3d-four-seasons

Add coordinated spring, summer, fall, and winter states to a 3D scene, blending foliage, sunlight, sky, ground materials, snow, and particles without rebuilding the world. Use for seasonal controls, architectural walkthroughs, and outdoor scenes with four-season transitions.

Quality

Content

88%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 lean, technically dense, and well-sequenced with a concrete validation section, and its core mechanisms are given as executable code. The main weakness is a broken reference to a missing REFERENCES.md file and some advice-only sections lacking runnable examples.

Suggestions

Provide the referenced REFERENCES.md file (or remove the link) so the one-level-deep navigation actually resolves.

Add a short runnable snippet for foliage thinning (e.g., a deterministic threshold/dither example) to match the concreteness of the blend and snow code.

Tighten the accessibility and lighting-independence directives into a compact checklist so they read as actionable steps rather than prose advice.

Dimension	Reasoning	Score
Conciseness	The body is dense and assumes Claude's competence — referencing world-space geometric normals, smoothstep, program cache keys, and shader chunks without explaining basics — and every section earns its tokens with concrete guidance rather than padding.	5 / 5
Actionability	Two executable blocks (the four-component blend state machine with setSeason/stepSeason and the snow shader formula) cover the core mechanism, but sizable sections on foliage thinning, lighting independence, and accessibility are directive advice rather than runnable code.	4 / 5
Workflow Clarity	Sections proceed from authoring identity through sharing state, foliage/snow, responsiveness, to a "Verify" section that lists explicit checkpoints (recognizable without labels, drift/stale-shadow/allocation checks, snow exposure, desktop/mobile) — a clear sequence with validation and a feedback loop.	5 / 5
Progressive Disclosure	Content is well-organized into clear sections and keeps a single clearly signaled one-level reference ("Read [REFERENCES.md]"), but that referenced file is not present in the bundle, leaving a broken navigation link as a minor gap.	4 / 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 specific, complete, and distinctive, clearly stating both capability and trigger conditions in third person with concrete visual elements. Its only gap is trigger-term breadth, where a few natural synonyms would round out coverage.

Dimension	Reasoning	Score
Specificity	Names multiple concrete actions — "Add coordinated spring, summer, fall, and winter states" and "blending foliage, sunlight, sky, ground materials, snow, and particles without rebuilding the world" — giving comprehensive, specific coverage rather than vague domain language.	5 / 5
Completeness	It explicitly states both what (add and blend coordinated seasonal visual states) and when ("Use for seasonal controls, architectural walkthroughs, and outdoor scenes with four-season transitions") with concrete trigger phrases.	5 / 5
Trigger Term Quality	"Use for seasonal controls, architectural walkthroughs, and outdoor scenes with four-season transitions" supplies natural phrases, but common synonyms (weather, autumn, seasons) and any file-type triggers are absent, so it stops short of comprehensive coverage.	4 / 5
Distinctiveness Conflict Risk	The four-season 3D-scene framing — "coordinated spring, summer, fall, and winter states" on a 3D scene without rebuilding the world — carves a clear niche with distinct triggers and minimal overlap with other skills.	5 / 5
