Field notes
The main exercise stages inventory events that arrive out of order, with duplicate messages and expired reservations contributing to a ghost order. Users direct an agent in natural language, inspect its code changes, and run public tests; the page lists 29 cases and says a model key must be supplied by the user. Its simulation library is explicitly different: those exercises use example source and preset agent replies, without real model calls or actual fixes.
