This example demonstrates how to create a specialized AI agent that provides legal information and guidance based on a knowledge base of legal documents. The Legal Consultant agent is designed to help users understand legal concepts, consequences, and procedures by leveraging a vector database of legal content. Key Features:
  • Legal Knowledge Base: Integrates with a PostgreSQL vector database containing legal documents and resources
  • Document Processing: Automatically ingests and indexes legal PDFs from authoritative sources (e.g., Department of Justice manuals)
  • Contextual Responses: Provides relevant legal information with proper citations and sources
  • Professional Disclaimers: Always clarifies that responses are for informational purposes only, not professional legal advice
  • Attorney Referrals: Recommends consulting licensed attorneys for specific legal situations
Use Cases:
  • Legal research and education
  • Understanding criminal penalties and consequences
  • Learning about legal procedures and requirements
  • Getting preliminary legal information before consulting professionals
