Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. The description 'Get shared context' gives no information about what the tool actually does behaviorally: what 'shared context' is, how it's retrieved, what permissions are needed, whether it's read-only or has side effects, what the return format looks like, or any error conditions. It's completely inadequate for a tool with parameters and no output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
