Install

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

if [ -e ~/.agents/skills/'signal-cli' ] || [ -L ~/.agents/skills/'signal-cli' ]; then echo 'A skill folder named signal-cli already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/javimosch/supercli' "$d" && git -C "$d" checkout --quiet '18c32f4b7197d246bdedcc9eca5d0403eaac0bc2' -- 'plugins/signal-cli/skills/quickstart' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/signal-cli/skills/quickstart' ~/.agents/skills/'signal-cli' && 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/'signal-cli' ~/.claude/skills/'signal-cli' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
