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

Annotations already establish that this is a read-only, non-destructive, non-open-world operation. The description adds useful behavior beyond annotations: pagination is 20 per page, and the first page also returns available filters and the total. It does not describe authentication or rate limits, but for a read-only browse tool that is a minor gap.

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 compact and front-loaded: it starts with the core scope, then enumerates supported browsing dimensions, then notes pagination and first-page metadata. Despite listing many capabilities, it does so efficiently without redundant explanation.

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 12-parameter browsing tool with no output schema, the description provides important context: page size, first-page filter/total metadata, and supported filtering and sorting dimensions. It still does not describe the shape of returned product objects, but the schema and annotations cover most other needs.

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 every parameter is already documented in the input schema. The description restates the main filter and sort capabilities in prose, including BRL price range and the available sort dimensions, but adds little semantic detail beyond what the schema already provides.

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 clearly states the resource and scope: products from one store, browsable by category, tag, brand, filters, price, stock, sale/featured status, and sort order. It distinguishes itself implicitly from broader search by requiring a single store, but it does not explicitly contrast with sibling tools such as search_products or list_categories.

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 implies usage by framing the tool as browsing products of one store like the store website, but it gives no explicit when-to-use guidance, prerequisites, or alternatives. An agent can infer that this is for store catalog browsing rather than product lookup or search, but the routing guidance is not spelled out.

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