Android Reverse Engineering Skill
GitHub trending today: SimoneAvogadro/android-reverse-engineering-skill at 2,708 stars and +558 daily. It's a single Claude Code skill that turns Claude into an Android RE expert.
Feed it an APK, XAPK, JAR, or AAR. It decompiles with jadx (or Fernflower/Vineflower if you want), traces Retrofit endpoints, OkHttp calls, hardcoded URLs, authentication patterns, and walks the architecture layers. You can ask follow-ups in natural language. It also handles obfuscated code and manifest analysis.
This is the best example yet of why skills are the right primitive. The skill is just a markdown file plus prompt scaffolding. No new model, no new framework, no API. But it gives Claude a domain expertise level that previously required either a specialist tool or a senior reverse engineer.
Karpathy's skills repo hit 9,646 stars/day last week. Now this. The pattern is clear: vertical knowledge captured in skills format spreads faster than any framework. The unit of distribution is shrinking from product to plugin to single-file skill. The moat is the prompt, not the code.
