Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'Remove member from workspace,' implying a destructive mutation, but doesn't specify whether this action is reversible, what permissions are required, or what happens to the member's data. For a deletion tool with zero annotation coverage, this is a significant gap in transparency about critical behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
