What this skill does
Nano Banana Antigravity (Gemini 3 Pro Image via OAuth) Generate images using Nano Banana Pro (Gemini 3 Pro Image) via your existing Google Antigravity OAuth credentials. No separate API key needed! Uses the same OAuth tokens as your OpenClaw Antigravity provider. Generate Image Generate with Options Edit/Composite Images Multi-image Composition Options --prompt, -p (required): Image description or edit instructions --filename, -f (required): Output filename --input-image, -i: Input image(s) for editing (can be repeated) --aspect-ratio, -a: 1:1 (default), 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9 --resolution, -r: 1K (default), 2K, 4K Authentication Uses existing OpenClaw Antigravity OAuth credentials. Make sure you're authenticated: The script looks for credentials in: ~/.openclaw/credentials/google-antigravity.json ~/.config/openclaw/credentials/google-antigravity.json ~/.config/opencode/antigravity-accounts.json Notes The script prints a MEDIA: line for OpenClaw to auto-attach on supported chat providers. Do not read the image back; report the saved path only. Uses timestamps in filenames for uniqueness: yyyy-mm-dd-hh-mm-ss-name.png Falls back to regular Nano Banana if Nano Banana Pro isn't available yet.
