What they do

Problem

Autonomous coding agents make too many unchecked decisions, causing engineers to lose ownership and creating hard-to-maintain production codebases.

Solution

A collaborative coding agent that asks for confirmation before acting, keeping developers in control while working on real codebases.

Who it's for

Software engineers and development teams building and maintaining production code.
