Quality

Content

63%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, domain-specific rule compendium with concrete symbols and a solid validation section, but it is verbose, lacks executable code examples, and keeps all content in a single inlined file with no progressive disclosure to supporting files.

Suggestions

Tighten the long run-on bullets (e.g., the terrain-variants, fence-enclosure, and tower-door bullets) into shorter imperative statements to improve token efficiency.

Split the 'Terrain Styling Options' and 'LandscapeEngine Mesh Mode' sections into a separate references file (e.g., references/terrain-styling.md) and link to it from SKILL.md so the overview stays lean.

Add one or two small executable code snippets (e.g., a sample setCell call or fence-extras object) to lift actionability from concrete-symbol references to copy-paste-ready examples.

Dimension	Reasoning	Score
Conciseness	The body assumes Claude's competence (uses internal symbols like terrainFloors, terrainRiseAt, addEnhancementBits without explaining them), but many bullets are long run-on sentences that could be tightened, placing it just below the efficient anchor.	3 / 5
Actionability	Concrete guidance is strong — specific constants (WATER_SURFACE_DROP = TOP_H, CASTLE_AUTO_PROMOTION = false), file paths, and data shapes ({ kind: 'fence', fenceSide: 'n\|e\|s\|w' }) — but lacks full copy-paste code blocks, sitting between executable and fully copy-paste ready.	4 / 5
Workflow Clarity	A dedicated "Validation:" section lists explicit post-change checks for the risky batch/generated operations, supplying most checkpoints; the body is rule-based rather than a strict numbered sequence, so it stops short of the top anchor.	4 / 5
Progressive Disclosure	No bundle files exist (references/, scripts/, assets/ all absent) and everything is inlined in one ~120-line file with section headers; the terrain-styling and LandscapeEngine-mode sections read like content that could be split into separate reference files, and references are to repo paths rather than clearly signaled skill-bundle navigation.	3 / 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.

A strong, specific, third-person description with an explicit "Use when" trigger and concrete domain terms. It clearly signals both capability and invocation context with low conflict risk.

Dimension	Reasoning	Score
Specificity	The description lists multiple concrete capability areas — "repeat-click behavior, terrain stacking, floors/intensity, fences, rocks, walls, crops, or Monument Valley-like height/detail growth" — giving comprehensive coverage of the skill's domain rather than vague abstractions.	5 / 5
Completeness	It explicitly answers both what (adding/changing the listed tile/object behaviors) and when ("Use when adding or changing...") with concrete trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	Natural domain terms like "fences, rocks, walls, crops, terrain, Monument Valley-like" are things a user would plausibly say, but coverage leans on niche jargon with a few common synonyms missing, sitting just below the comprehensive anchor.	4 / 5
Distinctiveness Conflict Risk	The niche is tightly scoped to Tiny World Builder tile/object variation with very specific triggers, making conflict with unrelated skills minimal.	5 / 5
	Total	19 / 20 Passed
