Realtime Bestsellers V2

Get the current Best Sellers (BSR-ranked) products for an Amazon category.

Data is collected on demand (typically 2-5s latency). Provide either categoryId (Amazon category node id, e.g. 172282) or categoryPath (e.g. ["Electronics"]); page 1 = ranks 1-50, page 2 = 51-100. Discover category ids via /categories. Related: /products/search for daily catalog data.

TDQS

A3.9/5.0
Behavior3/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It usefully notes 'Data is collected on demand (typically 2-5s latency)' and explains pagination, but it does not mention authentication, rate limits, or the behavior when both categoryId and categoryPath are provided.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The opening summary is concise, but the description is bloated with large response schemas, including irrelevant ADR-0003 credit-field TODOs and a tokensUsage note about video polls that has no bearing on this endpoint. This extra boilerplate undermines the otherwise tight structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple parameter set and absence of a dedicated output schema, the description covers the essential invocation details: parameter alternatives, pagination, latency, and related endpoints. The response schema is included but does not describe the 'data' payload structure, so an agent can call the endpoint correctly but not fully predict the returned product fields.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds value by explaining the either/or relationship between categoryId and categoryPath, giving a concrete example, and referencing /categories for discovery, which is beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action and resource: 'Get the current Best Sellers (BSR-ranked) products for an Amazon category.' It also introduces the key differentiator of real-time/on-demand data and points to /products/search for daily catalog data, helping distinguish it from sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly instructs to provide either categoryId or categoryPath, tells users how to discover category IDs via /categories, and contrasts this endpoint with /products/search for daily catalog data. It lacks an explicit 'when not to use' statement but gives sufficient routing context.

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