Content

65%

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

A richly detailed, project-specific skill with concrete named APIs, paths, and an executable validation command, but it is a long monolithic document whose prose could be tightened and whose import/publish workflows lack explicit validate-fix-retry feedback loops. Detail that could live in reference files is kept inline.

Suggestions

Tighten the wordy multi-line rules (material/palette and GLB-conversion sections) into terser directive bullets to improve token efficiency without losing the project-specific guidance.

Add an explicit validate→fix→retry feedback loop to the model-import and publish workflows (e.g., run the inline 'node --check' and confirm dist/ copy, then re-run on failure) to lift workflow clarity.

Offload the long material/palette and GLB-conversion detail into a reference file under references/ and link to it from the body, so SKILL.md reads as a tighter overview with one-level-deep navigation.

Dimension	Reasoning	Score
Conciseness	The body is dense with legitimately non-obvious project internals and avoids explaining concepts Claude already knows, but at ~205 lines several bullets are wordy prose (e.g., the multi-line material/palette and GLB-conversion rules) that could be tightened, fitting the score-2 'mostly efficient but could be tightened' anchor rather than the lean score-3 anchor.	2 / 3
Actionability	It gives concrete, specific guidance — exact paths ('engine/world/04-textures.js', 'vendor/three/tinyworld-three.r185.min.js'), named functions ('voxelAppearanceMaterial()', 'makeVoxelLiftEngine', 'twSetTextureSRGB(texture)'), and an executable validation command ('perl -0ne ... \| node --check') — meeting the score-3 bar for specific, actionable instruction-style guidance per the code_vs_instruction scoring note; it is not the vague score-1 or incomplete score-2 case.	3 / 3
Workflow Clarity	The 'Model import hygiene' section has an explicit numbered sequence (Box3/center/scale/shadows/tag/dispose) and a validation checklist, but there is no validate→fix→retry feedback loop around the import or publish flow, and most other sections are unsequenced rule lists, fitting the score-2 'steps listed but validation gaps' anchor rather than the score-3 anchor with explicit error-recovery checkpoints.	2 / 3
Progressive Disclosure	The file has clear section headers (good organization) but is a single monolithic ~205-line document with inline detail (material/palette and GLB-conversion rules) that could be offloaded to reference files, and no bundle files exist; this matches the score-2 'content that should be separate is inline' anchor rather than the score-3 'one-level-deep references' 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, well-scoped trigger description that clearly states both capabilities and an explicit 'Use when' clause tied to the Tiny World Builder niche. It is concrete, third-person, and unlikely to conflict with other skills.

Dimension	Reasoning	Score
Specificity	The description enumerates multiple concrete actions ('adding, importing, designing, reviewing, or animating') and concrete subjects ('Three.js procedural meshes, GLB/GLTF assets, Poly Pizza models, material palettes'), matching the score-3 anchor for listing several specific actions; it is not merely naming a domain like the score-2 anchor.	3 / 3
Completeness	It explicitly answers both 'what' (the enumerated asset types and operations) and 'when' via the explicit 'Use when adding, importing, designing, reviewing, or animating...' trigger clause, matching the score-3 anchor; it is not the score-2 case where 'when' is only implied.	3 / 3
Trigger Term Quality	It surfaces natural terms a user would say ('low-poly / stylized 3D assets', 'importing', 'animating', 'GLB/GLTF', 'clouds/planes/crop dusters') with broad coverage; the score-3 anchor rewards good coverage of natural terms, and while some entries lean technical (Poly Pizza, silhouettes), the common phrasings users would voice are present.	3 / 3
Distinctiveness Conflict Risk	It is scoped tightly to 'Tiny World Builder' with a distinct low-poly stylized-3D niche, making it unlikely to trigger for unrelated skills, matching the score-3 'clear niche with distinct triggers' anchor rather than the overlapping score-2 anchor.	3 / 3
