Why AI agents struggle with too many tools

Researchers from Princeton and UC San Diego looked at how AI agents use specific instructions to complete tasks. They found that these skills help by creating a clear workflow for the computer to follow. It is about the process rather than adding new facts to the AI.

However, there is a catch. When the library of available skills gets too large, the AI struggles to pick the right ones. The agents get overwhelmed by the number of choices and start making mistakes.

This study shows that more is not always better for AI development. Designers need to focus on organizing these tools better so the agents can find what they need without getting confused.
