Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool with annotations and an output schema, the description is nearly complete—it covers scope, languages, and return pattern. The only gap is lack of differentiation from the sibling tool 'search_content', but this is a minor omission.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
