REA is real, and the hard boundary is visible.
REA 6.3.0 is an MIT-licensed npm package and public TypeScript repository. Its documented routes cover native binaries, JavaScript and Electron applications, websites, saved network captures, EVM bytecode, and recorded Linux crashes. Native work can use Hopper, Ghidra, or IDA. The exact provider and host requirements vary by target.[1][2]
The project does not present one model as a decompiler. It connects an agent to inspection tools, returns evidence, and lets the agent ask follow-up questions. That division matters. Ghidra still performs disassembly, decompilation, graphing, and scripting. The agent reads the outputs and builds an explanation.[4]
The upgrade is a shorter path to the instruments. It is not permission to skip instrument readings.
Four records keep the answer honest.
First, pin the target. Save the file hash, version, platform, architecture, and extraction route. A claim about one executable does not automatically apply to another release.
Second, retain the observation. Keep the instructions, strings, call references, loaded script, network capture, or runtime event that the tool returned. Third, write the inference as an inference. "This branch compares two command IDs" is different from "this branch implements the percentage rule."
Fourth, name an independent check. Compare a second input, inspect a neighboring path, read public source, or replay the behavior against the original. REA's own evidence workflow says static and runtime pattern matches are hypotheses rather than causal proof. It also says that a reconstruction check covers only the declared comparable claims, not global equivalence.[3]
Agent fluency creates a new review trap.
A polished answer can compress several uncertain moves into one smooth paragraph. It may jump from a decompiler's generated name to business intent. It may treat one successful input as the whole feature. It may forget that a running process has state the static artifact does not expose.
Ask the reviewer to point at each transition. Which target produced this output? Which bytes or events support the sentence? What remains unknown? Which second path could disprove the interpretation? If the answer cannot survive those four questions, more fluent prose will not fix it.
Installation is a separate decision.
The public setup route can register an MCP server and workflow instructions with supported coding agents. Native analysis may also use an existing Hopper, Ghidra, or IDA installation. That is configuration work, not a read-only demo.[1]
For this dispatch, the repository was cloned at revision b25922e4e8fe389cf17c151ccb7b4be4a42824d9. The installer was read as text and its help path was run. The installer script resolves a release, checks Node.js and npm, installs the npm package globally, verifies the installed version, and may start setup when a terminal is available. It was not executed as an installer. No agent configuration, analysis engine, account, or target application was changed.
Keep authorization in the packet.
Technical access is not the same as authorization. The project's disclaimer puts lawful use and required permission on the user.[2] Put the owner, allowed target, allowed actions, retention rule, and stop condition beside the technical question. A tool that can inspect more kinds of software needs a clearer intake gate, not a vaguer one.
