kyliecosmetics_product_recommendations

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

With no annotations, the description carries the behavioral disclosure burden. It adds meaningful traits: the handle is resolved to a Shopify product ID before fetching, and the storefront URL is fixed server-side. It stops short of describing response details, error behavior, or rate limits, but for a list operation the provided detail is solid.

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 compact and front-loaded, but the first two sentences are redundant ('List...' and 'Returns...' restate the same action). The embedded URL adds minor noise, and the message could be tightened into two sentences without losing information.

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?

For a 3-parameter recommendation tool with 100% schema coverage and no output schema, the description covers the key call requirements: one handle, optional limit and intent, handle resolution, and a fixed storefront URL. It could specify the fields returned by 'normalized recommended products', but the operation is simple and the description is adequate for an agent to invoke 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 100%, so baseline is 3. The description adds value by clarifying that 'handle' is a route handle resolved to a Shopify product ID and that the storefront URL is server-side fixed, which tells the agent what not to pass. It does not expand on limit or intent, but the handle clarification is useful.

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?

Description states a specific verb ('List'), resource ('Kylie Cosmetics product recommendations'), and scope ('for one product handle'), making the tool's function clear. It implicitly distinguishes itself from product detail or collection tools by focusing on recommendations for a single handle, though it does not name sibling alternatives.

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 usage: provide a product handle to receive recommendations. It does not explicitly state when to use this tool versus kyliecosmetics_product, kyliecosmetics_products, or other recommendation tools, nor does it mention any exclusions or prerequisites beyond having a handle.

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