Adding More Features to AI Agents Doesn't Make Them Smarter, Google Releases New Test Method

At a glance

Piling lots of features and instructions onto an AI agent does not necessarily make it perform better. Google has released an evaluation method to check whether features actually help, along with an open-source tool called 'Skill Lich'. This is because adding more features can lead to wrong tool calls and rising costs.

Key points

1. 1

   A skill is a bundle of instructions and procedures that helps an AI carry out a specific task.

2. 2

   An AI with a feature added and one without it are compared under the same conditions to check success rate, time, and token usage.

3. 3

   Even a high evaluation score may come from exploiting a system loophole, so security and accuracy are checked separately.

4. 4

   Skills whose performance gains have disappeared should be deleted, according to the explanation.

Why it matters

Companies need to confirm that features are truly effective and safe before using AI agents in real work.
