agile-loop

Run the queued GSD → Superpowers → review → ship loop end-to-end. Reads tasks from `docs/agile-loop/tasks/*.md`, spawns isolated child sessions per stage, opens one PR per task, and auto-merges it (squash) before continuing to the next task. Use when asked to "run the agile loop", "process the next queued task", or "drive the autonomous engineering loop".
