Generates minimal working code to test ideas before you commit to full implementation. Single file when possible, includes basic test data, skips polish and error handling to get you something runnable in minutes. Queries your preferred tech stack from memory, then builds the simplest version that validates the core concept. Best for proof of concepts and MVPs where you need visual feedback fast. The scope discipline is solid: happy path only, fake tokens instead of real auth, localStorage instead of a database. If you tend to over-engineer before validating assumptions, this forces the opposite habit. Ships with a README that lists exactly what's missing so you know what to add if the prototype proves the idea works.
