Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of conveying behavior. It clearly signals a read operation ('Get') and adds meaningful context with 'active' and 'accumulated changes', implying no destructive side effects and that the tool returns state gathered over time. It does not explicitly say it avoids clearing watches, but nothing suggests mutation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
