leanrea is an 8 KB skill file for coding agents that guides reverse engineering of compiled applications using ordinary command-line tools instead of an MCP server. It routes targets such as Electron and ASAR files, Mach-O binaries, native disassembly, Go binaries, Android APKs, WebAssembly, SQLite databases, network captures, firmware, and web applications to appropriate first commands; its procedures use strings, imports, extracted files, and call sequences to narrow the investigation. The skill also instructs agents to work on copies, batch shell probes, search hidden extracted directories, and label claims as seen, inferred, or unknown. It can be installed for supported agents with the skills CLI or manually by copying its plain-text SKILL.md file, and is MIT licensed. The repository reports a benchmark in which leanrea matched REA's accuracy with lower wall time, cost, turns, and token usage, while noting that the comparison used one model, one machine, and three repetitions per cell.

Gives coding agents a compact guide to inspecting compiled apps with ordinary command-line tools, routing each file type to a useful first command and narrowing the search through strings, imports, or extracted code — no MCP server needed. It also instructs the agent to distinguish findings from inferences.
