I Built a $10K App With One Claude Fable 5 Prompt

I built a $10,000 app with one Claude Fable 5 prompt.
No code. No dev team. No babysitting the AI.
Here's the exact workflow, step by step ↓
This works for any app you've been putting off.
A client portal. A booking tool. An internal dashboard.
The flow is the same every time.
But first, here's why one-prompt builds never worked before:
→ You hand AI a task, then go check what it broke
→ It stops at 80% asking for a pat on the head
→ It guesses through every detail you didn't specify
→ It says "done" without ever testing a thing
Fable 5 killed all four.
I tested it for 24 hours on my own money to make sure.
Here's how to run it yourself:
𝐒𝐭𝐞𝐩 𝟏 → Open Claude Code, load Fable 5, set effort to extra high.
This is the mode built for long runs. Don't skip it.
𝐒𝐭𝐞𝐩 𝟐 → Don't describe your app. Make Claude interview YOU.
Tell it: "You're my technical co-founder. Interview me about the features, the data, and the design, one batch at a time. No code until I say go."
𝐒𝐭𝐞𝐩 𝟑 → Answer its menus. Real checkboxes, right in the terminal.
Let it push back. Mine talked me OUT of features so the build wouldn't balloon. That's it managing scope for you.
𝐒𝐭𝐞𝐩 𝟒 → When it hands back the full spec, type /goal and paste that spec in.
You never write the build prompt. The interview already wrote it for you.
𝐒𝐭𝐞𝐩 𝟓 → Walk away. Seriously.
It runs until the spec is real, then tests its own work end to end before it says done.
I ran this exact flow on a scheduling hub for my service business.
23 minutes. 119k tokens. One turn. A finished tool agencies quote five figures for.
It even flagged its own weak spot before I could.
That used to be my job.
The truth is the build is no longer the hard part.
If you can describe what you want, you can ship software now.
That's the whole skill.
This is the exact method I used to build the internal tool my team runs on now.
If you want to build your own, I documented the whole build, plus every other Fable 5 use case I tested.
