Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'offensive-crypto-attacks' ] || [ -L ~/.agents/skills/'offensive-crypto-attacks' ]; then echo 'A skill folder named offensive-crypto-attacks already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/SnailSploit/Claude-Red' "$d" && git -C "$d" checkout --quiet 'a8de813edc9f66f60d44cfe42d47750e89d9930b' -- 'Skills/crypto/offensive-crypto-attacks' && mkdir -p ~/.agents/skills && cp -R "$d"/'Skills/crypto/offensive-crypto-attacks' ~/.agents/skills/'offensive-crypto-attacks' && 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/'offensive-crypto-attacks' ~/.claude/skills/'offensive-crypto-attacks' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
