How to write better Claude prompts, with examples
Last updated July 2026
A good Claude prompt gives four things: a role, the task, the context, and the output format. "Write something about our product" fails. "You are a B2B copywriter. Write a 5-line LinkedIn post announcing X to Y audience, in a plain, confident tone" works. Specificity is the whole game.
- 1
Give it a role
Start with who Claude should be ("You are a financial analyst"). It sets the vocabulary, depth, and assumptions.
- 2
State the task and the goal
Say exactly what you want and why, so Claude optimizes for the outcome, not just the words on the page.
- 3
Add the context
Paste the source material, the audience, the constraints, and an example of good output. Claude can only use what you give it.
- 4
Specify the format
Ask for the exact shape: 5 bullet points, a 3-column table, under 100 words, so you do not have to reformat afterward.
- 5
Iterate with precise edits
Refine with targeted instructions ("make it warmer", "cut the jargon") instead of rewriting the whole prompt.
- 6
Ask it to think, or to ask first
For hard tasks, tell Claude to reason step by step, or to ask you clarifying questions before it answers.
Quick tips
- Show one example of the output you want, it beats any description.
- Do not stuff keywords; clear instructions always win.
- Save the prompts that work and reuse them as templates.
Frequently asked questions
Why does Claude give me generic answers?
Almost always because the prompt is generic. Add a role, real context, and a target format, and the output changes completely.
How long should a Claude prompt be?
As long as it needs to carry the context and constraints, and no longer. A precise paragraph usually beats a one-line request.
Can I reuse prompts?
Yes, and you should. Save the ones that work as templates. Kognitaa's Vault is a library of ready-to-use Claude prompts, templates, and Skills.
