GPS for building with AI
Flows turns a build goal into a guided route: the exact prompt for each step, a strict Verify Gate before you move on, and a recovery prompt for when the AI fakes it.
Implement the real signup logic for this app. Do not only create a visual form. The signup flow must actually create a user record, validate input, handle duplicate emails, show loading states, show error states, and redirect the user after successful signup. Requirements: email and password fields; confirm password field; required field validation; email format validation; password minimum length validation; duplicate email handling; loading state while submitting; success state after account creation; error state for failed signup; store user profile data; redirect successful signup to the dashboard; keep the user session active after signup; make the form responsive on mobile. Also create or update any required backend routes, database schema, client state, and protected route logic needed to make this real.

More than a prompt library
Every flow is a route: an ordered chain of prompts with the context the AI needs. No guessing what to paste next.
Each step ends in a strict checklist. If a check fails, you do not continue. Fake progress gets caught immediately.
When the AI fakes UI or breaks something that worked, paste the recovery prompt and get back on route.
Recommended paths
Each path is a sequence of flows that build on each other.
For builders shipping an app end to end — every feature verified, nothing faked.
For apps that look finished but are fake underneath — convert visuals into real logic.
For builds that are done and need users — copy, press, launch, and outreach in order.
