Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits. It implies a read operation but does not explicitly state non-destructiveness, pagination behavior, rate limits, or whether the list is exhaustive. The statement 'list all tasks or filter by status' is insufficient to infer safety or performance characteristics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
