bestbuy_category

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

With no annotations, the description carries the full behavioral burden, and it does so thoroughly. It discloses the one-page limit of up to 24 items, the normalized fields returned, the default page behavior, and that requesting a page beyond the last returns an empty list rather than an error.

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 well organized and front-loaded: purpose and output shape first, then category_id, then page. Every sentence contributes actionable information without repeating schema details or adding fluff.

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?

For a two-parameter, no-output-schema tool, this description is complete. It defines the expected behavior, output fields, page size, default page, and edge-case behavior, giving an agent everything needed to confidently call and interpret the result.

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 already documents both parameters (100% coverage), so the baseline is 3. The description adds meaningful context by giving a concrete category_id example, explaining where to find that ID in the URL, and clarifying pagination behavior beyond the schema's simple name and type.

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 first sentence states a specific verb and resource: it gets a Best Buy category's product listing. It also distinguishes this from sibling tools like bestbuy_categories or bestbuy_product by focusing on a paginated, normalized product listing with specific fields.

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 description clearly conveys that this tool is for retrieving product listings for a known Best Buy category ID, and even explains how to locate the ID in a category page URL. However, it does not explicitly name sibling tools such as bestbuy_search or bestbuy_product or state when not to use this tool, so it stops short of a perfect score.

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