SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires google-genai, and includes scripts (resource) components.

What problem does it solve?

This Skill enables high-quality image generation by translating natural language requests into optimized prompts for Nano Banana Pro (Gemini 3 Pro Image). It reduces guesswork and manual tuning, saving you time and ensuring text renders perfectly in output.

Core Features & Use Cases

  • Prompt enhancement: Converts natural language requests into modular prompts with subject, environment, text, style, and technical parameters.
  • Pattern detection: Detects infographic, typographic, portrait, or general image patterns to tailor prompts for consistent results.
  • Use Case: Quickly generate posters, logos, or diagrams from plain descriptions without iterative prompting.

Quick Start

Run the image generator with an enhanced prompt, e.g.: python ~/.claude/skills/nanobanana/scripts/generate.py "Render the text 'OPEN' on a neon sign in front of a city skyline with retro typography and photorealistic lighting"
