leanrea Cuts Reverse-Engineering Agent Overhead
leanrea is an 8 KB open-source skill that guides coding agents through reverse engineering with ordinary CLI tools instead of REA’s MCP server and 207 tool definitions. Its four-task benchmark reports 38% lower wall time, 35% lower cost, and 60% fewer tokens than REA across native binaries, Electron apps, Go binaries, and deep disassembly.
// ANALYSIS
leanrea makes a compelling case that better tool routing can outperform a heavyweight integration layer, though its benchmark is small and environment-dependent.
- –Uses tools such as `otool`, `nm`, `go version -m`, `jadx`, `apktool`, and `rg` directly through Bash
- –Reduces context overhead from REA’s 400.7k tokens to 34.5k tokens in the reported comparison
- –Covers Electron, Mach-O, ELF/PE, Go, Android, WASM, SQLite, pcaps, firmware, and web targets
- –The benchmark used one model, one Mac, and three repetitions per task, so broader validation is still needed
- –Results depend on having the relevant reverse-engineering utilities installed locally
