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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds that results come from a live Search-ShowAjax fragment and that filters derive from the response's live facets, which is useful behavioral context, but it doesn't discuss pagination, result shape, or limits.

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?

Two dense sentences that are front-loaded with the purpose, then the parameter guidance. Every clause carries information; nothing is padding.

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 needn't be described, and annotations cover the read-only/open-world profile. The description supplies the workflow dependency and parameter semantics, leaving only minor gaps around paging/limit behavior.

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%, so the description carries the burden and largely does: it explains path's source, enumerates the three sort values, and specifies filters' comma-separated field:value format from live facets. Only page and limit are left unexplained, but those are self-evident integers.

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?

States a specific verb and resource ('Browse one Balenciaga category') and clarifies it returns the site's Search-ShowAjax product-list fragment, which differentiates it from balenciaga_product (single item) and balenciaga_search (query-driven). The 'Search-ShowAjax fragment' jargon is slightly opaque but the intent is clear.

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?

Explicitly tells the agent the prerequisite workflow ('path comes from balenciaga_categories'), which is the key usage context. It also constrains the sort parameter. It does not, however, state when to prefer category browsing over balenciaga_search.

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