Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. 'Wake/trigger an agent to start working' states the outcome but does not disclose whether the action is idempotent, what happens if the agent is already active, whether it is asynchronous, or what response the caller gets. This is a minimal outcome statement, not behavioral transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
