Harness Subagent · ptmrio bundle Use when the user asks to orchestrate, outsource, delegate, or hand off a slice to another coding-agent CLI as a one-shot subagent — Claude Code, Codex, Grok Build, Cursor Agent, Antigravity CLI, Gemini CLI, OpenCode, or Droid — or to ask Claude, ask GPT, ask Codex, ask Grok, ask Gemini, ask Fable, ask Astra, get a second opinion, or pressure-test a plan or diff from a different harness. Do not use to install those CLIs or to explain their flags. Do not use if this session was launched by this skill (prompt starts with YOU ARE THE WORKER, or HARNESS_SUBAGENT_RUN is set) — do the briefed job; do not spawn.
