Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with three required parameters, a nested 'updates' object, no output schema, and no annotations, the description is far too sparse. It does not explain return values, error handling, parameter structure, or any behavioral nuances, making the description incomplete for safe and correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
