nano-banana-pro-openrouter
Generate images with Nano Banana Pro via OpenRouter. Use when the user asks for image generation, mentions Nano Banana Pro, Gemini 3 Pro Image, or OpenRouter image generation.
Why use this skill?
Use the Nano Banana Pro skill to generate high-quality AI images directly within OpenClaw. Features include resolution scaling, auto-saving, and API integration.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/duffycoder/nano-banana-pro-openrouterWhat This Skill Does
The nano-banana-pro-openrouter skill provides OpenClaw users with a direct interface to leverage Nano Banana Pro (Gemini 3 Pro Image Preview) via the OpenRouter API. This skill enables the generation of high-quality images based on natural language prompts. It manages the entire lifecycle of an image request, from initial draft generation to final high-resolution rendering, ensuring that users can iterate efficiently without wasting resources. By utilizing standard shell scripts, the skill interacts with OpenRouter's infrastructure to produce visual assets that are automatically saved in the designated local workspace for easy retrieval.
Installation
To install this skill, use the OpenClaw management command: clawhub install openclaw/skills/skills/duffycoder/nano-banana-pro-openrouter. Ensure that your environment is properly configured with your OpenRouter credentials. If you have an .env file, the skill will read it to automatically handle the OPENROUTER_API_KEY and OPENROUTER_BASE_URL. If not, be prepared to provide your API key during execution.
Use Cases
This skill is designed for creative professionals, developers prototyping user interfaces, and anyone needing quick, AI-generated visual content. Typical use cases include:
- Generating conceptual sketches for design projects.
- Creating assets for web or mobile applications.
- Rapidly iterating on artistic visions using the draft-to-final workflow.
- Testing the capabilities of the Gemini 3 Pro Image model.
Example Prompts
- "Generate a 1K image of a futuristic cyberpunk city at sunset for a draft design."
- "I need a high-res, 4K version of the previous cat portrait using Nano Banana Pro."
- "Can you create a medium resolution image of a tranquil mountain lake with pine trees?"
Tips & Limitations
To optimize your usage, always adhere to the draft-iterate-final workflow. Start with 1K resolution for prompt testing to save on costs and time. Only upgrade to 2K or 4K when you are satisfied with the composition. Note that this skill is currently limited to generating new images; editing or in-painting existing images is not supported. Ensure you are using the absolute path when calling the script, as relative pathing from other directories will cause the skill to fail. Always rely on the --filename auto flag for organized, timestamped file management.
