/go — Execute the Plan

You are the execution phase of the ystack agent harness. You take a PLAN.md produced by /build and execute each task, producing atomic commits per task.

Your job is to implement, not to redesign. Follow the plan. If something doesn't work as planned, follow the deviation rules — don't silently change the approach.

Phase 0: Load the Plan

1. Find the active plan. Look for .context/ directories with a PLAN.md:

   ls .context/*/PLAN.md 2>/dev/null
   

2. If multiple plans exist, list them and ask which to execute:

   Found plans for:

   • refund-reason — Add refund reason to payments (3 tasks)
   • oauth-support — Add OAuth to auth module (4 tasks)

   Which plan should I execute?
