android-reverse-engineering

android-reverse-engineering is a skill for Claude Code, Codex from SeaOf0/dsh-redteam-model. It costs 117 tokens per session (3,878 once invoked), scanned B, a copy of android-reverse-engineering, MIT.

A guide for examining Android app packages such as APK, XAPK, JAR, and AAR files by turning their compiled code back into readable code. It also traces network calls to identify web API endpoints and how app screens use them.

In plain words
What is it for?
Use it to decompile Android packages, compare decompiler results, find HTTP endpoints, and trace the path from an app screen to its network request.
Why use it?
It helps developers understand an Android app's code and network behaviour when the original source code is unavailable.

Installs and runs on its own, but its text points at files inside the plugin that ships it — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed.

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.

Security

Grade B, and why

android-reverse-engineering scanned grade B 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 4d ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/check-deps.ps1, scripts/check-deps.sh, scripts/decompile.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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Android Reverse Engineering

Decompile Android APK, XAPK, JAR, and AAR files using jadx and Fernflower/Vineflower, trace call flows through application code and libraries, and produce structured documentation of extracted APIs. Two decompiler engines are supported — jadx for broad Android coverage and Fernflower for higher-quality output on complex Java code — and can be used together for comparison.

Prerequisites

This skill requires Java JDK 17+ and jadx to be installed. Fernflower/Vineflower and dex2jar are optional but recommended for better decompilation quality. Run the dependency checker to verify:

bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/check-deps.sh

On Windows (PowerShell):

& "${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/check-deps.ps1"

If anything is missing, follow the installation instructions in ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/references/setup-guide.md.

Workflow

Phase 0: Fingerprint the App (recommended before anything else)

Before installing tools or decompiling, run a fast triage to determine what kind of app you are looking at. Decompiling Java is mostly useless for Flutter, React Native, Cordova/Capacitor, and Xamarin apps — the real code lives elsewhere. The fingerprint script tells you which.

bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/fingerprint.sh <file.apk|file.xapk>

It prints, in one screen:

  • Mobile framework (Flutter / React Native / Cordova / Xamarin / Native Kotlin / etc.) with the file marker that triggered the verdict.
  • HTTP stack (Retrofit, OkHttp, Ktor, Apollo, Volley) detected via DEX string scan — works even when class names are obfuscated.
  • DI / serialization signals (Hilt, Dagger, Koin, kotlinx.serialization, Moshi, Gson, Jackson).
  • Obfuscation level estimate based on root-level short-named packages.
  • Notable third-party SDKs (AppsFlyer, Datadog, Sentry, Firebase, payment SDKs, support/chat SDKs, etc.).
  • Consolidated native libraries across the base APK and all splits — XAPK split bundles often place .so files in config.<abi>.apk, not in base.apk.
  • Recommended next step, which differs by framework (e.g. for Flutter the script suggests blutter / strings libapp.so rather than jadx).

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.
