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.

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 | $0.00077 | $0.00586 |
| Opus 5 | $0.00039 | $0.00293 |
| Sonnet 5 | $0.00015 | $0.00117 |
| Haiku 4.5 | $0.00008 | $0.00059 |
Grade A, and why
analyzing-linux-kernel-rootkits 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 5d 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.
What it actually says
分析 Linux 内核 Rootkit
概述
Linux 内核 rootkit 在 ring 0 层级运行，通过修改内核数据结构来对用户态工具隐藏进程、文件、网络连接和内核模块。检测方法需要使用内存取证（使用 Volatility3 分析物理内存转储）或交叉视图分析（比对 /proc、/sys 和内核数据结构的不一致性）。本 skill 涵盖使用 Volatility3 Linux 插件检测 syscall 表 hook、隐藏内核模块和被修改的函数指针，以及使用 rkhunter 和 chkrootkit 进行实时系统扫描。
前置条件
- 已安装 Volatility3（pip install volatility3）
- Linux 内存转储（通过 LiME、AVML 或 /proc/kcore 获取）
- 与目标内核版本匹配的 Volatility3 Linux 符号表（ISF）
- 用于实时系统扫描的 rkhunter 和 chkrootkit
- 用于比对的已知良好内核镜像
步骤
步骤 1：获取内存转储
使用 LiME 内核模块或针对云实例的 AVML 捕获 Linux 物理内存。
步骤 2：使用 Volatility3 分析
运行 linux.check_syscall、linux.lsmod、linux.hidden_modules 和 linux.check_idt 插件以检测 rootkit 痕迹。
步骤 3：交叉视图分析
比较来自 /proc/modules、lsmod 和 /sys/module 的模块列表，识别在某一视图中隐藏但在另一视图中存在的模块。
步骤 4：实时系统扫描
运行 rkhunter 和 chkrootkit，检测已知 rootkit 特征、可疑文件和被修改的系统二进制文件。
预期输出
JSON 报告，包含检测到的 syscall hook、隐藏内核模块、被修改的 IDT 条目、可疑的 /proc 差异以及 rkhunter 发现。
What ships with it
3 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.

analyzing-linux-kernel-rootkits is a skill published in the GitHub repository killvxk/cybersecurity-skills-zh (44 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 77 tokens to every session and 586 once invoked, about $0.0004 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.
