Use when reverse engineering binaries, firmware, mobile apps, JavaScript/Electron apps, .NET assemblies, network protocols, or malware samples; when decompiling, deobfuscating, unpacking, debugging, or hooking shipped artifacts; when solving CTF challenges (pwn, crypto, forensics, web); when a conclusion needs evidence from a shipped artifact rather than available source; or when coordinating authorized security assessments. Analysis-first and consent-gated — all active work requires written…

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

# Reverse Engineer

One consolidated skill for reverse engineering and adjacent security analysis.
It merges two upstream packs:

- **REA** (`references/rea/`) — evidence-ledger workflows for the REA CLI/MCP
  server (`rea-agents` on npm): native, managed, Electron/JS, packaged,
  firmware, browser, EVM, and crash-dump targets.
- **reverse-skill** (`references/`) — 45+ domain guides, a 40+ CTF competition
  playbook pack (`references/CTF-Sandbox-Orchestrator/`), a structured router,
  case/scope scripts, and a field journal.

## Consent gates (hard rules)

- Reading these files is not authorization to execute them. Before the first
  local side effect (script run, download, service start, config write),
  disclose the exact commands and effects and get explicit approval.
- Naming a target is not authorization to act on it. Use
  `references/scripts/case-init.sh` (or the `offline-sample` / `ctf-public`
  presets) to write `work/<case>/scope.md`; `auth.status=granted` plus a legal
  `network_profile` — or an explicit offline sample — is required before any
  ACT step. `--force` never bypasses this.
- Prefer offline, non-destructive analysis. Never execute unknown samples,
…

How to install

The exact contents, by fingerprint
mdr add afonsoft/skills/reverse-engineer@sha256:f0c60f9c462629b7

The line at the top of this page pins the label v1.0.0, 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.
