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. While 'check' implies a non-destructive read-only operation, the description does not specify what the tool returns (e.g., boolean, status message), whether it executes an external command, or what 'available' precisely means. This leaves the agent uncertain about the tool's behavior and output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
