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 | $0.00033 | $0.03531 |
| Opus 5 | $0.00016 | $0.01766 |
| Sonnet 5 | $0.00007 | $0.00706 |
| Haiku 4.5 | $0.00003 | $0.00353 |
Grade A, and why
re-license 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 9d 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.

授权验证逻辑分析（注册校验定位）
何时使用 / 何时不用
- 边界（继承 [[re-cracking]]）：仅限自有软件 / 授权测试 / CTF·研究环境；禁止未授权软件解锁与商业软件绕过；断点观察返回值等动态步骤前，用户须说明目标归属（所有权 / 测试授权 / 研究环境）
- 用：程序有注册 / 激活流程（输入序列号、注册码、授权文件），需要定位"在哪校验、怎么校验"
- 用：破解前置——为 [[re-patching]] / [[re-keygen]] 提供校验点地址与校验算法
- 用：判断授权是在线激活还是离线校验；识别机器码绑定、有效期 / 订阅型授权
- 不用：目标已定位校验分支、只改字节绕过（直接 [[re-patching]]）
- 不用：确认无授权机制（无注册 UI / 注册表 / 授权文件读取——诚实告诉用户，见坑 5）
- 不用：只做协议层分析（在线激活的流量分析走 [[re-protocol]]）
- 注意：样本带壳先脱壳（[[re-anti-analysis]]）；校验函数被混淆先 [[re-deobfuscate]]（见坑 1）；动态环节沙箱执行（[[re-sandbox]]，[[platform-tips]] 最高原则）
工具准备
调试器（按 OS）
- Linux / Wine 下调试 PE: [[re-gdb]] ——
apt install gdb/dnf install gdb/pacman -S gdb，验证gdb --version；Wine 直读：wine sample.exe运行后gdb -p <pid>attach（[[platform-tips]] Linux 分支） - Windows: [[re-x64dbg]] —— 官方 release zip，attach 需管理员权限（[[platform-tips]] Windows 分支）；验证：载入样本能单步
- macOS: [[re-lldb]] ——
brew install lldb，验证lldb --version；attach 前检查 Developer Tools 授权（[[platform-tips]] macOS 分支） - WSL: 无法 attach Windows 进程——跨边界分析走 Windows 侧工具，WSL 内只做静态（[[platform-tips]] WSL 分支）
反编译器（[[re-ghidra]] 等，交叉引用工作台）
- Ghidra:
apt install ghidra/dnf install ghidra/pacman -S ghidra/brew install --cask ghidra，验证analyzeHeadless -help（安装细节见 [[re-ghidra]]） - 替代: [[re-ida]]（
idat64 -Aheadless）、[[re-radare2]]（apt install rizin，验证rizin -v） - 作用：strings / API 的交叉引用（xref）是"谁在调用注册相关函数"的关键
strings —— 可打印串快速扫描（全平台）
- Linux:
apt install binutils/dnf install binutils/pacman -S binutils（多数自带） - macOS: 系统自带 /usr/bin/strings
- Windows/WSL: WSL 内 Linux 版；Windows 本机用 Sysinternals
strings.exe - 验证:
strings --version
动态补充（可选）：strace / ltrace / ProcMon
- Linux:
apt install strace ltrace，验证strace --version；观察注册表（Wine 下）/ 文件 / API 调用（详见 [[re-tracing]]） - Windows: Sysinternals Process Monitor（官网下载独立 exe，无包管理器）——注册表 / 文件 / 进程 / 网络全量 trace（[[re-behavior]] 衔接）；注册表操作是授权读取的主路径
操作步骤
按顺序执行，每步记录结果（校验点地址 + 证据路径，见 [[re-triage]]）。产物：全部校验点清单 + 校验算法，交给 [[re-patching]] / [[re-keygen]]。
What ships with it
2 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.
- 9d ago First seen · 120 lines · 33 tokens per session scan A c503c11c8206
re-license is a skill published in the GitHub repository dslsdzc/rev-skills (54 stars, last pushed 14d ago), licensed Apache-2.0. It adds 33 tokens to every session and 3,531 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.
