22 common failure modes identified in LLM agents

LLM agents, regardless of their specialization like coding or research, exhibit 22 consistent failure modes rather than unique bugs. These failures can be categorized, and specific prompts can mitigate them. The effectiveness of these prompts ranges from eliminating the failure entirely to merely flagging it, depending on whether the fix is a procedural rule for the model or a genuine improvement in its reasoning.
