Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00063 | $0.06290 |
| Opus 5 | $0.00032 | $0.03145 |
| Sonnet 5 | $0.00013 | $0.01258 |
| Haiku 4.5 | $0.00006 | $0.00629 |
Grade A, and why
re-hybrid-app 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.
How it starts
The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.
混合应用逆向（Flutter / React Native）
何时使用 / 何时不用
- 用：App 内发现 libflutter.so / libapp.so（Flutter）或 assets/index.android.bundle（React Native）
- 用：需要还原混合框架的业务逻辑（dart 快照 / JS bundle）
- 用：需要定位 JS↔原生桥接（MethodChannel / NativeModules）交换的敏感数据
- 不用：纯 Java/Kotlin 原生 App（走 [[re-apk]]）
- 不用：纯原生 so 逻辑（走 [[re-binary-core]]）
- 不用：需要运行时 hook——先静态定位再 [[re-frida]]
工具准备
静态分析可免沙箱（[[platform-tips]] 最高原则）；动态（reFlutter 重打包 / 运行）在受控设备 / 模拟器快照内。所有工具先验证再使用。
引擎识别 —— jadx / unzip（复用 [[re-apk]]）
unzip -l app.apk看 assets/ 与 lib/ 结构即可判引擎，跨 OS 安装见 [[re-apk]] 工具准备
blutter —— Flutter AOT 快照静态还原（libapp.so）
- 安装:
git clone https://github.com/worawit/blutter && cd blutter——C++20 项目，需较新编译器（g++>=13 / Clang>=16）+ cmake/ninja/pkg-config/libicu/libcapstone + pyelftools/requests- Debian/Ubuntu:
apt install python3-pyelftools python3-requests git cmake ninja-build build-essential pkg-config libicu-dev libcapstone-dev - Fedora:
dnf install gcc-c++ clang cmake ninja-build pkgconf-pkg-config libicu-devel capstone-devel python3-pyelftools python3-requests git - Arch:
pacman -S gcc cmake ninja pkgconf icu capstone python-pyelftools python-requests git - macOS:
brew install cmake ninja pkg-config icu4c capstone+pip3 install pyelftools requests
- Debian/Ubuntu:
- 用法:
python3 blutter.py libapp.so <输出目录>（自动检测 Dart 版本，必要时自动下载 Dart 源码编译引擎）——目前支持 Android arm64 libapp.so 与较新 Dart 版本 - 产物:
asm/（带符号反汇编）、objs.txt（对象池对象完整 dump）、pp.txt（对象池中所有 Dart 对象）、blutter_frida.js（Frida 脚本模板） - 验证: 输出目录出现
pp.txt且包含目标 App 类名
reFlutter —— Flutter 动态（重打包 + 流量截获）
- 安装:
pip3 install reflutter（Python 3，依赖 frida-tools） - 用法:
reflutter main.apk→ 输入 Burp 代理 IP → 产出release.RE.apk→ uber-apk-signer 重签（java -jar uber-apk-signer.jar --allowResign -a release.RE.apk）→ 安装运行 - 产物: 运行后
adb -d shell "cat /data/data/<包名>/dump.dart" > dump.dart（类/函数清单 + 代码偏移） - 验证:
reflutter -h输出版本与用法；重打包后能安装运行并产出 dump.dart - 注意: Flutter >= 3.24 需手动在设备上设置代理（
adb shell settings put global http_proxy <ip:port>）

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-hybrid-app is a skill published in the GitHub repository dslsdzc/rev-skills (52 stars, last pushed 13d ago), licensed Apache-2.0. It adds 63 tokens to every session and 6,290 once invoked, about $0.0003 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.
