Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without any annotations, the description must disclose behavioral traits (e.g., side effects, output, limitations). It does none of this—'Premiere Pro expanded operation: encode file' reveals nothing about what the tool actually does, what it returns, or any side effects, constituting a complete lack of transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
