Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with no output schema, the description covers the main function and batch support. However, it lacks details on output structure, prerequisites (e.g., source must exist), language, and the exact meaning of 'guide' in the name. These gaps reduce completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
