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

No annotations are provided, so the description carries the full disclosure burden. It conveys directionality but says nothing about the result shape, ordering ties, the 50-row cap on limit, error behavior for non-numeric columns, or that this is a read-only operation — significant gaps for a tool with zero structured behavioral 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 with the core behavior front-loaded and no wasted clauses. The trailing quoted phrase adds an intuitive gloss rather than filler, though it is slightly informal for a spec.

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 3-parameter read tool with no output schema and no annotations, the description covers the ranking intent but omits the return format (row shape/fields), how limit interacts with the cap, and behavior on non-numeric or missing values. Adequate minimum, but not complete.

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). The description partially compensates by explaining the high/low direction and that ranking is by a numeric column, but 'limit' is left entirely unspecified in both schema and description, so the gap is not fully closed.

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 outcome — returning the highest/lowest rows of the dataset ranked by a numeric column — plus an intuitive framing ('which is the most/least X'). It does not explicitly differentiate from siblings like dataset_row or dataset_stats, but the ranking/top-N purpose is unambiguous.

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 'which is the most/least X' framing implies the intended question type, but there is no explicit when-to-use/when-not guidance and no mention of alternatives (e.g. dataset_stats for aggregates vs dataset_row for a specific row). Usage is inferable but not stated.

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