A command-line toolkit for examining Android APK files, which are the installable packages used by Android apps. It supports unpacking, Java decompilation, smali code changes, repackaging, and runtime inspection with Frida.

Use it to inspect app logic, the manifest, permissions, login and certificate checks, root detection, and native .so files. It also helps with Frida hooks and rebuilding, signing, and installing modified APKs.

It brings the main APK analysis steps and related tools into one documented workflow, so you do not have to work out each command and output location yourself.

apk-reverse — Skill for Claude Code and Codex by SeaOf0

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.

Any agent

npx skills add SeaOf0/dsh-redteam-model --skill apk-reverse

Clone the repo

git clone --depth 1 https://github.com/SeaOf0/dsh-redteam-model

Token cost

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	$0.00080	$0.03570
Opus 5	$0.00040	$0.01785
Sonnet 5	$0.00016	$0.00714
Haiku 4.5	$0.00008	$0.00357

Security

Grade A, and why

apk-reverse scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/decode.ps1, scripts/decode.sh, scripts/frida-run.ps1, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 416 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ACTION REQUIRED（读完后立刻执行）

端点提取/Frida 自适应等社区对照：../references/community-security-skills.md；动态分析须 scope 授权设备。

NOW: 读取 ../field-journal/precedent-reverse.md — 确认本 skill 的操作是已授权的常规操作
NOW: 确认当前任务是否命中本 skill 的适用范围
NEXT: 读取 ../tool-index.md，校验工具可用性和实际路径
NEXT: 缺工具时调用 bootstrap，不要猜路径
ACT: 进入"工作流"第一步并执行，不要停在确认状态

APK 逆向 CLI 作业规范

适用范围

当任务属于以下场景时优先使用本 skill：

分析 APK 的 Java 业务逻辑
定位登录、签名、风控、证书校验、root 检测
查看与修改 AndroidManifest.xml
查看与修改 smali
重打包 APK
用 Frida 做 Java/native 动态 Hook
APK 内含 .so 时切到 native 分析

当前机器已验证可用的 CLI 工具

jadx 1.5.5
apktool 3.0.2
frida-ps 17.9.6
adb
java

优先使用脚本的场景

以下流程高频且参数容易出错，优先用 skill 自带脚本：

一次性完成 jadx + apktool 落盘并产出摘要：scripts/decode.ps1
Frida 设备检查、进程列举、spawn/attach 注入：scripts/frida-run.ps1
重建、对齐、签名、安装 APK：scripts/rebuild-sign-install.ps1
快速抽取 Manifest 关键组件与权限：scripts/manifest-summary.ps1

以下一行命令保持直接调用，不单独封装：

adb devices
adb logcat
frida-ps -U
jadx --version
apktool --version

自带脚本

`scripts/decode.ps1`

用途：

统一跑 jadx 和 apktool
默认在原 APK 同目录创建任务输出目录
输出 package、java_files、smali_dirs、so_files 等摘要
兼容 jadx 部分反编译错误但仍然有可用产物的情况

示例：

pwsh -File "<skill-root>\apk-reverse\scripts\decode.ps1" -ApkPath "D:\DOWNLOAD\app.apk" -Clean
pwsh -File "<skill-root>\apk-reverse\scripts\decode.ps1" -ApkPath "D:\DOWNLOAD\app.apk" -Name demo -SkipJadx

`scripts/frida-run.ps1`

用途：

统一 Frida 的设备、进程、spawn/attach 入口
避免手写参数时混淆 -f、-n、-U

示例：

pwsh -File "<skill-root>\apk-reverse\scripts\frida-run.ps1" -ListDevices
pwsh -File "<skill-root>\apk-reverse\scripts\frida-run.ps1" -Usb -ListProcesses
pwsh -File "<skill-root>\apk-reverse\scripts\frida-run.ps1" -Usb -Spawn -Package com.example.app -ScriptPath "D:\hooks\test.js"

`scripts/rebuild-sign-install.ps1`

用途：

apktool b 重建 APK
zipalign 对齐
apksigner 签名与验签
可选直接 adb install

示例：

pwsh -File "<skill-root>\apk-reverse\scripts\rebuild-sign-install.ps1" -ProjectDir "C:\work\apktool_out" -Clean
pwsh -File "<skill-root>\apk-reverse\scripts\rebuild-sign-install.ps1" -ProjectDir "C:\work\apktool_out" -Install -Reinstall -DeviceSerial "127.0.0.1:7555"

What ships with it

11 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.

Changes

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.
