Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a three-parameter mutation tool with no annotations, no output schema, and no parameter-level documentation, this description is too thin. It leaves out stack orientation, side effects, error handling, and return value, so an agent would have to infer critical invocation details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
