A Quick Guide to Agent Reverse-Engineering Skills, Picked by Goal

Let AI help you with reverse engineering, without building the toolkit from scratch: someone has laid out 10 reverse-engineering Skills and integration solutions for Agents, covering everything from unpacking Android installation packages and tracing frontend signatures to inspecting binaries and studying how a product was built. You can basically pick one by your goal. We have added all 10 to our site as Skill pages. Each page is written for the Agent to read, and includes trigger conditions, install commands, usage instructions, and boundaries.

First, a premise: reverse engineering is a double-edged tool. These Skills should only be used on your own targets, or on targets you have explicit authorization for (your own applications, CTF competitions, authorized security testing, research and learning). Several of the projects state this in their own disclaimers.

The whole picture in one table

Four categories by purpose

General purpose: when you don't know which tool to use

• REA connects analysis tools for native binaries, JavaScript and Electron apps, .NET assemblies and websites to the Agent, with evidence and limitations attached to every conclusion. It runs over MCP and is configured with npx rea-agents setup.
• reverse-skill works more like a triage desk: it first determines whether you have an APK, a binary, frontend encryption or a CTF challenge, then routes you to the matching method. Its workflow includes an authorization check, and it will not act on a target until the scope of authorization is written down. Other tools of this kind would do well to adopt this design.
• leanrea takes the opposite approach: no MCP at all, just an 8 KB instruction file that tells the Agent which local command to use for each type of target. In the author's own tests, it saved more time and cost than REA's MCP approach with comparable accuracy, but that is the author's self-testing: each item was run only 3 times, using a single model, so treat it as a reference.

By target: Android, frontend, binaries

• Android Reverse Engineering: first quickly determines which framework and network libraries the app uses and how heavily it is obfuscated, then decompiles and extracts interfaces. It can also restore the original Kotlin class names from R8-obfuscated code.
• JS Reverse Engineering Methodology (hello_js_reverse_skill): the focus is not on a particular tool but on "which layer the problem is in, and what evidence is enough to close it out," drawing conclusions through controlled experiments. It does not declare a license, so pay attention before use.
• JS Reverse Automation (js-reverse-automation): oriented toward engineering delivery. It lets the Agent find encryption functions in a real browser and generate callable JSRPC, Flask services and Burp configuration.
• Reverse Engineering Skill Set (reverse-skills): for IDA users. It hands exported decompilation results to the Agent to name symbols and restore structures, and also provides assistance for Frida, Unicorn and IDAPython.

Learning and competitions

• ctf-skills is split by question type. Once installed, when you work on a CTF the Agent pulls the matching approaches and tool lists for that type. If the competition has rules, first confirm whether AI is allowed.

All-in-one workspace and product analysis

• Open-ReverseLab is a knowledge base plus a toolbox, with 180-plus articles and 100-plus MCP tools, suited to people who want a complete workspace. It is GPL-3.0, so be mindful of copyleft obligations if you incorporate its contents into your own project. The repository includes exploit samples, and antivirus software may raise alerts.
• replica-skill is not reverse engineering in the traditional sense. It studies "what a product does": analyzing features and flows from public pages, app store listings and your own account, then moving through architecture, setup, testing, branding and launch. Its principle is to borrow only functionality, not copy the other party's code, logo, copy or content.

How to choose, without installing everything

A few practical suggestions:

• Studying a product's features: start with replica-skill.
• Looking at an Android app's interfaces: use Android Reverse Engineering.
• Tools already on your machine, want to avoid complex setup: use leanrea.

We would add a few more:

• Tracing frontend signatures: for methodology and rigorous verification, use hello_js_reverse_skill; for directly delivering callable services, use js-reverse-automation.
• Binary analysis with IDA: use reverse-skills.
• Doing CTFs: use ctf-skills.
• Not sure: install reverse-skill first and let it help you judge.

We don't recommend installing everything at once. Each additional Skill or MCP means the Agent carries another set of instructions; the more context they take up, the less room there is for actual work. And their authorization models, dependencies and licenses all differ.

A few things to know first

1. Authorization is the prerequisite. Only analyze targets that are yours or that you are authorized to analyze. These Skills are not meant for bypassing paywalls, access controls, or attacking live systems.
2. Licenses differ: MIT and Apache-2.0 are the most permissive; GPL-3.0 (Open-ReverseLab) is copyleft; hello_js_reverse_skill declares no license, which means by default no usage rights are granted, so it is best to contact the author before commercial use.
3. We have not run each one. Every Skill page is compiled from the project's own documentation and has not been tested on our side. Before installing, read its documentation and check the version.
4. Features change. These projects update quickly, and install commands and version requirements are authoritative only in the project's current README.
