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

A well-organized reference-routing skill: a lean overview, a fully executable quick-start example, and a clearly leveled set of one-level-deep reference files covering topics from getting started to WebGPU. Its main limitation is the absence of any inline validation/feedback guidance, though none is strictly required for this non-destructive skill.

Dimension	Reasoning	Score
Conciseness	The body is lean — mostly concise reference pointers and one code block — with only minor over-explanation such as the opening line 'a cross-browser WebGL/WebGPU library' that defines something Claude already knows.	4 / 5
Actionability	The Quick Start Pattern provides copy-paste-ready, executable Three.js code (scene/camera/renderer/lights/animation loop) covering the common case, while advanced topics are delegated to concrete reference paths; minor gap is no inline examples for advanced cases.	4 / 5
Workflow Clarity	The Quick Start lays out a clear numbered sequence (1. Scene/Camera/Renderer, 2. Add Objects, 3. Add Lights, 4. Animation Loop) and the Progressive Learning Path gives unambiguous topic-to-reference routing; no validation checkpoints are needed since the skill involves no destructive or batch operations.	4 / 5
Progressive Disclosure	Clear overview body with well-signaled one-level-deep references (references/01 through 16), each labeled with a topic and one-line description, all verified to exist as real files; content is appropriately split and easy to navigate.	5 / 5

Description

100%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.

A highly specific, well-structured description that comprehensively covers capabilities, actions, natural trigger terms, and explicit use-when guidance in third person. It is dense and somewhat keyword-stuffed but every element is concrete rather than vague fluff.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete capabilities ('scenes, cameras, geometries, materials, lights, animations, model loading (GLTF/FBX), PBR materials, shadows, post-processing (bloom, SSAO, SSR), custom shaders, instancing, LOD, physics, VR/XR') and concrete actions ('create, build, animate, render 3D scenes/models') with comprehensive coverage.	5 / 5
Completeness	Explicitly answers both 'what' (Capabilities + Actions sections) and 'when' via the 'Use when: creating 3D visualizations, building WebGL/WebGPU apps, loading 3D models, adding animations, implementing VR/XR, creating interactive graphics, building product configurators' trigger clause.	5 / 5
Trigger Term Quality	Comprehensive natural keyword coverage including synonyms and library names a user would actually say ('Three.js, WebGL, WebGPU, 3D graphics, GLTF, FBX, OrbitControls, WebXR, VR, AR, product configurator, data visualization, architectural walkthrough').	5 / 5
Distinctiveness Conflict Risk	Occupies a clear niche (3D web graphics via Three.js/WebGL/WebGPU) with distinct, library-specific triggers and minimal overlap risk with other skills.	5 / 5
