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.

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 | $0.01717 | $0.01717 |
| Opus 5 | $0.00859 | $0.00859 |
| Sonnet 5 | $0.00343 | $0.00343 |
| Haiku 4.5 | $0.00172 | $0.00172 |
Grade A, and why
cloudxr-js-samples AGENTS.md scanned grade A with 1 finding 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What This Is
CloudXR.js is a TypeScript SDK that streams VR/AR from a GPU server to a web browser via WebRTC. The server renders; the browser displays video and sends back head/hand tracking.
Commands
# Download latest SDK from NGC (update version as needed)
SDK_VERSION="6.1.0"
SDK_FILE="nvidia-cloudxr-${SDK_VERSION}.tgz"
curl -fL -o "${SDK_FILE}" \
"https://api.ngc.nvidia.com/v2/resources/nvidia/cloudxr-js/versions/${SDK_VERSION}/files/${SDK_FILE}?download=true"
# Install SDK + run any sample
cd simple/ && npm install "../${SDK_FILE}" && npm run dev # Vanilla WebGL
cd react/ && npm install "../${SDK_FILE}" && npm run dev # React Three Fiber
# Peer deps the app must provide: gl-matrix, long
When Scaffolding a New Client
- Import:
import { createSession, SessionState } from '@nvidia/cloudxr'; - Obtain a WebXR session (use
optionalFeatures: ['local-floor']— recommended, not required) - Get a
WebGL2RenderingContextandXRReferenceSpace - Call
createSession(options, delegates)— see required fields below - Call
session.connect() - In the XR
requestAnimationFrameloop: callsendTrackingStateToServer(time, frame)thenrender(time, frame, layer)

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.

cloudxr-js-samples AGENTS.md is an instructions file published in the GitHub repository NVIDIA/cloudxr-js-samples (22 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 1,717 tokens to every session, about $0.0086 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
