AI Task Manager Agent

AI Task Manager Agent is a conversational task-management assistant that turns natural-language requests into structured, persisted tasks rather than saving raw messages as titles. A message like 'I have to submit my final project tomorrow' is cleaned of filler phrases such as 'I have to,' 'remind me to,' or 'please,' and converted into a clear task title with an inferred priority and optional due date. The agent follows a strict state-machine workflow — plan, action, observation, output — and is restricted to a whitelist of approved functions (saveTask, getTasks, completeTask, deleteTask), with loop detection and a five-iteration cap to prevent runaway reasoning cycles. Malformed LLM output is automatically repaired, handling invalid JSON, escaped quotes, unicode issues, and stray markdown code fences before parsing. The system prevents duplicate pending tasks, supports fuzzy, case-insensitive matching so users can complete or delete tasks without typing exact titles, and groups results into a pending/completed dashboard view with emoji-coded priorities. Tasks are persisted in MongoDB with title, priority, status, due date, and timestamp fields, so state survives restarts and remains available across sessions.
