Prompt Engineering Basics

Prompt engineering sounds like a job title. It’s mostly just: be specific about what you want.

Here are the principles that actually move the needle.

The four elements of a good prompt

1. Role — who should the AI be?
2. Task — what exactly do you want?
3. Context — what should it know?
4. Format — how should it respond?

You don’t need all four every time. But thinking through each one before you write your prompt will make it dramatically more effective.

Example: before and after

Before (vague):

Write a summary of this article.

After (specific):

Act as a copy editor. Summarize this article in 5 bullet points for 
a busy executive who won't read the full piece. Focus on decisions 
or actions implied by the content.

[article text]

The second version specifies role, task, context, and format. The output will be more useful on the first try.

The most important principle: iterate

Treat the first response as a starting point. Say what you’d change, and ask again:

• “Make this more concise.”
• “The tone is too formal — loosen it up.”
• “Add a specific example to point 3.”

Good prompting is a conversation, not a one-shot command.

When you’re stuck

If you’re not getting what you want, try one of these:

• Add a format constraint: “Answer in 3 bullet points” or “Respond in 2 sentences”
• Specify the audience: “Explain this to someone with no technical background”
• Ask for options: “Give me 3 different versions of this”
• Ask it to ask you: “What questions do you need answered to write the best version of this?”

The last one is underrated. Claude will tell you exactly what context it needs.
