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

With no annotations provided, the description carries the behavioral disclosure burden. It does state that the operation is numeric and can return either highest or lowest rows, which is useful. But it does not mention limit behavior, default ordering, tie handling, or return format.

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 with the core ranking behavior front-loaded. There is no filler or redundant restatement of the title.

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 ranking tool this is adequate but not complete: it conveys the operation and the numeric-column requirement, but since there is no output schema and no annotations, the description does not explain return values, default ordering, or limit semantics.

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?

Schema description coverage is only 33%, so the description needs to compensate. It clarifies that `column` must be numeric and links `ascending` to highest/lowest ordering, adding value beyond the schema. However, the `limit` parameter is not explained at all in the description.

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 that the tool returns the highest or lowest rows of the Sopvo dataset ranked by a numeric column, matching the title 'Rank rows by a numeric column'. It is specific about the resource and operation, though it does not explicitly distinguish itself from siblings like dataset_search or dataset_stats.

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 phrase 'which is the most/least X' implies the intended use case for top-N or bottom-N ranking questions. However, the description gives no explicit guidance about when to prefer this tool over siblings such as dataset_stats or dataset_search, and it does not mention any exclusions.

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