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

With no annotations, the description carries the safety and behavior burden. It does disclose that the result is the highest or lowest rows by a numeric column, but it omits how limit defaults behave, how ties or non-numeric values are handled, and what the return payload looks like. The core ordered-retrieval behavior is clear, but the behavioral context is not rich.

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?

The one-sentence description is compact, puts the operation first, and adds a short illustrative use-case without redundancy. It is slightly informal and the em-dash phrasing could be cleaner, 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 simple 3-parameter tool with no output schema and no annotations, the description covers the core invocation but leaves gaps: limit's default value, invalid column behavior, and the result row shape are not addressed. Sibling dataset_columns could supply valid column names, but the description doesn't point to it.

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 has a description), so the description should compensate for column and limit. It adds that column must be numeric, but limit has no meaning or default discussed anywhere, and ascending is only indirectly reflected by 'highest (or lowest)'. Thus parameter semantics are under-specified.

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 title and description both anchor on a specific operation: ranking rows of the Card Machine Pricing dataset by a numeric column, with the 'most/least X' phrasing making the ordering intent explicit. This clearly distinguishes it from sibling tools like dataset_row (single row retrieval) and dataset_stats (aggregations).

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 description implies a use case ('which is the most/least X') but never states when to prefer dataset_top over siblings such as dataset_search or dataset_stats, nor gives exclusions. An agent must infer usage from the name/title rather than from explicit routing guidance.

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