lightweight-3d-effects

Lightweight 3D effects for decorative elements and micro-interactions using Zdog, Vanta.js, and Vanilla-Tilt.js. Use this skill when adding pseudo-3D illustrations, animated backgrounds, parallax tilt effects, decorative 3D elements, or subtle depth effects without heavy frameworks. Triggers on tasks involving Zdog pseudo-3D, Vanta.js backgrounds, Vanilla-Tilt parallax, card tilt effects, hero section animations, or lightweight landing page visuals. Ideal for performance-focused designs.

Quality

Content

65%

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

The content is highly actionable with abundant working code, but it is an oversized monolith that duplicates material already present in unreferenced bundle files and explains concepts Claude already knows. Trim the inline prose and delegate API/effect detail to the existing reference files.

Suggestions

Replace the inlined library overviews, config-option tables, and the six full Vanta effect blocks with brief pointers to references/zdog_api.md, references/vantajs_effects.md, and references/tilt_patterns.md, keeping only a single quick-start example per library in SKILL.md.

Cut explanatory prose that restates what each library does ("Zdog is a pseudo-3D engine...", "Vanta.js provides animated WebGL backgrounds..."); assume Claude knows these libraries and keep only non-obvious gotchas like the hex-number-not-string color rule.

Add a short decision section that tells Claude when to pick Zdog vs Vanta vs Vanilla-Tilt (or how to combine them) with explicit checkpoints, rather than presenting three parallel tutorials.

Dimension	Reasoning	Score
Conciseness	The body is a long monolithic tutorial that restates concepts Claude already knows (e.g., "Zdog is a pseudo-3D engine...", "Vanilla-Tilt.js adds smooth 3D tilt effects...") and inlines large config-option dictionaries, so it is mostly useful but could be tightened and trimmed.	2 / 3
Actionability	It provides fully executable, copy-paste-ready code throughout—complete HTML setup files, exact CDN URLs, working Zdog/Vanta/Vanilla-Tilt snippets, and React integrations—matching the fully-executable anchor.	3 / 3
Workflow Clarity	Each library section sequences setup→shapes/effects→animation, and the Pitfalls sections offer problem→cause→solution loops, but there is no explicit validation checkpoint workflow and no crisp decision tree for choosing or combining the three libraries.	2 / 3
Progressive Disclosure	Real bundle files exist (references/zdog_api.md, vantajs_effects.md, tilt_patterns.md, plus scripts/ and assets/), but the body never references or links to any of them, inlining API detail, effect examples, and config tables that belong in those files—structured enough to avoid a 1, but disclosure is poorly signaled.	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.

The description is strong: it states concrete capabilities, provides explicit "Use when"/"Triggers on" guidance, and is clearly distinguishable from heavier 3D skills. It is concise yet complete.

Dimension	Reasoning	Score
Specificity	The description names multiple concrete outputs—"adding pseudo-3D illustrations, animated backgrounds, parallax tilt effects, decorative 3D elements, or subtle depth effects"—matching the anchor for listing several specific concrete actions, not just naming a domain.	3 / 3
Completeness	It explicitly states both what (lightweight 3D effects for decorative elements/micro-interactions using the three libraries) and when ("Use this skill when..." and "Triggers on..."), satisfying the what-and-when anchor with explicit trigger guidance.	3 / 3
Trigger Term Quality	It covers natural user terms and library names together—"Zdog pseudo-3D, Vanta.js backgrounds, Vanilla-Tilt parallax, card tilt effects, hero section animations, or lightweight landing page visuals"—giving good coverage of phrases users would actually say.	3 / 3
Distinctiveness Conflict Risk	The named lightweight libraries and "without heavy frameworks" carve a clear niche distinct from heavier 3D skills, with triggers unlikely to fire for the wrong skill.	3 / 3
	Total	12 / 12 Passed
