Type your app idea. FirstThree scopes a tiny v1 (what to build, what to skip, the simplest stack) and writes three copy-paste prompts for Bolt, in build order.
Before the prompts you get the plan: 3 to 5 things v1 must do, what to skip (with a reason for each), the simplest stack for Bolt, and the main screens. Every prompt says what not to build yet and ends with a “Done when…” check.
Unedited FirstThree output for two one-sentence ideas.
