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 | $0.00050 | $0.04419 |
| Opus 5 | $0.00025 | $0.02210 |
| Sonnet 5 | $0.00010 | $0.00884 |
| Haiku 4.5 | $0.00005 | $0.00442 |
Grade A, and why
axiom-scenekit 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 9d 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.

SceneKit Development Guide
Purpose: Maintain existing SceneKit code safely and plan migration to RealityKit iOS Version: iOS 8+ (SceneKit), deprecated iOS 26+ Xcode: Xcode 15+
When to Use This Skill
Use this skill when:
- Maintaining existing SceneKit code
- Building a SceneKit prototype (with awareness of deprecation)
- Planning migration from SceneKit to RealityKit
- Debugging SceneKit rendering, physics, or animation issues
- Integrating SceneKit content with SwiftUI
- Loading 3D models via Model I/O or SCNSceneSource
Do NOT use this skill for:
- New 3D projects (use
axiom-realitykit) - AR experiences (use
axiom-realitykit) - visionOS development (use
axiom-realitykit) - SpriteKit 2D games (
axiom-spritekit) - Metal shader programming (
axiom-metal-migration-ref)
Deprecation Context
SceneKit is soft-deprecated as of iOS 26 (WWDC 2025). This means:
- Existing apps continue to work
- No new features or general bug fixes
- Only critical security patches
SceneView(SwiftUI) is formally deprecated in iOS 26
Apple's forward path is RealityKit. All new 3D projects should use RealityKit. SceneKit knowledge remains valuable for maintaining legacy code and understanding concepts during migration.
In RealityKit: ECS architecture replaces scene graph. See axiom-scenekit-ref for the complete concept mapping table.
1. Mental Model
Scene Graph Architecture
SceneKit uses a tree of nodes (SCNNode) attached to a root node in an SCNScene. Each node has a transform (position, rotation, scale) relative to its parent.
SCNScene
└── rootNode
├── cameraNode (SCNCamera)
├── lightNode (SCNLight)
├── playerNode (SCNGeometry + SCNPhysicsBody)
│ ├── weaponNode
│ └── particleNode (SCNParticleSystem)
└── environmentNode
├── groundNode
└── wallNodes
In RealityKit: Entities replace nodes. Components replace node properties. The hierarchy concept persists, but behavior is driven by Systems rather than node callbacks.
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.

axiom-scenekit is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 50 tokens to every session and 4,419 once invoked, about $0.0003 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 2026-09-03.
