Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the effect ('aggressive parallel-style compressor') but does not explain whether the operation is destructive, how it modifies the track, or what the result will be. Furthermore, the assertion 'No params — preset values' directly contradicts the input schema which includes a required track_id, undermining trust in the description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
