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 material types and capabilities, includes natural trigger terms that developers would use, and provides explicit 'Use when' guidance with concrete scenarios. The description is concise yet comprehensive.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions and material types: 'PBR, basic, phong, shader materials, material properties' along with specific use cases like 'styling meshes, working with textures, creating custom shaders, optimizing material performance'.

3 / 3

Completeness

Clearly answers both what (Three.js materials - PBR, basic, phong, shader materials, material properties) and when (Use when styling meshes, working with textures, creating custom shaders, or optimizing material performance) with explicit trigger guidance.

3 / 3

Trigger Term Quality

Includes natural keywords users would say: 'Three.js', 'materials', 'PBR', 'phong', 'shader', 'textures', 'meshes', 'custom shaders'. These cover common terminology developers use when working with 3D graphics materials.

3 / 3

Distinctiveness Conflict Risk

Highly specific to Three.js materials domain with distinct triggers like 'PBR', 'phong', 'shader materials', 'textures', 'meshes'. Unlikely to conflict with other skills unless there are multiple Three.js skills, in which case 'materials' clearly carves out this niche.

Implementation

100%

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

This is an exemplary reference skill that efficiently covers Three.js materials with comprehensive, executable code examples. The content is well-organized with a logical progression from simple to complex materials, includes practical real-world examples (glass, car paint), and provides performance optimization guidance. The material comparison table and consistent section structure make it easy to navigate.

DimensionReasoningScore

Conciseness

The content is highly efficient with no unnecessary explanations of basic concepts. Every section provides direct, actionable code examples without verbose preambles or explanations Claude would already know.

3 / 3

Actionability

Excellent executable code throughout - all examples are complete, copy-paste ready JavaScript/GLSL. Includes practical examples like glass material and car paint with specific property values.

3 / 3

Workflow Clarity

For a reference-style skill covering material types, the organization is clear and logical. The material types table provides excellent overview, and each section follows a consistent pattern. Performance tips section includes clear guidance on when needsUpdate is required.

3 / 3

Progressive Disclosure

Well-structured with clear hierarchy: Quick Start → Overview table → Individual material types → Common properties → Advanced topics. References to related skills (textures, shaders, lighting) are clearly signaled at the end.
