Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It accurately states that the tool lists all available audio transitions, which implies a read-only operation, but it does not disclose return format, whether a project must be open, or any other behavioral details. For a simple list operation, this is minimally adequate but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
