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 | $0.00072 | $0.01049 |
| Opus 5 | $0.00036 | $0.00524 |
| Sonnet 5 | $0.00014 | $0.00210 |
| Haiku 4.5 | $0.00007 | $0.00105 |
Grade A, and why
spatial-swiftui-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 5d 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.

Spatial SwiftUI Developer
Quick Start
- If the task is really about surface choice, scene ownership, or file
structure, switch to
spatial-app-architecturefirst. - If the task is about
Chart3D,SurfacePlot, 3D chart marks, orChart3DPose, switch to$swiftui-chart3d-developer. - Pick the rendering track:
Model3Dfor simple asset display,RealityViewfor custom entity graphs and attachments. - Load only the matching reference files.
- Keep loading async and keep RealityKit mutations inside its intended entry points.
- Route build, launch, simulator, and test problems to
build-run-debug.
Load References When
| Reference | When to Use |
|---|---|
swiftui-spatial-overview.md |
When you need the general feature map, examples, and routing guidance for this skill. |
model3d.md |
When using Model3D for async model loading, assets, animation, or manipulation. |
realityview.md |
When setting up RealityView, attachments, or RealityKit integration patterns. |
interaction.md |
When implementing gestures or manipulation patterns for spatial input. |
buttons-and-controls.md |
When implementing visible SwiftUI buttons, links styled as buttons, toolbars, forms, or control surfaces. |
swiftui-scene-lifecycle.md |
When checking official Window, WindowGroup, ImmersiveSpace, open/dismiss, restoration, and launch contracts. |
windowing-immersion.md |
When managing windows, volumetric surfaces, or immersive space transitions. |
spatial-layout.md |
When using SwiftUI spatial layout APIs, sizing, or debug tools. |
Workflow
- Confirm the architecture and scene ownership are already settled.
- Choose the rendering surface:
Model3D,RealityView, window, volume, or immersive scene. - Load only the matching reference files.
- Implement the smallest viable scene and keep mutations in the right layer.
- Summarize the chosen SwiftUI-to-RealityKit integration path.

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.

spatial-swiftui-developer is a skill published in the GitHub repository tomkrikorian/visionOSAgents (60 stars, last pushed 2mo ago), licensed MIT. It adds 72 tokens to every session and 1,049 once invoked, about $0.0004 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.
