Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has only two parameters and no output schema, but the description still falls short. It does not explain what kind of 'issues' are searched (e.g., by scope), how search results are returned, or any limitations. Given the rich set of sibling issue-related tools (create_issue, update_issue, list_issues), the description provides insufficient context for an agent to understand its unique role.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
