Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. 'Defer resurfacing' implies a mutation (snoozing), but it doesn't disclose permissions needed, whether the action is reversible, rate limits, or what happens to the node's state. It lacks details on effects like notifications or updates to due dates.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
