ChatGPT Cheatsheet - AI Prompt Reference
The gap between a vague ask and a usable result is usually a prompt-structure gap. This reference organizes role setting, task scaffolding, output constraints, few-shot examples and chain-of-thought into patterns you can reuse, mapped to office, coding and writing workflows. Unlike a raw idea dump, each pattern tells the model who to be, what format to return, and how far to reason. After reading you steer output by adding structure instead of by trial and error.

Tips
- More specific prompts get higher-quality answers; avoid vague requests like 'write me something'.
- Use 'Don't...' to explicitly exclude unwanted content; it works better than only stating 'what you want'.
- Break long tasks into multiple turns, each focused on one subtask, better than cramming all needs at once.
- Giving examples (Few-shot) constrains output format better than description, especially for structured output.
- Asking to 'think step by step' improves accuracy on complex reasoning (chain of thought).
- Ask the model to restate your need before answering to reduce misunderstanding.
