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. It states the tool lists meetings with filtering, implying a read-only operation, but doesn't address critical aspects like pagination (suggested by 'limit' parameter), rate limits, authentication requirements, or what happens if no meetings match. For a tool with 5 parameters and no annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
