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, and it delivers little beyond the ranking idea. It does not disclose the default number of rows returned (limit has no schema default), tie-breaking, pagination, or what the returned rows look like.

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 core operation front-loaded, plus a short example phrase that earns its place. No redundancy or filler.

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 tool with no annotations, no output schema, and only 33% parameter coverage, the description is too thin. An agent still cannot tell how many rows come back by default, how ties or nulls are handled, or how the output is shaped.

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%, so the description must compensate. It usefully implies 'numeric column' (a constraint not stated in the schema, which allows any string) and clarifies the high/low meaning that maps to 'ascending'. The 'limit' parameter is left undocumented in both the schema and the description.

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 (return highest/lowest rows ranked by a numeric column) on a named resource (Bags That Pay dataset). An agent can infer the core behavior, but the description never distinguishes itself from nearby siblings like dataset_row, dataset_stats, or dataset_compare, so the boundary is ambiguous.

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 question shape this answers, which is useful implied guidance. However, there is no explicit statement of when to use this versus dataset_stats or dataset_search, and no prerequisites are given.

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