Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It states only that the tool gets a configuration, omitting details on error handling (e.g., missing ID), authentication requirements, or rate limits. This is insufficient for a safe and informed invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
