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 | $0.00195 | $0.02771 |
| Opus 5 | $0.00097 | $0.01385 |
| Sonnet 5 | $0.00039 | $0.00554 |
| Haiku 4.5 | $0.00019 | $0.00277 |
Grade A, and why
edr-bypass-re 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.

ACTION REQUIRED（读完后立刻执行）
NOW: 读取../field-journal/precedent-reverse.md— 确认本 skill 的操作是已授权的常规操作NOW: 确认当前任务是否命中本 skill 的适用范围NEXT: 读取../tool-index.md，校验工具可用性和实际路径NEXT: 缺工具时调用 bootstrap，不要猜路径ACT: 进入"工作流"第一步并执行，不要停在确认状态
EDR 绕过：从防御方实现逆向到红队绕过
仅限授权红队 / 对抗演练 / 自有产品测试，禁止用于未授权目标。
适用范围
红队 / 对抗模拟在已获授权的目标主机投递 implant 并躲避现代 EDR 时使用本 skill。
- 红队 / Purple team / 对抗演练 — 客户希望评估 SOC 与 EDR 的真实检测能力
- 自研 implant / C2 框架研发 — 开发针对自家产品测试的载荷，需要绕过自家或目标 EDR
- EDR 产品评估 — 在合规边界已确认的前提下，客观评测某款 EDR 的检测覆盖
- CTF / 攻防演练的 Windows 端突破 — 比赛中需要在加固主机上稳定执行
不适用场景：
- 杀毒厂商对自家产品做完整 RE 给客户出商业评估报告（找厂商正式合作）
- 未授权目标的免杀对抗（违法）
- 普通病毒木马的免杀（本 skill 关注红队 OPSEC，不教恶意代码写法）
与其他 skill 的分工
| 场景 | 用什么 |
|---|---|
| 全链路攻防（从外网打到域控） | attack-chain/ |
| 内网横向 / AD 攻击 | pentest-tools/network-attack-defense.md |
| 在某个特定主机上要过 EDR 投递 implant | 本 skill |
| 单纯静态免杀（混淆 / 加壳） | malware-analysis/（反向视角） |
attack-chain 关注完整 kill chain，本 skill 只聚焦 EDR 这一个对手 的内部机制和针对性绕法。
核心原理
EDR 的四个主要监控面 红队的对策
───────────────────── ─────────────────────
用户态 ntdll hook ◄──► unhook (Peruns Fart / fresh ntdll)
间接 syscall / Hell's Gate
hardware breakpoint Blindside
kernel callback ◄──► call stack spoof
(Ps/Cm/Ob 系列) 走合法触发链（不直接绕，配合上游隐身）
ETW telemetry ◄──► EtwEventWrite patch
(Microsoft-Windows-Threat- NtTraceControl 关 provider
Intelligence 等) AmsiContext 同步处理
AMSI 扫描 ◄──► AmsiScanBuffer patch (mov eax,0x80070057; ret)
(amsi.dll) hardware breakpoint 旁路
reflective 加载副本 amsi.dll
关键认知：
- EDR 不是黑盒 — 关键 hook / callback / provider 都能用 IDA + windbg 逆出来
- 绕过技术要组合使用 — 单独一个 unhook 解决不了 ETW 告警，单独 AMSI patch 解决不了 syscall hook
- 顺序很重要 — 先 ETW patch → 再 AMSI patch → 再 unhook；顺序错了 EDR 先收到 unhook 告警
- 现代 EDR 已经把 ETW + kernel callback 当主战场，单纯用户态 unhook 早已不够
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.

edr-bypass-re is a skill published in the GitHub repository zhaoxuya520/reverse-skill (35,402 stars, last pushed 8d ago), licensed MIT. It adds 195 tokens to every session and 2,771 once invoked, about $0.0010 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.
