### **What's New**

#### **1. DE Pipeline Architecture**

* Redesigned DE from a single-coordinator agent architecture to a **pipeline-based architecture**.
* Enables more structured orchestration, clearer stage separation, and better flexibility.

#### **2. PII Anonymization Handling**

* Adjusted system prompt to ensure anonymized user inputs can still be correctly interpreted and processed by the DE.
* Improves robustness when PII masking or anonymization is applied upstream.

#### **3. Fix MoM agent name**

* Resolved issue where different coordinator agents had MoM sub-agents with the same name.
* Prevented incorrect MCP configs for MoM agents caused by them having the same name.

#### **4. Fix model config validation**

* Fixed model config validation logic to support model names containing '/'.
* Prevented incorrect model configs for agents.
