REA tops GitHub Trending: reverse-engineer any app from your agent
Past 50k stars and still climbing — plus three repos bolting onto Claude Code and Cursor: a token-cutting proxy, a model switcher, a security auditor.

Your coding agent, now a reverse-engineer
REA (“Reverse Engineer Anything”) is an MIT-licensed MCP server that wires Claude Code, Codex, Cursor or Gemini CLI into Ghidra, IDA, JADX and Binwalk — ask your agent to trace a binary, APK, Electron app or firmware image down to pseudocode, all locally. It’s #1 on GitHub Trending and past 50k stars; v4.1 (Oct 6) added Android APK and firmware analysis.
Cut the tokens your agent burns
headroom is a drop-in local proxy — `headroom wrap claude` — that compresses tool output, logs and RAG chunks before they hit the model: the repo clocks ~20% fewer tokens on coding agents and 60–95% on repetitive JSON, with originals cached locally so nothing’s lost and GSM8K accuracy unchanged. Apache-2.0, works with Claude Code, Cursor and aider.
One-click switching across every coding agent
cc-switch is an MIT desktop app (Tauri/Rust, ~139k stars) that manages API providers for Claude Code, Codex, Gemini CLI, Grok Build and more from one tray icon — 90+ presets plus local routing so you can run “GPT in Claude Code, Claude in Codex” with automatic failover. Install with `brew install --cask cc-switch`.
Turn your agent into a security auditor
Cloudflare open-sourced a coding-agent skill that runs a six-phase audit — recon, hunting, validation, independent record verification, reporting — and emits machine-readable, independently-verified findings to cut false positives. MIT; install with `npx skills add`. Needs an OS sandbox to safely run target-controlled code.
