Refactor: Modularize Task Master CLI into Modules Directory

Simplified the Task Master CLI by organizing code into modules within the scripts/modules/ directory.

Why:

• Better Organization: Code is now grouped by function (AI, commands, dependencies, tasks, UI, utilities).
• Easier to Maintain: Smaller modules are simpler to update and fix.
• Scalable: New features can be added more easily in a structured way.

What Changed:

• Moved code from single scripts/dev.js file into these new modules:
  • ai-services.js: AI interactions (Claude, Perplexity)
  • commands.js: CLI command definitions (Commander.js)
  • dependency-manager.js: Task dependency handling
  • task-manager.js: Core task operations (create, list, update, etc.)
  • ui.js: User interface elements (display, formatting)
  • utils.js: Utility functions and configuration
  • index.js: Exports all modules
• Replaced direct use of scripts/dev.js with the global task-master command (see dev_workflow.mdc).
• Updated documentation (dev_workflow.mdc) to reflect the new task-master command.

Benefits:

Code is now cleaner, easier to work with, and ready for future growth.

Use the task-master command (or npx task-master) to run the CLI. See dev_workflow.mdc for command details.

lgtm

[Crunchyman-ralph]

We should probably move these rules somewhere else, so that we can be compatible with other platforms, not just cursor.

We can do that after we implement MCP.

[eyaltoledano]

We can prob create the right rules based on the user's selections. we can do that with a command too. right now it get added via the npm package only

@eyaltoledano I'm going to let you merge this, but I'm about to push something on MCP, going to probably base myself off this branch, or else things will get too messy. Please merge as quick as possible

[eyaltoledano]

Holding this just a little longer while I get some integration tests defined for the modules
I'm not 1000% sure everything still works and ideally dont wanan push something broken

feat: Enhance Task Master CLI with Testing Framework, Perplexity AI Integration, and Refactored Core Logic

This commit introduces significant enhancements and refactoring to the Task Master CLI, focusing on adding and improving testing, new integration with Perplexity AI for research-backed task updates, and core logic refactoring for better maintainability and functionality.

Testing Infrastructure Setup:

• Implemented Jest as the primary testing framework, setting up a comprehensive testing environment.
• Added new test scripts to package.json including test, test:watch, and test:coverage for streamlined testing workflows.
• Integrated necessary devDependencies for testing, such as @types/jest, jest, jest-environment-node, mock-fs, and supertest, to support unit, integration, and end-to-end testing.

Dependency Updates:

• Updated package-lock.json and package.json to reflect the latest dependency versions, ensuring project stability and access to the newest features and security patches.
• Upgraded task-master-ai to version 0.9.16 and openai to 4.89.0.
• Added node_modules/@ampproject/remapping dependency (version 2.3.0) and updated @babel related dependencies to their latest versions.

Perplexity AI Integration for Research-Backed Updates:

• Introduced an option to leverage Perplexity AI for task updates, enabling research-backed enhancements to task details.
• Implemented logic to initialize a Perplexity AI client if the PERPLEXITY_API_KEY environment variable is available.
• Modified the updateTasks function to accept a useResearch parameter, allowing dynamic selection between Perplexity AI and Claude AI for task updates based on API key availability and user preference.
• Enhanced updateTasks to handle responses from Perplexity AI and update tasks accordingly, including improved error handling and logging for robust operation.

Core Logic Refactoring and Improvements:

• Refactored the isCircularDependency function to utilize task IDs instead of dependency IDs, ensuring consistency and clarity in dependency management.
• Implemented a new validateTaskDependencies function to rigorously check for both circular dependencies and self-dependencies within tasks, improving task relationship integrity.
• Enhanced UI elements in ui.js:
  • Refactored getStatusWithColor to incorporate icons for different task statuses and utilize a statusConfig object for color mapping, improving visual representation of task status.
  • Updated getComplexityWithColor to display colored complexity scores with emojis, providing a more intuitive and visually appealing representation of task complexity.
• Refactored the task data structure creation and validation process:
  • Updated the JSON Schema for tasks.json to reflect a more streamlined and efficient task structure.
  • Implemented Task Model Classes for better data modeling and type safety.
  • Improved File System Operations for task data management.
  • Developed robust Validation Functions and an Error Handling System to ensure data integrity and application stability.

Testing Guidelines Implementation:

• Implemented guidelines for writing testable code when developing new features, promoting a test-driven development approach.
• Added testing requirements and best practices for unit, integration, and edge case testing to ensure comprehensive test coverage.
• Updated the development workflow to mandate writing tests before proceeding with configuration and documentation updates, reinforcing the importance of testing throughout the development lifecycle.

This commit collectively enhances the Task Master CLI's reliability, functionality, and developer experience through improved testing practices, AI-powered research capabilities, and a more robust and maintainable codebase.

Gonna merge this and start working on the MCP server
