Reverse Engineer Anything: The Open-Source Tool That Turns Any Binary Into a Readable Spec (And Why Big Tech Won’t Love It)

Introduction

Every binary is a black box. Whether it’s a proprietary CLI tool, a firmware blob, or a legacy service, understanding what it does—and how to automate it—usually means hours of manual reverse engineering. For developers building AI agents, this is a bottleneck: agents need structured interfaces (APIs, schemas, command specs) to interact with the world, not opaque executables.

Enter BinSpec —an open-source tool that statically analyzes binaries and generates a readable specification: CLI flags, environment variables, input/output formats, and even a Python wrapper. It’s not magic; it combines static analysis (via LIEF and Capstone) with heuristics and optional dynamic tracing (via Intel PIN). The result is a machine-readable spec that an AI agent can consume to call the binary safely.

Big Tech won’t love it because it democratizes interoperability with closed systems.…
