Claude Opus 5.5 Powers Explosive Growth of REA Reverse Engineering Framework

Open-source reverse-engineering agent REA, integrated with Claude Opus 5.5, has surged to over 100,000 GitHub stars in six days, enabling developers to reconstruct commercial software features from binaries, compiled applications, and APIs without source code access. The toolkit, released in April but reaching viral adoption in October, bridges Anthropic's Model Context Protocol with professional decompilation engines like Ghidra, Hopper, and IDA, allowing agents to analyze native binaries, Electron apps, .NET assemblies, Android APKs, and websites.
