Rack Warehouse fitment

Read-only

One product as its page shows it: price and sale, availability, variants, specs, summary and highlights, what a rack system includes, what it mounts to, required products, what checkout asks, rating and reviews, and its page. It does not list vehicles: use check_fit for one.

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds substantive context beyond that by disclosing the shape of the returned payload (which fields are included) and the scope boundary around vehicles — valuable given there is no output schema.

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?

Effectively two sentences, with the routing caveat placed at the end where it reads as a guardrail. The comma-delimited field inventory is dense, but since no output schema exists each item carries information rather than padding.

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?

For a one-parameter read tool with no output schema, the description supplies the missing return-content picture and the sibling boundary. What it omits — behavior on an unresolvable handle/SKU, or identifier precedence when several forms could match — is minor but non-trivial.

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

Parameters3/5

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

Schema description coverage is 100% and the single parameter already documents 'rackwarehouse.com page URL, handle or SKU'. The description adds no format, resolution or ambiguity guidance beyond the schema, so the baseline 3 applies.

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?

Names a specific resource (one product) and enumerates exactly what comes back — price/sale, availability, variants, specs, mounts, required products, rating/reviews. It also explicitly separates itself from the vehicle-lookup siblings, so an agent can route without opening the schema.

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?

Provides an explicit when-not ('It does not list vehicles: use check_fit for one') with the named alternative, which is the main routing ambiguity for this tool. It lacks positive framing of when to reach for it (e.g., when you already hold a handle/SKU/URL), so it falls short of full when/when-not coverage.

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