Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds the write/change nature ('[write, altera dados]') and bulk execution via ids, which goes slightly beyond the annotations (readOnlyHint=false). However, it does not disclose response behavior, side effects, permissions, partial-failure behavior, or edge cases, so transparency is basic rather than rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
