+
+      This workflow is designed as a coordinated trio:
+      - `RUG` orchestrates decomposition, delegation, and validation loops.
+      - `SWE` executes implementation tasks.
+      - `QA` validates requirements, edge cases, and regressions.
+
+      Typical usage:
+      1. Start with `RUG` for multi-step tasks.
+      2. Let `RUG` delegate coding to `SWE`.
+      3. Let `RUG` delegate verification to `QA`.
+
+      Best results:
+      - Keep each delegated task narrowly scoped.
+      - Require explicit acceptance criteria per task.
+      - Run a final cross-task validation pass before completion.
