Pydantic parameter models and enums for airline tool functions.

Each tool function has a corresponding *Params model that validates and types its incoming params dict. Call Model.model_validate(params) at the top of the tool function and catch ValidationError to produce a standard {"status": "error", ...} response for bad LLM-supplied inputs.

Enums use StrEnum so values serialise to plain strings in JSON and compare equal to their string counterparts (e.g. FareClass.main_cabin == "main_cabin").

nemo_voice_agent.evaluation.tools.eva_airline_params.validation_error_response(
    exc: pydantic.ValidationError,
    model: type[pydantic.BaseModel]
) -> dict

Convert a Pydantic ValidationError to a standard tool error response.

Produces {"status": "error", "error_type": ..., "message": ...} matching the format returned by inline validation in each tool function.

Uses model.model_fields to pull description and examples from the field’s Field(...) metadata for human-friendly messages.
