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 behavioral disclosure. 'Get profile by id' only indicates a read operation without detailing authentication needs, rate limits, error handling, or what the return format looks like (e.g., JSON structure). For a tool with no annotation coverage, this leaves critical behavioral traits unspecified, making it inadequate for safe and effective use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
