Working, tested code. Reviewed twice before you ever say ship.
Build is where the approved architecture becomes production-ready code. Written by specialized agents, put through automated tests, reviewed by a second AI agent for the failures unchecked AI code is famous for, and then reviewed by you.
Construction, with the plans already approved.
By the time Build starts, there's nothing left to guess. The PRD says what, the design says how it looks, the Blueprint says how it's engineered. The build agents implement against all three, in tested increments, with Neo tracking every decision against what you already approved. Deviations get flagged, not buried.
Software you can launch, and everything behind it.
Production-ready code
Not a prototype that falls over the moment someone other than you uses it.
A test suite that ran
Automated tests written and passing, covering the failures that only show up under real use.
A double review
A second AI agent reviews for security and quality before you ever see it. Then you review.
Full ownership
Source code, tests, and documentation, handed over clean. Your product, your repo, no lock-in.
Everything from all four stages ships together: PRD, designs, architecture, code. One coherent handover.
Roughly half of AI-generated code fails on security. Ours gets reviewed like it matters.
That failure rate is why AI code review is built into the stage, not offered as an add-on. A second agent reviews every increment for security and quality, tests run before you're asked to look, and nothing ships until you say ship. The four-stage process exists because unchecked AI code doesn't hold up. Checked code does.
You say ship. Then it ships. Not the other way around.
Frequently asked questions
Production-ready code is software built to survive real users: tested, secure, documented, and structured to be maintained and extended. It's the difference between a demo that works when you drive it and a product that works when strangers do. Build is the NeoCrew stage that produces it.
Every increment of code is reviewed twice before shipping: first by a second AI agent checking for security flaws, quality issues, and deviations from the approved architecture, then by you at the final gate. This double review exists because roughly half of unchecked AI-generated code ships with an exploitable flaw.
Yes. Automated tests are written alongside the code and run before your review, covering the failure modes that only appear under real use. You're shown what passed, what Neo thinks of the build, and whether anything deserves a closer look.
Yes, all of it. Source code, tests, architecture documentation, designs, and the PRD hand over together in standard formats. Your product, your repository, no lock-in.
You own everything needed to run and extend the product, with any team. And because Neo keeps what the project taught it, your next build on NeoCrew starts from your preferences and patterns instead of from zero.
The last stage, and the only one most tools start with.
Tell us what you're building. It'll be planned, designed, and architected before this stage ever runs. That's the point.
