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. It discloses the scope (workspace exports directory) and ordering (newest first), but does not mention whether it returns file names, full paths, or includes subdirectories. It is honest but incomplete for a tool with no output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
