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 this is an update operation (implying mutation), but doesn't disclose any behavioral traits such as required permissions, whether changes are reversible, error conditions, or what happens to unspecified fields. 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.
