Asset Creator

Generate web page assets using the Gemini image generation API.

Arguments

• prompt: Description of the asset to generate (required)
• --aspect: Aspect ratio (default: 1:1). Options: 1:1, 16:9, 9:16, 4:3, 3:4
• --output: Output filename (default: auto-generated based on timestamp)

Instructions

When this skill is invoked, run the generation script with the user's arguments:

Copybash .claude/skills/asset-creator/scripts/generate-asset.sh [OPTIONS] "<prompt>"

Parsing Arguments

Parse the user's input to extract:

1. The --aspect option if provided (e.g., --aspect 16:9)
2. The --output option if provided (e.g., --output logo.png)
3. The remaining text as the prompt

Example Invocations

Copy# Simple icon generation
bash .claude/skills/asset-creator/scripts/generate-asset.sh "a minimalist coffee cup icon for a cafe website"

# With aspect ratio
bash .claude/skills/asset-creator/scripts/generate-asset.sh --aspect 16:9 "a hero illustration of a mountain landscape with sunrise"

# With custom output filename
bash .claude/skills/asset-creator/scripts/generate-asset.sh --output logo.png "a modern tech startup logo with abstract geometric shapes"

# With both options
bash .claude/skills/asset-creator/scripts/generate-asset.sh --aspect 4:3 --output banner.png "a promotional banner for a summer sale"

Prompt Enhancement

The script automatically enhances prompts based on detected asset types:

• Icons: Prepends "Create a simple, clean icon suitable for web UI. Use flat design with clear shapes."
• Logos: Prepends "Create a professional, modern logo suitable for web use. Ensure it works well at various sizes."
• Illustrations: Prepends "Create a modern, clean illustration suitable for a web page. Use a cohesive color palette."

Asset type is detected from keywords in the prompt (icon, logo, illustration, etc.).

Prerequisites

• Environment variable GEMINI_API_KEY must be set with a valid Gemini API key
• Required tools: curl, jq, base64

Error Handling

The script will report errors for:

• Missing GEMINI_API_KEY environment variable
• API errors from Gemini
• Missing image data in the response
• File save failures
