The Complete Guide to LLM Agent Reliability in Production
Learn how to build AI agents that never fail silently, survive crashes, and maintain perfect state durability.

Introduction: The Reliability Gap
Most AI agents today are built as 'happy path' demos. In production, they encounter network timeouts, process crashes, and logical drift. This guide outlines the architecture needed to bridge the gap between a demo and a mission-critical agent.
The 7 Failure Modes of Production Agents
Understanding how agents fail is the first step to making them reliable. We categorize failures into Silent Completion, State Loss, Execution Timeouts, and Logical Drift...
The Role of the Reliability Layer
A reliability layer sits between your agent logic and the LLM API. Its job is to ensure that every decision is logged and every state change is durable...
