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

With no annotations provided, the description must carry the behavioral disclosure. It mentions both highest and lowest ordering via the phrase 'highest (or lowest)', hinting at the ascending parameter, but does not state default behavior, limit handling, or error conditions. It adds some context but lacks depth for a ranking operation.

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 redundancy. It efficiently conveys the core purpose without extraneous detail.

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?

The tool is relatively simple, but the description omits details such as default limit, handling of non-numeric columns, tie-breaking behavior, and output structure. Since there is no output schema and no annotations, these gaps make the description only minimally complete for an agent to call the tool correctly without further inference.

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 low (only ascending has a description). The description adds one meaningful constraint—'numeric column'—which clarifies the column parameter, but it does not explain limit bounds or default ordering beyond what the schema states. This does not sufficiently compensate for the sparse schema descriptions.

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 ranks rows by a numeric column, identifying the resource (LLC Lane dataset) and the operation (highest/lowest rows). It differentiates from siblings like dataset_search (which searches) and dataset_stats (which computes statistics) by focusing on top-N ranking.

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 use for 'which is the most/least X' but does not explicitly contrast with alternatives or state when not to use it. There is no mention of prerequisites (e.g., numeric column required) or exclusions, leaving usage context only implicit.

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