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 | $0.00038 | $0.03545 |
| Opus 5 | $0.00019 | $0.01773 |
| Sonnet 5 | $0.00008 | $0.00709 |
| Haiku 4.5 | $0.00004 | $0.00354 |
Grade A, and why
axiom-scenekit-ref 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 API Reference & Migration Mapping
Complete API reference for SceneKit with RealityKit equivalents for every major concept.
When to Use This Reference
Use this reference when:
- Looking up SceneKit → RealityKit API equivalents during migration
- Checking specific SceneKit class properties or methods
- Planning which SceneKit features have direct RealityKit counterparts
- Understanding architectural differences between scene graph and ECS

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.
- 9d ago First seen · 347 lines · 38 tokens per session scan A 2f7a77d995b7
axiom-scenekit-ref is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 38 tokens to every session and 3,545 once invoked, about $0.0002 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.
