Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds the useful fact that data comes from persistent memory and that the tool returns the current agent/task, which goes slightly beyond the tool name. However, with no annotations present, the description carries the full burden and does not mention read-only behavior, missing-data behavior, or possible side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
