Install

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

if [ -e ~/.agents/skills/'testing-jwt-token-security' ] || [ -L ~/.agents/skills/'testing-jwt-token-security' ]; then echo 'A skill folder named testing-jwt-token-security already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/plurigrid/asi' "$d" && git -C "$d" checkout --quiet '293ce9f76e3abcd5ba18db284688bc0d9ac6691d' -- 'plugins/asi/skills/testing-jwt-token-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/asi/skills/testing-jwt-token-security' ~/.agents/skills/'testing-jwt-token-security' && 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-jwt-token-security' ~/.claude/skills/'testing-jwt-token-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
