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 | $0.00052 | $0.01422 |
| Opus 5 | $0.00026 | $0.00711 |
| Sonnet 5 | $0.00010 | $0.00284 |
| Haiku 4.5 | $0.00005 | $0.00142 |
Grade A, and why
unreal-modeling-selection 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.

建模 — 选择
前置条件：先阅读 unreal-modeling。
重要说明
FGeometryScriptMeshSelection 内部使用不可序列化的 TSharedPtr<FGeometrySelection> 存储数据，无法通过 UCP JSON 直接创建或传递选择内容。
创建选择的两种方式：
- MeshOperationLibrary 桥接函数（推荐用于简单选择）：
SelectAllTriangles、SelectTrianglesByIDs、SelectVerticesByIDs、SelectPolygroupByID、SelectMaterialByID——见unreal-modeling核心 Skill - GeometryScript 原生选择函数（本 Skill）：
SelectMeshElementsInSphere、SelectMeshElementsByNormalAngle等——适用于基于几何条件的复杂选择
创建后的 Selection 可作为参数传给其他 GeometryScript 函数（UV、变形、简化等）。

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 · 115 lines · 52 tokens per session scan A bd24411c348f
unreal-modeling-selection is a skill published in the GitHub repository Italink/UnrealClientProtocol (125 stars, last pushed 11d ago), licensed MIT. It adds 52 tokens to every session and 1,422 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 2026-08-30.
