search_all_product_skus

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

The description discloses that the tool fetches all pages in parallel, indicating potentially heavy network activity. However, without annotations, it does not mention safety (e.g., read-only), rate limits, or data volume warnings. The description adds some behavioral context but lacks completeness.

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 a single, front-loaded sentence with no redundant information. It effectively communicates the core action and scope without wasted words.

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?

The description covers the parallel fetching mechanism but omits details about the output format, error handling, or how it differs from sibling tools like search_all_products. Given the existence of an output schema, this gap is partially mitigated, but the description could be more informative about usage context.

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?

The input schema has a single optional parameter 'q' (anyOf string or null, default null) with 0% schema description coverage. The tool description does not explain the parameter's meaning or usage. Since the tool name implies search, 'q' is likely a search query, but the description fails to clarify this.

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 clearly states the tool's action: 'Fetch ALL product SKU variants across all pages in parallel.' It specifies the resource (product SKU variants) and the scope (all pages, parallel), distinguishing it from paginated listing tools like list_product_skus.

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?

The description implies this tool is for retrieving the full set of SKU variants without manual pagination, but it does not explicitly state when to use this over alternatives like list_product_skus or search_all_products. No exclusions or when-not-to-use guidance is provided.

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