Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true and openWorldHint=false, so the read-only nature is covered. The description adds that prompts are 'task-specific' and 'ready-to-use,' which is mildly informative, but it does not disclose any additional behavioral traits such as error conditions, edge cases, or output format. It is consistent with the annotations, so no contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
