Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no annotations, no output schema, and a sparse description, an agent lacks essential context for correct invocation and expectation-setting. The tool could modify a blog project, generate a report, or produce configuration, but nothing in the description clarifies this, making the definition incomplete for a tool with two parameters and no documented output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
