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 executes curl commands but doesn't mention safety considerations (e.g., potential for destructive operations, authentication needs, rate limits, or output format). For a tool that executes arbitrary curl commands, 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.
