3d-falling-leaves

Build recognizable falling leaves in world space using instanced geometry, independent tumble, coupled sideways drift, shared wind, scene occlusion, and camera-aware recycling. Use for 3D autumn leaves or drifting foliage in Three.js and similar scenes; use falling-leaves for a 2D canvas overlay.

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.

A dense, well-structured technical skill with concrete guidance and a verify step, weakened mainly by a referenced REFERENCES.md file that does not exist in the bundle.

Suggestions

Add the missing REFERENCES.md (or place it under references/) so the 'Read [REFERENCES.md]' link resolves, or remove the reference.

Include one or two more executable snippets (e.g. the InstancedMesh setup or the smoothstep fade) to raise actionability from mostly-executable to copy-paste ready.

Add an explicit feedback loop in the Verify section (what to fix if a check fails) to turn the observation checklist into a validate→fix→retry workflow.

DimensionReasoningScore

Conciseness

Lean and technical throughout, assuming Three.js competence; it gives constraints and formulas rather than explaining what a library or concept is.

5 / 5

Actionability

Provides an executable JS snippet for tumble/drift coupling and concrete formulas (e.g. the smoothstep fade), but most guidance is architectural with only one code block, leaving minor gaps.

4 / 5

Workflow Clarity

Sequenced build phases (leaf → tumble/drift → instance/recycle → integrate) with an explicit Verify checklist, but there is no validate→fix→retry feedback loop for error recovery.

4 / 5

Progressive Disclosure

The body is well-sectioned, but it directs the reader to '[REFERENCES.md](REFERENCES.md)' which is not present in the references/ directory or anywhere in the bundle, leaving a dangling navigation link.

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.

A strong, specific description that covers what and when clearly and distinguishes itself from a sibling 2D skill. Trigger-term coverage is good but could add a few more synonyms.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — 'instanced geometry, independent tumble, coupled sideways drift, shared wind, scene occlusion, and camera-aware recycling' — giving comprehensive coverage of what the skill builds.

5 / 5

Completeness

Explicitly states both what it does ('Build recognizable falling leaves...') and when to use it ('Use for 3D autumn leaves or drifting foliage in Three.js and similar scenes').

5 / 5

Trigger Term Quality

Natural phrases like '3D autumn leaves', 'drifting foliage', and 'Three.js' appear, but a few common synonyms or file/extension cues are missing, so coverage is good rather than comprehensive.

4 / 5

Distinctiveness Conflict Risk

Clear niche (3D foliage in Three.js-like scenes) with explicit disambiguation ('use falling-leaves for a 2D canvas overlay'), minimizing conflict risk.
