Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint and non-destructive behavior, so the safety profile is covered. The description adds the returned content (package_slug, CPU/RAM/disk configuration), which is mildly useful given there is no output schema, but it discloses nothing about scope, pagination or provider context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
