What This Skill Does

The Nano Banana Pro skill acts as a powerful interface for the grsai.com API, enabling users to generate, modify, and iterate on high-quality images directly through the OpenClaw AI agent. Whether you need to create a brand-new visual asset from a text description or refine an existing image through an edit-based workflow, this tool provides granular control over the creative process. It supports multiple resolution tiers, ranging from 1K for rapid prototyping to 4K for production-ready deliverables, and handles aspect ratio adjustments to match your specific layout requirements.

Installation

To install this skill, run the following command in your terminal: clawhub install openclaw/skills/skills/delneg/nano-banana-pro-grsai Ensure you have uv installed, as the script relies on it for environment management, and ensure your GRSAI_API_KEY is configured in your system environment variables or passed during the execution phase.

Use Cases

• Creative Ideation: Quickly generate sketches and concept art at 1K resolution to visualize ideas before committing to high-fidelity renders.
• Image Refinement: Use the image-to-image capabilities to perform iterative edits, such as changing style, adding elements, or adjusting composition in existing assets.
• Asset Generation for Projects: Produce standardized 4K visuals for professional documents, websites, or marketing materials using specific aspect ratios.
• Bulk Rapid Prototyping: Streamline your workflow by programmatically generating multiple variations of an image with slight prompt tweaks to find the perfect output.

Example Prompts

1. "Generate a 4K, wide-angle cinematic shot of a cyberpunk city at night with neon lights and rainy streets, save it as city-render.png."
2. "Edit the image input.png to add a golden sunset background, keep the 16:9 aspect ratio, and save as sunset-version.png."
3. "Create a 2K resolution image of a minimalist wooden desk setup, use a 4:5 aspect ratio, and name the file desk-setup.png."

Tips & Limitations

• Iteration Strategy: Always start with 1K drafts to save time and API credits. Only switch to 4K once your prompt has been fine-tuned to your satisfaction.
• File Management: The script must be run from your current working directory. Do not manually change into the skill folder, or your generated files will be placed outside your active workspace.
• Moderation: Be mindful that prompts are subject to API content moderation. If a generation fails, try rephrasing your prompt to avoid sensitive topics.
• API Keys: If you do not want to provide the API key every time, add the GRSAI_API_KEY variable to your profile export file (e.g., .bashrc or .zshrc).
