Quality

Content

78%Weight 40%Scale 1-5

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

The body is a strong, highly actionable material catalog with executable examples throughout and good selection guidance. Its weakness is progressive disclosure: a large inlined API reference that would benefit from being split into reference files.

Suggestions

Move the exhaustive per-material property listings (especially MeshPhysicalMaterial's clearcoat/transmission/sheen/iridescence/anisotropy keys and the built-in uniforms reference) into a references/ file, keeping SKILL.md to a quick-start, the comparison table, and one compact example per material.

Add a short 'choose then verify' note (e.g. render a test frame and confirm the material looks correct under scene lighting) to give the configuration workflow an explicit checkpoint.

Trim minor editorial padding like 'Recommended for realistic results' and 'Full control - no built-in uniforms/attributes' so every line adds information Claude doesn't already have.

Dimension	Reasoning	Score
Conciseness	The body is largely lean — code blocks with terse inline comments and brief one-line intros like 'No lighting calculations. Fast, always visible.' — with only minor padding ('Recommended for realistic results', 'Full control - no built-in uniforms/attributes') that could be trimmed.	4 / 5
Actionability	Every material type ships a complete, copy-paste-ready constructor example with its properties, plus targeted worked examples (glass, car paint) and a built-in-uniforms reference, covering the common cases fully.	5 / 5
Workflow Clarity	A comparison table and Quick Start make material selection unambiguous and the Performance Tips give ordered guidance; as a non-destructive reference skill it avoids the destructive-cap, but lacks any explicit verify-the-render feedback loop.	4 / 5
Progressive Disclosure	Section structure is clear and navigable, but the ~540-line body inlines a full per-material property API reference (e.g. MeshPhysicalMaterial's clearcoat/transmission/sheen keys, built-in uniforms) that belongs in reference files, and no bundle files exist to absorb it.	3 / 5

Description

83%Weight 40%Scale 1-5

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

The description is well-constructed: third person, concise, and explicitly pairs a concrete 'what' with a trigger-laden 'when' clause. Its main weakness is overlap with sibling Three.js skills on shared trigger terms.

Dimension	Reasoning	Score
Specificity	Names the domain plus several concrete items ('PBR, basic, phong, shader materials') and concrete actions ('styling meshes, working with textures, creating custom shaders, optimizing material performance'), with minor coverage gaps rather than comprehensive enumeration.	4 / 5
Completeness	Explicitly answers 'what' (Three.js materials - PBR, basic, phong, shader materials, material properties) and 'when' with concrete trigger phrases ('Use when styling meshes, working with textures, creating custom shaders, or optimizing material performance').	5 / 5
Trigger Term Quality	Includes natural terms users would say ('custom shaders', 'textures', 'materials', 'styling meshes') but misses common synonyms and file/extension variations, fitting good-but-not-comprehensive keyword coverage.	4 / 5
Distinctiveness Conflict Risk	The 'Three.js materials' niche is clearly distinct, but overlap risk remains with closely related sibling skills (threejs-shaders, threejs-textures, threejs-lighting) that share triggers like 'custom shaders' and 'textures'.	4 / 5
