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. It states it's a read operation ('Gets'), implying it's non-destructive, but doesn't cover other aspects like error conditions (e.g., if OBS isn't running), permissions needed, or what the return value looks like (e.g., boolean). This leaves significant gaps for a tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
