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 discloses that it searches by name and column descriptions and returns matching objects and columns, which gives some insight into behavior. However, it does not specify whether the search is case-insensitive, if it supports wildcards, whether results are paginated, or any other behavioral traits. This is minimal disclosure for a search tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
