Quick Start

Step 1. Install via PyPi

Install the latest version of Quark Engine:

$ pip3 install -U quark-engine

Step 2. Download Latest Rules

Fetch the latest rule database:

$ freshquark

Step 3. Run Summary Report

Analyze an APK with the downloaded rules and generate a summary report:

$ quark -a <apk_file> -s

Step 4. View Results

Example output: Screenshot-2025-11-25-22-36-54

Quark-Engine Skills

Quark-Engine also ships two Claude Code skills:

/quark:analysis — analyze an APK with Quark-Engine
/quark:rule-gen — generate a Quark rule from decompiled code

To install, run these commands inside Claude Code after installing Quark-Engine:

/plugin marketplace add ev-flow/quark-engine
/plugin install quark@quark-engine

The skills then should appear.
