Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Although the tool has no parameters and no output schema, it is a validation operation. The description lacks any indication of what the tool returns (e.g., boolean, errors, report) or how the result is communicated. An agent cannot fully understand the outcome of calling this tool, making the context incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
