| description | Generates images using OpenRouter. Triggers on /generate-image [prompt] [--model model-id] or automatically when an image is needed in context. |
generate-image Skill
Trigger Conditions
Invoke this skill when:
- User types
/generate-image [prompt] — optionally with --model [model-id]
- User says "generate an image of X", "create a picture of X", "draw X", "make a visual of X", "show me an image of X"
- The task clearly requires a visual asset (logo, banner, illustration, diagram, etc.)
How to Execute
The generate-image script path was provided at session start (see [image-generator] Tool script ready in session context).
Use the Bash tool to call it directly:
node "<script-path-from-session-context>" "<prompt>" [--model <model-id>] [--output-dir <dir>]
The script handles everything: API call, response parsing, base64 decode, file save.
It prints Image saved: <path> on success or a clear error message on failure.
Examples
node "/path/to/scripts/generate.js" "a sunset over mountains"
node "/path/to/scripts/generate.js" "a minimalist cat logo" --model google/imagen-4.0-generate-001
node "/path/to/scripts/generate.js" "abstract art" --output-dir ./assets
After the script runs
Report to the user:
- The saved file path
- The model used
- Optionally, offer to open or display the image
Model Reference
All models use OpenRouter's /api/v1/chat/completions endpoint — no special routing needed.
