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 provides minimal information. It doesn't mention whether this is a read or write operation, what permissions are required, whether there are rate limits or quotas, what happens on partial failures, or what the typical response looks like. For a batch execution tool with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
