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

No annotations are provided, so the description carries the full burden, and it discloses little beyond the ranking direction. It does not say how many rows are returned by default, how ties are broken, that the result set is capped, or anything about the return shape.

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 operation front-loaded and no filler. It is efficient, though the trailing quoted example is only marginally informative.

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 tool with no annotations, no output schema, and low schema description coverage, the definition should explain the default result size, the limit cap, and ordering behavior. None of that is present, so an agent cannot predict the response.

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 usefully establishes that the column must be numeric and that the tool can return highest or lowest, but it says nothing about 'limit' or its maximum of 50, leaving a real gap.

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 (rank/return top or bottom rows) on a specific resource (the Injection Molding Cost Checker dataset) constrained by a numeric column, and gives a plain-language framing ('which is the most/least X'). It is distinct from siblings like dataset_stats or dataset_row, though it never names them explicitly.

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 'which is the most/least X' phrasing implies the intended question shape, so usage is inferable, but there is no explicit when-to-use statement and no routing to alternatives such as dataset_stats or dataset_search for different query types.

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