A Practical Taxonomy for Handling Errors in Production LLM/Agent Systems
ByteByteGo·September 7, 2026
New
Summary
Distinguishes technical failures from semantic failures (malformed output, hallucination, wrong tool call) unique to probabilistic systems; covers fallback chains, circuit breakers, and idempotency requirements for tool-calling agents to avoid issues like double-charging on retry.
Why this signal
Directly applicable reliability-engineering reference for any production agentic system Thomas Engineering builds — semantic-failure handling in particular isn't covered by traditional exception handling.
