Generate prompts for AI coding assistants that carry the context and constraints they need (stack, conventions, boundaries, and what done means) rather than a one-line ask.
Describe what you want to build and get an optimized, structured prompt tailored for your favorite AI coding tool. Works entirely in your browser, no API calls.

Vibe coding works well right up to the point where it does not, and the failure is predictable. The generated code works, nobody understands it, and the first bug takes longer to fix than writing it would have taken. The difference between a prompt that produces maintainable code and one that produces a working black box is almost entirely context: naming conventions, error-handling patterns, which libraries are already in the project, what the surrounding code looks like.
The constraint that pays off most is asking for the smallest change that satisfies the requirement. Left unconstrained, assistants add abstraction layers, configuration options, and error handling for cases that cannot occur, and every one of those is code somebody has to maintain.
