Quality

Content

77%

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

Highly actionable copy-paste code across a broad effect catalog with a clear setup/combine workflow, but the body is over-long and repetitive with no progressive disclosure via reference files. The main weaknesses are redundancy and a monolithic structure.

Suggestions

Show the EffectComposer + RenderPass import/setup once and reference it from later sections instead of repeating the same block in Quick Start, EffectComposer Setup, and Combining Multiple Effects.

Move the per-effect catalog (Bloom, SSAO, DOF, Halftone, etc.) into reference files (e.g. references/effects.md) and keep SKILL.md a concise overview with one-level-deep links, enabling progressive disclosure.

De-duplicate the bloom example, which currently appears in Quick Start, Common Effects, Combining Multiple Effects, and Performance Tips.

Dimension	Reasoning	Score
Conciseness	The ~600-line body is code-dense and largely free of conceptual padding, but the EffectComposer/RenderPass setup and bloom blocks are repeated across Quick Start, EffectComposer Setup, and Combining Multiple Effects — unnecessary duplication that could be tightened.	2 / 3
Actionability	Every effect is shown with complete, copy-paste-ready executable imports and constructor calls (e.g., UnrealBloomPass with annotated strength/radius/threshold), meeting the fully-executable anchor.	3 / 3
Workflow Clarity	The setup workflow (composer -> RenderPass -> add passes -> composer.render()) is unambiguous, and 'Combining Multiple Effects' provides a numbered 1-5 pass sequence with ordering notes; no destructive/batch validation is needed here.	3 / 3
Progressive Disclosure	No bundle files exist, so the entire 16-effect catalog is inline in a single monolithic document; the section headers give structure, but per-effect detail that could be split into references is all in SKILL.md, matching the 'content that should be separate is inline' anchor.	2 / 3

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 strong, third-person description that pairs specific capabilities with an explicit 'Use when' trigger clause covering natural user terms. It cleanly distinguishes the skill's niche with no vague fluff.

Dimension	Reasoning	Score
Specificity	Names multiple concrete capabilities — "EffectComposer, bloom, DOF, screen effects" — rather than vague language, matching the "lists multiple specific concrete actions" anchor.	3 / 3
Completeness	Explicitly answers both what ("EffectComposer, bloom, DOF, screen effects") and when ("Use when adding visual effects, color grading, blur, glow...") with an explicit trigger clause.	3 / 3
Trigger Term Quality	Covers natural user phrasings — "visual effects, color grading, blur, glow, or creating custom screen-space shaders" — giving good coverage of terms a user would actually say.	3 / 3
Distinctiveness Conflict Risk	The Three.js post-processing niche is clearly bounded with distinct triggers, making it unlikely to fire for unrelated skills.	3 / 3
