Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'testing-for-sensitive-data-exposure' ] || [ -L ~/.agents/skills/'testing-for-sensitive-data-exposure' ]; then echo 'A skill folder named testing-for-sensitive-data-exposure already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mukul975/Anthropic-Cybersecurity-Skills' "$d" && git -C "$d" checkout --quiet '54a798831d2266a3ca61ce68a7acb80b81160d57' -- 'skills/testing-for-sensitive-data-exposure' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/testing-for-sensitive-data-exposure' ~/.agents/skills/'testing-for-sensitive-data-exposure' && 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/'testing-for-sensitive-data-exposure' ~/.claude/skills/'testing-for-sensitive-data-exposure' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
