How I Built a Self-Verifying AI Agent with DynamoDB and ReAct Reasoning

Short summary

ChemSpectra Agent uses ReAct reasoning to autonomously call 5 FTIR analysis tools and detect self-contradictions, triggering automatic verification rounds—essential for regulated industries like pharma and forensics. DynamoDB stores audit trails with GSIs for compliance queries and atomic counters for safe concurrent metrics. Pattern shows how to turn 'AI that answers questions' into 'AI that verifies its work.'

• •ReAct agent selects from 5 tools autonomously; detects contradictions between outputs (e.g., 'PET identified but no ester groups found')
• •Verification loops run 2-4 iterations in <30s; confidence traces logged to DynamoDB for audit compliance
• •Production patterns: GSIs for time/material queries, atomic counters for concurrent safety, conditional writes for finalized reports

Generated with AI, which can make mistakes.
