Android APK reverse engineering: unpacking, Java decompilation, smali modification, repacking and signing, Frida dynamic hooking, and native .so analysis with jadx, apktool, adb, and related tools.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **⚠️ AUTHORIZED USE ONLY** > This skill is for educational purposes or authorized security assessments only. > You must have explicit, written permission from the system owner before using this tool. > Misuse of this tool is illegal and strictly prohibited. > **Mandatory confirmation gate** > Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target: > 1. Ask the user to state the exact target URL, IP, account, or resource. > 2. Ask the user to confirm written authorization and the permitted scope. > 3. Show the exact command(s) and explain their expected effect. > 4. Wait for explicit confirmation in the current conversation. > > Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab. ## When to Use - Analyzing or modifying an Android APK during an authorized assessment. - Hooking runtime behavior of an app you own or are cleared to test. ## 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 …

How to install
mdr add francostino/opencode-skills-collection/apk-reverse@sha256:bc34c43193fff338The line at the top of this page pins the label git:20260827.2a689f0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
