Quality

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.

The body is a tight, well-structured three-phase workflow (Specify, Implement safely, Verify) that assumes Claude's competence and includes explicit verification. Its main weakness is actionability at the checklist level rather than concrete implementable patterns, and the Verify step lacks an explicit fix-retry loop.

Suggestions

Add one short concrete code snippet for the highest-value safety rule (e.g., an idempotent cleanup or object-pooling pattern) to lift actionability from checklist-level to executable.

Turn the Verify section into an explicit feedback loop: state what to do when a check fails (e.g., 'if frame time regresses, reduce particle cap and re-sample') to add a validate->fix->retry checkpoint.

Consider a one-line pointer to an optional references file for advanced shader/quality-tier recipes, keeping the overview lean while enabling deeper detail.

Dimension	Reasoning	Score
Conciseness	Extremely lean with no padding and no explanation of concepts Claude already knows (e.g., no "Three.js is a 3D library"); every line is a directive ("Pool short-lived objects", "Make cleanup idempotent"), so every token earns its place.	5 / 5
Actionability	Concrete, specific, enumerated guidance (an explicit list of effect properties to define and an explicit test matrix) that is actionable for an instruction-only skill, but it stays at the checklist/constraint level without a concrete implementable pattern (e.g., an example pooling or idempotent-cleanup snippet), leaving minor gaps.	4 / 5
Workflow Clarity	A clear three-phase sequence (Specify -> Implement safely -> Verify) with an explicit verification section listing what to test, but the Verify step describes checks without an explicit error-recovery feedback loop (validate -> fix -> retry), so a checkpoint detail is missing.	4 / 5
Progressive Disclosure	A self-contained skill under 50 lines with no external references and three well-organized sections, which the simple-skills scoring note permits to score 5 on progressive disclosure with just well-organized sections.	5 / 5

Description

92%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 a strong, concise trigger: it states a concrete capability and follows with an explicit "Use for" clause listing many natural game-VFX trigger terms. Its only gap is listing effect categories rather than user-verbatim synonyms (e.g., the "VFX" shorthand).

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete effect categories ("attacks, impacts, damage feedback, status effects, spell trails, particles, shaders, telegraphs, quality tiers, and reduced-motion alternatives") with comprehensive coverage of the Three.js game VFX domain, matching the anchor for several specific concrete actions.	5 / 5
Completeness	Explicitly answers "what" ("Create readable, performance-safe Three.js game visual effects") and "when" ("Use for attacks, impacts, damage feedback, ...") with concrete trigger phrases via an explicit "Use for" clause, matching the anchor for both what and when with concrete triggers.	5 / 5
Trigger Term Quality	Strong natural trigger terms ("attacks, impacts, spell trails, telegraphs, shaders, Three.js") that game developers would actually say, but it lists effect categories rather than verbatim user phrases and omits common synonyms like the "VFX" abbreviation, so a few natural variations are missing.	4 / 5
Distinctiveness Conflict Risk	A clear niche (Three.js game VFX) with distinct triggers (telegraphs, spell trails, quality tiers, reduced-motion) that are unlikely to fire for unrelated skills, giving minimal conflict risk.	5 / 5
	Total	19 / 20 Passed
