Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no parameters, annotations, or output schema, the description is the sole source of context. It explains the basic purpose but lacks details about the return format (e.g., board IDs, names), pagination, or any limitations. Given the simplicity of a zero-parameter read tool, this is minimally adequate but leaves gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
