Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full behavioral disclosure burden. It only labels the tool as an 'expanded operation' and states the basic action, without disclosing side effects, required context (e.g., selected clips), or whether it mutates the project. This is insufficient for a creation operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
