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 convey the key behaviors: selection of highest/lowest rows by a numeric column. However, it omits defaults (e.g., limit), tie-handling, and details about the returned rows, so significant gaps remain.

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 very brief and front-loaded with the core purpose. No words are wasted, though the 'Threewayly' reference could confuse agents expecting a generic dataset tool. Overall, it is efficient but not overly verbose.

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?

Given there is no output schema and no annotations, the description is too thin to fully support correct invocation. An agent cannot determine what happens when limit is omitted, whether full row objects are returned, or how to handle non-numeric columns. More behavioral and parameter context is needed.

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%, and the description adds only partial semantics: it clarifies the column must be numeric and hints at ascending/descending order. The limit parameter is completely unexplained, and the schema gives no description for column or limit. The description does not compensate for the low coverage.

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 title and description clearly state the tool ranks rows by a numeric column, returning the highest or lowest values. The 'which is the most/least X' phrasing gives a concrete semantic, and the tool is distinct 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?

No guidance is provided about when to use this tool versus alternatives such as dataset_stats or dataset_row. There is no mention of preferred use cases, exclusions, or relationships to sibling tools.

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