IsaacSim-MCP: Instructions file for Codex

AGENTS.md

IsaacSim-MCP AGENTS.md is an instructions file for Codex, OpenCode from Tim0320/IsaacSim-MCP. It costs 94 tokens per session, scanned A, original, MIT.

Repository instructions for an add-on that connects coding-agent work with NVIDIA Omniverse and Isaac Sim, a tool for building and simulating 3D worlds and robots. They tell the agent which project guidance to load for related requests.

In plain words
What is it for?
They guide repository work, MCP integrations, live scene control, robot and sensor simulations, physics, OpenUSD assets, and Isaac Lab-related requests on Windows.
Why use it?
They provide task-specific rules before work begins, helping protect credentials, live scenes, generated OpenUSD files, and unrelated Git changes. They also distinguish documentation services from live control of Isaac Sim.

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

IsaacSim-MCP AGENTS.md 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.

What it actually says

Agent instructions

For requests involving Omniverse, Isaac Sim, Isaac Lab, OpenUSD, omni, pxr, NVIDIA assets, live stage control, or MCP integration, load and follow .agents/skills/omniverse-windows-workspace/SKILL.md before acting.

Preserve credentials, live scenes, generated USD files, and unrelated Git changes. Distinguish NVIDIA documentation MCP services from this repository's live Isaac Sim control MCP.

Changes

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.
