Grok Image Generation

Generate new images and edit existing images with xAI Grok Imagine from a local OpenClaw workspace. Use when the user wants Grok/xAI as the image source for prompt-based image generation, batch variations, reference-image edits, style transfer, cleanup, background replacement, product art, poster concepts, or reusable local automation around xAI image APIs.

Use the local scripts in this skill when the user specifically wants Grok/xAI for image generation or editing.

Quick workflow

1. Confirm XAI_API_KEY exists in the local environment.
2. For new images, run scripts/grok_imagine.py generate ....
3. For edits or variations from source images, run scripts/grok_imagine.py edit ... with one to three --image or --image-url inputs.
4. Save outputs under a task-specific folder when the user names a destination; otherwise use the default output/grok-images/.
5. If prompts are weak or generic, read references/prompt-templates.md and improve them before generating.

Commands

Run from the skill directory or give absolute paths.

Generate

powershell

py -3 scripts\grok_imagine.py generate "A retro sci-fi poster with a giant moon" --aspect-ratio 2:3 --resolution 2k --n 1

Batch variations

powershell

py -3 scripts\grok_imagine.py generate "A clean premium mockup of a horror-movie T-shirt design" --n 4 --aspect-ratio 1:1

Edit one source image

powershell

py -3 scripts\grok_imagine.py edit "Turn this into a vintage pulp-poster illustration" --image C:\path\to\source.png --resolution 2k

Combine multiple references

powershell

py -3 scripts\grok_imagine.py edit "Place the subject from image one into the lighting and palette of image two" --image C:\path\subject.png --image C:\path\style.png

Prompting rules

• State what must be preserved before what must change.
• For products and mockups, prioritize subject accuracy and readability.
• For T-shirt art, ask for strong silhouette, high contrast, and print-friendly detail.
• For batches, request meaningful variation in composition, angle, and lighting.
• For edits, keep the instruction narrow unless the user wants radical transformation.

Read references/prompt-templates.md when you need a starting prompt pattern.

Editing and variations

Treat variation in three ways depending on the job:

• Same prompt, multiple fresh outputs -> use generate with --n > 1
• Same image, changed style or cleanup -> use edit with one source image
• Composite / transfer / merge references -> use edit with two or three source images

Failure handling

• If xAI returns 403 mentioning credits, licenses, or permissions, stop and tell the user billing/access is the blocker.
• If returned image URLs are temporary, download them immediately; the script already does this.
• If xAI changes payload shape, update scripts/grok_imagine.py using references/api-reference.md plus the latest xAI docs.
