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 | $0.00066 | $0.02816 |
| Opus 5 | $0.00033 | $0.01408 |
| Sonnet 5 | $0.00013 | $0.00563 |
| Haiku 4.5 | $0.00007 | $0.00282 |
Grade A, and why
re-doc-malware 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 — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
恶意文档分析
何时使用 / 何时不用
- 用：钓鱼附件（PDF/Office/RTF）、文档漏洞利用样本、宏文档、文档型恶意载荷
- 用：仅拿到单文档样本，需还原载荷提取链（宏 → 脚本 → 可执行 → 回连）
- 不用：纯脚本宏（转 [[re-script-deob]]）；文档仅是载体（核心逻辑在下载载荷）
- 不用：只有网页/邮件网关侧元数据（无样本文件本身）——先要样本再分析
- 注意：动态打开文档必须沙箱（[[re-sandbox]]，[[platform-tips]] 最高原则）；文档可能检测环境后不触发（见坑 6）
工具准备
pdf-parser / pdfid（PDF 结构分析）
- Linux:
apt install pdf-parser pdfid（Kali 常预装；Debian/Ubuntu 仓库同名包）或 GitHubDidierStevens/DidierStevensSuite源码运行；macOS:brew install pdf-parser/ pip - Windows: pip（WSL 亦可）
- 验证:
pdf-parser --version（无则python3 pdf_parser.py --help）；pdfid.py sample.pdf能输出对象计数 - 补充（备注：peepdf 已归档、Python 2 时代，PyPI 仅 0.3.6——首选 pdf-parser/pdfid）
qpdf（PDF 流解压，可选）
- Linux:
apt install qpdf；macOS:brew install qpdf - 验证:
qpdf --version - 用途: 展开对象流/压缩流为可读形式（
qpdf --qdf --object-streams=disable in.pdf out.pdf），配合-ddump 对照
olevba / rtfobj（Office/RTF 宏与嵌入对象提取）
- 多平台:
pip install oletools（oletools 内含 olevba、rtfobj、oleobj、msodde、oleid、mraptor 等） - 验证:
olevba --help；rtfobj --help - 注意: oledump 不在 oletools 包内——是独立工具（GitHub
DidierStevens/DidierStevensSuite取 oledump.py，需pip install olefile依赖；python3 oledump.py -s <流号> <文件>按流转储）
xlmdeobfuscator（Excel 4.0 宏去混淆，可选）
pip install xlmdeobfuscator- 验证:
xlmdeobfuscator --help - 适用: .xls 里的 XLM 宏表（olevba 0.54+ 已能识别 XLM，混淆深时用本工具还原）
LibreOffice（沙箱打开验证，可选）
- Linux:
apt install libreoffice/dnf install libreoffice；macOS:brew install --cask libreoffice；Windows: 官方安装包 - 验证:
libreoffice --version - 注意: LibreOffice 默认不执行 VBA 宏（宏安全性限制）——沙箱里要验证宏行为需装真实 Office 或改 LibreOffice 宏安全设置（见 [[gotchas]]）
7z（OLE/OOXML 解包）
- Linux:
apt install p7zip-full；macOS:brew install sevenzip；Windows: 官方安装包 - 验证:
7z --help - 7z 可直接列出 OLE 复合文档内部流（WordDocument/1Table/VBA/PROJECT 等）与 OOXML 包内文件
操作步骤
按顺序执行；每步产物存档（路径 + sha256，见 [[re-triage]]）。
- 文档类型识别：
file sample.pdf sample.docm sample.rtf- PDF：
%PDF头；Office 旧格式：CFB（OLE 复合文档，D0 CF 11 E0）；OOXML：zip（PK）；RTF：{\rtf - 类型决定后续工具链；多类型混合（如 PDF 内嵌 OLE）按各分支分别走
- PDF：
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-doc-malware is a skill published in the GitHub repository dslsdzc/rev-skills (50 stars, last pushed 11d ago), licensed Apache-2.0. It adds 66 tokens to every session and 2,816 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.
