Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple no-parameter list operation, the description covers the essential purpose and scope (including groups, current values, ranges). However, it doesn't specify the return format or whether it returns all parameters at once, which could be useful given there is no output schema. Still, it's largely complete for this low-complexity tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
