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 | $0.00064 | $0.01847 |
| Opus 5.5 | $0.00026 | $0.00739 |
| Sonnet 5.5 | $0.00013 | $0.00369 |
| Haiku 4.5 | $0.00006 | $0.00185 |
Grade A, and why
visionos-swift-spatial 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 7d 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.

visionOS & Swift Spatial Computing Guidelines
This skill provides architectural guidance, SwiftUI spatial container paradigms, RealityKit 3D rendering patterns, ARKit hand/plane tracking models, and performance standards for building native visionOS applications on Apple Vision Pro.
1. visionOS Spatial App Architecture
visionOS divides spatial user interfaces into three distinct presentation containers:
+-------------------------------------------------------------------------+
| Shared Space |
| |
| +-----------------------+ +--------------------+ |
| | 2D Window | | 3D Volume | |
| | (SwiftUI Standard) | | (Bounded Reality) | |
| +-----------------------+ +--------------------+ |
+-------------------------------------------------------------------------+
|
(User Enters Full Space)
v
+-------------------------------------------------------------------------+
| Full Space |
| |
| +-----------------------------------------------------------------+ |
| | ImmersiveSpace | |
| | (Unbounded 3D World / Full Pass-through / VR) | |
| +-----------------------------------------------------------------+ |
+-------------------------------------------------------------------------+
- Window: Standard 2D or semi-3D SwiftUI plane residing within the user's Shared Space alongside other applications.
- Volume: Bounded 3D bounding box container displaying 3D RealityKit content alongside windows in Shared Space.
- Immersive Space: Exclusive environment (Mixed, Progressive, or Full) granting total access to surrounding spatial coordinates and ARKit tracking feeds.
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.
- 7d ago First seen · 216 lines · 64 tokens per session scan A 0fe83c052df9
visionos-swift-spatial is a skill published in the GitHub repository hamzabellouch/agent-skills (8 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 1,847 once invoked, about $0.0003 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 2026-10-10.
