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 but provides almost none. It does not explain where recordings are stored (memory, filesystem, or output), whether the operation blocks, what happens upon timeout, or the implications of the 'compatibility' designation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
