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.
