Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations include readOnlyHint: true, which implies no side effects. The description adds that it accepts free-text property type and optionally a country, which are inputs but not behavioral traits. It doesn't disclose anything beyond the schema and annotations—like whether it returns a single plan or multiple options, or whether it's a recommendation engine vs. a static lookup. Since annotations cover the safety aspect (read-only), the description doesn't need to repeat that, but it could add value by mentioning how recommendations are generated (e.g., based on property type and room count) or that it returns a set of guides. The score is adequate but could be higher with more behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
