Pydantic parameter models for tau2_telecom DB shapes.

Used primarily by scripts/prepare_tau2_data/prepare_telecom.py to round-trip the upstream TOML files through Pydantic — this materializes default field values (e.g. UserSurroundings.signal_strength per-network defaults, MockPhoneAttributes field defaults) that aren’t present in the raw TOML. After round-trip the converted JSON is shape-complete and downstream predicate / init function code can read fields via dict access without defensive .get(..., default) everywhere.

Per-tool *Params argument-schema classes are added incrementally as each LLM-callable tool is ported (same pattern as tau2_airline_params.py / tau2_retail_params.py).

str
class nemo_voice_agent.evaluation.tools.tau2_telecom_params.SetApnSettingsParams()

class nemo_voice_agent.evaluation.tools.tau2_telecom_params.SetNetworkModePreferenceParams()

mode is the string value of a NetworkModePreference enum (e.g. "4g_5g_preferred", "4g_only", "3g_only", "2g_only"). Invalid values are rejected by the tool with a failure message instead of a Pydantic ValidationError, so the schema accepts a plain str — matches upstream’s permissive signature.

Database interface for the telecom domain (agent-facing).

Database interface for the telecom domain (user-facing).

Round-trip target for scripts/prepare_tau2_data/prepare_telecom.py’s user_db.toml → user_db.json conversion. Critical to materialize the default surroundings block so predicate / init functions can read its fields without dict-key-missing errors.

str
class nemo_voice_agent.evaluation.tools.tau2_telecom_params.UserSurroundings()

Bases: BaseModelNoExtra

Physical surroundings of the user (per-task; populated by init actions).

Per-task user state — name, phone number, location, signal-strength table at the user’s current location, etc. Upstream’s user_db.toml only carries the device defaults; surroundings is populated per-task by initialization_actions like set_user_info and set_user_location. The Pydantic round-trip in prepare_telecom.py materializes the default surroundings block (with name=None, phone_number=None, is_abroad=False, etc.) so init functions can mutate fields without needing defensive .setdefault().
