The specific ways agents go wrong and the habits that catch them early.
7 min · Reviewed 2026
The big idea
AI agents fail in predictable patterns: getting stuck in loops, taking the wrong action confidently, hallucinating tools they don't have, ignoring safety instructions when pressured. Knowing the common failure modes helps you build in checks before they bite you.
Some examples
Loops: agent keeps trying the same failing action — set a max-attempts limit.
Confident wrong actions: agent picks something plausible but incorrect — check work before commit.
Tool hallucination: agent uses a function that doesn't exist — limit to a defined toolset.
Goal drift: agent quietly switches to easier sub-goal — restate the real goal in checks.
