Content

87%

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

A well-structured reference hub: lean overview, executable quick-start code, and a clearly signaled, leveled set of one-level-deep reference files that all exist on disk. The only gap is the absence of explicit validation/feedback checkpoints in the quick-start workflow.

Suggestions

Add a brief validation step to the Quick Start Pattern (e.g., confirm the canvas rendered or check for WebGL context errors) to give the workflow an explicit checkpoint.

Reduce the mild overlap between the frontmatter description and the 'When to Use This Skill' section so the body adds information rather than restating triggers.

Consider a short 'Troubleshooting / common pitfalls' pointer so error recovery is signaled alongside the quick start.

DimensionReasoningScore

Conciseness

The body is lean — a one-line intro, a bullet trigger list, a leveled reference index, and a single executable code block — with no padding or explanation of concepts Claude already knows.

3 / 3

Actionability

The Quick Start Pattern is complete, executable, copy-paste JavaScript covering scene/camera/renderer, objects, lights, and the animation loop, and reference entries point to specific topic files.

3 / 3

Workflow Clarity

The Quick Start offers a clear numbered 1–4 sequence, but there are no validation checkpoints or error-recovery feedback loops, matching the anchor where sequence is present but checkpoints are missing.

2 / 3

Progressive Disclosure

SKILL.md is a concise overview pointing to 20 verified one-level-deep reference files organized into five leveled groups, each with a topic description and no nested file chains.

Description

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.

A tight, third-person description that states concrete capabilities and gives explicit 'Use for …' trigger guidance across a broad set of natural 3D-graphics terms. It is clearly niched to Three.js and unlikely to conflict with other skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Build 3D web apps', 'custom shaders', 'PBR materials', 'VR/XR experiences', 'product configurators' — matching the anchor for several specific concrete actions.

3 / 3

Completeness

Answers both what ('Build 3D web apps with Three.js (WebGL/WebGPU)') and when via the explicit 'Use for …' trigger clause, written in third person.

3 / 3

Trigger Term Quality

Covers natural terms users would say — '3D scenes', 'animations', 'custom shaders', 'VR/XR', 'games', 'data visualizations' — with good breadth of common variations.

3 / 3

Distinctiveness Conflict Risk

The explicit 'Three.js (WebGL/WebGPU)' niche with domain-specific triggers makes it unlikely to fire for unrelated skills.
