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

With no annotations, the description carries the entire behavioral burden and leaves key traits unstated: it never says the operation is a read-only top-N query, how ties are broken, what happens when the column is non-numeric, or what the default (and maximum) row count is. It does at least disclose the fixed dataset scope, implying no dataset-selection argument.

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 tight sentence: the action and the dataset come first, the directionality and column type follow, and the example question closes it. There is no filler or redundancy.

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 low-complexity three-parameter read tool, the core intent is covered, but with no output schema and no annotations the definition should still say what a returned row looks like and what the default limit is. Those gaps are moderate rather than disqualifying.

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 only 33% – only 'ascending' is documented there – so the description has to compensate. It adds the important constraint that 'column' must be numeric and mirrors the high/low directionality of 'ascending', but says nothing about 'limit' (default value, cap, or role), leaving one of three parameters unexplained everywhere.

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 gives a specific verb and resource: return the highest (or lowest) rows of the Insurance by Profession dataset ranked by a numeric column. The quoted example 'which is the most/least X' pins down the intended question shape, though it never names a sibling such as dataset_stats or dataset_search to disambiguate.

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?

Usage is conveyed indirectly through the example question pattern, which implies this is for extremal/'most-least' queries. There is no explicit statement of when not to use it, no mention of which alternative handles aggregates or plain lookups, and no prerequisites.

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