lichtblick

lichtblick is a skill for Claude Code, Codex from nebius/nebius-physical-ai. It costs 41 tokens per session (1,987 once invoked), scanned A, original, Apache-2.0.

A guide for deploying and reviewing Lichtblick, an open-source browser viewer for MCAP, ROS bag, and other robotics log files. It describes the CPU-only service, its S3 artifact inputs, and its command-line interfaces.

In plain words
What is it for?
Use it to serve existing MCAP recordings from object storage, package robotics artifacts, and review Lichtblick deployment settings.
Why use it?
It gives a defined way to inspect recorded robotics data in a web viewer without requiring a GPU or a Foxglove account. It also distinguishes Lichtblick from the proprietary Foxglove product.

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 A, and why

lichtblick 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 3d 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.

Lichtblick

Lichtblick is an open-source (MPL-2.0), Foxglove-compatible MCAP / ROS-bag / robotics log viewer. It is the browser-based analog of rerun-viewer: a static web viewer that opens artifacts, with no GPU. The image ships Lichtblick (lichtblick-suite/lichtblick), the actively maintained community fork of the archived, relicensed Foxglove Studio. It is a distinct product from the now-proprietary Foxglove; no Foxglove account or proprietary component is required.

  • Tool name: lichtblick — Image: npa-lichtblick — Port: 8080 — Tier: service.
  • Pinned OSS version: Lichtblick 1.26.0 ([tool.npa.supported-tools]).
  • CPU-only; not part of the cuda12 / cuda13-b300 tag families.

Related: skills/tools/foxglove/SKILL.md covers the official Foxglove app embedded with the @foxglove/embed SDK, the MCAP converter (npa workbench foxglove convert-run), and the agent's Foxglove pane — which falls back to this viewer when no Foxglove account is configured.

Interfaces

CLI:

# View an existing MCAP (plan only by default; --execute stages + launches):
npa workbench lichtblick serve --input-path s3://bucket/run/recording.mcap --execute

# Pack a robot camera-frame sequence (e.g. sim2real rollout/augment frames) into
# a real MCAP of foxglove.CompressedImage messages, then serve it:
npa workbench lichtblick serve \
  --input-path s3://bucket/sim2real-b/<run-id>/augment/frames/ \
  --from-frames --fps 10 --topic /sim2real/augment/camera --execute

npa workbench lichtblick launch  # alias for serve
npa workbench lichtblick status
npa workbench lichtblick list

# Decode an MCAP into a native Rerun .rrd so Rerun renders it too (Rerun's built-in
# MCAP loader keeps foxglove/JSON messages as raw blobs; this maps the well-known
# schemas to archetypes). Open the result with `rerun x.rrd` or `sim2real rerun serve`.
npa workbench lichtblick to-rerun \
  --input-path s3://bucket/sim2real-b/<run-id>/reports/sim2real.mcap \
  --output-path <run-id>.rrd --execute

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.
