Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds that the tool returns permissions and sizes, which is useful behavioral context. However, no annotations are provided, so the description carries full burden. It does not disclose whether this is a read-only operation (though presumably safe), whether it has side effects, or any performance implications (e.g., scanning large binaries). The description is minimal, leaving many behavioral aspects unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
