What This Skill Does

rey-nano-banana is an advanced image generation agent skill powered by the Nano Banana Pro (Gemini 3 Pro) engine. Designed for creators, marketers, and developers, this skill bridges the gap between complex text-to-image prompts and high-quality visual outputs. Unlike generic image generators, it is specifically optimized for rendering Japanese text accurately within images, making it an essential tool for social media content, UI design prototypes, and localized marketing materials. It supports various artistic styles ranging from minimalist Scandinavian to vibrant cyberpunk aesthetics.

Installation

To add this skill to your OpenClaw ecosystem, execute the following command in your terminal:

clawhub install openclaw/skills/skills/sa9saq/rey-nano-banana

Ensure you have obtained a valid GOOGLE_AI_API_KEY from Google AI Studio. Set this key within your Cloudflare Workers environment variables to authorize the skill to communicate with the Gemini API. Without this key, the image generation requests will fail.

Use Cases

• Social Media Marketing: Create eye-catching posts for platforms like X, Instagram, or Facebook with native Japanese text overlays.
• Content Localization: Quickly generate localized assets where the text is baked directly into the visual style.
• Rapid Prototyping: Visualize UI concepts or mood boards using specific descriptive prompts.
• Creative Design: Develop stylized illustrations, ranging from soft watercolor sketches to complex cyberpunk concept art, using predefined style templates.

Example Prompts

1. "Generate a cozy watercolor illustration of a coffee shop scene with a soft orange and warm brown color palette. The Japanese text 「至福のひととき」 should appear at the bottom in a casual white handwritten font."
2. "Create a cute anime-style illustration of a robot holding a cat. Use a pastel blue gradient background. Include the Japanese text 「未来の友達」 at the bottom in a rounded font with a pink semi-transparent banner."
3. "Design a minimalist Scandinavian style graphic featuring a single line art of a mountain range on a beige background. Place the Japanese text 「絶景」 in a thin elegant black font at the bottom center."

Tips & Limitations

To achieve the best results with Japanese text, always enclose your text in 「」 brackets and explicitly define the font, color, position, and background banner properties. Avoid lengthy sentences for text overlays; keep them under 10 characters for optimal rendering accuracy. While the skill supports 2K and 4K resolutions, be mindful of your API quota. If the text rendering fails, ensure you are strictly following the 'Successful Pattern' defined in the documentation, as the model relies on structural consistency to interpret typographic instructions correctly.
