# run-investigation-prioritization

`station__microgram__run-investigation-prioritization` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Transbeyesian class propagation → EIG priority ranking. For a drug-event signal, determines whether to investigate directly or rely on propagated evidence from structurally similar drugs in the same class.

> **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.

## Input schema

- `source_prr` *number* (required) — PRR value for the source drug-event pair
- `signal_threshold` *number* (required) — PRR threshold for signal detection (typically 2.0)
- `transfer_weight` *string* (required) — Structural similarity class: same_class | high | moderate | low | none
- `prior_strength` *string* (required) — Prior evidence strength: strong | moderate | weak | unknown
- `uncertainty_level` *string* (required) — Current uncertainty: very_high | high | moderate | low
- `extremity_level` *string* (required) — Signal extremity: extreme | moderate | low
- `propagation_count` *integer* (required) — Number of adjacent drugs in the class network that would benefit from this investigation
