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

No annotations are provided, so the description carries the full burden. It clearly conveys a read-only ranking operation, but it does not disclose behavior around ties, non-numeric columns, default limit, or result ordering beyond the schema's ascending note. Core behavior is transparent, but edge-case behavior is not.

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, front-loaded sentence with no filler. The 'most/least X' paraphrase adds useful semantic context without bloating the definition.

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 description plus schema cover the core call requirements. However, there are no annotations, no output schema, and no usage exclusions, leaving minor gaps around expected return shape and when to prefer sibling tools.

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 should compensate. It adds the numeric-column constraint and implies ordering via 'highest/lowest', but it does not explain the limit parameter or its default, and the column parameter has no schema description. Compensation is partial at best.

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 states a specific verb-resource relationship: it ranks rows of the dataset by a numeric column and returns the highest or lowest. The 'most/least X' framing clearly distinguishes it from sibling tools like dataset_row, dataset_search, and 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 'which is the most/least X' phrase implies a clear use case, but the description gives no explicit when-to-use or when-not-to-use guidance and does not mention alternatives among the sibling tools. The usage context is implied rather than stated.

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