Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It only states 'assign', which implies a mutation, but fails to mention required permissions, side effects (e.g., overwriting existing assignments), reversibility, or any other behavioral traits. This is a significant omission.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
