Compose a structured, testable prompt using the shape that holds up in production, role, task, input, constraints, output format, and a fallback for when the task cannot be completed. Runs in your browser.

Who is the output for?

Output format

Fields or structure required

How to read this tool

It runs entirely in your browser and nothing you type is transmitted or stored. The output is indicative and derived from your own inputs, so it is only as good as they are. It is educational material, not professional, financial, legal or tax advice, and it is not an audit, a quote or a substitute for review by someone who can see your actual environment.
