jadx

Quick Review

Excellent comprehensive skill for Android APK decompilation and security analysis. The description clearly articulates when to use jadx (decompiling APKs, finding vulnerabilities, analyzing app logic), making it easily invokable by a CLI agent. Task knowledge is exceptional with detailed command examples, systematic security search patterns, multiple workflow scenarios, and troubleshooting guidance covering basic to advanced use cases. Structure is very clear with logical sections progressing from basics to advanced features, though the single 400+ line file could theoretically be split into separate workflow files for even better organization. Novelty is strong: while jadx itself is a standard tool, orchestrating comprehensive security analysis—including systematic grep patterns for vulnerabilities, multi-tool integration strategies, and IoT-specific workflows—would require significant tokens and expertise from a raw CLI agent. The skill meaningfully reduces cost by codifying security analysis best practices and providing ready-to-use search patterns that would otherwise require security domain expertise to construct.
