1. AI Image Generation Prompts (Midjourney, Gemini, ChatGPT Image Tools)
Good image prompts include subject, style, lighting, mood, and details like resolution.
- Futuristic City: "Futuristic cyberpunk city skyline at night, neon lights reflecting on wet streets, flying cars, holographic ads, cinematic lighting, ultra-detailed, 8K --ar 16:9 --v 6"
- Portrait: "Portrait of a young woman celebrating New Year 2026, fireworks in background, warm festive lighting, cinematic style, highly detailed, 8K"
- Fantasy: "Epic fantasy castle floating in clouds, glowing sunset, dragons flying, magical atmosphere, intricate details, cinematic 8K"
- Realistic: "Hyper-realistic portrait of a robot detective holding a rose, noir style, dramatic shadows, high detail, 4K"
- Abstract: "Abstract digital art with swirling colors, neon blue and pink, data streams and holograms, futuristic, clean vector style"

2. AI Coding Prompts for Developers
Use these in ChatGPT, Claude, or Gemini for better code output. Be specific about language, framework, and requirements.
- Refactor Code: "Refactor this JavaScript function to be more readable and efficient. Use modern ES6+ syntax, add comments, and handle edge cases: [paste your code here]"
- Build API: "Create a REST API in Python with FastAPI for user management. Include CRUD endpoints, validation with Pydantic, and error handling. Provide full code structure."
- Debug: "This code throws an error: [paste code and error]. Explain the issue step-by-step and provide a fixed version."
- Optimize: "Optimize this SQL query for better performance on large datasets. Explain your changes."
- Explain Concept: "Explain promise chaining in JavaScript with examples, then convert this callback code to async/await."
3. Prompt Engineering Tips & Examples (for ChatGPT/Claude/Gemini)
Best practices: Assign a role, provide context, use chain-of-thought, ask for step-by-step reasoning.
- Role Play: "You are an expert senior developer with 20 years experience. Review this code for security vulnerabilities, performance issues, and best practices."
- Chain of Thought: "Solve this problem step-by-step: [problem]. Think aloud before giving the final answer."
- Few-Shot: "Here are examples: Input1 -> Output1; Input2 -> Output2. Now process this: Input3"
- Structured Output: "Respond in JSON format with keys: summary, pros, cons, recommendation."
