# Harness Integrations

> Connect NVIDIA NeMo Fabric to agent harnesses through adapters.

NVIDIA NeMo Fabric harness integrations are southbound: they connect NeMo
Fabric to agent harnesses through adapters that translate the normalized
contract into harness-native models, tools, sessions, and telemetry.

## Harness Integrations Maintained by NeMo Fabric

NeMo Fabric includes the following harness integrations:

| Agent Harness         | Guide                                                                                                          |
