Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but provides minimal behavioral information. It mentions the data source (OpenDART) and format (XML), but doesn't disclose important behavioral traits like whether this is a read-only operation, potential rate limits, authentication requirements, data freshness, or what happens when the XML file is unavailable. For a tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
