Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states the action ('scans') and scope ('recursive'), but doesn't describe what constitutes a crash dump (file extensions, formats), whether it requires permissions, rate limits, output format (though output schema exists), or error handling (e.g., invalid paths). For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
