Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and does well: it discloses the failure mode (`telemetry_consent` is null if Blender could not be reached), the outdated-addon remediation path, and that '(Premium)' sources don't consume the user's own API keys. It does not explicitly state read-only/no-side-effect behavior, which is the only notable omission.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
