Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden, and it does convey the core behavior: selecting rows by top/bottom numeric ranking. However, it leaves key behavioral details unstated, such as whether full rows are returned, how ties or nulls are handled, and whether the operation is strictly read-only.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single compact sentence that front-loads the core ranking purpose and adds a clarifying 'which is the most/least X' gloss. There is no filler or redundant restatement of the tool name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple ranked-rows tool, the description plus schema provides the minimum needed to make a call: the numeric column, optional limit, and ordering flag are present. But there is no output schema, no default-limit information, and no discussion of return shape or edge cases, so the agent is left with assumptions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds useful meaning by specifying that the column must be numeric and that highest/lowest ordering is the operation, complementing the sparse schema (only 'ascending' has a description). It does not explain the 'limit' parameter beyond its name, and overall schema coverage is only 33%, so compensation is partial.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns the highest or lowest rows of the Csatzo dataset based on a numeric column, and the title adds the 'rank rows' framing. It does not explicitly differentiate itself from sibling tools like dataset_stats or dataset_search, so it misses the top criterion for a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies a use case — finding the most/least X — but gives no explicit guidance on when to choose this over dataset_row, dataset_search, or dataset_stats. There are no exclusions, prerequisites, or alternative tool mentions, so an agent must infer the boundary from sibling names.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
