◇ Could this help me?
Yes, with the autonomy step qualified. The planner/executor split is the same verified advisor pattern as row 80 and genuinely stretches usage limits without giving up judgment quality, and /goal verifies as a real built-in Claude Code command (v2.1.139+) whose evaluator-checked completion condition is a disciplined way to define done. It is a general Claude Code technique, not project-specific; the one caveat is the final run-on-its-own step, which is unattended operation and should wait until sandboxing, scoped permissions, cost caps, and post-run review exist, per the same reasoning as rows 76 and 84.
Set up a model-tiering loop in Claude Code for a task I will describe. Configure an executor subagent that runs on a cheaper, faster model (Sonnet or Haiku) for the grunt work, while this session's top model writes the plan first and reviews the executor's output at the end, flagging anything that needs rework. Then propose a /goal completion condition for the task phrased as objectively verifiable criteria (tests pass, files under a size budget, checklist items done) so the loop continues until the work is actually finished. Keep all runs supervised in-session; do not set up any scheduled or unattended execution. The task is:
