About

NeMo Relay observes and controls agent work at the boundary where it runs. Choose the path that matches the agent runtime, framework, or application you already use.

Choose Where Relay Attaches

Use the boundary that owns the model request or tool execution:

Agent runtime: Observe a coding agent without changing application code.
Framework: Use a maintained integration when the framework owns callbacks and tool execution.
Application: Instrument Python, Node.js, or Rust code when your application owns the tool or model call.

You do not need a Rust compiler, a source checkout, or repository development tools to install a published CLI binary.

Choose the shortest path for your runtime or application, then verify its output.

Install NVIDIA agent skills to give compatible coding agents product-specific Relay workflows and references. After the NeMo Relay skills are published in nvidia/skills, install the full Relay skill set without cloning the catalog:

npx skills add nvidia/skills \
  --skill nemo-relay-install \
  --skill nemo-relay-get-started \
  --skill nemo-relay-instrument-calls \
  --skill nemo-relay-instrument-context-isolation \
  --skill nemo-relay-instrument-typed-wrappers \
  --skill nemo-relay-plugin-observability \
  --skill nemo-relay-plugin-adaptive-tuning \
  --skill nemo-relay-plugin-build \
  --skill nemo-relay-migrate-from-flow \
  --skill nemo-relay-debug-runtime-integration \
  --agent codex

Use --agent claude-code, --agent cursor, or another supported agent target when that is where you want the skill installed. To inspect the current NVIDIA skill catalog first, run:

npx skills add nvidia/skills --list

Agent skills help your coding assistant apply Relay documentation and workflows. They do not replace installing NeMo Relay packages, configuring runtime plugins, or validating emitted events.

Go Beyond the First Run

After a working first run, choose an advanced path to build reusable behavior or operate Relay as a long-running service:

Build a Plugin

Create reusable behavior that observes or controls agent work.

Deploy a Daemon

Run Relay as a managed service for local users or remote clients.
