threejs-image-generator

Generate and edit 2D image assets for Three.js games using Google's Gemini image API. Use for concept sheets, image-to-3D inputs, texture references, sky/background plates, decals, logos, icons, GUI art, title/menu art, thumbnails, marketing stills, and source images that feed threejs-3d-generator. Also use for direct image editing when the user provides an image path.

Quality

Content

100%Weight 40%Scale 1-3

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

A tight, actionable skill body that pairs executable commands and ready-made prompt patterns with clear sequencing and validation gates, all organized around a single real bundled script. It earns top marks across conciseness, actionability, workflow clarity, and disclosure.

DimensionReasoningScore

Conciseness

Lean, assumes Claude's competence, and avoids explaining known concepts; sections like 'Resolution mapping' and prompt patterns earn their tokens without padding. A couple of probe-retry notes are slightly long but stay within the lean anchor.

3 / 3

Actionability

Provides fully executable commands (uv run generate_image.py with --prompt/--filename/--resolution, --input-image for edits) and copy-paste prompt patterns; the referenced script is a real bundle file, so guidance is concrete and runnable.

3 / 3

Workflow Clarity

Sequences probe-key → generate → save → integrate → report with explicit checkpoints ('Verify how the image appears in game, not only that the file exists') and a gated skip rule ('MISSING is only a valid skip...when this output is shown'), giving a feedback loop for the risky credential step.

3 / 3

Progressive Disclosure

Body is organized into focused sections with a single one-level-deep bundle script referenced inline; no nested reference chains and no monolithic wall, fitting the well-organized-with-bundle-structure guideline.

Description

100%Weight 40%Scale 1-3

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, third-person description that names concrete capabilities, supplies explicit 'Use for' triggers with natural keywords, and is tightly scoped to its Three.js/Gemini niche. It cleanly satisfies all four dimensions.

DimensionReasoningScore

Specificity

States concrete actions ('Generate and edit 2D image assets') and enumerates a comprehensive list of asset types ('concept sheets, image-to-3D inputs, texture references, sky/background plates, decals, logos, icons, GUI art, title/menu art'), matching the multiple-specific-actions anchor.

3 / 3

Completeness

Explicitly answers what ('Generate and edit 2D image assets...using Google's Gemini image API') and when ('Use for...', 'Also use for direct image editing when the user provides an image path'), satisfying both halves.

3 / 3

Trigger Term Quality

Natural terms users would say ('Three.js games', 'texture references', 'decals', 'logos', 'icons', 'image editing', 'image path') give broad coverage rather than just 'some relevant keywords'.

3 / 3

Distinctiveness Conflict Risk

Scoped to Three.js game 2D assets feeding threejs-3d-generator via the Gemini image API, a clear niche unlikely to trigger competing skills.
