Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavioral traits. It only states the action 'trigger a deployment' without clarifying whether the operation is synchronous or asynchronous, what permissions are required, or what the immediate outcome is (e.g., returns a deployment ID). This leaves significant behavioral ambiguity for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
