feat: Enhance testing, CLI flag validation, and AI capabilities

This commit introduces several significant improvements: - **Enhanced Unit Testing:** Vastly improved unit tests for the module, covering core functions, edge cases, and error handling. Simplified test functions and comprehensive mocking were implemented for better isolation and reliability. Added new section to tests.mdc detailing reliable testing techniques. - **CLI Kebab-Case Flag Enforcement:** The CLI now enforces kebab-case for flags, providing helpful error messages when camelCase is used. This improves consistency and user experience. - **AI Enhancements:** - Enabled 128k token output for Claude 3.7 Sonnet by adding the header. - Added a new task to to document this change and its testing strategy. - Added unit tests to verify the Anthropic client configuration. - Added and utility functions. - **Improved Test Coverage:** Added tests for the new CLI flag validation logic.

+## Reliable Testing Techniques
+
+- **Create Simplified Test Functions**
+  - Create simplified versions of complex functions that focus only on core logic
+  - Remove file system operations, API calls, and other external dependencies
+  - Pass all dependencies as parameters to make testing easier
+  
+  ```javascript
+  // Original function (hard to test)
+  const setTaskStatus = async (taskId, newStatus) => {
+    const tasksPath = 'tasks/tasks.json';
+    const data = await readJSON(tasksPath);
+    // Update task status logic
+    await writeJSON(tasksPath, data);
+    return data;
+  };
+  
+  // Test-friendly simplified function (easy to test)
+  const testSetTaskStatus = (tasksData, taskIdInput, newStatus) => {
+    // Same core logic without file operations
+    // Update task status logic on provided tasksData object
+    return tasksData; // Return updated data for assertions
+  };
+  ```
+
+- **Avoid Real File System Operations**
+  - Never write to real files during tests
+  - Create test-specific versions of file operation functions
+  - Mock all file system operations including read, write, exists, etc.
+  - Verify function behavior using the in-memory data structures
+  
+  ```javascript
+  // Mock file operations
+  const mockReadJSON = jest.fn();
+  const mockWriteJSON = jest.fn();
+  
+  jest.mock('../../scripts/modules/utils.js', () => ({
+    readJSON: mockReadJSON,
+    writeJSON: mockWriteJSON,
+  }));
+  
+  test('should update task status correctly', () => {
+    // Setup mock data
+    const testData = JSON.parse(JSON.stringify(sampleTasks));
+    mockReadJSON.mockReturnValue(testData);
+    
+    // Call the function that would normally modify files
+    const result = testSetTaskStatus(testData, '1', 'done');
+    
+    // Assert on the in-memory data structure
+    expect(result.tasks[0].status).toBe('done');
+  });
+  ```
+
+- **Data Isolation Between Tests**
+  - Always create fresh copies of test data for each test
+  - Use `JSON.parse(JSON.stringify(original))` for deep cloning
+  - Reset all mocks before each test with `jest.clearAllMocks()`
+  - Avoid state that persists between tests
+  
+  ```javascript
+  beforeEach(() => {
+    jest.clearAllMocks();
+    // Deep clone the test data
+    testTasksData = JSON.parse(JSON.stringify(sampleTasks));
+  });
+  ```
+
+- **Test All Path Variations**
+  - Regular tasks and subtasks
+  - Single items and multiple items
+  - Success paths and error paths
+  - Edge cases (empty data, invalid inputs, etc.)
+  
+  ```javascript
+  // Multiple test cases covering different scenarios
+  test('should update regular task status', () => {
+    /* test implementation */
+  });
+  
+  test('should update subtask status', () => {
+    /* test implementation */
+  });
+  
+  test('should update multiple tasks when given comma-separated IDs', () => {
+    /* test implementation */
+  });
+  
+  test('should throw error for non-existent task ID', () => {
+    /* test implementation */
+  });
+  ```
+
+- **Stabilize Tests With Predictable Input/Output**
+  - Use consistent, predictable test fixtures
+  - Avoid random values or time-dependent data
+  - Make tests deterministic for reliable CI/CD
+  - Control all variables that might affect test outcomes
+  
+  ```javascript
+  // Use a specific known date instead of current date
+  const fixedDate = new Date('2023-01-01T12:00:00Z');
+  jest.spyOn(global, 'Date').mockImplementation(() => fixedDate);
+  ```
+
 See [tests/README.md](mdc:tests/README.md) for more details on the testing approach.

+# Task ID: 29
+# Title: Update Claude 3.7 Sonnet Integration with Beta Header for 128k Token Output
+# Status: done
+# Dependencies: None
+# Priority: medium
+# Description: Modify the ai-services.js file to include the beta header 'output-128k-2025-02-19' in Claude 3.7 Sonnet API requests to increase the maximum output token length to 128k tokens.
+# Details:
+The task involves updating the Claude 3.7 Sonnet integration in the ai-services.js file to take advantage of the new 128k token output capability. Specifically:
+
+1. Locate the Claude 3.7 Sonnet API request configuration in ai-services.js
+2. Add the beta header 'output-128k-2025-02-19' to the request headers
+3. Update any related configuration parameters that might need adjustment for the increased token limit
+4. Ensure that token counting and management logic is updated to account for the new 128k token output limit
+5. Update any documentation comments in the code to reflect the new capability
+6. Consider implementing a configuration option to enable/disable this feature, as it may be a beta feature subject to change
+7. Verify that the token management logic correctly handles the increased limit without causing unexpected behavior
+8. Ensure backward compatibility with existing code that might assume lower token limits
+
+The implementation should be clean and maintainable, with appropriate error handling for cases where the beta header might not be supported in the future.
+
+# Test Strategy:
+Testing should verify that the beta header is correctly included and that the system properly handles the increased token limit:
+
+1. Unit test: Verify that the API request to Claude 3.7 Sonnet includes the 'output-128k-2025-02-19' header
+2. Integration test: Make an actual API call to Claude 3.7 Sonnet with the beta header and confirm a successful response
+3. Test with a prompt designed to generate a very large response (>20k tokens but <128k tokens) and verify it completes successfully
+4. Test the token counting logic with mock responses of various sizes to ensure it correctly handles responses approaching the 128k limit
+5. Verify error handling by simulating API errors related to the beta header
+6. Test any configuration options for enabling/disabling the feature
+7. Performance test: Measure any impact on response time or system resources when handling very large responses
+8. Regression test: Ensure existing functionality using Claude 3.7 Sonnet continues to work as expected
+
+Document all test results, including any limitations or edge cases discovered during testing.
