Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/laurigates/claude-plugins --skill generate-image
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads generate-image automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Generate images using Google's Nano Banana Pro (Gemini 3 Pro Image) model.

When to Use This Skill

Use this skill when...Use imagemagick-conversion instead when...
Producing a brand-new image from a text promptConverting, resizing, or compressing an existing image
Generating cinematic, product, or portrait artworkBuilding thumbnails or batch-processing many files
Mixing up to five reference images into a new renderApplying deterministic transforms (rotate, crop, format)
Use this skill when...Use mermaid-diagrams or d2-diagrams instead when...
The output is a photographic or illustrative imageThe output is a flowchart, sequence, or architecture diagram
Quality settings (1K/2K/4K) and aspect ratio matterDiagram-as-code rendering would be more maintainable

Parameters

Parse these from $ARGUMENTS. The prompt is the quoted string (or, if unquoted, every token before the first -- flag):

  • prompt (required): Image description. If $ARGUMENTS is empty, ask the user for one and stop.
  • --aspect: Aspect ratio (1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9) - default: 16:9
  • --resolution: Image resolution (1K, 2K, 4K) - default: 2K
  • --reference: Path to reference image (repeatable, max 5)
  • --output: Custom output path

Environment Requirements

Verify API key is set:

echo "API Key: ${GOOGLE_API_KEY:+SET}${GEMINI_API_KEY:+SET}"

If not set, get one from: https://aistudio.google.com/apikey

Usage Examples

/generate-image "A beautiful mountain landscape at sunset"
/generate-image "Product photo on white background" --aspect 1:1 --resolution 4K
/generate-image "Portrait photo" --aspect 3:4
/generate-image "Cinematic scene" --aspect 21:9
/generate-image "Similar style" --reference existing_image.png

Task Workflow

  1. Parse arguments from $ARGUMENTS (see Parameters):

    • Extract the prompt
    • Read --aspect (default 16:9), --resolution (default 2K), each --reference <path> (at most 5), and --output <path> if given

  2. Build and execute the command, substituting the parsed values for the <...> slots. Add one --reference <path> per reference image and --output <path> only when given:

    uv run python .claude/scripts/nano_banana_pro.py "<prompt>" \
  --aspect <ratio> \
  --resolution <size> \
  --reference <path>

  3. Report results:

    • Show path to generated image
    • Note any reference images used
    • Offer next steps (regenerate, different aspect, etc.)

Output

Default output: ./generated/image_YYYYMMDD_HHMMSS.png

Custom output with --output:

/generate-image "Scene" --output custom_name.png

Reference Images

Reference images help maintain consistency:

  • Use existing images as style references
  • Keep subjects consistent across generations
  • Match artistic styles

When using references, describe the relationship:

  • "Similar style to the reference"
  • "This person in a different setting"
  • "Same product, different angle"

Maximum 5 reference images per generation.

Error Handling

  • No API key: Set GOOGLE_API_KEY or GEMINI_API_KEY
  • Generation failed: Simplify prompt or reduce references
  • Rate limited: Wait and retry
