Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (single optional parameter, no output schema), the description provides the core purpose and one behavioral feature. However, it omits what the report contains (e.g., text, figures), possible response time, and any limitations. For a tool with no output schema, more detail on return format would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
