Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of disclosing side effects or behavior. The phrase 'test tool to check if MCP server is working' is vague and does not specify whether it performs any writes, makes network calls, or returns a simple status. This lack of detail fails to accurately convey the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
