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

No annotations are provided, so the description carries the full burden. It does not state that the operation is read-only, does not mention the 50-row cap on results, does not explain tie-breaking or default ordering beyond what the schema says, and gives no sense of 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 tight sentence with the core operation front-loaded and no filler. The em-dash clause is slightly informal but earns its place by capturing the user intent.

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 three parameters, no output schema, and no annotations, the description should do more work. It omits the result-size cap, the default sort direction, and any indication of what a returned row looks like, leaving meaningful gaps for an agent to guess at.

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' is documented), so the description must compensate. It implies column ranking and direction via 'highest (or lowest)', but never mentions the 'limit' parameter or its 1-50 bounds, leaving a third of the parameters undocumented in both places.

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 (returning the highest/lowest rows) on a specific resource (the Medicare Plan Comparison dataset) and frames the intent with 'which is the most/least X'. It is clearly distinguishable from dataset_row or dataset_search, though it doesn't explicitly name a sibling to contrast with.

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 'which is the most/least X' framing implies the question shape this tool answers, giving implied usage context. However, there is no explicit guidance on when to prefer this over dataset_stats, dataset_search, or dataset_row, and no exclusions stated.

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