Aura AI Support Hub
An autonomous support agent utilizing LangGraph state machines, Pinecone RAG search, and human-in-the-loop checks.
Executive Overview
An autonomous support agent utilizing LangGraph state machines, Pinecone RAG search, and human-in-the-loop checks.
Business Problem
A support desk faced high ticket volumes, leading to long response times and increased support costs.
Client Goals
Technical Challenges
Avoiding agent hallucinations and managing chat state cycles while ensuring fast responses.
Solution
Designed and deployed an autonomous support agent. Built a cyclic LangGraph state machine. Integrated semantic search to ground responses in support docs.
Architecture Overview
Chat clients connect to a Python middleware API. LangGraph manages conversation state, querying Pinecone for context and invoking LLM endpoints.
Core Features
Technology Stack
API Integrations
Database Design
Pinecone stores vector embeddings. PostgreSQL manages active chat sessions and human logs.
Authentication Strategy
Session verification via secure cookies, with JWT authentication for administrative consoles.
Security Considerations
Enforces strict data access rules, filtering document search results by tenant identifier.
Performance Optimizations
Caches common query vectors in Redis, reducing vector database loads.
Testing Strategy
Unit tests run via pytest. Automated checks run queries against test documents to evaluate accuracy.
Deployment Strategy
Deploys as secure Docker containers to AWS ECS, using AWS Fargate serverless infrastructure.
Monitoring Strategy
LangSmith tracks agent paths and accuracy, alerting managers to anomalous responses.
Business Results & Lessons
Automated common support tickets, reduced response times, and lowered support costs.
Max-retry limits prevent agent loops. Human-in-the-loop gates are critical for high-risk actions.
Integrate multi-language translation tools. • Deploy sentiment analysis routing.
