Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral transparency. It merely states the value range and default but omits any mention of side effects, safety profile (e.g., read-only nature), or required permissions. For a tool that likely just reads a register, it fails to explicitly confirm it is non-destructive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
