Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose the return shape ('matching pages with a text snippet'), which is genuinely useful, but says nothing about search semantics (exact vs full-text, language, stemming), result limits, or whether the snippet is truncated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
