 ### Task Decomposition Standards
 
+**Core Principle: Task Merging Over Decomposition**
+- **Merge Rule**: Tasks that can be executed together should not be separated - avoid unnecessary decomposition
+- **Decomposition Criteria**: Only decompose tasks in the following situations:
+  - **Excessive Workload**: Code exceeds 2500 lines or modifies more than 6 files 
+  - **Context Separation**: Involves completely different tech stacks or business domains
+  - **Dependency Blocking**: Subsequent tasks must wait for prerequisite task completion
+  - **Parallel Execution**: Independent features that can be developed simultaneously by different developers
+
 **Rules**:
 - **Maximum 10 tasks**: Hard limit - exceeding requires re-scoping
 - **Function-based**: Complete functional units with related files (logic + UI + tests + config)
