Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior. It only says 'detailed information' without specifying what that includes (e.g., volume, panning, devices). No mention of permissions, side effects, or response structure. This is insufficient for a mutation-free read tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
