Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 7 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00021 | $0.00536 |
| Opus 5.5 | $0.00008 | $0.00214 |
| Sonnet 5.5 | $0.00004 | $0.00107 |
| Haiku 4.5 | $0.00002 | $0.00054 |
Grade A, and why
isaac-sim 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Isaac Sim
Isaac Sim is a gated simulation stack. Prove the target hardware and release-compatible runtime before designing the robot application around it.
Pass the gate
- Check the current NVIDIA requirements for GPU architecture, VRAM, driver, operating system, RAM, and storage. An NVIDIA compute GPU without the required ray-tracing support is not interchangeable with a supported RTX GPU.
- Isaac Sim does not run on macOS. Use a qualifying remote host or choose a different simulator; do not search for a local workaround.
- Prefer an official, pinned container when local/remote parity matters. Verify the matching NGC tag, EULA requirements, host driver, and GPU passthrough at the time of use.
Build outward from a running simulation
- Runtime: the chosen Isaac Sim release starts cleanly on the target host.
- Scene: the USD stage, physics, units, and robot articulation match the intended application.
- Sensors: frames, rates, ranges, noise, and rendering modes match the real interfaces or the stated synthetic-data purpose.
- Integration: ROS 2 bridge version, distro, graph nodes, clock, and topic contracts agree with the external system.
- Operation: batch jobs run headless; an interactive viewport uses a supported streaming path rather than display forwarding assumptions.
Go deeper only when needed
- Before installing or provisioning, read references/setup-and-requirements.md and re-check its dated values against current NVIDIA documentation.
- For USD, robot import, sensors, or Replicator, read references/scenes-and-sensors.md.
- For the ROS boundary, read references/ros2-integration.md.
- For a remote interactive viewport, read references/webrtc-livestream.md.
- When launch, rendering, streaming, or bridge behavior fails, start with FAILURES.md.
- Isaac Lab owns policy training. Data owns source strategy; Isaac Sim owns the mechanics of generating synthetic data.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

isaac-sim is a skill published in the GitHub repository robium-ai/robium (108 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 536 once invoked, about $0.0001 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 2026-09-03.
