More skills make your AI agent smarter.

Mostly wrong. A team added skills so their agent could analyze documents. The bill climbed, answers slowed down, and the fix was to take skills away.

A team I worked with had built their agent the way most people do. Every time it learned to do something new, they wrote a skill for it. Read a contract. Summarize a policy. Pull the key dates out of a report. By the time I saw it, the agent had a shelf full of skills and it could do all of them. It was also slow, expensive, and quietly getting worse.
