Hire an engineer that already knows your codebase — and can't merge without your say-so.
It works from a living map of your system — how it fits together and what's load-bearing — builds the change, tries to break its own work, opens the real screen to look, and still won't merge until you say go.

Four green seals. The agent still can't open it. You can.
It starts like a senior who's already worked here for years.
Before it touches a line, it knows how your product actually works — your flows, your house conventions, what's business-critical, and the corners where bugs love to hide. So it writes code that fits your system, not generic code.

Payments must never break — so that's where it reviewed hardest.
↓ same change, now under reviewThe diff was green. The screen was broken. It saw it.
A code review reads the diff. This opens the rendered screen and looks — catching the clipped button or broken layout a diff, by definition, can't.
.btn { + padding: 12px 28px; + white-space: nowrap; } // 6 files changed · tests green
Flip it yourself — the button is clipped. The diff never showed that; the screen did.

Four checks, then you. Broken work gets held and kicked back for a fix — it never reaches your branch on autopilot, and nothing merges without your approval.
A brief in. One reviewed PR out.
On your key, capped, with the whole trail — and the merge still yours.

The same run, role by role. Press a role to explore it.
Before it writes a line, it works from your company brain.
It plans from a living map of how your product actually works — your flows, your house conventions, what must never break, the corners where bugs love to hide. So every plan starts from your system, not a generic guess.
It builds the change in an isolated branch — and writes the test that proves it.
No cowboy commits. It works on an isolated working branch, in your existing style, and ships a test that proves the thing actually works — not just code that looks plausible at a glance.
A second, skeptical mind reviews the work — and actually looks at the screen.
It re-reads the change against the original brief, trying to break it. Then it opens the real, rendered page and sees it with its own eyes — catching the clipped button or broken layout that a code review, by definition, never can.
It refuses to take "tests pass" on faith.
Instead of trusting a green checkmark, it re-derives what should be true from the plan, runs your suite plus those fresh checks, and flat-out blocks the PR if anything's red. Green has to mean green.
It ships a real, clickable preview of the change.
A live preview URL spins up for the branch, so you — or your whole team — can click the actual change in a browser before anyone decides to merge. No "trust me, it works."
The one thing it will never do is merge without you.
Everything above runs on your own key, with a hard spend cap, and a full audit trail of every decision. The agents do the work; the last word is always a human's — nothing merges without your approval.
An engineer that does the work — and a merge button only you can press.
