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 | $0.00049 | $0.02613 |
| Opus 5 | $0.00024 | $0.01307 |
| Sonnet 5 | $0.00010 | $0.00523 |
| Haiku 4.5 | $0.00005 | $0.00261 |
Grade A, and why
xbim 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 yesterday.
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
The opening of the file, as written. The whole thing — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.

概述
xBIM 模块矩阵:
| 包 | 用途 |
|---|---|

安装
dotnet add package Xbim.Essentials
dotnet add package Xbim.Geometry # 含 C++/CLI,仅 Windows x64 直接可用
dotnet add package Xbim.WindowsUI # WPF 控件(可选)
Linux/macOS:使用
Xbim.Geometry受限;可改用Xbim.Essentials仅做模型解析。Xbim.Essentials(当前 v6.0.x)多目标 .NET 6 / .NET 8。
打开 IFC
using Xbim.Ifc;
using Xbim.Ifc4.Interfaces;
using var model = IfcStore.Open("project.ifc");
foreach (var w in model.Instances.OfType<IIfcWall>())
Console.WriteLine($"{w.GlobalId} {w.Name}");
IfcStore 同时支持 .ifc/.ifczip/.ifcxml;亦可保存 .xbim(Esent 数据库)作为高速缓存。
修改并保存
using var model = IfcStore.Open("a.ifc", null, null);
using (var txn = model.BeginTransaction("rename walls"))
{
foreach (var w in model.Instances.OfType<IIfcWall>())
w.Name = "WALL_" + w.GlobalId;
txn.Commit();
}
model.SaveAs("b.ifc");
model.SaveAs("b.ifczip");
model.SaveAs("b.xbim");
创建新 IFC 模型
using Xbim.Ifc;
using Xbim.Ifc4.MeasureResource;
using Xbim.IO;
var ed = new XbimEditorCredentials {
ApplicationFullName = "MyApp", ApplicationIdentifier = "MyApp",
EditorsOrganisationName = "Org", EditorsFamilyName = "Doe",
EditorsGivenName = "John"
};
using var model = IfcStore.Create(ed, IfcSchemaVersion.Ifc4, XbimStoreType.InMemoryModel);
using (var txn = model.BeginTransaction("init"))
{
var project = model.Instances.New<Xbim.Ifc4.Kernel.IfcProject>(p => p.Name = "Project");
// 单位、上下文 / 站点 / 楼宇 / 楼层 ...
txn.Commit();
}
model.SaveAs("new.ifc");
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.

xbim is a skill published in the GitHub repository znlgis/opengis-skills (60 stars, last pushed 2d ago), licensed MIT. It adds 49 tokens to every session and 2,613 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.
