List premium subscription products

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

With no annotations present, the description carries the burden of behavioral context. It usefully discloses that the same API key opens both catalogs, that pricing depends on reseller tier, and that the premium catalog uses a separate USD wallet. It does not mention rate limits or response shape, but for a read-only list operation this is adequate.

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 two compact, information-dense sentences. The first sentence defines the contents, and the second adds the key operational distinction between premium and store, with no filler or redundancy.

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 parameterless list operation, the description covers scope, pricing, authentication, and catalog/wallet separation. It does not describe the return envelope or possible pagination, and there is no output schema to offload that, leaving a minor gap.

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 zero parameters and schema coverage is 100%, so the baseline is 4. The description adds relevant context about what premium products are, but no parameter-specific documentation is required.

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 tool name and title already supply a specific verb and resource, and the description enriches this by defining premium products as reseller-tier subscription seats and explicitly marking them as a separate catalog from the store. This clearly distinguishes it from store catalog siblings such as search_catalog and get_product.

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 gives clear context for when to use the tool by stating that premium products are a separate catalog and separate USD wallet from the store, while sharing the same API key. It does not explicitly name alternative tools such as get_premium_product or list_smm_services, so it stops short of full exclusion guidance.

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