Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It does disclose a key side effect ('begin its ingestion process') and a prerequisite (the memory must be pending in the Inbox), but it does not mention whether the action is irreversible, whether it removes the memory from the Inbox, or whether approval triggers asynchronous processing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
