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

Annotations already declare readOnlyHint=true, openWorldHint=true, destructiveHint=false, so the safety profile is covered. The description contributes nothing beyond that – no pagination behavior, no result-cap semantics (the 10000 window lives only in the schema), no note that it queries live Temu GB data.

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 short sentence with no filler, so nothing is wasteful, but the brevity comes from under-specification rather than disciplined editing. There is no front-loaded statement of purpose beyond a label.

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 10-parameter search tool with no output schema and dozens of similarly named Temu/GB siblings, the definition is far too thin – it doesn't say what results look like, what defaults apply, or how to scope by region. An agent could pick the wrong Temu variant from the crowded namespace.

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 there are 10 well-documented optional parameters (page/size window rule, status codes, matchMode, hostingMode), so the schema carries parameter meaning. The description adds no parameter guidance at all, making 3 the correct baseline rather than higher.

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 is a near-verbatim restatement of the tool title ('Temu Intelligence GB: temu/goods Search API'), adding no verb-plus-resource framing beyond what the name already conveys. It doesn't distinguish this goods-search from nearby siblings such as nexscope_data_gb_temu_keyword_search, nexscope_data_gb_temu_goods_detail, or nexscope_data_gb_temu_goods_image_search.

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 indication of when to use this tool, when to prefer an alternative, or what prerequisites (regionId, catIds from category list, sites list) must be resolved first. An agent must infer everything from the schema alone.

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