What makes a Claude prompt work
Use tags to separate the parts
Claude was trained to pay attention to XML-style tags. Wrapping your source material in <document> and your instructions in <instructions> reliably stops it from confusing the two — which matters enormously when you paste in something long.
Put the long material first, your question last
When you paste a big document, Claude does better if the document comes first and the actual question comes at the end. It is the opposite of how most people write a prompt, and it is one of the biggest free wins available.
Give it room to think
Claude is unusually good at working through a problem before answering. Saying "think it through in <thinking> tags first, then give your final answer" produces noticeably better reasoning on hard tasks — and you can just ignore the thinking section.
Be direct about tone
Claude leans careful and even-handed. If you want a blunt opinion, a firm recommendation, or a critical review, you have to ask for it explicitly — otherwise it will present you with a balanced set of considerations you did not want.
The same request, before and after
What people usually type
review this contract and tell me if it is bad
What actually gets a usable answer
<document> [paste the contract here] </document> <instructions> You are a commercial lawyer reviewing this on behalf of the supplier. Identify every clause that is unusually unfavourable to the supplier. For each one: quote it, explain the practical risk in one sentence, and suggest specific replacement wording. Think through the contract in <thinking> tags first. Then give me a direct verdict: would you sign this as-is? Yes or no, and why. Do not hedge. </instructions>
The tags stop Claude from treating the contract as instructions, and the closing line stops it from giving you a balanced overview when you wanted an answer.
Common questions
Is this Claude prompt generator free?
Yes. Generate prompts on this page with no account. The Chrome extension adds one-click prompting inside claude.ai itself.
Does this work with Claude Sonnet, Opus and Haiku?
Yes. The structure that works for one Claude model works across the family. Clear structure helps the smaller, faster models most.
Why does Claude need XML tags when ChatGPT does not?
It is a training difference, not a rule. Claude was trained with tagged inputs and follows them very reliably, which makes it much harder to accidentally confuse your data with your instructions.
