# run-threshold-drift-detector

`station__microgram__run-threshold-drift-detector` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Detect threshold drift from consecutive warnings/criticals and declining reality trend. Outputs drift severity (NONE/MILD/SIGNIFICANT) with recommended action.

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
