Agentic AI: the failure-mode catalog every team needs
Loops, hallucinated tools, infinite retries, prompt injection, schema drift. Name them, log them, and you'll spot them in production.
11 min · Reviewed 2026
The premise
Agent incidents fall into a small number of recurring shapes. A team that names them and logs against the names recognizes the next incident in minutes instead of days.
What AI does well here
Emit structured logs when given a logging tool
Follow a documented retry policy when given one
Surface unexpected tool errors instead of swallowing them
What AI cannot do
Recognize that it's stuck in its own loop
Distinguish prompt injection from legitimate user input
Diagnose its own root causes during an incident
