Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover key behavioral traits: readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, indicating a safe, non-destructive, repeatable read operation with open-ended results. The description adds minimal value by specifying 'GET', which aligns with annotations but doesn't provide additional context like rate limits, authentication needs, or output format. No contradiction exists, but the description is redundant given the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
