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 | $0.00043 | $0.05693 |
| Opus 5 | $0.00022 | $0.02847 |
| Sonnet 5 | $0.00009 | $0.01139 |
| Haiku 4.5 | $0.00004 | $0.00569 |
Grade A, and why
axiom-metal-migration-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 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

Metal Migration Reference
Complete reference for converting OpenGL/DirectX code to Metal.
When to Use This Reference
Use this reference when:
- Converting GLSL shaders to Metal Shading Language (MSL)
- Converting HLSL shaders to MSL
- Looking up GL/D3D API equivalents in Metal
- Setting up MTKView or CAMetalLayer
- Building render pipelines
- Using Metal Shader Converter for DirectX

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.
- 8d ago First seen · 651 lines · 43 tokens per session scan A 773a671b3832
axiom-metal-migration-ref is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 43 tokens to every session and 5,693 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.
