Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior on its own. It says 'temporary', which hints at non-persistent effects, but it does not state whether the injected code is executed, whether it can disrupt a running server, whether cleanup occurs, or whether the operation is reversible. For a tool that injects arbitrary Pawn code, this lacks the safety-relevant behavioral detail an agent needs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
