Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure. It implies a mutating operation ('remove') but provides no details: whether the operation is destructive, reversible, requires specific permissions, how the view is affected (e.g., shifting subsequent bytes), or what the return value is. This is a significant gap 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.
