How to do it
- Write one paragraph: who it is for, the one job it does, and what "done" looks like.
- Ask the agent for a plan of 5 to 8 small steps before any code.
- Build one step at a time and click through the app after each.
- When something breaks, paste the exact error and what you clicked.
- Before sharing, ask for a security and privacy check.
The prompt
I want to build: {{app_idea}}.
It is for: {{audience}}. The one job it does: {{job}}. Done looks like: {{done}}.
Before writing code, give me a plan of 5 to 8 small steps, each one testable on its own. Ask me up to 3 questions if anything is unclear. Then build step 1 only and tell me exactly how to test it. Keep it simple: no login, payments or database until I ask for them.
