Mid-level interview question
What goes wrong if the harness just drops the oldest messages when the context fills?
Model answer
The oldest message is often the task itself. FIFO assumes early messages matter least, and the book warns that can be fatally wrong, especially when they state the purpose.
In the course's 12-step run, dropping the oldest loses the task at step 6 while the context still looks fine.
