Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple lookup tool with only two parameters and no output schema, the description is mostly adequate. However, the lack of annotations means the description should disclose more about the return value and matching semantics. The 'or throw' behavior is disclosed, but an agent cannot tell whether the result is a task object, a path, or a status message, nor whether the title match is exact or fuzzy. Given the tool's simplicity, this is a moderate gap rather than a severe one.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
