Background

One issue I have seen while experimenting with AutoGPT is that it will go deep down irrelevant rabbit holes. In order to address this I am experimenting with having a more structured way of organizing tasks.

Changes

• TaskManager: A singleton class responsible for managing tasks, including creating tasks, retrieving tasks by ID, updating task states, and displaying task hierarchy.
• TaskState:An enumeration representing the state of a task (NOT_STARTED, IN_PROGRESS, COMPLETED).
• Task: A class representing individual tasks with properties like ID, name, state, parent task, and subtasks.
• New --taskmanager command line flag to enable and disable
• New commands for managing tasks: update_task_state and set_current_task

Test Plan

• Add unit tests for Task Manager, Task, and TaskState

Outstanding items

• Refine prompt to ensure AutoGPT is always managing tasks
• Allow for programmatically adding task manager portion of prompt based off command line flag

Change Safety

• I have added tests to cover my changes
• I have considered potential risks and mitigations for my changes
