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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds real behavioral context beyond that: the 60-item page cap, the /plp/ path convention, the default site value, and that result_count reflects the upstream total regardless of page size.

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?

Purpose is front-loaded in the first sentence, followed by per-parameter detail; every sentence carries information. It is dense but not padded, with only mild jargon (SFCC-native page) that could be clearer.

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?

With readOnly/openWorld annotations and an output schema present, the description need not explain return values, and it still notes result_count semantics. All three params, the page cap, and the sibling discovery path are covered, leaving nothing an agent needs to call it correctly.

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 0%, so the description must carry the load and does: it defines category as the slash-separated path segment after /plp/ with a concrete example and a discovery pointer, states site selects the storefront with a default of jcrew, and explains page as the SFCC-native page index.

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+scope: one page (up to 60 products) of a J.Crew or J.Crew Factory category/browse listing. It also names the sibling jcrew_categories, so an agent can distinguish it from the category-discovery tool without opening a schema.

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?

Gives clear context: use it for category/browse listings and route to jcrew_categories to discover valid category values. It does not, however, contrast this against jcrew_search or state when a browse listing is preferable to a search, so the alternative-selection guidance is incomplete.

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