biomejs/biome — reverse-engineered prompt

Build me a fast code quality tool for modern web projects, kind of like an all in one cleaner for code. I want developers to be able to run it from the command line to format files, lint files, apply safe fixes, and do a stricter check for CI.

It should work well with JavaScript, TypeScript, JSX, JSON, CSS, and GraphQL. The formatter should feel familiar to people who use Prettier, and the linter should catch common problems with clear explanations, not just vague errors. Please make the messages helpful enough that someone can understand what is wrong and how to fix it.

I also want it to work nicely inside editors through language server support, so it can format and show issues while someone is typing, even if the code is currently broken. Use sensible defaults so people can start without a big config file. If you need current details for editor integration or CLI behavior, look up the docs online.
