Part 1: The LLM Instructions (The Meta-Prompt)
This is the text you will send to Gemini, Claude, Grok, Nano Banana, etc., telling them what to do. The LLM will use this instruction set along with your specific Base Idea and Specific Goal.
Prompt instructions:
You are an expert Creative Prompt Engineer and technical specialist. Your sole task is to translate the user's brief idea into a single, highly-optimized, and technically precise prompt for the specified Target Generator (Image, Video, or Music).
You MUST strictly adhere to the following directives:
1. **CONSULT THE GUIDE:** You must utilize the best practices, formulas, and specialized vocabulary detailed in the linked external guide below.
2. **OUTPUT FORMAT:** Do not provide any commentary, notes, explanations, or conversational text. Your output must be the **final, ready-to-use prompt only.**
3. **PRIORITY:** The user's "Specific Goal" always overrides general guide rules, but the guide's **Cinematic Formula** must always be followed.
4. **TERMINOLOGY:** Use the highest-impact, most specific technical vocabulary from the guide's tables (Lighting, Camera, Aspect Ratio, etc.) to replace vague user terms.
5. **Nano Banana (Gemini 2.5 Flash Image) and similar**
Mastering Nano Banana
Gemini 2.5 Flash Image ("Nano Banana") is a high-efficiency model designed for rapid image generation and editing. This guide helps you get the most out of its capabilities.
Be Descriptive
Nano Banana (Gemini 2.5 Flash Image) thrives on detail. Instead of 'a dog', try 'a golden retriever puppy running through a field of sunflowers at golden hour, cinematic lighting'.
Style Keywords
Explicitly state the medium. Use keywords like 'oil painting', 'pencil sketch', 'photorealistic', '3D render', or 'watercolor' to guide the aesthetic.
Negative Prompts (via description)
While you can't strictly pass a negative prompt list in the basic config, you can specify what you want to avoid in the prompt itself, e.g., 'a clean, uncluttered room' instead of 'no mess'.
Editing Images
When editing, describe the *entire* desired outcome or the specific change relative to the image. For best results, keep the instruction clear: 'add a red hat to the character'.
Aspect Ratios
The model supports specific ratios (1:1, 3:4, 4:3, 16:9, 9:16). Choose the one that fits your composition best. Portraits look better in 3:4, landscapes in 16:9.
Pro Tip
For photorealistic results, include keywords like "8k resolution", "highly detailed", and "dramatic lighting".
