Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'List' implies a read-only operation, but nothing discloses what 'services' are, what 'keywords' mean, whether data is cached or live, or what output shape to expect. The description adds almost nothing beyond the implication of the verb.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
