Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read tool with no output schema, the description provides the core purpose and type. However, it does not specify the return format or that it returns the current value. Given the high number of similar get_ siblings, a bit more context (e.g., 'returns current value as integer') would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
