See a feature in an app that you want in your own product? Ask your agent to investigate it with REA. It can inspect the app without its source code, explain how the feature works, show the evidence, and build a version for your project.
REA connects your agent to tools for inspecting native binaries, JavaScript and Electron apps, .NET assemblies, and websites. You can also use the same tools from your terminal. Analysis runs locally, and results include the evidence and limitations behind each conclusion.
Setup registers REA with your agent and installs matching workflow instructions. Native analysis can use an existing Hopper or Ghidra installation; setup can optionally install Hopper with approval. Static JavaScript analysis needs neither engine.

## Quick start
### Set up your agent
With Node.js and npm installed, run:
 [code] 
Choose your agents, review the proposed changes, and approve them. Setup adds
REA's MCP server and matching workflow instructions, with backups of existing
configuration. Restart your agent afterward.
Setup supports Claude Code, Codex, Cursor, Gemini CLI, Grok Build and
other agents. See
installation and setup for provider configuration and
manual MCP registration.
### Ask your agent
 [code] 
Replace Notes with your target app and the feature you want to understand.
### Use the terminal
Inspect an extracted JavaScript/Electron app directory or ASAR:
 [code] 
The result includes modules, imports, Electron boundaries and their evidence.
Replace the path with your target, such as `"D:/apps/example"` on Windows.
To install the `rea` command for regular use:
 [code] 
For native analysis, configure a provider first. See the
CLI and Evidence guide for native commands, provider selection,
snapshots and scripting.
### Update REA
REA changes quickly, and new releases include frequent bug fixes. Keep your
installation up to date.
For an npm-installed CLI:
 [code] 
To refresh your agent registrations and skill, run the setup command printed
by the update.
If you use `npx`, update your agent setup with:
 [code] 
Review the setup changes and restart your agent. For one-off CLI commands,
use `npx rea-agents@latest` followed by the command.
## How REA works
Your agent calls REA through MCP to inspect the target and trace relevant code.
REA returns findings with their evidence. The agen
