Fulling

An agent that claims to act as a full-stack engineer invites scepticism, because the gap between a convincing demo and a maintainable feature is where most of these efforts fall down. To its credit, on a contained task it produced a working front end and a matching backend with reasonable structure, not just a screenshot. Where I want evidence is longevity: how the code holds up under a second and third change, whether it writes tests it then respects, and how it behaves when requirements contradict earlier ones. The foundation, built on a familiar stack, is legible enough to take over by hand, which matters more than the autonomy. Promising, and worth watching, with the usual caution about trusting it unsupervised.

A full-stack engineer agent built on Next.js and Claude is an ambitious claim, and on a small feature it actually delivered a coherent front and back end. It made sensible data choices. I would test it hard on error handling and edge cases before trusting a real ticket to it.

There is something uncanny about handing over a whole feature, front to back, and watching a believable version appear. It reads less like a tool and more like a junior who never sleeps. The work needs review, but the starting point it gives you is real.
