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.

What it costs to keep this loaded
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 | $0.00045 | $0.01535 |
| Opus 5 | $0.00023 | $0.00767 |
| Sonnet 5 | $0.00009 | $0.00307 |
| Haiku 4.5 | $0.00005 | $0.00153 |
Grade A, and why
unreal-modeling-normals 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 11d 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.

建模 — 法线与切线
前置条件：先阅读 unreal-modeling。
库
CDO：/Script/GeometryScriptingCore.Default__GeometryScriptLibrary_MeshNormalsFunctions
TargetMesh 为 UDynamicMesh* 路径字符串。Debug 省略。需要 FGeometryScriptMeshSelection 的函数，用 MeshOperationLibrary 桥接。需要 FGeometryScriptVectorList 的函数，用 MakeVectorList/GetVectorListArray 桥接。

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.
- 11d ago First seen · 112 lines · 45 tokens per session scan A 14e62a64ef3e
unreal-modeling-normals is a skill published in the GitHub repository Italink/UnrealClientProtocol (125 stars, last pushed 13d ago), licensed MIT. It adds 45 tokens to every session and 1,535 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 2026-08-30.
