catalan-adobe/gemini-icon-set
Generate production-quality colorful icon sets using Google Imagen 4. Use this skill when the user needs custom app icons, emoji-style icons, cartoon icons, or any colorful icon set. Takes a project description, suggests icons, generates 1024px PNGs via Imagen 4, removes backgrounds, downscales to all target sizes, and delivers a review gallery for iterative refinement. Trigger on: "icon set", "generate icons", "app icons", "custom icons", "colorful icons", "cartoon icons", "emoji icons", "make icons", "icon generation", "imagen icons", or any request for a set of colorful visual assets.

Quality
Discovery
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.
This is an excellent skill description that clearly articulates specific capabilities (icon generation, background removal, downscaling, review gallery), provides explicit trigger guidance with a comprehensive list of natural user terms, and occupies a distinct niche. It uses proper third-person voice throughout and balances detail with conciseness.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: suggests icons, generates 1024px PNGs via Imagen 4, removes backgrounds, downscales to target sizes, and delivers a review gallery for iterative refinement. | 3 / 3 |
Completeness | Clearly answers both 'what' (generate production-quality icon sets, remove backgrounds, downscale, deliver review gallery) and 'when' (explicit 'Use this skill when...' clause plus a detailed 'Trigger on:' list). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms including 'icon set', 'generate icons', 'app icons', 'custom icons', 'colorful icons', 'cartoon icons', 'emoji icons', 'make icons', and 'icon generation' — these are terms users would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive — targets a specific niche of colorful icon set generation using Google Imagen 4, with clear triggers that are unlikely to conflict with general image generation or design skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured, highly actionable skill with a clear iterative workflow and explicit validation checkpoints via gallery review. Its main weakness is moderate verbosity—the script-locating fallback block, standalone installation section, and some explanatory notes could be trimmed or moved to reference files. Overall it's a strong skill that would guide Claude effectively through the icon generation pipeline.
Suggestions
Move the script-locating fallback logic and standalone installation section to a separate SETUP.md reference file to reduce the main skill's token footprint.
Move the style presets table into references/STYLES.md (which already exists) and just reference it from the main skill, keeping only a brief mention of available presets.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient but includes some unnecessary content like the standalone installation section, verbose script-locating fallback logic, and explanations of what rembg/sips do that Claude would already know. The pipeline overview duplicates the step-by-step content below it. | 2 / 3 |
Actionability | Provides fully executable bash commands, concrete JSON manifest format, specific file paths, exact command sequences, and clear examples of output. The iteration workflow with specific rm commands and re-run sequences is copy-paste ready. | 3 / 3 |
Workflow Clarity | The multi-step pipeline is clearly sequenced (Steps 0-7) with explicit validation via gallery review, a well-defined feedback loop (Steps 5-6 repeat until satisfied), and clear instructions for each review outcome (keep/retry/drop/add). The retry workflow includes specific file deletion and regeneration steps. | 3 / 3 |
Progressive Disclosure | There is one reference to an external file (references/STYLES.md) which is good, but the main SKILL.md is quite long with detailed inline content that could be split out (e.g., the script-locating fallback logic, the detailed process/gallery command descriptions, standalone installation). The style presets table could live in the styles reference. | 2 / 3 |
