 ### Planning & Task Creation Process
 The command performs structured planning and task creation:
 
-**0. Pre-Planning Architecture Analysis** ⚠️ FIRST STEP
-- **System Structure Analysis**: Run `bash(~/.claude/scripts/get_modules_by_depth.sh)` to discover project hierarchy
+**0. Pre-Planning Architecture Analysis** ⚠️ MANDATORY FIRST STEP
+- **System Structure Analysis**: MUST run `bash(~/.claude/scripts/get_modules_by_depth.sh)` for dynamic task decomposition
 - **Module Boundary Identification**: Understand module organization and dependencies
 - **Architecture Pattern Recognition**: Identify architectural styles and design patterns
 - **Foundation for documentation**: Use structure analysis to guide task decomposition

 **rg (ripgrep)**: Fast content search with regex support
 **find**: File/directory location by name patterns
 **grep**: Built-in pattern matching in files
+**get_modules_by_depth.sh**: Program architecture analysis and structural discovery
 
 ### Decision Principles
 - **Use rg for content** - Fastest for searching within files
 - **Use find for files** - Locate files/directories by name
 - **Use grep sparingly** - Only when rg unavailable
+- **Use get_modules_by_depth.sh first** - MANDATORY for program architecture analysis before planning
