Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states it's a read operation without disclosing behavioral traits. It doesn't mention whether this is safe (non-destructive), what permissions are required, rate limits, error handling, or the format of returned data, leaving significant gaps for a tool with one complex parameter.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
