ClassyShark is a standalone binary inspection tool for Android developers. It can reliably browse any Android executable and show important info such as class interfaces and members, dex counts and dependencies. ClassyShark supports multiple formats including libraries (.dex, .aar, .so), executables (.apk, .jar, .class) and all Android binary XMLs: AndroidManifest, resources, layouts etc.
To run, grab the latest JAR
and run java -jar ClassyShark.jar.

This repo is a Claude Code plugin marketplace. It
ships two agents — classyshark-headless (pure analysis) and classyshark-gui (drives the
live Swing window) — plus a get-started skill that tells Claude how to fetch the jar and pick
an agent.
Install (in Claude Code, or in a terminal):
# 1. Add this repo as a marketplace
claude plugin marketplace add github:android-security-engineer/android-classyshark-skills
# 2. Install the classyshark plugin
claude plugin install classyshark@android-classyshark-skills
# 3. Verify agents + skill are registered
claude plugin details classyshark@android-classyshark-skillsOr, interactively inside Claude Code: /plugin marketplace add github:android-security-engineer/android-classyshark-skills, then
/plugin install classyshark.
Then ask Claude to analyze a binary, e.g. "analyze this apk's methods and strings". Claude will obtain the jar (from the Releases / RELEASE.md) and drive ClassyShark through its JSON stdio protocol.
Marketplace layout:
.claude-plugin/marketplace.json # marketplace manifest (→ plugin ./classyshark)
classyshark/
.claude-plugin/plugin.json # plugin manifest (metadata only)
agents/classyshark-headless.md # auto-discovered agents
agents/classyshark-gui.md
skills/get-started/SKILL.md # auto-discovered skill
Validate locally: claude plugin validate . --strict and claude plugin validate classyshark --strict.
