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 but offers no information about what the tool does, its effects, permissions required, or any side effects. It fails to indicate whether this is a read, write, or other operation, leaving the agent with no behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
