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

The description notes that the category_id is a closed set from upstream and references a shared filter param, which adds context beyond the readOnly/openWorld annotations. It does not, however, disclose pagination or rate-limit behavior that the annotations leave unstated.

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?

Three sentences that get to the point quickly with no wasted filler. The closed-set note and the comparison to moncler_search are front-loaded and useful, though the phrase "the same normalized result and facet shape" is somewhat redundant.

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?

Given that an output schema exists, the description need not explain return values, and it correctly focuses on the category_id constraint and result structure. It omits when to prefer this tool over moncler_search, which would complete the guidance.

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%, so every parameter already has documentation. The description adds emphasis on the closed-set nature of category_id and the repeatable filter, but this largely restates information already present in the schema.

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 states a specific verb ("browse") and resource ("one Moncler category") and distinguishes itself from moncler_search by explaining it returns the same normalized result shape. This is clear but relies on the reader inferring the exact output duplication, which is slightly less direct than naming the distinction outright.

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?

It implies usage by tying category_id to moncler_categories' closed set, but offers no explicit when-to-use versus moncler_search, which handles the same normalized results with a free-text query. An agent could reasonably use either.

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