Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
This is a simple listing tool with no parameters, no annotations, and no output schema, so one might argue the description is sufficient. However, the description doesn't explain what the returned data looks like (assessment names, run IDs, timestamps), what '最近运行编号' metadata means, or how it relates to anjian_get_assessment for follow-up retrieval. A list tool's value depends on what one does with the results, which is unstated.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
