PRUDE
AI-Powered Message Triage & Workflow Automation System

OVERVIEW
Prude is an event-driven AI message triage system that processes incoming messages through AWS Bedrock for intelligent classification and summarization. The system routes messages to appropriate actions (reply, calendar, task creation) with human-in-the-loop feedback mechanisms and confidence scoring.
THE CHALLENGE
Processing high volumes of messages in real-time while maintaining accuracy and low latency. Initial implementation faced AWS Bedrock throttling issues (429 errors) under load, requiring sophisticated optimization strategies.
THE SOLUTION
Architecture
Built an event-driven architecture with the following components:
- Event-Driven Ingestion: Messages are ingested through EventBridge, enabling scalable and decoupled processing
- AI Classification & Summarization: AWS Bedrock powers intelligent message understanding and categorization
- Action Routing: Messages are automatically routed to appropriate actions (reply, calendar, task) based on classification
- Human-in-the-Loop: Feedback mechanisms allow users to correct and improve the system's accuracy
- Confidence Scoring: Each classification includes a confidence score for transparency and quality control
Performance Optimizations
During testing, uncovered AWS Bedrock throttling issues (429 errors) under high load. Implemented comprehensive solutions:
- Rate Limiting: Intelligent rate limiting to prevent API throttling
- Queueing: Message queueing system to handle bursts and maintain throughput
- Batching: Request batching to maximize API efficiency
- Redis Caching: Caching layer to reduce redundant API calls
- Lambda Warm Pools: Pre-warmed Lambda functions to eliminate cold starts
RESULTS
- Latency: Reduced from 2s to <400ms under 100× load
- Accuracy: Achieved ~95% classification accuracy
- Efficiency: Reduced manual triage workload by ~40%
- Reliability: Zero failed runs post-optimization
