One process, six stages. Tested with Claude.
Watch an example session play out below, then see exactly what happens at each stage. Tested with Claude so far; other AI chats haven't been tested yet, and results will be posted as they come in. Want the 2-minute tour first? Watch the walkthrough.
Watch an example session.
This is what using Blueprint actually looks like: a normal conversation with your AI, except now it asks the right questions, pushes back, and catches problems before they ship.
Six stages, in order. Each one leaves a document behind.
Every document ends with a short summary. Paste it into a new chat, or a different AI tool, and it picks up exactly where you left off.
Every stage works the same way
- Open that stage's folder and its
prompt.md - Paste the prompt into your AI, with the summary from the last stage
- Answer its questions and save the document it gives you
Already built your app? Start at 0-existing-app. With the Engine, Claude does all three steps for you.
Interrogate the idea
1-interrogate/prompt.mdTough questions about your user, their current workaround and your scope. Ends with a verdict: build it, shrink it, test it first, or don't. You save IDEA.md.
Write the spec
2-spec/prompt.mdFeatures with testable checks, every screen, every piece of data, and who can never see what. You save SPEC.md.
Architect it
3-architect/prompt.mdThe stack, how data is protected, where secret keys live, and what it costs, in plain English too. You save ARCHITECTURE.md.
Design with a point of view
4-design/prompt.mdThree genuinely different looks, built on your brand if you have one. You pick, and it becomes rules. You save DESIGN.md.
Build in small slices
5-build/prompt.mdOne testable piece per session, with standing orders the AI reads every time. You save PLAN.md and AGENTS.md.
Pass the security gate
6-ship/prompt.mdChecks you can do without reading code, plus a full review, before real users and payments touch your app. You save SECURITY.md.
Your next app shouldn't fall apart at feature six.
Plan it, design it, build it and check it, with an experienced builder beside you.
