Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility. It discloses what the tool returns: ticket names, prices, sale status, and remaining count. It implies a read-only operation with no side effects. While it doesn't mention authentication or rate limits, these are less critical for a simple lookup tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
