Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure but offers minimal information. It states this is a read operation ('Get'), implying it's non-destructive, but doesn't describe what 'mount sessions' entail, potential side effects, authentication needs, rate limits, or return format. For a tool with zero annotation coverage, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
