  "title": "Prune noisy alerts before adding another one",
  "summary": "More warnings can make the important warning harder to hear.",
  "kind": "principle",
  "body": "Treat attention as a limited system resource. Measure which alerts are actionable, duplicated, stale or routinely dismissed; then remove, combine, delay or downgrade the low-value ones before adding more. Review the misses as well as the volume: a quiet channel that hides critical states is not an improvement. The goal is higher signal value, not simply fewer messages.",
  "limits": [
    "Do not optimize only for low alert count. Rare high-consequence alerts may deserve strong interruption even if they are inconvenient."

      "role": "supports",
      "note": "The cited evidence is clinical; notification fatigue in software can share the attention mechanism without having the same risk magnitude.",
      "locator": "Summary"
    },
    {
      "claim": "AHRQ's alarm-safety summaries emphasize reducing nonactionable alarms and improving the usefulness and prioritization of alerts rather than simply adding more alerts.",
      "source_id": "RS-A6ED4054F9E4F86D",
      "role": "supports",
      "note": "The correct alert threshold and modality depend on the task, consequence and user environment.",

  "use_when": [
    "People ignore, mute or delay responses to a notification channel that contains many false, duplicate or low-value alerts."

  "avoid_when": [
    "Do not optimize only for low alert count. Rare high-consequence alerts may deserve strong interruption even if they are inconvenient."
  ],
  "example": "If a CI channel posts every successful retry and every transient warning, group the routine noise and preserve immediate interruption for states that need human intervention.",
  "check": "The alert set becomes smaller or better grouped while retaining a clear path for genuinely time-sensitive states.",
