# Phase 1: Foundation - Shared Utilities and Base Classes

## Description
Create the foundational shared utilities and base classes that will be used to reduce code duplication across the codebase.

## Scope
- CLI shared utilities (argument patterns, command base, error handling, output formatting)
- Service base classes (async, config, lifecycle, manager patterns)
- Core shared utilities (config loader, path resolver, singleton manager)

## Deliverables
- src/claude_mpm/cli/shared/ - Complete CLI utilities package
- src/claude_mpm/services/shared/ - Complete service base classes package  
- src/claude_mpm/core/shared/ - Complete core utilities package
- Comprehensive documentation and examples

## Status: COMPLETED ✅
All foundation components have been implemented and are ready for adoption.

## Files Created
- CLI Shared: argument_patterns.py, command_base.py, error_handling.py, output_formatters.py
- Service Shared: async_service_base.py, config_service_base.py, lifecycle_service_base.py, manager_base.py, service_factory.py
- Core Shared: config_loader.py, path_resolver.py, singleton_manager.py
- Example: refactored_config_example.py showing 50% code reduction

## Next Phase
Ready for Phase 2: CLI Command Migration
