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 5.1 | $0.00144 | $0.01616 |
| Opus 5 | $0.00072 | $0.00808 |
| Sonnet 5 | $0.00029 | $0.00323 |
| Haiku 4.5 | $0.00014 | $0.00162 |
Grade A, and why
realitykit-visionos-developer 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 8d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RealityKit visionOS Developer
Quick Start
- Classify the request as core scene setup, rendering/materials, animation/physics, audio, custom ECS, USD authoring, Spatial Preview, SwiftUI UI, ARKit provider work, or build/debug plumbing.
- Stay in this skill for RealityView setup, entity loading, component
selection, input, attachments, anchoring, portals, synchronization, and
the local
USDStageComponentbridge. - Switch to the focused RealityKit skill when the task is primarily visual, animated, physical, audio, or custom ECS behavior.
- Load only the narrow reference files needed for the task.
- Keep all scene mutation inside documented RealityKit entry points:
RealityViewcontent/update closures, event handlers, or registered systems.

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.

realitykit-visionos-developer is a skill published in the GitHub repository tomkrikorian/visionOSAgents (60 stars, last pushed 2mo ago), licensed MIT. It adds 144 tokens to every session and 1,616 once invoked, about $0.0007 per session on Opus 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 2026-08-30.
