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

The annotations already establish that this is a read-only, open-world tool, and the description adds useful behavior: results are paginated, amazon.se may return /dp/ASIN buy links, and other marketplaces use search-ideas catalogMode. It does not contradict the annotations and gives regional behavior that an agent would not otherwise know.

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?

The description is short and front-loads the core resource before regional and parameter notes. The final OpenAPI reference is somewhat internal, but overall there is little wasted text.

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 eight parameters, no output schema, and low schema description coverage, the description is too sparse to fully equip an agent. It does not explain the catalog filters, pagination mechanics beyond the word 'paginated,' or what the curated results contain.

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 only 25%, so the description must compensate for undocumented parameters. It reinforces the required marketplace and locale fields, but gives no meaning for q, limit, offset, moveType, roomFocus, or budgetBand, leaving most filtering and pagination semantics unexplained.

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 identifies a specific resource: a paginated curated housewarming starter catalog. It hints at differentiation from search with 'Search remains primary,' but it does not explicitly name or contrast with the sibling search_kits tool.

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 that search is the primary path and this catalog is secondary, but it never states exactly when to use this tool versus search_kits or other siblings. The requirement to always pass marketplace and locale is usage-adjacent but does not define invocation scenarios.

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