+# Tool Implementation Refactoring Summary
+
+## Overview
+
+This refactoring converted all function-based tool implementations to class-based implementations that extend the `BaseTool` abstract class. This change provides a more consistent, maintainable, and extensible approach to implementing tools in the codebase.
+
+## Changes Made
+
+1. Converted the following tools from function-based to class-based implementations:
+
+    - `ApplyDiffTool`
+    - `InsertContentTool`
+    - `SearchAndReplaceTool`
+    - `UseMcpToolTool`
+    - `AccessMcpResourceTool`
+    - `AskFollowupQuestionTool`
+    - `SwitchModeTool`
+    - `AttemptCompletionTool`
+    - `NewTaskTool`
+    - `FetchInstructionsTool`
+
+2. Created or updated tests for the following tools:
+
+    - `ListFilesTool.test.ts`
+    - `SearchFilesTool.test.ts`
+    - `SwitchModeTool.test.ts`
+    - `AskFollowupQuestionTool.test.ts`
+
+3. Added documentation:
+    - Created `implementations/README.md` to document the class-based implementation approach
+
+## Benefits
+
+1. **Consistency**: All tools now follow the same implementation pattern, making the codebase more consistent and easier to understand.
+2. **Code Reuse**: Common functionality is now shared through the `BaseTool` abstract class, reducing code duplication.
+3. **Maintainability**: The class-based approach makes it easier to maintain and extend the tools.
+4. **Testability**: The class-based approach makes it easier to test the tools in isolation.
+5. **Type Safety**: The class-based approach provides better type safety and IDE support.
+
+## Future Improvements
+
+1. **Parameter Validation**: Add more robust validation for tool parameters using a schema-based approach.
+2. **Error Handling**: Improve error handling and reporting in tools.
+3. **Documentation**: Generate API documentation for tools automatically.
+4. **Tool Dependencies**: Allow tools to depend on other tools.
+5. **Tool Configuration**: Add support for tool-specific configuration.
+
+## Testing
+
+All tools have been tested to ensure they function correctly. The tests cover:
+
+1. Basic functionality
+2. Parameter validation
+3. Error handling
+4. Partial block handling
+
+## Conclusion
+
+This refactoring has significantly improved the structure and maintainability of the tool implementations in the codebase. The class-based approach provides a more consistent and extensible way to implement tools, making it easier to add new tools and maintain existing ones.
