Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (arbitrary code execution with database modification risk), no annotations, and an output schema present, the description is complete. It covers purpose, behavior, warnings, and provides an example, addressing the need for guidance without repeating structured data. The output schema handles return values, so no additional explanation is required.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
