Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It transparently explains that domain properties cover subdomains and describes how to filter by page, which adds useful behavioral nuance. However, it does not disclose safety traits (e.g., read-only), potential side effects, or rate limits, leaving some ambiguity for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
