Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It describes the tool's behavior as checking index readiness, which is clear but minimal. It doesn't disclose additional traits like what 'ready' means operationally, potential latency, error conditions, or return format. For a tool with zero annotation coverage, this leaves gaps in behavioral understanding, though the core function is stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
