Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only says 'Remove a team member' without stating that this is a permanent deletion, that it may have irreversible consequences, or that specific permissions are required. For a destructive operation, this lack of disclosure is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
