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 does mention that it 'verify[ies] the resulting state', which is a behavioral trait beyond a simple setter. However, it doesn't disclose side effects, permission requirements, error handling, or the format of the verified result. More transparency would be expected 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.
