Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but reveals almost nothing about behavioral traits. It doesn't disclose whether this is a write operation (implied by 'create'), what permissions are needed, whether it's idempotent, how failures are handled in partial batches, or what the response format looks like. This is inadequate for a batch creation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
