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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 163 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
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 | $0.00070 | $0.06356 |
| Opus 5 | $0.00035 | $0.03178 |
| Sonnet 5 | $0.00014 | $0.01271 |
| Haiku 4.5 | $0.00007 | $0.00636 |
Grade A, and why
ara3d-sdk 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.
How it starts

Ara3D.SDK｜ Ara 3D 官网： https://ara3d.com许可证： MIT ｜ 最新版本：
1.6.1（由仓库Directory.Build.props的Ara3DVersion统一管理，所有包共享同一版本号）｜ 默认分支：main｜ 目标框架：net8.0/net8.0-windows
概述
Ara3D-SDK 是面向 AEC / BIM / 数字孪生 / 三维 GIS 场景的高性能 .NET 三维数据处理引擎与 Studio 插件框架。它有两大定位：
- 独立的高性能三维/BIM 工具库：加载、生成、变换、导出海量三维几何与 BIM 数据；
- Ara 3D Studio 桌面应用的扩展底座：通过
Ara3D.Studio.API编写生成器、修改器、命令与工具，把自研算法接入 Studio 的可视化流程图（Flow Graph）。
核心工程亮点：
| 能力 | 说明 |
|---|---|
| 统一高性能内存模型 | Ara3D.Memory 提供 64 字节对齐的非托管缓冲区、ByteSlice、内存映射文件视图，服务 SIMD 与超大数据集 |
| SIMD 加速数学 | Ara3D.F8（AVX 8 宽 float）+ Plato DSL 生成的 Vector3/Matrix4x4/Quaternion/Number/Angle 等数学类型 |
| 不可变几何内核 | TriangleMesh3D/QuadGrid3D 的所有变换均返回新对象，天然适合函数式管线与并行 |
| BIM 开放模式（BOS） | 把 IFC/Revit 数据规约为列式 EAV 结构，可落地为 Parquet / DuckDB / Excel |
| 可插拔 Studio 框架 | 几十行代码写出参数化生成器或网格修改器，实时预览 |
| 零/少外部依赖 | 大多数库零外部 NuGet 依赖，便于审计与集成 |
一句话定位：Ara3D-SDK 是「面向 AEC 的高性能 .NET 三维数据处理引擎 + Studio 插件框架」，代码结构清晰、几乎零外部依赖，也是学习现代高性能 .NET 图形/BIM 工程的范本。
版本提示： Ara3D-SDK 处于活跃开发中，具体类名与方法签名可能随版本演进。请以你实际引用的 NuGet 包版本与源码为准，并让所有 Ara3D 包保持同一版本号。

关键原则：只有 src/ 与 ext/ 下的库会被打包成 NuGet（见 build/packages.txt）；toolchain/、tests/、apps/、examples/ 等永不进入发布产物。
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 · 412 lines · 70 tokens per session scan A 47197bd5cc15
ara3d-sdk is a skill published in the GitHub repository znlgis/opengis-skills (60 stars, last pushed yesterday), licensed MIT. It adds 70 tokens to every session and 6,356 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.
