`station__molecular-biology__nmd-check` · external (needs EXECUTION_BACKEND_URL configured) · domain `molecular-biology` · pv-relevance `pv-adjacent`

the filtered verdict, actions, and learning events.

> **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.
