Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits. It implies a read operation ('search'), but does not explicitly state it is read-only, nor does it mention rate limits, authentication, or side effects. The tool name suggests metadata is returned, but the description says 'search recordings', which is slightly ambiguous.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
