 # Self-Refining Resume Optimizer Agent
 
-An intelligent, multi-agent system built with **LangGraph**, **Llama 3**, and **Gradio** that autonomously refines resumes. Unlike standard tools, this agent scans for gaps, asks for human input, and iteratively critiques its own work until it hits a quality threshold.

 ## Project Overview
 
-This project implements a sophisticated **Agentic Workflow** that mimics a professional writer/editor relationship. It goes beyond simple text generation by introducing state management and user feedback loops.

 * **Gap Analysis:** Identifies exactly which skills (e.g., "SQL", "CI/CD") are missing from your profile.
 * **Human-in-the-Loop:** Pauses the workflow to ask you for context (e.g., *"You are missing SQL. Do you have this experience?"*) before writing.
 * **Self-Refinement:** A "Critic" node scores every draft (0-100). If the score is low, the "Writer" node must rewrite it.
+* **Professional Outputs:** Automatically generates a **tailored Cover Letter** and exports both documents as CSS-styled **PDFs**.
