+# Document Routing Agent
+
+An intelligent document routing system that automatically classifies and routes documents to appropriate departments based on content analysis, without using LLMs.
+
+## Overview
+
+This agent demonstrates the use of the UiPath LangChain SDK with deterministic rule-based routing. It analyzes document content, metadata, and patterns to make routing decisions with confidence scoring.
+
+## How It Works
+
+1. **Document Preparation**: Generates a unique routing ID and initializes processing
+2. **Content Analysis**: Scans document for keywords, document types, and patterns
+3. **Score Calculation**: Computes routing scores for each department based on:
+   - Keyword matches (up to 50 points)
+   - Document type matches (up to 30 points)
+   - Sender department alignment (up to 20 points)
+   - Tag matches (up to 10 points)
+4. **Routing Decision**: Selects the highest-scoring department with confidence assessment
+5. **Priority Assignment**: Calculates priority (0-100) based on urgency and department
+6. **Processing Time Estimation**: Provides estimated processing time based on priority
+
+## Routing Rules
+
+### Departments and Keywords
+
+- **HR**: employee, vacation, salary, benefits, leave, onboarding, performance, training
+- **Finance**: invoice, payment, budget, expense, revenue, tax, audit, financial
+- **Legal**: contract, agreement, compliance, legal, lawsuit, regulation, policy, terms
+- **IT**: software, hardware, system, network, security, database, server, technical
+- **Operations**: production, logistics, supply, inventory, quality, process, workflow, maintenance
+
+### Document Types
+
+Each department has preferred document types (e.g., Finance handles invoices, HR handles leave requests).
+
+## Agent Setup and Publishing
+
+
+1. **Set Up Python Environment**
+
+```bash
+# Install UV package manager
+pip install uv
+
+# Create and activate virtual environment
+uv venv -p 3.11 .venv
+
+# Windows
+.venv\Scripts\activate
+
+# Unix-like Systems
+source .venv/bin/activate
+
+# Install dependencies
+uv sync
+```
+
+2. **UiPath Authentication**
+
+```bash
+uipath auth
+```
+
+> **Note:** After successful authentication in the browser, select the tenant for publishing the agent package.
+
+```
+👇 Select tenant:
+  0: DefaultTenant
+  1: Tenant2
+  2: Tenant3
+...
+Select tenant: 2
+```
+
+3. **Package and Publish**
+
+```bash
+# Create and publish the package
+uipath pack
+uipath publish
+```
+
+Select the feed to publish your package:
+
+```
+👇 Select package feed:
+  0: Orchestrator Tenant Processes Feed
+  1: Orchestrator Folder1 Feed
+  2: Orchestrator Folder2 Feed
+  3: Orchestrator Personal Workspace Feed
+  ...
+Select feed number: 3
+```
+
+> Note: When publishing to personal workspace feed, the process will be auto-created for you.
+
+## Running Locally
+
+```bash
+# setup environment first, then run:
+uipath init
+uipath run agent --file ./test_cases/input/<name_of_your_test_case>.json
+```
+
+## Input Schema
+
+```json
+{
+    "document_id": "string",
+    "document_type": "string",
+    "title": "string",
+    "content": "string",
+    "sender_email": "string",
+    "sender_department": "string (optional)",
+    "urgency_level": "low|medium|high|critical",
+    "tags": ["array", "of", "strings"]
+}
+```
+
+## Output Schema
+
+```json
+{
+    "document_id": "string",
+    "routing_id": "string",
+    "assigned_department": "string",
+    "routing_confidence": "low|medium|high",
+    "priority_score": 0-100,
+    "routing_reasons": ["array", "of", "reasons"],
+    "secondary_departments": ["array", "of", "departments"],
+    "processing_timestamp": "ISO timestamp",
+    "estimated_processing_time": "string"
+}
+```
+
+## Test Cases
+
+The agent includes 5 deterministic test cases:
+
+1. **Finance Invoice**: High-urgency software license invoice → Routes to Finance
+2. **HR Leave Request**: Employee vacation request → Routes to HR
+3. **Legal Contract**: Critical service agreement amendment → Routes to Legal
+4. **IT Incident**: Critical database server outage → Routes to IT
+5. **Operations Work Order**: Low-priority maintenance request → Routes to Operations
