What does REA connect?
The official repository describes REA as one MCP-based workflow for investigating application behavior, JavaScript and Electron applications, native binaries, and other artifacts. Its value is joining an agent's observations and tool calls into a traceable investigation. It does not turn an agent's explanation into proof: inspect the underlying evidence and keep the target within your authorization.
If you only need to inspect an extracted JavaScript application, begin there before adding native analysis engines. Native binary work has separate provider requirements and may take more setup.
A small first-use path
- Read the official installation guide for the current Node.js, npm, operating-system, and client requirements. The project changes quickly, so check the instructions again when you install.
- From a trusted directory outside the target project, run
npx rea-agents setup. Select only the agent client you intend to use. Review the proposed configuration paths, backups, and optional analysis engines before approving any change. Restart the client named in the setup result. - Choose a local sample that you have permission to analyze. For an extracted JavaScript or Electron application, the repository documents the one-off CLI form
npx -y rea-agents@latest analyze-javascript-application /absolute/path/to/app --json. Replace the example path, then read the reported modules, boundaries, evidence, and limitations before drawing a conclusion.
The commands above are upstream examples. We have not run them on a test fixture for this review. A package runner may download code; confirm the source and the changes the setup tool proposes before proceeding.
When do you need another analysis tool?
The README says static JavaScript analysis needs no native analysis engine. Native binary analysis can use an existing Hopper, Ghidra, IDA, or Kuna installation, configured for the target. Some Linux analysis paths also require a procps-compatible ps command for process ownership checks. Consult the installation guide for the current platform and provider matrix rather than assuming every feature works after the initial MCP registration.
If your agent does not show REA tools after setup, first inspect the setup report for the selected client and configuration path, then restart that client. A missing tool is not evidence that your target cannot be analyzed.
What would make a trial informative?
- Record the exact sample, its origin, the REA version, agent client, and available provider tools.
- Ask one narrow question whose answer you can independently check against the sample. Keep file and network permissions limited to that task.
- Separate observations, tool output, and the agent's interpretation. Note any unsupported claims or failed steps, not only a successful demonstration.
- Before adopting it for sensitive work, review configuration changes, logs, model-provider costs, and whether target data could leave your environment.
This is an evaluation checklist, not a claim that our team has completed the trial. GitHub stars and forks show attention; they do not validate analysis accuracy or safety.
