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

No annotations are supplied, so the description carries the full disclosure burden. It conveys sort direction and the numeric-column constraint, but says nothing about how many rows come back by default, what the rows contain, tie-breaking, or whether the operation is read-only — all material facts for a 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 compact sentence that front-loads the resource and operation. Nothing is wasted, though the trailing quoted example is slightly decorative rather than additive.

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 simple three-parameter read tool with no output schema, the description should at minimum state what is returned (full rows vs. ranked values) and the default result size. It establishes the ranking concept adequately but leaves those practical gaps, so it is merely sufficient to call the tool 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?

With only 33% schema description coverage, the description must compensate and largely does not. "By a numeric column" usefully constrains the `column` parameter to numeric types, but `limit` is documented nowhere — neither the schema nor the description states its purpose, default, or 1–50 range.

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?

States a specific operation (returning the highest/lowest rows) on a named resource (the Background Check Quotes dataset) qualified by a numeric column. This is clearly distinguishable from dataset_stats or dataset_search in intent, though the description never names a sibling to sharpen the boundary.

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 quoted phrasing "which is the most/least X" gives an implicit trigger for when to reach for this tool, which is helpful. However, it offers no exclusions or alternatives, so an agent must infer on its own whether dataset_stats or dataset_search would be a better fit for ranking-style questions.

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