`station__algovigilance__microgram-calculate-compute-expectedness` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Assess whether an adverse event is expected (listed) or unexpected (unlisted) based on reference safety information. Unexpected serious events require expedited reporting.

## Agent metadata

- `idempotent`: true
- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
- `cost_tokens_estimate`: unknown

## Input schema

- `event_term` *string* (required) — MedDRA preferred term for the adverse event
- `drug_name` *string* (required) — Drug name to check against
- `reference_source` *string* — Reference: SmPC, USPI, IB, or CCDS
