Designing Production-Grade AI Agents: Fault Tolerance, Recovery, and Idempotency Patterns

This article presents a systematic approach to building reliable AI agents by classifying faults into API, tool, context, and control-flow layers, detailing detection mechanisms like repeat-call fingerprints and watchdogs, and outlining recovery strategies including exponential backoff, model cascade degradation, tool-error virtualization, and idempotent pre-check-confirm patterns to prevent death spirals and ensure safe retries.
