Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions what the tool does but doesn't describe important behavioral aspects: whether it reads files safely, handles large files, returns errors for missing files, provides output format, or has performance characteristics. 'Verify file integrity' hints at comparison but doesn't explain how verification works.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
