foxglove

foxglove is a skill for Claude Code from robium-ai/robium. It costs 133 tokens per session (6,690 once invoked), scanned B, a copy of foxglove, MIT.

A guide for viewing live or recorded robot data remotely through Foxglove or Lichtblick, robotics visualization applications, using a WebSocket bridge for ROS 2.

In plain words
What is it for?
It helps set up foxglove_bridge, choose a viewer, connect to live ROS 2 data, and work with recorded MCAP files.
Why use it?
It provides a way to inspect a robot or simulator running without a local display when RViz2 cannot be used directly.

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.

Security

Grade B, and why

foxglove scanned grade B with 2 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 6d 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.

foxglove

The remote/web visualization path for robium: foxglove_bridge exposes a live ROS 2 graph over a WebSocket, and either Foxglove or the open-source Lichtblick client connects to it or opens recorded data. This is the answer environments and gazebo route to whenever a robot or sim runs headless/remote and RViz2's local-display requirement doesn't fit. Two things changed over time and matter for how this skill is used: the bridge itself (foxglove_bridge, MIT-licensed, open source) moved its active development from foxglove/ros-foxglove-bridge (now ROS 1-only, maintenance mode) to the foxglove/foxglove-sdk monorepo, and the app that used to be free/open-source "Foxglove Studio" was discontinued in February 2024 (last open-source release v1.87.0, MPL-2.0) in favor of the current closed-source, commercial Foxglove app, which offers free and paid managed-platform plans. Lichtblick continues the inspectable, self-hostable viewer path as an open-core fork; most of its repository is MPL-2.0. The bridge migration was verified from the two upstream repositories on 2026-07-10. Lichtblick's distribution/license and Foxglove's current pricing and self-hosting terms were re-verified from their official sources on 2026-08-27 (see References); check them again before making procurement or deployment commitments because these terms drift.

When to use this skill

  • Setting up foxglove_bridge on a robot or sim host, choosing Foxglove or Lichtblick as its client, building a layout, recording or replaying an MCAP file, or viewing a robot's data from another machine.
  • The trigger phrases in the description: 'foxglove', 'lichtblick', 'mcap', 'open-source robotics viewer', visualizing a robot on a remote server, sharing visualization, or recording sessions for later analysis.
  • Any time environments or gazebo has already concluded the target is headless/remote and the next question is "how do I actually see it"; this skill is that answer.
  • Cross-references: go to the sibling skill instead when the question is:
    • Whether headless/remote is the deployment target at all, GPU passthrough, or the general local-vs-remote strategy → environments (load first if not already decided; this skill assumes that decision is made and just delivers the viz half of it).
    • Local desktop ROS debugging with a display attached → rviz2.
    • ML/data-centric logging outside ROS message types (policy rollouts, LeRobot episodes) → rerun, though LeRobot dataset episodes can also be served straight to the Foxglove app via lerobot-dataset-viz --display-mode foxglove (invocation is the lerobot skill's territory; verified 2026-07-12, manip-trial).
    • Choosing which viz tool fits the situation at all → visualization (routes here once Foxglove is the right choice).

foxglove is a skill published in the GitHub repository robium-ai/robium (9 stars, last pushed 9d ago), licensed MIT. It adds 133 tokens to every session and 6,690 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). It is 84% identical to foxglove, differing in 239 lines, and is treated as a copy.
