Claude Code skill for Android APK reverse engineering — apktool, jadx, Frida workflows.
A skill bundle that teaches Claude how to do real Android reverse engineering: unpack APKs, decompile to Java with jadx, patch smali, hook with Frida. It chains the right tools instead of one-shotting jadx and giving up.
When to use: You need to inspect a Flutter/OkHttp app's traffic and pinning blocks Burp.
Prerequisites
Server/skill installed and authenticated — See repo README
Flow
Identify pinning
Decompile target.apk and find all references to TrustManager / CertificatePinner / Flutter's HttpClient.✓ Copied
→ List of hooks to patch
Patch + Frida
Generate a Frida script that no-ops checkServerTrusted across both Java and Flutter paths.✓ Copied
→ Frida .js + run command
Outcome: Working MITM channel on a test target you own.
Pitfalls
Reversing apps you don't have rights to is illegal in most jurisdictions. The skill assumes you've documented authorization. — Reversing apps you don't have rights to is illegal in most jurisdictions. The skill assumes you've documented authorization.

Troubleshooting
Common errors and fixes
apktool fails to unpack
Use the latest apktool (≥2.9). Older versions miss new resource tables.
Verify: apktool --version ≥ 2.9
repack signs but won't install
Use uber-apk-signer with --allow-resign and target the right SDK level.
