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

No annotations are provided, so the description carries the full behavioral burden. It says nothing about how many rows come back by default, the 50-row cap, tie-breaking, error behavior for non-numeric columns, or whether this is a read-only operation — all of which an agent would need.

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 tightly-packed sentence with the core action front-loaded and a helpful intent gloss. The em-dash construction and nested quotes make it slightly less scannable than it could be, but there is no wasted text.

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, no-output-schema, no-annotation tool, the description covers the essential 'what' but omits ordering defaults, result volume, and failure modes. An agent can call it, but with meaningful guesswork remaining.

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), so the description must compensate. It adds real meaning by requiring the column to be numeric and implying directionality, but it never mentions the 'limit' parameter or its bounds, leaving that semantics solely to the schema's constraints.

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 clear action (return the highest/lowest rows) on a specific resource (the Issafu dataset rows) constrained by a numeric column. It distinguishes itself from dataset_stats and dataset_search by framing the operation as a ranking/top-N query, though it never explicitly names those siblings.

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 intent phrase 'which is the most/least X' implicitly tells the agent when this tool applies, and the parenthetical '(or lowest)' hints at the ascending case. However, no alternatives are named and no conditions for choosing dataset_top over dataset_stats or dataset_search are given.

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