Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states 'Import all files' but does not disclose what happens if the folder is empty, if files are unsupported, or whether this operation is destructive. No mention of error handling, side effects, or required permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
