Claude Models Prompt Guide
Claude works best when you give it clarity, context, and structure. Here’s how.
Table of Contents
1. Be Explicit and Detailed
Claude doesn’t fill in the blanks. If your prompt is vague, you’ll get vague results. Clear, detailed instructions push Claude to deliver higher quality output.
Less effective:
Summarize this documentMore effective:
Summarize this 20-page market research report for executives. Keep the summary under 300 words, highlight 3 key insights, and avoid technical jargon. Format the output as bullet points for a slide deck.Tip: Add modifiers like “concise,” “detailed,” “executive-friendly,” or “slide-ready” to shape the result you want.
2. Add Context for Clarity
Claude works best when it knows why you need the result and who it’s for. Rules alone aren’t enough. Explain the purpose.
Less effective:
Never use ellipsesMore effective:
Your response will be read aloud by a text-to-speech system, so never use ellipses. The system cannot pronounce them and it will disrupt the flow.When possible, include:
Purpose (e.g., “internal research for Q4 planning”)
Audience (e.g., “executives with no technical background”)
Workflow (e.g., “feeds into a presentation deck”)
Success criteria (e.g., “summary under 300 words, free of jargon”)
3. Give Step-by-Step Instructions
Breaking tasks into steps helps Claude follow complex requests more reliably. Instead of bundling everything, spell it out.
Unclear prompt:
Summarize this 20-page reportClear prompt with steps:
Task: Summarize this 20-page market research report for executives.
Steps:
1. Identify the 3 most important insights
2. Remove all technical jargon and use plain language
3. Keep the entire summary under 300 words
4. Format the result as bullet points for a slide deck4. Use Claude’s “Thinking” Mode
Claude 4 can pause and reflect before giving its final output. This makes it especially strong for reviewing documents or complex reasoning.
Prompt idea:
After reading the report, reflect on the key themes before writing the summary. Double-check that the final version is clear, jargon-free, and under 300 words.This approach works well for:
Reviewing lengthy reports before drafting summaries
Iterating on a first draft for clarity
Comparing multiple sources and extracting common themes
5. Run Through a Quick Checklist
Before sending your prompt, ask yourself:
Did I specify the purpose, audience, workflow, and success criteria?
Did I clearly state what to include and what to avoid?
Did I break complex instructions into steps?
Did I add quality modifiers (“concise,” “executive-ready,” etc.)?
Do I want Claude to reflect before finalizing the output?
This five-second check can turn a weak summary into a strong one.
