Content

86%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.

A well-structured, token-efficient skill body with executable code and clear API guidance. The main gap is the conceptual-only React cleanup recipe, which would benefit from concrete code.

Suggestions

Replace the conceptual React cleanup recipe with an executable useEffect/useRef code snippet matching the specificity of Recipe #1.

Add a brief explicit checkpoint in the cleanup guidance (e.g., 'verify effect.destroy() ran on unmount in SPAs') to strengthen workflow clarity.

Consider noting the three.js version constraint inline (e.g., r134) alongside the existing pitfalls to prevent silent breakage.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, with no padding explaining what WebGL or three.js are; every section earns its place.

5 / 5

Actionability

Recipe #1 is copy-paste executable HTML/JS and the Key APIs give concrete method calls, but Recipe #2 (React cleanup) is described conceptually rather than as executable code.

4 / 5

Workflow Clarity

The init/setOptions/resize/destroy lifecycle is clearly sequenced, but there are no explicit validation checkpoints; for this non-destructive simple skill that is a minor gap rather than a cap.

4 / 5

Progressive Disclosure

This is a simple, under-50-line skill with well-organized sections and no need for external bundle references (none exist), matching the simple-skill exception for a top score.

Description

87%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 strong, concise description with an explicit 'Use when' trigger and a clear, distinctive niche. Minor gains are possible by adding a few more natural synonyms and file/extension-style triggers.

DimensionReasoningScore

Specificity

The parenthetical '(setup, parameters, resizing, performance, integration in React/Next.js)' lists several concrete capability areas, but these are topics rather than the fully comprehensive set of distinct actions the score-5 anchor requires.

4 / 5

Completeness

It explicitly states what the skill does ('adding animated WebGL background effects with Vanta.js') and when to use it via a concrete 'Use when...' clause, satisfying the score-5 anchor.

5 / 5

Trigger Term Quality

Natural terms like 'animated WebGL background effects', 'Vanta.js', and 'React/Next.js' are present, but common synonyms such as 'hero background' or 'three.js background' are missing.

4 / 5

Distinctiveness Conflict Risk

The Vanta.js + animated WebGL background niche is highly specific with distinct triggers and minimal overlap risk with other skills.
