🎯 In one sentence: The way you phrase your request to Claude matters enormously. A good prompt gets you a great answer on the first try. A bad prompt wastes your messages.
A prompt is just whatever you type into the chat box. That's it. But the difference between a lazy prompt and a thoughtful one is the difference between a mediocre answer and an excellent one.
| ❌ Bad prompt | ✅ Good prompt |
|---|---|
| "Write me a blog post" | "Write a 600-word blog post about the benefits of cold showers for a health and fitness audience. Use a casual, conversational tone. Include 3 specific scientific benefits with brief explanations." |
| "Help me with my code" | "I have a React component that should fetch user data from /api/users and display it in a table. The fetch works but the table doesn't re-render when data arrives. Here's my code: [paste code]" |
| "Make this better" | "Rewrite this paragraph to be more concise. Keep the same meaning but cut it down to 2 sentences max." |
The more context you give, the better the output. Tell Claude the what, who it's for, how long, what tone, and what format.
| ❌ Don't do this | ✅ Do this instead |
|---|---|
| "Don't use bullet points" | "Write in flowing prose paragraphs" |
| "Don't be too technical" | "Explain this so a 15-year-old would understand" |
| "Don't make it too long" | "Keep your response under 200 words" |
Claude responds better to positive instructions. Telling it what you want gives it a target; telling it what you don't want just gives it a minefield.
If you want a specific style or format, show Claude an example. This is one of the most powerful techniques:
Write product descriptions for these items. Here's an example of the style I want:
Product: Wireless Earbuds
Description: Crisp sound, zero wires. These lightweight earbuds deliver studio-quality audio with 8 hours of battery life. Perfect for commutes, workouts, and everything in between.
Now write descriptions for:
1. Smart Water Bottle
2. Laptop Stand
3. Desk Lamp
Giving 2–3 examples dramatically improves consistency and quality.
This is Claude's superpower that most people don't know about. When your prompt has multiple parts, wrap them in XML tags:
<context>
I'm a freelance designer pitching to a SaaS startup.
They make project management software for agencies.
</context>
<task>
Write a cold email introducing my services.
Keep it under 150 words.
</task>
<tone>
Confident but not pushy. Professional but human.
</tone>
XML tags tell Claude exactly where each piece of information starts and ends. No ambiguity.
