What it does
Threat Hunting is an agent skill from zhaoxuya520/reverse-skill. Use for blue-team threat hunting, detection engineering with Sigma/YARA, SIEM query design, and incident detection validation.
Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/hunting-loop.md`).
It sits in Security, covering Security operations. The repository describes itself as: Reverse Engineering / Authorized Penetration Testing / Security Research Skill Router Pack AI-powered routing + On-demand toolchain bootstrapping + Self-evolving knowledge base…. The licence is MIT.
When your agent uses it
- Blue-team threat hunting
- Detection engineering with Sigma/YARA
- SIEM query design
- Incident detection validation
Example prompts
- “/threat-hunting”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cab634b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Threat Hunting loads about 344 tokens when it runs, and up to ~390 if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 83 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: warnings
The automated check found patterns that need a careful read before installing.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ACTION REQUIRED（读完后立刻执行）
NOW: 确认蓝队/狩猎授权与数据源范围（SIEM、EDR 导出）NOW: 明确假说（hypothesis）再查数，避免无脑刷告警NEXT: 工具与数据接入方式ACT: 假说 → 查询 → 验证 → 规则化

工作流
1. 建假说
例：攻击者用 living-off-the-land 做横向
→ 数据源：Sysmon 1/3/10、Windows Security 4624/4648
→ 成功标准：发现异常父进程或罕见账户日志源2. 查询与堆叠
□ 基线：正常管理员行为时段与主机
□ 异常：新服务、编码 PowerShell、异常出站
□ 关联：同账号多主机短时登录3. 规则化
# Sigma 骨架见 malware-analysis；本 skill 强调：
# - 误报面
# - 数据源字段映射
# - 响应 playbook 链接4. 验证
□ 原子测试（Atomic Red Team）仅在授权实验室
□ 回放历史日志验证召回工具链
