技能说明

Nano Banana Pro Image Generation

Generate new images using OpenRouter's Nano Banana Pro (Gemini 3 Pro Image Preview).

Usage

Run the script using an absolute path (do NOT cd to the skill directory first):

Generate new image:

sh ~/.openclaw/workspace/skills/nano-banana-pro-openrouter/scripts/generate_image.sh --prompt "your image description" [--filename "output-name.png" | --filename auto] [--resolution 1K|2K|4K] [--api-key KEY]

Note: the shell version currently supports generation only (no input image editing).

Important:

Images are always saved under ~/.openclaw/workspace/outputs/nano-banana-pro-openrouter
If --filename contains a path, only the basename is used

Default Workflow (draft -> iterate -> final)

Goal: fast iteration without burning time on 4K until the prompt is correct.

Draft (1K): quick feedback loop
- sh ~/.openclaw/workspace/skills/nano-banana-pro-openrouter/scripts/generate_image.sh --prompt "<draft prompt>" --filename auto --resolution 1K
Iterate: adjust prompt in small diffs; keep filename new per run
Final (4K): only when prompt is locked
- sh ~/.openclaw/workspace/skills/nano-banana-pro-openrouter/scripts/generate_image.sh --prompt "<final prompt>" --filename auto --resolution 4K

Resolution Options

The Gemini 3 Pro Image API supports three resolutions (uppercase K required):

1K (default) - ~1024px resolution
2K - ~2048px resolution
4K - ~4096px resolution

Map user requests to API parameters:

No mention of resolution -> 1K
"low resolution", "1080", "1080p", "1K" -> 1K
"2K", "2048", "normal", "medium resolution" -> 2K
"high resolution", "high-res", "hi-res", "4K", "ultra" -> 4K

API Key and Base URL

The script checks for the API key in this order:

--api-key argument (use if user provided a key in chat)
OPENROUTER_API_KEY environment variable

The API base URL must be set via OPENROUTER_BASE_URL. Use the full chat completions endpoint (for OpenRouter: `https://openrout...

# Nano Banana Pro Image Generation

Generate new images using OpenRouter's Nano Banana Pro (Gemini 3 Pro Image Preview).

## Usage

Run the script using an absolute path (do NOT cd to the skill directory first):

```
Note: the shell version currently supports generation only (no input image editing).

Important:
- Images are always saved under `~/.openclaw/workspace/outputs/nano-banana-pro-openrouter`
- If `--filename` contains a path, only the basename is used

## Default Workflow (draft -> iterate -> final)

- Iterate: adjust prompt in small diffs; keep filename new per run
- Final (4K): only when prompt is locked
