Question
How do I practice false negative rate?
Quick Answer
Pick one agent — a habit trigger, a review routine, a decision rule — that you trust to catch problems. Look back at the last 30 days. Identify at least two situations where that agent should have fired but didn't. Write them down. For each miss, note: what was the situation, what should the agent.
The most direct way to practice false negative rate is through a focused exercise: Pick one agent — a habit trigger, a review routine, a decision rule — that you trust to catch problems. Look back at the last 30 days. Identify at least two situations where that agent should have fired but didn't. Write them down. For each miss, note: what was the situation, what should the agent have caught, and why did it stay silent? This is your empirical false negative audit.
Common pitfall: Trusting silence. When an agent stops firing, you assume things are fine rather than asking whether the agent has gone blind. The most dangerous failure is the one you never learn about — not because it didn't happen, but because nothing in your system told you it did.
This practice connects to Phase 28 (Agent Monitoring) — building it as a repeatable habit compounds over time.
