Overview
One 8 KB skill that replaces REA (Reverse Engineer Anything): plain CLI tools, no MCP. Benchmarked: 38% faster, 35% cheaper.
The project is written in Python and has 80 forks. It was created 5d ago.
What it is
leanrea is described as a single 8 KB skill file that replaces REA (Reverse Engineer Anything) using plain command-line tools rather than an MCP server.
Described capabilities
The description says it is 38% faster and 35% cheaper than REA, based on the project's own benchmarks. No benchmark method or dataset was supplied, so these figures are unverified. The README preview describes an electron mode that traces a feature through an app's app.asar file, and a native mode that inventories exports, checks TCC permissions, and checks single-instance locks. The preview is truncated. The classification label says mcp, which conflicts with the description's no-MCP design.
Getting started
No setup steps were supplied. Use the repository README to install the skill file and run its CLI tools.
git clone https://github.com/aicodeking/leanrea.git
cd leanrea
# see README for setupFrequently Asked Questions
Does it use MCP?
No. The description and README preview say it has no MCP server. The classification label says mcp, which conflicts with that.
How were the speed and cost figures measured?
The description gives 38% faster and 35% cheaper than REA. The benchmark method was not supplied.
What does electron mode do?
According to the README preview, it traces a feature from a native function to a main-process class to IPC channels in an Electron app's app.asar.
