A Threads post comparing REA (morluto/rea) with a lightweight alternative called leanrea. It explains that REA is an MCP server plus skill bundling 170+ tools with Hopper/Ghidra/IDA decompiler integrations, installed via npx rea-agents setup, while leanrea replaces this with plain CLI commands in an 8KB skill. It cites official benchmarks on Sonnet showing leanrea is 38% faster and 35% cheaper (388s/$2.17 vs 627s/$3.36) with 56% fewer turns and 60% fewer tokens, at nearly equal accuracy (74/75 vs 75/75).
