Launch an external model as a subagent for a second opinion, adversarial review, or delegated work. Default pathway is an agentic DeepSeek / Kimi / Zhipu GLM omp subagent (file/web/terminal tools, one process or fanned out N-wide); also Codex (GPT-5.5), Claude via the Agent tool, and Grok via omp (same x.ai token as the grok CLI). Use for independent root-cause analysis, cross-checking your reasoning, judge/jury panels, or handing implementation to a different model.
Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'subagent-launcher' ] || [ -L ~/.agents/skills/'subagent-launcher' ]; then echo 'A skill folder named subagent-launcher already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/peteromallet/Arnold' "$d" && git -C "$d" checkout --quiet '4815916805531030f062fc1c10bcc9f9cd10a40f' -- 'arnold_pipelines/megaplan/skills/subagent-launcher' && mkdir -p ~/.agents/skills && cp -R "$d"/'arnold_pipelines/megaplan/skills/subagent-launcher' ~/.agents/skills/'subagent-launcher' && 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/'subagent-launcher' ~/.claude/skills/'subagent-launcher' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
