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 | $0.00038 | $0.03925 |
| Opus 5 | $0.00019 | $0.01962 |
| Sonnet 5 | $0.00008 | $0.00785 |
| Haiku 4.5 | $0.00004 | $0.00392 |
Grade A, and why
re-patching 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.

补丁制作（字节级 patch / 指令重写）
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；先对样本副本操作（[[re-ghidra]]/[[re-ida]] 保存副本或导出临时 Program），禁止直接 patch 原始样本破坏证据链
- 用：已从 [[re-license]] 定位校验点，需要改字节绕过验证 / 修改行为（解锁功能、跳过校验）
- 用：校验算法不可逆（哈希 / 非对称验签）时替代注册机（见 [[re-keygen]] 坑 1）
- 用：分发场景（补丁文件小、不改动原始文件分发）
- 不用：校验点都还没定位（先 [[re-license]]）
- 不用：需要为正版用户生成合法序列号（算法可逆 → 走 [[re-keygen]] 更优雅，不修改目标）
- 不用：只改内存不落盘（会话级 hook 走 [[re-frida]]；调试器内修改不存档不算补丁）
- 注意：补丁版验证必须在沙箱（[[re-sandbox]]，[[platform-tips]] 最高原则）；修改前备份原文件（见坑 1）
工具准备
十六进制编辑器
- Linux:
apt install hexedit/dnf install hexedit/pacman -S hexedit，验证hexedit --version（交互式按 F2 保存） - Windows: HxD（官方免费下载，便携版免安装）；或 010 Editor（商业，模板解析强）
- macOS:
brew install hexedit - WSL: WSL 内 Linux 版；跨边界文件编辑用 Windows 侧 HxD（[[platform-tips]] WSL 分支）
调试器（按 OS，定位 patch 点 / 确认分支方向）
- Linux / Wine 下调试 PE: [[re-gdb]] ——
apt install gdb，验证gdb --version；Wine 直读：wine sample.exe后gdb -p <pid>attach（[[platform-tips]] Linux 分支） - Windows: [[re-x64dbg]] —— 官方 release zip，验证：载入样本能单步（attach 需管理员权限，[[platform-tips]] Windows 分支）
- macOS: [[re-lldb]]（
brew install lldb）；Windows 目标走 Wine + gdb 或 VM - 作用：断点确认成功 / 失败分支的真实走向，避免改错分支（见坑 2）
rizin（wx 写字节，命令行 patch 主力）
- Linux:
apt install rizin/dnf install rizin/pacman -S rizin；macOS:brew install rizin；Windows/WSL: WSL 内 Linux 包 - 验证:
rizin -v - 写字节语法:
wx 90 @ 0x401234（把 0x401234 处一个字节写成 0x90）、wx 909090 @ 0x401234（连写三个）
补丁文件工具（导出 diff / patch）
rz-diff（rizin 自带，二进制 diff 对比）/radiff2（radare2 自带，命令兼容）bsdiff/bspatch：Linuxapt install bsdiff/ macOSbrew install bsdiff，验证bsdiff -hxdelta3：Linuxapt install xdelta3，验证xdelta3 -V- Windows 侧：
llvm-objdump（LLVM 套件）对比原始字节段
操作步骤
按顺序执行，每步记录结果（原始字节 → 修改字节 → 偏移，证据路径见 [[re-triage]]）。修改前 cp sample.exe sample.bak 并 sha256sum 存档（见坑 1）。
- 定位 patch 点（失败跳转 → 改 jz / jnz）：
- 从 [[re-license]] 的校验点清单拿地址；反编译确认该点的指令形态：失败跳转（比较后
jz fail/jnz fail）是把校验失败当成立即跳走的分支 - 动态确认方向（沙箱内）：调试器断在该分支，输入错误序列号跑一次，观察跳转与标志位（[[re-gdb]] / [[re-x64dbg]]）——确认"改哪个条件、跳到哪里"才是绕过（见坑 2）
- 记录：patch 地址、原始字节、目标形态（如
jz 0x401300→nop）
- 从 [[re-license]] 的校验点清单拿地址；反编译确认该点的指令形态：失败跳转（比较后
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.

re-patching is a skill published in the GitHub repository dslsdzc/rev-skills (54 stars, last pushed 14d ago), licensed Apache-2.0. It adds 38 tokens to every session and 3,925 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.
