69 / 100 · Review before installing
Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.
By agentydragon/ducktape (GitHub) · coding · 11 stars · scanned at commit 0f6c736
Systematic binary reverse engineering toolkit. Extract source code, understand functions, document protocols, compare versions. Uses strings, symbols, disassembly, and differential verification.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'reverse-engineer' ] || [ -L ~/.agents/skills/'reverse-engineer' ]; then echo 'A skill folder named reverse-engineer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/agentydragon/ducktape' "$d" && git -C "$d" checkout --quiet '0f6c7366e360008c0b067bcff173a088d6886981' -- 'devinfra/skills/reverse_engineer' && mkdir -p ~/.agents/skills && cp -R "$d"/'devinfra/skills/reverse_engineer' ~/.agents/skills/'reverse-engineer' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'reverse-engineer' ~/.claude/skills/'reverse-engineer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
