Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple deletion tool with two parameters and no output schema, the description is mostly adequate. It states the resource (closed environment) and the mandatory flag. However, it lacks information about return values, error conditions, or whether the operation is reversible, which could be useful.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
