How to Build Better AI Prompts

Great prompts are the foundation of effective AI agents. Use structured sections for Role, Task, Tone, and Constraints to get consistent, high-quality responses.

Prompt Engineering Best Practices

  • Define a clear role: Tell the AI who it is and what expertise it has
  • Be specific about the task: Clear instructions lead to better outputs
  • Set the tone: Match the communication style to your use case
  • Add constraints: Limitations help keep responses focused and relevant

Using Generated Prompts

Copy your generated prompt into any LLM (GPT-4, Claude, GLM-4) or use it with Whizo AI's agent runtime for autonomous task execution.
