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 content is a highly actionable, executable reference with lean code-first examples and a clear quick-start sequence. Its main weakness is structure: the entire API catalog lives inline in SKILL.md with no progressive disclosure into separate reference files.

Suggestions

Move the detailed constructor-signature catalog (Built-in Geometries, BufferAttribute Types) into a references/ file and keep SKILL.md as a quick-start overview with one-level-deep links.

Trim repeated inline parameter-list comments where the signature is self-explanatory to reduce token load.

Consider a short validation/verification note for runtime geometry changes (e.g., set needsUpdate and recompute normals) to strengthen workflow clarity for the mutating-geometry sections.

Dimension	Reasoning	Score
Conciseness	The body is mostly lean executable code with minimal conceptual padding and assumes Claude's competence, but at ~545 lines with repeated full constructor-signature comments it could be trimmed in places.	4 / 5
Actionability	Code is fully executable and copy-paste ready across built-in shapes, BufferGeometry, points, lines, instancing, and utilities, covering the common cases comprehensively.	5 / 5
Workflow Clarity	Quick Start gives a clear import → geometry → mesh → add-to-scene sequence, and geometry creation is not a destructive/batch operation requiring validation, but no explicit multi-step workflow or checkpoints exist beyond the quick start.	4 / 5
Progressive Disclosure	Section headers provide reasonable structure, but all detailed API reference content is inlined in one ~545-line file with no bundle files (references/, scripts/, assets/ are absent) and no one-level-deep external references to split out the bulk material.	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-structured, explicitly covering both what the skill does and when to use it with natural trigger phrases. It is specific and distinct within the Three.js skill family, with only minor room for more action-oriented verbs and synonym coverage.

Dimension	Reasoning	Score
Specificity	Lists several concrete capability areas ("built-in shapes, BufferGeometry, custom geometry, instancing") but they are nouns rather than distinct named actions, leaving minor coverage gaps versus a fully action-oriented list.	4 / 5
Completeness	Explicitly answers both what ("Three.js geometry creation - built-in shapes, BufferGeometry, custom geometry, instancing") and when ("Use when creating 3D shapes, working with vertices, building custom meshes, or optimizing with instanced rendering") with concrete triggers.	5 / 5
Trigger Term Quality	Natural trigger phrases like "creating 3D shapes", "working with vertices", "building custom meshes", and "optimizing with instanced rendering" match what users would say, though a few synonyms/variants are missing.	4 / 5
Distinctiveness Conflict Risk	"Three.js geometry" carves a clear niche with distinct triggers, but sibling skills (threejs-shaders for vertex manipulation, threejs-fundamentals for Object3D) create minor overlap risk.	4 / 5
