REA
REA explained: evidence before imitation
Understand the local analysis bridge, supported targets and limits of its conclusions
What you will learn
- What REA connects
- Choose a target and surface
- Define authorization first
Before you start
- A target you own or are authorized to examine
- Node.js and npm
- A selected local provider only if native analysis is needed
Use a harmless artifact to test setup, provenance, limitations and cleanup
Key takeaways
- REA is a bridge between agents and local tools.
- Native and static JavaScript prerequisites differ.
- Authorization precedes technical access.
What REA connects
REA connects an AI agent to local analysis tools through MCP and offers equivalent CLI workflows. Its documented targets include native binaries, JavaScript and Electron applications, .NET assemblies and websites.
The useful output is an evidence-backed explanation of a feature, not a promise that an agent can reconstruct proprietary source. Each conclusion should retain the observation and limitation that led to it.
Choose a target and surface
A static JavaScript or Electron artifact can be inspected without a native analysis engine. Native binaries need a configured provider such as Ghidra, Hopper or IDA; browser observation is a different surface again.
The setup workflow may register MCP and install matching agent instructions. Those instructions guide the agent, while the actual capability depends on available local tools, target access and permissions.
Define authorization first
The project disclaimer confines use to lawful work on software you own or are authorized to examine. Possessing a file or being able to attach a debugger does not itself confer that authorization.
We inspected official files at commit `f75b1a4` and did not install REA, run a provider or analyze an app. Treat the following chapters as a source-guided evaluation, not a verified reproduction.
Decision guide
| Criterion | Option A | Option B |
|---|---|---|
| Best when | You need predictable behavior and easy auditing | You need adaptive optimization and have reliable telemetry |
| Main risk | May leave performance on the table | Can become difficult to explain or debug |
Implementation steps
- 1
Document the authorized target and question.
- 2
Select the relevant analysis surface.
- 3
Keep each claim linked to evidence and limitations.
Copy-ready example
authorized question -> local analysis surface -> evidence -> bounded conclusionFrequently asked questions
Is REA a decompiler by itself?
No. Native analysis depends on a configured local provider; REA exposes and coordinates its results.
Did we verify a feature reconstruction?
No. This series reviews pinned sources without running an analysis.
