Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds behavioral context with 'governance filters and sanitization', but it does not disclose that the tool may auto-save memories based on triggers, as hinted by the input schema. Annotations only indicate readOnlyHint=false, so the side-effect profile remains vague.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
