What is alert thresholds?

Example: You have a morning planning agent — a routine that reviews your calendar, priorities, and energy level to produce a daily plan. Some days the plan misses a meeting or ranks a low-value task too high. That's normal variance. But when the plan misses meetings three days in a row, or when it consistently ignores your top priority for a week, something has changed. The difference between those two situations is a threshold. Without one defined in advance, you'll either shrug off a real problem or panic over routine noise.

This concept is part of Agent Monitoring in the How to Think curriculum.
