gymshark_products

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

With no annotations, the description carries the full behavioral burden. It adds useful details: results are normalized, the storefront URL is fixed server-side, and valid empty result pages return 200 with an empty products array. These go beyond a bare 'list products' statement, though they don't cover rate limits, error statuses for invalid pages, or response shape.

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 concise: three sentences that front-load the purpose, then provide the source URL and an empty-page behavior note. Every sentence earns its place without filler, though it loses a point for not tackling sibling differentiation.

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 simple list endpoint, it covers the essentials: what it lists, from where, that the URL is fixed, and that empty pages are valid 200 responses. However, with no output schema and no sibling comparison, an agent is left wondering what fields 'normalized products' contain and how this tool differs from gymshark_collection_products or gymshark_sitemaps.

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?

The input schema already documents both parameters fully (page is 1-based default 1; limit default 50 max 250), so schema coverage is 100%. The description doesn't add parameter-specific meaning, but the baseline of 3 applies because the schema handles the burden.

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 opens with 'List Gymshark products', which clearly states a specific verb and resource, and then clarifies it returns normalized products from the public product catalog. It doesn't explicitly differentiate from closely named siblings like gymshark_collection_products or gymshark_product, so it misses the top tier, but the purpose is unambiguous.

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?

There is no guidance on when to use this tool versus the many Gymshark siblings. It doesn't say 'use gymshark_product for a single item' or 'use gymshark_collection_products for a collection's items', so an agent must rely on tool-name inference rather than explicit direction. The description does imply a global catalog list, but that's not enough.

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