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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 30 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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 | $0.00030 | $0.00643 |
| Opus 5 | $0.00015 | $0.00321 |
| Sonnet 5 | $0.00006 | $0.00129 |
| Haiku 4.5 | $0.00003 | $0.00064 |
Grade A, and why
thick-client 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 4d 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.

Thick Client Security Testing
ACTION REQUIRED（读完后立刻执行）
NOW: 读取../field-journal/precedent-pentest.mdNOW: 确认目标是 桌面厚客户端（Win/macOS/Linux GUI 或服务伴生），非纯 WebNOW: case-init；安装包来源与测试账号写入 scopeNEXT: 工具（Burp 上游代理、进程监控、逆向工具）ACT: 信任边界图 → 本地面 → 网络面 → 更新/供应链
适用场景
- C/S 架构客户端、Electron/Qt/.NET WinForms/WPF
- 本地配置/凭证存储、IPC、命名管道
- 客户端强制校验绕过研究（授权）
- 自动更新通道与代码签名验证
工作流
1. 建边界
□ 进程树、子进程、驱动/服务
□ 监听端口与出站域名
□ 本地敏感路径：%APPDATA%、Keychain、注册表
2. 本地攻击面
□ 明文配置、硬编码密钥、调试开关
□ DLL 劫持/搜索顺序（Windows）
□ 数据库文件（SQLite）权限与加密
□ IPC：谁可连接？是否鉴权？
3. 网络面
□ 系统代理 / 应用自定义 TLS
□ 证书钉扎 → 联合 mobile/js 方法学或 Frida
□ API 越权：客户端隐藏的管理接口
4. 逆向验证
□ .NET → dotnet-reverse；原生 → ida/ghidra；Electron → asar + js-reverse

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.
- 4d ago First seen · 80 lines · 30 tokens per session scan A 714f7e2499b5
thick-client is a skill published in the GitHub repository zhaoxuya520/reverse-skill (35,027 stars, last pushed 4d ago), licensed MIT. It adds 30 tokens to every session and 643 once invoked, about $0.0002 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.
