A ROS 2 support guide for checking whether a usable ROS 2 Jazzy environment is present and for planning related deployment specifications. ROS 2 is software used to connect and coordinate components in robot systems; the listed bridge, bag conversion, and fleet adapter features are not implemented.

Use it to run the ROS 2 Jazzy prerequisite check or create deployment plans for bridge, bag, and Open-RMF fleet work without executing ROS 2 code.

It prevents a local or container-only check from being mistaken for proof that a remote robot is ready. It also makes clear which operations are real and which are only planning outputs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.00684
Opus 5.5	$0.00017	$0.00274
Sonnet 5.5	$0.00009	$0.00137

Security

Grade A, and why

ros2 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ROS 2

ROS 2 is the robotics middleware tool for prerequisite detection and deployment planning.

The toolRef intentionally exposes only what is real: the preflight command detects whether a usable ROS 2 Jazzy environment is present (ros2 CLI on PATH, ROS_DISTRO exactly jazzy, rclpy importable) and fails fast with a remediation message when it is not. Bridge (bag/MCAP <-> topics), bag conversion, and the Open-RMF fleet adapter are not implemented and are not exposed. Deployment planning (stage specs, Jetson Thor target) lives in the pipeline module, which emits specs without executing ROS 2 code.

Preflight measures the environment of its own process. Direct CLI use measures the machine where it runs; a workflow measures its task container. Select an image with ROS 2 Jazzy installed and sourced through the workflow resource image or image override. There is no built-in ROS 2 image route, and the default CPU image will report missing prerequisites. This tool never probes a remote robot host or certifies that host from a pod-local result.

Interfaces

CLI: npa workbench ros2 preflight --help
Python SDK (workbench-first): npa.workbench.ros2 (preflight)
Workflow module: npa.workflows.byof.ros2_pipeline (stage specs, Jetson Thor deploy target, argparse entrypoint)
Catalog toolRef: workbench.ros2.preflight (python3 -m npa.workflows.byof.ros2_pipeline --preflight)

Conventions

The CLI lives at npa.cli.workbench.ros2 (multi-command package form for new tools); the SDK surface lives at npa.workbench.ros2 and does not go through make_cli_wrapper.
Targets ROS 2 Jazzy (SUPPORTED_ROS_DISTRO = "jazzy"); Jetson Thor nodes run Jazzy + Isaac ROS inside the runtime-fetched container.

Native validation

In an operator-selected Jazzy runtime, source /opt/ros/jazzy/setup.bash and install NPA into a Python environment that can import the native rclpy package:

NPA_INTEGRATION_E2E=1 NPA_ROS2_PREFLIGHT_LIVE=1 \
  PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 \
  npa/.venv/bin/python -m pytest npa/tests/e2e/test_ros2_preflight_live.py -q

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ros2 is a skill published in the GitHub repository nebius/nebius-physical-ai (50 stars, last pushed today), licensed Apache-2.0. It adds 43 tokens to every session and 684 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-11.
