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

With no annotations, the description carries the full disclosure burden, and it does state the core behavior: rows are returned ranked by a numeric column, defaulting to highest. It says nothing about read-only safety, tie-breaking, the 50-row cap on results, or how many rows come back, leaving meaningful behavioral gaps.

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 tight sentence with the resource and operation front-loaded and the em-dash clause used efficiently to illustrate intent. No filler, though the fragment structure is slightly informal for a tool definition.

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?

There is no output schema, no annotations, and only partial parameter coverage, so the description should do more. It conveys the returned-row concept and ordering but omits the result shape (which columns are returned), the limit semantics, and any note on ties or empty results.

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), so the description must compensate. It does clarify that 'column' must be a numeric column and that direction can be lowest or highest, but it never addresses the 'limit' parameter or its 1-50 range, leaving one of three parameters unexplained.

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 names a specific operation (return the highest/lowest rows) and the resource (the Taxooor dataset) with the ranking key made explicit ("by a numeric column"). It maps cleanly onto the title and is distinguishable from siblings like dataset_stats or dataset_row, though it never names an alternative tool to sharpen the contrast.

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 framing "which is the most/least X" implies the class of question the tool answers, which is real usage guidance. However, it gives no explicit conditions, prerequisites, or comparison against siblings such as dataset_search or dataset_stats, so usage is only inferred.

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