About#

Use this section when you want the nemo-flow binary to observe local coding agent sessions through hooks, a passthrough LLM gateway, and NeMo Flow observability exporters.

The NeMo Flow CLI is installed by the nemo-flow-cli Cargo package. It can run supported coding agents through a managed local gateway, forward agent hook payloads into NeMo Flow lifecycle events, route OpenAI-compatible or Anthropic-compatible model traffic through the gateway, and diagnose local configuration.

Start Here When#

Use these guides when you need to:

  • Observe Claude Code, Codex, Cursor, or Hermes Agent sessions locally.

  • Configure coding-agent hooks for NeMo Flow lifecycle events.

  • Route model-provider traffic through the local NeMo Flow gateway.

  • Export local sessions to Agent Trajectory Interchange Format (ATIF), Agent Trajectory Observability Format (ATOF) JSONL, OpenTelemetry, or OpenInference.

  • Diagnose hook loading, gateway routing, and exporter output.

If you are instrumenting an application or framework directly, use Instrument Applications or Integrate into Frameworks instead.

Agent Harness Support#

NeMo Flow CLI support is experimental and observability-focused.

Notes

Claude Code

✅ Yes

❌ No

❌ No

Observability only; no known issues.

Codex

✅ Yes

❌ No

❌ No

Observability only; some hooks needed for full feature coverage are missing.

Hermes Agent

✅ Yes

❌ No

❌ No

Observability only; no known issues.

Cursor

✅ Yes

❌ No

❌ No

Observability only; missing hooks under cursor-agent limit feature coverage.

Guides#

Use these guide links to move from CLI setup into agent-specific instructions.

  • Basic Usage explains gateway routes, transparent runs, shared configuration, hook forwarding, and runtime mapping.

  • Claude Code covers transparent Claude Code runs, Anthropic gateway routing, ATIF verification, and unsupported Claude application modes.

  • Codex covers transparent Codex CLI runs, local GUI/app caveats, model provider routing, and remote-task limits.

  • Cursor covers transparent Cursor runs, temporary hook patching, GUI and CLI smoke tests, and gateway routing limits.

  • Hermes Agent covers Hermes shell hook installation, dynamic gateway URL handling, session-finalize behavior, and hook consent caveats.

Start with Basic Usage, then use the guide for the coding agent that you want to observe.
