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 mentions the tool lists reasons and its purpose for archiving, but doesn't add details like whether it's read-only, requires permissions, has rate limits, or what the return format is. It provides basic context but lacks rich behavioral traits beyond the minimal purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
