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. It implies a read-only ranked listing but says nothing about the default number of rows returned, the ordering guarantee, whether ties are broken deterministically, or how the result is shaped — all relevant for a ranking tool with zero annotation coverage.

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?

A single front-loaded sentence that leads with the operation and appends a useful query-shaped paraphrase; nothing is wasted. The nested quotation is slightly awkward but does not impede comprehension.

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 three-parameter, single-dataset ranking tool with no output schema and no annotations, the description covers the core intent adequately but omits return shape and default-row behavior. Those omissions are the main things an agent would still need to guess at.

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% (only 'ascending' is documented in the schema), but the description partially compensates by conveying that 'ascending' selects lowest vs highest and that 'column' must be numeric. The 'limit' parameter is never explained (no default or cap), so some meaning is left to the schema constraints alone.

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 operation on a specific resource: returning the highest or lowest rows of the Commercial Refinance Quotes dataset ranked by a numeric column, plus the natural-language question it answers. That is clearly distinguishable from stats/compare/search siblings in intent, though it never names those siblings or explains how it differs from them.

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 implied through the example question "which is the most/least X", which tells the agent this is the tool for superlative/ranking queries. There is no explicit when-not guidance, no mention of when to prefer dataset_search (filtering) or dataset_stats (aggregation) instead, and no stated prerequisites.

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