15%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a tidy but generic glossary of 3D graphics concepts: it describes what frustum culling, light types, and camera types are — knowledge Claude already has — without a single piece of executable or project-specific guidance. It reads as reference material for a human beginner rather than a skill that changes what Claude does.
Suggestions
Strip the textbook concept tables (shader/light/camera/collision-shape taxonomies) and replace them with decision-driving content Claude doesn't know: project-specific conventions, engine-specific settings, or measured performance heuristics.
Add concrete, actionable artifacts — e.g., a shader skeleton, a LOD-selection formula tied to target platform, or a camera-collision implementation pattern — so the skill instructs rather than describes.
Delete the boilerplate "When to Use" section ('This skill is applicable to execute the workflow or actions described in the overview') and either split the domains into references/ files (shaders.md, physics.md) or condense the whole skill to a short overview.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is compact in form but nearly every section restates textbook knowledge Claude already has: "**Vertex** | Position, normals", "**Point** | Lamps, torches", "**Frustum culling** | Don't render off-screen", camera-type and light-type tables. Matches 'Noticeably verbose; several unnecessary explanations or padded sections'; not 1 because it avoids long padded prose, not 3 because there is essentially no non-obvious content earning its tokens. | 2 / 5 |
Actionability | There is no code, command, or executable guidance anywhere — only descriptive tables ("Mesh colliders everywhere → Simple shapes", LOD percentage table) and the directive "Simple colliders, complex visuals" with no means to apply it. Matches anchor 1 exactly: 'only describes rather than instructs'; not 2 because even high-level steps toward a concrete outcome are absent. | 1 / 5 |
Workflow Clarity | No actionable workflow is sequenced: the numbered "rendering pipeline stages" describe GPU hardware stages, not instructions, and the closing "When to Use" section is filler boilerplate ('This skill is applicable to execute the workflow or actions described in the overview'). Matches 'Steps missing or incoherent; no sequence'; not 2 because no rough task sequence exists even with gaps. | 1 / 5 |
Progressive Disclosure | The body is well-sectioned with headers and tables, but it is a monolithic inline survey of seven domains (rendering, shaders, physics, cameras, lighting, LOD, anti-patterns) with no references or navigation to deeper material, and it exceeds the 50-line simple-skill exception. Matches 'Some structure but content that should be separate is inline'; not 4 because domains like shaders or physics clearly warrant their own reference files. | 3 / 5 |
