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 | $0.00040 | $0.02572 |
| Opus 5 | $0.00020 | $0.01286 |
| Sonnet 5 | $0.00008 | $0.00514 |
| Haiku 4.5 | $0.00004 | $0.00257 |
Grade A, and why
re-ios 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.

iOS 应用分析
何时使用 / 何时不用
- 用：拿到 IPA / 已安装 iOS 应用，需要看 Mach-O 结构、OC 类结构、代码签名、越狱环境动态分析
- 用：App Store 加密二进制需要脱壳
- 不用：目标只是 Mach-O 结构 / load commands（直接走 [[re-format-macho]]）
- 不用：需要运行时 hook / 绕过（走 [[re-frida]]）
- 不用：无越狱、无受管设备时的动态分析场景（静态先行，动态受限说明见坑 3）
工具准备
静态分析（解包 / class-dump / otool）可免沙箱；动态（越狱设备 / 模拟器 / 受管设备）按 [[platform-tips]] 最高原则在受控环境执行。
unzip / zipinfo —— ipa 解包
- Linux:
apt install unzip/dnf install unzip/pacman -S unzip - macOS: 自带 /usr/bin/unzip；Windows/WSL: WSL 内 Linux 版
- 验证:
unzip -v
class-dump —— OC 头文件导出
- macOS: 官方仓库 nygard/class-dump 最新 release 3.4 仅源码无预编译二进制——源码构建（xcodebuild）使用；
brew install class-dump公式已从 homebrew-core 下架（2026 实测 formulae.brew.sh 无此公式），不再可用 - 替代: class-dump-swift（mxms0/class-dump-swift）同样支持 OC 与 Swift 类/方法导出，源码构建（依赖 LLVM + make，非 Swift 工具链）——Swift 目标优先用它
- Linux/Windows: 无官方版；用 class-dump-swift 源码编译（依赖 LLVM + make，非 Swift 工具链），或在 macOS 虚拟机 / 远程 macOS 上执行
- 验证:
class-dump --help（输出 usage 即可）
otool —— Mach-O 结构 / 符号查看（Apple 自带）
- macOS:
xcode-select --install（Xcode Command Line Tools） - Linux 替代:
llvm-otool（apt install llvm/brew install llvm） - 验证:
otool -h /bin/ls
idevice 工具链（libimobiledevice）—— 设备识别 / 信息
- macOS:
brew install libimobiledevice（含 idevice_id / ideviceinfo / ideviceinstaller） - Linux:
apt install libimobiledevice-utils（Debian/Ubuntu）；Arch:pacman -S libimobiledevice - 验证:
idevice_id -l列出已连接设备 UDID；ideviceinfo输出设备型号/iOS 版本/UDID
越狱环境（可选）
- 越狱工具：unc0ver / checkra1n / palera1n（按设备型号与 iOS 版本选择），越狱后安装 OpenSSH + 包管理器（Sileo / Cydia）
- 验证:
ssh root@<设备IP>能登录 - 未越狱但需真机：Apple 开发者账号签名安装（免费账号签名 7 天有效，见坑 2）；越狱环境专项（tweak 开发/越狱检测）见 [[re-ios-jb]]
frida-ios-dump —— App Store 加密应用脱壳
- 前置：越狱设备 + frida-server（见 [[re-frida]] 工具准备）+ usbmuxd 转发
- 安装：
git clone https://github.com/AloneMonkey/frida-ios-dump && cd frida-ios-dump && pip install -r requirements.txt - macOS:
brew install libusbmuxd（原 usbmuxd 公式已改名，2026 实测）；Linux:apt install usbmuxd（Debian/Ubuntu，含 iproxy）；Arch:pacman -S libusbmuxd - 验证:
python3 dump.py -h（输出 usage 即可）；iproxy -h（转发工具可用性）
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 · 122 lines · 40 tokens per session scan A d9c17af2b5d0
re-ios is a skill published in the GitHub repository dslsdzc/rev-skills (54 stars, last pushed 14d ago), licensed Apache-2.0. It adds 40 tokens to every session and 2,572 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.
