Nanobanana Image Generation

Generate high-quality images using nanobanana MCP with Gemini Imagen.

Core Principle

"Describe the scene, don't just list keywords."

Use narrative, descriptive paragraphs with rich context and specific details.


Prompt Workflow

1. Clarify Requirements

Use AskUserQuestion to gather:

  • Purpose: website, social media, product, illustration
  • Style: photorealistic, illustrated, stylized, minimalist
  • Elements: subject, composition, colors, mood, lighting
  • Specs: aspect ratio, background (transparent/solid)
  • Text: exact wording, font style (if applicable)

2. Select Strategy

| Use Case | Strategy | Reference | |----------|----------|-----------| | Marketing photos | Photorealistic | references/strategies.md | | Icons, stickers | Stylized | references/strategies.md | | Logos, posters | Text Rendering | references/strategies.md | | E-commerce | Product Mockups | references/strategies.md | | Banners | Minimalist | references/strategies.md | | Comics | Sequential Art | references/strategies.md |

3. Craft Prompt

Apply these principles:

  • Hyper-specificity: Detail trumps brevity
  • Context: Explain intended purpose
  • Semantic positivity: Describe what you want, not what to avoid
  • Cinematic language: Use photography/artistic terminology
