Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden of behavioral disclosure. It only states that the tool lists existing archives, but it does not clarify the numeric pattern (e.g., patch1.xp3, patch2.xp3), recursive behavior, handling of missing directories, or output format. The single sentence provides minimal insight into the tool's runtime behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
