What do you want?
A few details
It asks only what it can't safely assume, and lists what it assumed so you can change it.
Your Claude prompt
What you type is kept in this browser. It goes to the page's AI only when you press a button that writes, remixes or tests; the checks run in your browser. Each platform's rules come from its own guide, read on 2026-09-27.
This free Claude prompt generator writes to Anthropic's own best practices and checks every tag is closed.
Here's what Claude's own guide asks for, how the generator writes to it, and how to check a prompt before you use it.
What is a Claude prompt generator?
A Claude prompt generator is a tool that turns what you want into a complete Claude prompt, written to Anthropic's own best practices: clear and direct, with XML sections and examples in tags.
How to use the Claude prompt generator
What Claude's own guide asks for
The generator writes every prompt to these rules, read on 2026-09-27:
- Clear and direct, as if briefing a brilliant new colleague who has no context. If you want more than the minimum, ask for it outright.
- Give the reason behind each rule: Claude generalizes from the why ("read aloud by a text-to-speech engine, so no ellipses").
- 3 to 5 examples, relevant and varied, each in <example> tags inside <examples>, so they're never read as instructions.
- XML tags with consistent names separate the parts: <role>, <context>, <instructions>, <examples>, <input>, <output_format>.
- A one-line role at the top.
- Long documents go at the top, the question and instructions at the end (Anthropic measured up to 30% better answers).
- Say what to do instead of what not to do ("write in flowing paragraphs", not "no markdown"), and write the prompt in the style you want back.
- Current Claude models follow instructions literally and answer briefly: ask for a summary, detail or length explicitly.
- Format: XML-tagged sections.
- For agentic work (Claude Code, Cowork): state the quality bar and that it matters, grant the tools, tell it to work on its own until done, point it at what to read first, and cap any spend ("max spend is $10").

For Claude Code, Cowork and long runs
For agentic work, the prompt that people reran on their own projects this month worked for 4 reasons: it stated the quality bar and that it mattered, granted the tools, said to work until done, and capped the spend. The Claude Code prompt generator writes those for code.
Who is the Claude prompt generator for?
It's for anyone who uses AI every day and wants the first answer to be the right one:

- Post image generator – creators turning a prompt's words into a branded image
- Presentation generator – speakers who want the talk, not just the prompt
- Readability checker – anyone checking the answer reads plainly
- Lead magnet generator – coaches turning a good answer into a free guide
