 ## ⚙️ **Execution Protocol**
 
-### ⚠️ Direct Execution Only
-**DO NOT use Task tool or delegate to any agent** - This is a document synthesis task using only Read/Write/Glob tools for aggregating existing analyses.
+### ⚠️ Direct Execution by Main Claude
+**Execution Model**: Main Claude directly executes this command without delegating to sub-agents.
+
+**Rationale**:
+- **Full Context Access**: Avoids context transmission loss that occurs with Task tool delegation
+- **Complex Cognitive Analysis**: Leverages main Claude's complete reasoning capabilities for cross-role synthesis
+- **Tool Usage**: Combines Read/Write/Glob tools with main Claude's analytical intelligence
+
+**DO NOT use Task tool** - Main Claude performs intelligent analysis directly while reading/writing files, ensuring no information loss from context passing.
