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

With no annotations, the description carries the burden of behavioral disclosure. It correctly conveys a read-only ranking operation and the ordering direction, but it does not disclose default limit behavior, tie-breaking, or what happens with a non-numeric column. These are meaningful gaps for a tool that returns a ranked subset.

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 description is one tight sentence that front-loads the core behavior and includes a helpful natural-language query ('which is the most/least X'). It is concise with no filler, though it sacrifices some useful detail for brevity.

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?

With no annotations and no output schema, the description must carry more context, but it only covers the basic purpose. Missing details include the optional limit parameter, the ascending parameter semantics, default ordering, return format, and guidance on which sibling tools to use instead. It is under-specified for a 3-parameter tool.

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%, with only the 'ascending' parameter described in the schema. The tool description does not mention 'limit' or 'ascending' by name, adding little beyond 'highest (or lowest)' which loosely maps to the ascending flag. The required 'column' parameter is implied but not formally tied to the schema.

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 explicitly says 'Rank rows by a numeric column', and the description clarifies 'The highest (or lowest) rows of the RollCallWorks dataset by a numeric column'. This clearly distinguishes it from siblings like dataset_row (single row), dataset_search (filtering), and dataset_stats (aggregates) by focusing on row ordering.

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 descriptive phrase 'which is the most/least X' implies when the tool is useful, but there is no explicit guidance on when to prefer this over alternatives, nor any exclusions. Sibling differentiation is left to the agent to infer.

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