Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states it's an update operation (implying mutation) but doesn't cover critical aspects like required permissions, whether updates are atomic or partial, error handling for invalid inputs, rate limits, or what the response contains. For a mutation tool with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
