NVIDIA NeMo Fabric Adapter Contract
nemo-fabric-adapter-contract provides the typed Python configuration and
execution contract implemented by NeMo Fabric adapters. It does not include a
lifecycle host, harness integration, or NeMo Relay integration.
Python adapters use standard-library dataclasses backed by the version-matched
nemo-fabric-evidence package. Neither package requires third-party libraries. Adapters in other languages can consume the JSON
Schemas published by NeMo Fabric without a Python package dependency.
nemo_fabric_adapter_contract.evidence and .codec preserve their existing
imports by re-exporting shared types and validation from nemo_fabric_evidence.
The SDK consumes that shared package directly.
The dataclasses provide strict from_mapping() validation and JSON-compatible
to_mapping() serialization. Install the optional pydantic extra when an
adapter uses Pydantic models for typed extensions or wants Pydantic
interoperability. Both paths use the same contract dataclasses.
Import AgentConfig from the contract models module:
from nemo_fabric_adapter_contract.models import AgentConfig
NeMo Fabric delivers AgentConfig as the southbound configuration. Python
adapters using the optional common lifecycle host pass
AgentConfig.from_mapping as the config_loader.
Install
Install the package directly when developing a Python adapter:
pip install nemo-fabric-adapter-contract
Install the optional pydantic extra to enable Pydantic interoperability.
pip install "nemo-fabric-adapter-contract[pydantic]"
Use the maintained adapter contract documentation and canonical JSON Schemas as the implementation source of truth. Source code is available in the NVIDIA NeMo Fabric repository.
