wayfair_product

Retrieve full details of a Wayfair product by its W-prefixed ID, including name, brand, price, stock, ratings, images, and variant options.

Instructions

Get a Wayfair product's full detail. Returns one Wayfair product's full detail: name, brand, price, stock status, aggregate rating with a 1-5 star breakdown, images, every selectable variant option (e.g. color, finish), and site-selected feature highlights. id is the product's own "W"-prefixed id (e.g. W100794312), taken from a category result's product_id field or a product page's URL. An unrecognized id returns 404.

Tool call template

A3.9/5.0
Behavior3/5

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

No annotations are provided, so the description carries the transparency burden. It discloses that an unrecognized id returns 404 and meaningfully lists the product details returned. It does not, however, mention auth requirements, rate limits, or whether this is a read-only operation, leaving some useful behavior undisclosed.

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

Conciseness4/5

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

The description is well-formed and informative, with the key purpose and output fields front-loaded. It repeats that phrase 'full detail' twice, which is slightly redundant, but overall every sentence contributes useful information and the length is appropriate.

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 there is no output schema, the description compensates well by enumerating the key returned fields, describing how to obtain the input id, and stating the 404 error condition. A complete, concise definition for a single-parameter retrieval tool, though it could mention whether the price includes currency or special cases.

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?

The input schema already gives 100% coverage for the 'id' parameter, but the description adds explanatory value: it specifies that the id is Wayfair's own 'W'-prefixed identifier, gives an example, and explains where the id originates. This is more than the schema alone provides and reduces operation errors.

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 clear verb and resource: get a single Wayfair product's full detail. It enumerates the returned fields (name, brand, price, stock status, ratings, images, variants, highlights), distinguishing it from more generic or composite endpoints. Although it is one of many product-detail tools, the domain and mapping are unambiguous.

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

Usage Guidelines3/5

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

It explains that the id should come from a category result's product_id or a product page URL, implicitly signaling that this tool follows id discovery via category or page. However, it does not explicitly state when to use this tool versus alternatives, nor does it mention exclusions such as needing to call a search endpoint first.

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