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 genuinely non-obvious behavior: page=N accumulates upstream pages 1..N rather than returning a single page, the default yields 36 products, and the response carries its own pages_count. That pagination disclosure is valuable context beyond the annotations.

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?

Front-loads the return contents, then moves to parameter behavior. Dense and mostly waste-free, though the pagination explanation is somewhat repetitive ('Gucci's own category pages page this way...not a single page's worth') and could be tightened.

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 re-explained, and the description instead fills the more important gap: pagination semantics and the category parameter's origin. For a two-parameter browse tool this is essentially complete, with only the sibling-routing detail left implicit.

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 must carry parameter meaning, and it does: category is sourced from gucci_categories' category field, and page is explained with its accumulation semantics, default value, per-page product count, and the recommended value (pages_count) for a complete listing.

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+resource ('One Gucci category/browse listing') and enumerates what it returns (normalized products with name/price/colors/images/stock plus counts and sort options). It references gucci_categories as the source of the category field, which implicitly distinguishes it from the category-index sibling, but it does not explicitly contrast itself with gucci_search or gucci_product.

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?

Provides clear operational context: the category value comes from gucci_categories' own category field, and it explains the accumulation semantics and how to request the full listing via pages_count. It gives no explicit when-not or named alternative (e.g. gucci_search), so it stops short of full routing guidance.

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