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

With no annotations, the description carries the burden of behavioral disclosure. It does reveal that the tool sorts by a numeric column and can return either end of the ordering, but it does not mention default limit, tie handling, nulls, or the response shape. Useful but incomplete.

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 one crisp sentence with a clarifying example, and the key behavior is front-loaded. Slight redundancy with the title means it is not a 5, but there is no wasted prose.

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 three-parameter tool the core idea is present, and the schema covers limit bounds and ascending semantics. Still, without an output schema or annotations, the description omits usage boundaries and expected return ordering/defaults, leaving moderate gaps.

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 important meaning for 'column' by clarifying it must be numeric, and 'highest/lowest' aligns with the ascending flag. However, it does not explain limit behavior beyond schema bounds, and schema description coverage is only 33%, so the 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 names a specific operation — ranking rows by a numeric column and returning the highest or lowest — and grounds it with a concrete question ('which is the most/least X'). It is clear on its own, though it does not explicitly distinguish itself from siblings like dataset_stats or dataset_row.

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?

There is no explicit statement of when to use this tool versus alternatives such as dataset_stats, dataset_search, or dataset_row. The intended use is only implied by the 'most/least X' example, leaving an agent to infer when top-N ranking is the right choice.

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