Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For an export tool with no annotations and no output schema, the description is insufficient. It doesn't explain what 'cases data' includes, the export format (e.g., CSV, JSON), whether it's a bulk operation, or how results are delivered. Given the complexity implied by sibling tools and the lack of structured metadata, more detail is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
