Think of a construction site where every subcontractor gets a blueprint, their own fenced-off area, and an inspector who checks the work before it joins the building. That's manager-mode: my open-source framework for running many AI coding agents at once without them stepping on each other or cutting corners. This page is the inspection record from one real build: 13 pieces, all passed, none torn out, $29.62 in AI cost. Faster delivery, and every step is on the record.
