binary-re SKILL.md skillA

binary-re from 2389-research/binary-re is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add 2389-research/binary-re/binary-re@git:20260925.4c7cd80

Pins git:20260925.4c7cd80 in mdr.lock. Pin the fingerprint instead.

Analyzes ELF binaries, executables, and firmware images to understand behavior without source code; coordinates sub-skills binary-re:triage, binary-re:static-analysis, binary-re:dynamic-analysis, binary-re:synthesis, and binary-re:tool-setup. Use when working with a binary, executable, or ELF file; asked to reverse engineer, disassemble, decompile, or figure out what something does; targeting ARM64, ARMv7, x86_64, or MIPS; or analyzing Python bytecode (.pyc, marshal). For Python bytecode…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Binary Reverse Engineering

## Purpose

Comprehensive guide for binary reverse engineering. This skill provides the overall methodology, philosophy, and reference material. Related skills handle specific phases:

## Related Skills

| Skill | Purpose | Trigger Keywords |
|-------|---------|------------------|
| `binary-re:triage` | Fast fingerprinting | "what is this binary", "identify", "file type" |
| `binary-re:static-analysis` | r2 + Ghidra analysis | "disassemble", "decompile", "functions" |
| `binary-re:dynamic-analysis` | QEMU + GDB + Frida | "run", "execute", "debug", "trace" |
| `binary-re:synthesis` | Report generation | "summarize", "report", "document findings" |
| `binary-re:tool-setup` | Install tools | "install", "setup", "tool not found" |

**Note:** Each skill auto-detects based on keywords. You don't need to explicitly route - just ask what you need.

## Pre-Flight Verification

**Before beginning any analysis, verify tooling availability:**

### Core Tools (Required)
```bash
rabin2 -v  # Should show version
r2 -v      # Should show version
```

### Decompilation (Optional)
```bash
# Check r2ghidra availability
…

How to install

The exact contents, by fingerprint

mdr add 2389-research/binary-re/binary-re@sha256:e1e4c831b2faeac8

The line at the top of this page pins the label git:20260925.4c7cd80, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
