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

No annotations are supplied, so the description carries the full behavioral burden, yet it says nothing about default row count, the 50-row cap, tie-breaking, or what happens when the requested column is non-numeric. It also never states that this is a read-only operation over a fixed dataset, leaving that only to inference from the tool name and title.

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?

One compact sentence with no filler, front-loading the operation and resource. The trailing quoted example is slightly awkward as a sentence fragment, but it earns its place by illustrating the intent.

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?

This is a simple three-parameter query tool with no output schema, so the description does not need to explain return values. Still, for a ranking tool it omits the default result size and the numeric-column requirement's failure mode, which an agent needs to invoke it correctly.

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 coverage is 33% – only 'ascending' is documented in the schema, while 'column' and 'limit' are bare. The description usefully constrains 'column' to a numeric column, which the schema does not say, but it says nothing about the default or maximum value of 'limit', leaving one of three parameters unexplained in both places.

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 concrete operation on a specific resource: returning the highest (or lowest) rows of the Med Spa Cost Checker dataset ranked by a numeric column. The framing 'which is the most/least X' makes the intent immediately recognizable and distinguishes it from lookup-style siblings like dataset_row or dataset_search, though it never names those alternatives.

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 question framing ('which is the most/least X') implies the use case, which is helpful context for selection. However, there is no explicit statement of when to prefer this over dataset_stats or dataset_compare, and no exclusions or prerequisites given.

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