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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds only the vague 'one department' scoping and says nothing about pagination, result size, or whether the designer list is complete or curated.

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?

A single short sentence with no filler and the scope qualifier placed up front. Its brevity is appropriate in form, even if the content is thin.

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 shape need not be described. However, for a one-param discovery tool the definition omits what the parameter means and what the response enumerates, leaving the agent under-informed about both input and intent.

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 coverage is 0% and 'gender' has no description or enum in the schema. The phrase 'for one department' weakly implies the parameter partitions results, but the description never states that gender is the required parameter, nor which values (e.g. women/men) are accepted. It does not compensate for the coverage gap.

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 (designers) and the site (Moda Operandi) but the verb 'discovery' is soft and the qualifier 'for one department' is ambiguous — it reads as a scope statement yet the only input is 'gender', so the agent must guess whether department == gender division. It distinguishes itself from modaoperandi_product/search only by resource noun, not by stating what the call returns.

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?

No when-to-use guidance, no prerequisites, and no mention of sibling routes such as modaoperandi_search or modaoperandi_categories that also surface merchandise. The agent is left to infer that this is the browse-by-designer entry point.

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