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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and external-fetch behavior are covered. The description adds only the source domain (row.gymshark.com), which is minor scope context and discloses nothing about pagination, ordering, or what a 'static page' object contains.

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?

It is a single, front-loaded phrase with no waste, but it is under-specified rather than genuinely tight. Brevity here reflects missing content, not disciplined editing.

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 no explanation, and parameters are fully documented in the schema. However, for a paginated listing tool the description gives no indication of scope, ordering, or how it differs from closely named siblings, leaving it only minimally complete.

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% and both parameters (page, limit) are fully documented with defaults and max. The description adds no additional parameter meaning, so the baseline of 3 applies.

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 the resource (Gymshark static pages) but uses no verb and is essentially a restatement of the tool name. It does not distinguish this list tool from the sibling gymshark_page (singular) or gymshark_sitemaps, leaving the agent to infer that this one enumerates pages.

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 statement of when to use this tool versus alternatives such as gymshark_page, gymshark_sitemaps, or gymshark_collections. Usage must be inferred entirely from the name.

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