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 | $0.00056 | $0.03416 |
| Opus 5 | $0.00028 | $0.01708 |
| Sonnet 5 | $0.00011 | $0.00683 |
| Haiku 4.5 | $0.00006 | $0.00342 |
Grade A, and why
re-dotnet 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.

.NET CIL 逆向（dnSpy / ILSpy / de4dot）
何时使用 / 何时不用
- 用：确认是 .NET 程序集（PE CLI header /
file输出 "Mono/.Net assembly"）后，还原 CIL 为可读 C#；处理 ConfuserEx/SmartAssembly 等 .NET 混淆；定位注册码/网络/解密逻辑 - 用：恶意 .NET 样本（[[re-malware]] → [[re-managed]] 路径）的静态还原
- 不用：非托管 PE（native 程序直接 [[re-binary-core]]；混合模式程序 native 部分同样转出）
- 不用：Java（[[re-java]]）、脚本（[[re-script-deob]]）
- 注意：动态步骤默认沙箱（[[platform-tips]] 最高原则）；先
file/初勘确认再动手
工具准备
参考 [[platform-tips]]——反编译/去混淆为静态步骤，免沙箱；动态验证按最高原则进沙箱。
dotnet SDK（跑 .NET 工具的前提）
- Debian/Ubuntu:
apt install dotnet-sdk-8.0（官方 Microsoft 源） - Fedora:
dnf install dotnet-sdk-8.0；Arch:pacman -S dotnet-sdk - macOS:
brew install --cask dotnet-sdk - Windows:
choco install dotnet-sdk或官方安装器 - 验证:
dotnet --version
ILSpy（跨平台，GUI + CLI）
- CLI（dotnet tool）:
dotnet tool install -g ilspycmd - GUI: GitHub
icsharpcode/ILSpyrelease zip（linux-x64 / win-x64 / osx-x64 均有） - 验证:
ilspycmd --help；GUI 能打开程序集
dnSpy（Windows 专用，GitHub release）
- GitHub
dnSpyEx/dnSpyrelease zip → 解压运行dnSpy.exe - 仅 Windows（WinForms + .NET Framework）；Linux/WSL 用 ILSpy（或 Wine 跑 dnSpy）
- 验证: GUI 启动并能
File > Open程序集 - 优势: 反编译 + 编辑 + 调试一体
de4dot（GitHub release，去混淆）
- GitHub
de4dot/de4dotreleasede4dot.exe；Linux/macOS 需 mono:apt install mono-devel/dnf install mono-devel；Arch:yay -S mono-git（AUR——mono 自 2021 年起不在官方仓库，AUR 亦无稳定mono包，仅mono-git）；macOSbrew install mono- 运行:
mono de4dot.exe --help；Windows 直接de4dot.exe --help
- 验证:
--help正常输出
单文件 bundle 解包（sfextract / ILSpy 内置，可选但常用）
- 零额外工具: ILSpy 7.1+ GUI 直接
File > Open单文件 bundle，7.2+ 右键Extract package entry导出内嵌程序集 - CLI:
dotnet tool install -g sfextract（Droppers/SingleFileExtractor，MIT；注意dotnet-bundle-extractor/dotnet-bundle-extract这两个包名在 NuGet 并不存在） - 用法:
sfextract sample.exe -o extracted/（不带-o只列出 bundle 内文件） - 验证:
sfextract --help
操作步骤
按顺序执行，每步记录证据（路径 + sha256，见 [[re-triage]]）。
- 识别 .NET 程序集：
CLI header 确认（PE 数据目录第 15 项 = COM Descriptor）：file sample.exe # 含 "Mono/.Net assembly" 即 .NET strings sample.exe | grep -i mscoree # mscoree.dll 导入是经典标识
注意混合模式程序集（native + 托管都看得到）与自包含单文件（见坑 4）。 CLI header 结构速查（实测 .NET 10 产物）：cb=0x48(72)、MajorRuntimeVersion=2、MinorRuntimeVersion=5、MetaData RVA、EntryPoint RVA（0=DLL）、CorFlags（1=ILONLY、2=32BITREQUIRED、0x8=强名签名（COMIMAGE_FLAGS_STRONGNAMESIGNED）、0x20000=32BITPREFERRED）。 元数据根（MetaData RVA 处）：签名import pefile pe = pefile.PE('sample.exe') dd = pe.OPTIONAL_HEADER.DATA_DIRECTORY[14] # COM Descriptor (CLI header) print(hex(dd.VirtualAddress), hex(dd.Size)) # 非 0 → 托管程序集BSJB(0x424A5342) + 版本 1.1 + 保留 + 版本串长 + 版本串（"v4.0.30319"，.NET Framework/.NET Core/.NET 10 产物恒定）+ flags(2) + 流数(2) + 流头（offset + size + 名字，4 字节对齐）。 流名即内容形态：#~（压缩表，Roslyn 默认）/#-（未压缩表）、#Strings（元数据字符串池）、#US（用户字符串：代码里的 C# 字面量）、#GUID、#Blob（签名/常量 blob）——字符串加密样本的明文不在#US就是运行时拼的；#~的表内容即 dnSpy/ILSpy 的类型/方法树。
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 · 130 lines · 56 tokens per session scan A 8e1368dee35b
re-dotnet is a skill published in the GitHub repository dslsdzc/rev-skills (50 stars, last pushed 11d ago), licensed Apache-2.0. It adds 56 tokens to every session and 3,416 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.
