What it does

This skill teaches an AI agent to use radare2, a command-line reverse engineering toolkit, to inspect compiled programs (such as exe, dll, so, elf and apk files) without a graphical interface. The agent follows a staged routine: first basic triage (file format, strings, imports, exports), then function listing, disassembly, cross-reference lookup and optionally patching a binary. It also ships a reconnaissance script that runs these checks in one go.

Great for

  • Security researchers or students learning static analysis of unknown executables
  • Developers who want a command-line workflow for inspecting binaries on Windows or Linux
  • Reverse engineers who want an agent to run routine radare2 triage and explain the output

Skip it if

  • Users who need a GUI or IDA/Hex-Rays style decompilation, since the skill is explicitly CLI-focused and points to other skills for those tasks
  • Analysis of web JavaScript, which the skill itself says belongs to a different skill
  • Modifying or running suspicious binaries without care: patching overwrites files and the skill describes dynamic debugging of samples, which can execute malware

Try asking

  • “Analyze this unknown exe with radare2 and tell me what it does”
  • “Find which function triggers the error string 'access denied' in this binary”
  • “Show me the imports of sample.dll and flag any networking or injection APIs”
  • “Compare old.exe and new.exe with radiff2 and summarize the changes”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Work on a copy of the sample and keep the original backed up before any patch step
  • Ask for triage first (file info, strings, imports) before requesting deep analysis, which the skill itself recommends
  • Run the bundled recon script for a quick overview, then ask for specific cheatsheet commands for follow-up
