js', 'WebGL', 'react three fiber', '3D experience'. These are exactly what developers would search for when needing this skill. | 3 / 3 |
Distinctiveness Conflict Risk | Very clear niche focused on 3D web development with distinct triggers like 'three.js', 'WebGL', 'react three fiber' that are unlikely to conflict with general web development or other skills. | 3 / 3 |
Total | 12 / 12 Passed |
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 functions as a pure index/table of contents with no substantive content in the main file. While it demonstrates good modular organization by linking to sub-skills, it fails to provide any actionable guidance, executable code, or workflow clarity in the body itself. The 'Role' and 'Capabilities' sections add little value that Claude doesn't already know.
Suggestions
Add a 'Quick Start' section with a minimal executable Three.js or R3F code example that renders a basic 3D scene
Include a decision flowchart or brief guidance on which sub-skill to consult based on the user's goal (e.g., 'For product configurators, start with #5 React Three Fiber')
Remove or drastically shorten the 'Role' description and 'Capabilities' list - these describe what Claude already knows
Add a brief workflow overview showing the typical sequence: stack selection → model pipeline → implementation → optimization
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is relatively brief but includes some unnecessary fluff like the philosophical 'Role' description about 'moments of wonder' and 'when 3D enhances vs showing off' that Claude doesn't need. The capabilities list is redundant given the sub-skill links. | 2 / 3 |
Actionability | The skill body contains zero executable code, no concrete commands, and no specific examples. It's entirely a table of contents with vague capability descriptions - all actual guidance is deferred to sub-skills. | 1 / 3 |
Workflow Clarity | There is no workflow, sequence, or process described. The numbered list is just a flat index of sub-skills with no indication of when to use what, no decision flow, and no validation steps for any 3D implementation process. | 1 / 3 |
Progressive Disclosure | The skill does link to 17 sub-skills which is good progressive disclosure structure, but the main file provides almost no overview content - it's essentially just links. There's no quick-start content or summary of key concepts before diving into references. | 2 / 3 |
