Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility for behavioral disclosure. While 'Update' implies a mutation, the description doesn't specify what happens during the update (e.g., whether all fields must be provided, if partial updates are allowed, what permissions are required, or what the typical response looks like). This leaves significant gaps for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
