+- **`skipNextSpeakerCheck`** (boolean):

+- **`skipLoopDetection`** (boolean):
+  - **Description:** Disables all loop detection checks (streaming and LLM-based). Loop detection prevents infinite loops in AI responses but can generate false positives that interrupt legitimate workflows. Enable this option if you experience frequent false positive loop detection interruptions.
