Banana Claude

AI image generation skill for Claude Code where Claude acts as Creative Director using Google's Gemini Nano Banana models.

Unlike simple API wrappers, Claude interprets your intent, selects domain expertise, constructs optimized prompts using Google's official 5-component formula, and orchestrates Gemini for the best possible results.

Quick Start

# Start Claude Code
claude

# Generate an image
/banana generate "a hero image for a coffee shop website"

# Edit an existing image
/banana edit ~/photo.png "remove the background"

# Multi-turn creative session
/banana chat

# Browse 2,500+ prompt database
/banana inspire

Claude will ask about your brand, select the right domain mode (Cinema, Product, Portrait, Editorial, UI, Logo, Landscape, Infographic, Abstract), construct a detailed prompt with lighting and composition, set the right aspect ratio, and generate.

Commands

How It Works

What Makes This Different

• Intent Analysis -- Understands what you actually need (blog header? app icon? product shot?)
• Domain Expertise -- Selects the right creative lens (Cinema, Product, Portrait, Editorial, UI, Logo, Landscape, Infographic, Abstract)
• 5-Component Prompt Formula -- Constructs prompts with Subject + Action + Location/Context + Composition + Style (includes lighting)
• Prompt Adaptation -- Translates patterns from a 2,500+ curated prompt database to Gemini's natural language format
• Post-Processing -- Crops, removes backgrounds, converts formats, resizes for platforms
• Batch Variations -- Generates N variations rotating different components
• Session Consistency -- Maintains character/style across multi-turn conversations
• 4K Resolution Output -- Up to 4096×4096 with imageSize control
• 14 Aspect Ratios -- Including ultra-wide 21:9 for cinematic compositions
