run_amazon_seller_products

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

No annotations are provided, so the description carries the full burden. It does disclose the returned fields and the cost model ('1 point per returned record'), which is genuinely useful behavioral context, but says nothing about pagination behavior, rate limits, permissions, or failure modes.

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?

Two short sentences with zero filler: the scope/return fields come first and the billing note last. Every clause earns its place.

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 no output schema, the description usefully enumerates the returned fields, and the cost signal covers an otherwise invisible constraint. The only gap is behavioral detail around pagination and result limits, which matters for a 250-item-capped listing tool.

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% (seller, domain enum, max_items, start_page all documented), so the baseline is 3. The description adds no parameter-level meaning (e.g. how seller IDs are obtained, or pagination interaction between max_items and start_page) beyond what the schema already states.

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 (List) plus the resource (products sold by an Amazon seller's storefront) and enumerates the returned fields. This distinguishes it in scope from run_amazon_seller (seller profile) and run_amazon_product_search (keyword search), though it never names those siblings explicitly.

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 scope in the description implies the usage condition (you have a seller ID and want their catalog), but there is no explicit when-to-use, when-not, or pointer to alternatives such as run_amazon_seller or run_amazon_product_search.

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