 ### ⚠️ Agent Execution with Flow Control
-**Execution Model**: Uses action-planning-agent for synthesis generation with structured file loading.
+**Execution Model**: Uses conceptual-planning-agent for synthesis generation with structured file loading.
 
 **Rationale**:
 - **Autonomous Execution**: Agent independently loads and processes all required documents
 - **Flow Control**: Structured document loading ensures systematic analysis
 - **Complex Cognitive Analysis**: Leverages agent's analytical capabilities for cross-role synthesis
+- **Conceptual Focus**: Agent specializes in conceptual analysis and multi-perspective integration
 
-**Agent Responsibility**: All file reading and synthesis generation performed by action-planning-agent with FLOW_CONTROL instructions.
