Antigravity Gemini Image

Overview

Use the Gemini REST endpoint (via the local gateway base URL) to create or edit images. This skill wraps the correct request format for the gemini-3.1-flash-image model, which does not work reliably with /v1/responses + image_generation.

Quick start

Text → Image

mkdir -p ~/.openclaw/workspace/tmp
/usr/bin/python3 {baseDir}/scripts/generate_gemini_image.py \
  --prompt "A cute yellow chick mascot, vector style" \
  --out ~/.openclaw/workspace/tmp/chick.jpg

Image → Image (edit)

mkdir -p ~/.openclaw/workspace/tmp
/usr/bin/python3 {baseDir}/scripts/generate_gemini_image.py \
  --prompt "Add a tiny red scarf, keep the style" \
  --image /path/to/input.jpg \
  --out ~/.openclaw/workspace/tmp/chick_edit.jpg

Optional (explicit .env path):

/usr/bin/python3 {baseDir}/scripts/generate_gemini_image.py \
  --env-file ~/.openclaw/workspace/.env \
  --prompt "A cute yellow chick mascot, vector style" \
  --out ~/.openclaw/workspace/tmp/chick.jpg

macOS Keychain (optional): service openclaw-local-160, accounts base-url and api-key.

Workflow (always follow)

  1. Confirm the prompt (and optional input image) with the user.
  2. Run the script in scripts/generate_gemini_image.py.
  3. Return the generated image file to the user.

Parameters

  • --prompt (required): text instruction.
  • --image (optional): input image for edits.
  • --out (required): output path (jpg/png).
  • --env-file (optional): load a specific .env file.
  • --base-url (optional): defaults to LOCAL_160_BASE_URL.
  • --api-key (optional): defaults to LOCAL_160_API_KEY.
  • --model (optional): defaults to gemini-3.1-flash-image.
  • --temperature (optional): default 0.3.
  • --size (optional): default 4K (set via GEMINI_IMAGE_SIZE).
  • --ratio (optional): default 16:9 (set via GEMINI_IMAGE_RATIO).
  • --timeout (optional): HTTP 超时（秒），默认 1200（也可用 GEMINI_IMAGE_TIMEOUT 或 LOCAL_160_TIMEOUT）。

Notes

  • The gateway endpoint is: POST {BASE_URL}/v1beta/models/gemini-3.1-flash-image:generateContent
  • Auth header uses x-goog-api-key.
  • Image generation can be slow; 10–20 minutes is possible. Keep timeouts high (default 1200s or override via --timeout / env).
  • Output image is returned as base64 under: candidates[0].content.parts[*].inlineData.data.
  • 4K 输出必须写在 generationConfig.imageConfig（不要直接写 image_size）： 
    {"imageConfig": {"imageSize": "4K", "aspectRatio": "16:9"}}
