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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety profile is covered. The description adds that the target is a public storefront and that paging is one-based with a default of 1, which is mild context, but says nothing about pagination limits, result caps, or throttling. Adequate but not rich beyond the annotations.

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?

Two sentences, front-loaded with the core action and then the sibling routing hint. Every clause earns its place and there is no filler.

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?

An output schema exists, so return values need not be described, and both params are covered by the schema. What remains is minor: no mention of pagination limits or how many products a page returns. Complete enough for correct invocation.

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 100%, so both url and page are already documented in the schema. The description's statements ('url must be the full category-page URL', 'page is one-based and defaults to 1') essentially restate the schema rather than adding new syntax or format guidance. Baseline 3 when the schema carries the load.

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 verb (list) and resource (one product page from a public BigCommerce storefront category URL) and explicitly distinguishes itself from the sibling bigcommerce_product. The phrasing 'List one product page' is slightly awkward for what is really a paginated category listing, but an agent can tell what it does and how it differs from the product-detail tool.

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?

It names an alternative explicitly ('Use bigcommerce_product to retrieve details for a selected product URL'), giving a clear handoff condition. It stops short of covering when to prefer this over bigcommerce_search or other listing siblings, so it is clear context without full exclusions.

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