Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Assign' implies a write operation, but it does not disclose effects (e.g., whether it overwrites existing assignments), permission requirements, or reversibility. The description is too sparse to convey behavioral traits beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
