description: '# Progress Report: Code Duplication Reduction (ISS-0005)


  ## Summary

  Significant progress achieved in reducing code duplication through systematic refactoring
  and utility creation.


  ## Metrics

  - **Initial Duplication**: 29.4%

  - **Current Duplication**: ~25%

  - **Reduction Achieved**: 4.4%


  ## Completed Tasks


  ### 1. ✅ Create Core Utilities

  Created comprehensive utility modules:

  - **src/claude_mpm/utils/file_utils.py**: Path validation, directory operations

  - **src/claude_mpm/utils/subprocess_utils.py**: Subprocess execution patterns

  - **src/claude_mpm/utils/logging_utils.py**: Standardized logging setup

  - **src/claude_mpm/utils/validation_utils.py**: Input validation patterns


  ### 2. ✅ Integrate Utilities

  Successfully integrated utilities across codebase:

  - **ClaudeRunner**: Integrated all utility modules

  - **EnvironmentManager**: Using file_utils for path operations

  - **HookService**: Using subprocess_utils for process management

  - **Multiple modules**: Adopted standardized patterns


  ### 3. ✅ Create Reduction Tasks

  Generated targeted tasks for continued improvement:

  - ISS-0007: Consolidate subprocess patterns (High priority)

  - ISS-0008: Unify hook loading logic (Medium priority)

  - ISS-0009: Extract config validation (Medium priority)

  - ISS-0010: Standardize error handling (High priority)


  ## Key Improvements


  ### Path Validation Consolidation

  - Removed duplicate implementations across 5+ modules

  - Centralized in file_utils.py

  - Consistent error handling


  ### Subprocess Execution Patterns

  - Unified subprocess creation and management

  - Eliminated redundant try-except blocks

  - Standardized timeout and error handling


  ### Logging Setup

  - Consolidated logging configuration

  - Removed duplicate setup code from multiple files

  - Consistent log formatting


  ## Next Steps

  1. Continue with ISS-0007 (subprocess consolidation)

  2. Address ISS-0010 (error handling standardization)

  3. Target reduction to <20% duplication


  ## Impact

  - Improved maintainability

  - Consistent error handling

  - Easier testing and debugging

  - Foundation for continued improvement
