Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no parameters, no output schema, and no annotations, so the description must carry all context. It fails to explain what 'target files' are, how they are determined without parameters, or what the result of the extraction looks like, leaving significant gaps for an agent trying to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
