A Client Just Handed You a Vibe-Coded App. Here's How to Scope It in Minutes.

When a client shows up with an app that's "80% done" but breaking, the slow part isn't fixing it — it's figuring out what "it" even is.

A Code→PRD audit reads the client's existing code and hands you a clean spec in minutes, so you can scope, quote, and hand off to your devs without burning days reverse-engineering a black box.

Why do so many client projects now arrive half-built?​

Because roughly 60% of new code shipping in 2026 was written by a model. Clients no longer come with a napkin sketch — they come with a Cursor or Bolt project that got most of the way there and then started falling over.

For agencies, vibe coding has quietly become a procurement category: businesses actively look for shops that can take AI-generated code and make it survive real traffic. That's the opportunity. It's also the trap — because the hardest part of these projects isn't the build, it's the scoping.

Why is scoping a vibe-coded app so painful?​

A half-built AI app is a black box for you, too. There's no spec, no documentation, and often a client who can't explain what the code does because they prompted their way to it. So your team faces the worst kind of estimate:

  • Days of reverse-engineering before anyone can even quote the job — unbillable time that kills your margin.
  • Client miscommunication, because you're both guessing at what the app is supposed to do versus what it actually does.
  • Risk you can't see, since 40–62% of AI-generated code ships with security flaws you'll inherit the moment you touch it.

How does Code→PRD change the math?​

Instead of assigning an engineer to spelunk through the repo, you run a Code→PRD audit on the client's app. It reconstructs the product definition — features, data model, architecture — as a readable spec. In minutes, you get:

  1. A clean scope. You see exactly what exists, what's broken, and what's missing — so your estimate is grounded in reality, not guesswork.
  2. An accurate quote. Refactor-and-stabilize work for AI-generated apps commonly starts around $4K; now you can price it with confidence instead of padding for the unknown.
  3. A clean hand-off. Your developers start from a documented spec, not a mystery repo — the fastest path to shipping in production.

Code→PRD is a speed multiplier for your team, not a replacement for it. Your edge is scoping and architecting the last mile — the audit just removes the days of unpaid discovery so your devs go straight to high-value work.

Doesn't this replace my developers?​

No — it makes them faster and your quotes tighter. The best shops already ship production apps in 6–8 weeks at 10–20x traditional velocity by building AI-first. A spec at the front of that pipeline means your engineers spend their time on architecture and the client's hardest problems, not on decoding what the last tool left behind.

FAQ​

How long does a Code→PRD audit take on a client project? Minutes to read the repo and produce a first spec — versus the days an engineer would spend reverse-engineering it manually. You can scope on the same call.

Can I use this to give clients a fixed quote? That's the point. Once you can see the real state of the code, you can price the refactor-and-stabilize work accurately instead of hedging against the unknown.

Will this compete with the developers I already have? No. It hands your team a documented starting point so they skip discovery and go straight to building — a multiplier on the work they already do best.
