At a glance

Runs a full workflow for authorized Android app security testing: static APK analysis, rooted emulator setup, traffic interception and Frida hook generation.

  • Setting up a rooted Android emulator for authorized app security testing
  • SKILL.md covers Purpose, Workflow, Usage and Outputs, plus 2 more sections
  • Runs Python scripts from its folder; calls python and adb
  • Statically analyzing an APK, XAPK or APKS bundle's manifest and permissions

What it does

The skill is built for authorized testing of Android apps packaged as a plain APK, an XAPK, or a split bundletool APKS archive. Five scripted phases carry it out: setting up an emulator with adb root and a pushed frida-server; extracting manifest metadata, permissions, DEX strings, native libraries and protection indicators; installing a plain, split or bundletool package; applying lab emulator property changes that must be reapplied after every cold boot since they live only in memory; and injecting a mitmproxy certificate into the system trust store to configure the device's proxy. A references file goes deeper into detection vectors, certificate injection and APK format differences.

A separate script generates Frida scripts for SSL-pinning tests, crypto logging and detection validation, and every run can produce an analysis JSON report, a manifest of the generated hooks, and optional mitmproxy capture output. Practical notes call for a dry run before changing an emulator, bundletool for APKS archives, system-level certificate injection since Android 7 and later usually ignores user-added certificates, and physical devices for targets that rely on hardware-backed attestation.

When your agent uses it

  • Setting up a rooted Android emulator for authorized app security testing
  • Statically analyzing an APK, XAPK or APKS bundle's manifest and permissions
  • Intercepting an app's network traffic with mitmproxy in a lab emulator
  • Generating Frida hooks to test SSL pinning or emulator detection in a lab

Example prompts

  • “Set up a Pixel emulator with Frida server for testing this APK.”
  • “Analyze this APK and list its permissions and native libraries.”
  • “Generate Frida hooks to test this app's SSL pinning in the lab emulator.”

Requirements

  • Python, to run the bundled scripts
  • Android SDK tooling and an emulator or rooted device
  • Frida and mitmproxy
  • bundletool.jar, for APKS archives

What it can do on your machine

Read from SKILL.md and the folder at commit ce2b65e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 6 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python
    • adb

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Android APK Pentester loads about 917 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 283 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~917
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 283 words (~917 tokens).

“Use this skill for authorized Android application security testing. It supports static APK/XAPK/APKS analysis, split APK installation, rooted emulator setup, traffic interception, and Frida hook generation for lab validation.”
