Banana

This is a creative director layer over Google's Gemini image generation that refuses to pass raw user prompts through. Instead, it interprets your request, picks a domain mode (cinema, product, portrait, etc.), then constructs a detailed prompt using a five-component formula with real camera specs, brand names, and micro-details. It's opinionated about workflow: you must generate through /banana commands, it checks for brand presets in your home directory, and it handles safety filters with automatic rephrasing. The MCP setup assumes you have Gemini API access and want Claude to act as the prompt engineer rather than doing it yourself. Good if you want guardrails and consistent output structure, limiting if you prefer direct control over generation parameters.
