Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
readOnlyHint=true already declares the safety profile. The description adds genuine context beyond annotations: the workspace/team naming discrepancy, the fact that returned ids are the team_id parameter used elsewhere, and the underlying REST endpoint. It does not mention auth scope requirements or empty-result behavior, keeping it short of a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
