Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility for behavioral disclosure. It states 'Remove team member' implying a destructive mutation, but provides no details on side effects, required permissions, reversibility, or what 'legacy' means in terms of behavior differences.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
