What does it mean that trigger sensitivity calibration?

Too sensitive and the agent fires too often — too insensitive and it never fires.

Example: You set a rule: 'Every time I feel frustrated, stop and journal.' Within a day you're journaling twenty times — after a slow elevator, a mistyped password, a lukewarm coffee. You abandon the practice within a week. The trigger wasn't wrong. Its sensitivity was miscalibrated. You needed 'frustrated for more than five minutes about something that affects my work' — a threshold that filters signal from noise.

Try this: Pick one trigger you currently use (or want to use) for a behavior change. Write down the last five times it fired. For each, mark whether the firing was a true positive (the situation genuinely warranted the behavior) or a false positive (the trigger fired but the behavior wasn't needed). If more than half are false positives, your threshold is too low — add a qualifying condition. If you can't remember five firings, your threshold may be too high — broaden the trigger condition and test for a week.
