Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden and mostly does not. It discloses the conversion outcome (becomes an editable design) but says nothing about authentication, size/page limits, whether the import is synchronous, failure handling, or where the resulting design lands. For a mutation-style upload tool this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
