Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (15 parameters, no annotations, but with output schema), the description is minimally adequate. It states the purpose, documents parameters (though redundantly), and mentions return format and error handling. However, for a query tool with many filtering options and sibling alternatives, it lacks guidance on when to use it, performance characteristics, and relationship to other tools in the system.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
