Explanation
Prompt engineering means writing better instructions for AI. Context engineering means giving the AI the right background information. AI agents are systems that can perform tasks step by step.[1][2]
Prompt engineering
This is about how you ask the AI. Clear, specific prompts usually give better answers. For example, “Write a short email asking for a meeting” is better than “Write an email.”[3]
Context engineering
This is about what the AI knows before it answers. It may include chat history, documents, memory, or tools. Good context helps the AI give more useful and accurate answers.
AI agents
An AI agent is like a helper that can do more than chat. It can plan, use tools, and keep working on a task. For example, it can search, compare options, and make a summary.
Simple difference
- Prompt engineering =
how you ask. - Context engineering =
what you give it. - AI agents =
AI that can act.
Easy example
If you ask an AI to help plan a trip, that's prompt engineering.
Context engineering is your dates, budget, and preferences.
The AI agent uses both to suggest a trip plan.
