Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the single parameter, lack of output schema, and the annotation contradiction, the description fails to provide complete context. It does not explain how market_name is used, what the generated output looks like, or how to interpret results. The read-only annotation is contradicted, further reducing completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
