Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'ctf-forensics' ] || [ -L ~/.agents/skills/'ctf-forensics' ]; then echo 'A skill folder named ctf-forensics already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ljagiello/ctf-skills' "$d" && git -C "$d" checkout --quiet 'e79be2925d1612e8a97070d6201e300286672370' -- 'ctf-forensics' && mkdir -p ~/.agents/skills && cp -R "$d"/'ctf-forensics' ~/.agents/skills/'ctf-forensics' && 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/'ctf-forensics' ~/.claude/skills/'ctf-forensics' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
