Reverse Skill is a routing package for AI coding agents that selects appropriate reverse-engineering, penetration-testing, and security-research methods and tools for a given target. It is used for tasks involving APKs, binaries, frontend JavaScript, packet captures, CTF challenges, and authorized penetration testing. Its catalogue add-ons provide the skills and instructions that guide these workflows.
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 | $0.00029 | $0.00639 |
| Opus 5 | $0.00015 | $0.00319 |
| Sonnet 5 | $0.00006 | $0.00128 |
| Haiku 4.5 | $0.00003 | $0.00064 |
Grade A, and why
threat-hunting 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 8d 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
Threat Hunting & Detection Engineering
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
适用场景
- 威胁狩猎（hypothesis-driven）
- Sigma / YARA 检测工程
- 告警调优、误报分析
- 与
malware-analysis/：样本侧 IOC → 本 skill 落地检测 - 与
digital-forensics/：案件伪影 → 横向狩猎
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
| 工具 | 用途 |
|---|---|
| Sigma CLI / sigmac | 规则转换 |
| YARA | 文件/内存 |
| SIEM（ELK/Splunk 等） | 查询 |
| osquery | 端点狩猎 |
| Atomic Red Team | 检测验证（实验室） |

What ships with it
1 file 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.

threat-hunting is a skill published in the GitHub repository zhaoxuya520/reverse-skill (35,595 stars, last pushed 8d ago), licensed MIT. It adds 29 tokens to every session and 639 once invoked, about $0.0001 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.
