Is the Reverse Engineer Anything (REA) skill free?

Yes. The skill itself is free from morluto/rea. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Reverse Engineer Anything (REA)?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Reverse Engineer Anything (REA) with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Didn't pass
Tested: Jul 28, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · efc11e4

⚠ The author changed this skill after we tested it. The verdict below describes the version we ran on Jul 28, 2026; it's queued for a re-test.

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 28, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

The skill file copies in cleanly, but on its own it is inert - it only routes to 110 MCP tools that arrive with 'npx rea-agents setup', and REA's own doctor confirmed the rest is missing too: no Hopper, and Ghidra needs GHIDRA_INSTALL_DIR pointed at an extracted 12.1.2 release. The CLI underneath is real: pointed at Claude.app's app.asar it verified archive integrity and flagged a native binding whose declared SHA-256 did not match the file on disk, and I reproduced both hashes independently. It then refused to analyse further, and did the same on ChatGPT.app - two for two, because code-signed macOS Electron apps routinely carry unpacked native modules that no longer match the header, so a plain asar header parse got further than the skill did. Also worth knowing: the SKILL.md on GitHub declares 111 tools while the published CLI ships 110, a mismatch REA's own doctor is built to flag as drift.

What Reverse Engineer Anything (REA) does

A routing document that tells an agent which of REA's 110 reverse-engineering tools to reach for on a binary, an Electron ASAR, a managed PE assembly, an app package or a live browser page, and how to report findings as evidence with observations separated from inferences. It is a front end only: the analysis itself comes from the rea-agents CLI and MCP server, plus a Hopper or Ghidra backend for native targets.

How to install Reverse Engineer Anything (REA)

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
