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 | $0.03758 |
| Opus 5 | $0.00026 | $0.01879 |
| Sonnet 5 | $0.00010 | $0.00752 |
| Haiku 4.5 | $0.00005 | $0.00376 |
Grade A, and why
re-script-deob 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.
How it starts
The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.
脚本/宏去混淆（PowerShell / VBA / JavaScript）
何时使用 / 何时不用
- 用：.ps1 / .docm / .xlsm / .js / .jse / .hta 等脚本与宏的混淆还原（编码、字符串拼接、执行链）
- 用：钓鱼附件宏、恶意下载器脚本（[[re-malware]] → [[re-managed]] 路径）
- 不用：编译产物（native 走 [[re-binary-core]]、.NET 走 [[re-dotnet]]、Java 走 [[re-java]]）
- 不用：脚本完全可读（直接读逻辑，无需本技能）
- 注意：动态执行默认沙箱（[[platform-tips]] 最高原则）——静态解码不执行可免沙箱，任何"运行脚本取下一层"的步骤必须进 [[re-sandbox]]
工具准备
参考 [[platform-tips]]——本技能静态解码为主，免沙箱；执行链跟踪中需要运行时（跑脚本/开宏）的步骤按最高原则进沙箱。
python3（解码主力）
- Linux:
apt install python3/dnf install python3/pacman -S python - macOS: 自带；Windows: 官方安装器或
choco install python - 验证:
python3 --version
oletools（VBA 宏提取/解码，可选但强烈建议）
pip install oletools（依赖 pyparsing 自动装上）- 验证:
olevba --help
xxd / sed（十六进制与文本处理）
- Debian/Ubuntu:
apt install xxd（新版本独立包，旧版本在vim-common）；Fedora:dnf install vim-common（xxd 传统由 vim-common 提供，F38+ 也有独立xxd子包）；Arch:pacman -S xxd - macOS: 自带（vim 附送）
- Windows: 无自带 xxd——用 WSL 或 PowerShell
Format-Hex - sed 全平台自带；验证:
xxd -v && sed --version
PowerShell（Windows 内置）/ pwsh（Linux/macOS）
- Windows: 内置
powershell.exe（或 PowerShell 7pwsh） - Linux:
apt install powershell（Microsoft 源）或snap install powershell；macOS:brew install --cask powershell - 验证:
pwsh --version
js-beautify（JS 美化，可选）
pip install jsbeautifier；验证:js-beautify --version
操作步骤
按顺序执行；每层还原结果存档编号（layer_01.ps1 → layer_02.ps1 …），执行链跟踪中"运行脚本拿下一层"的步骤一律在沙箱内。
- 识别脚本类型与混淆风格：
file sample.ps1 && head -c 512 sample.ps1 grep -oiE 'IEX|Invoke-Expression|-EncodedCommand|FromBase64String|eval\(|unescape|fromCharCode|Chr\(|StrReverse|Document_Open|AutoOpen' sample.ps1- PowerShell 特征:
-EncodedCommand/IEX/FromBase64String/[Convert]:: - VBA 特征:
Sub AutoOpen/Document_Open/Chr(/StrReverse/Evaluate/Shell - JS 特征:
eval(/unescape/fromCharCode/\xHH十六进制 /document.write - 混淆风格分类：纯编码（base64/hex/char-code）、字符串拼接（
'co'+'mmand'）、执行链（外层 IEX/eval 嵌套内层载荷）、字符反转/替换
- PowerShell 特征:
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.

re-script-deob is a skill published in the GitHub repository dslsdzc/rev-skills (54 stars, last pushed 14d ago), licensed Apache-2.0. It adds 52 tokens to every session and 3,758 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 2026-09-03.
