Summary

Refactored tool execution in the Task Manager using the Command Pattern to improve maintainability, testability, and compliance with SOLID principles.

Key Changes

• Created a ToolExecutor interface defining a contract for all tool executors
• Implemented dedicated tool executor classes for each Task Manager operation
• Centralized error handling and response formatting
• Added consistent parameter validation across all tools
• Updated tool definitions with improved documentation

Benefits

• Better separation of concerns - each tool executor has a single responsibility
• Improved testability - tool executors are individually testable
• Enhanced maintainability - adding new tools requires less boilerplate
• Consistent error handling - standardized messages and validation
• Better developer experience - tool definitions now include references to their executors

Technical Details

• Implemented utility functions for common validation tasks
• Updated all tool executors to use standardized response formatting
• All tools now properly validate required parameters
• JSDoc documentation added to improve code comprehension
