Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries full burden. It only states the tool imports files into memory, implying a write operation, but does not disclose whether it overwrites existing data, appends, or checks for duplicates. Potential side effects like memory state changes or performance impacts are not mentioned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
