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

With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates a read operation (list) but does not disclose any other behaviors such as filtering behavior via the type parameter, pagination, response format, or any side effects. The description is minimally transparent beyond the basic action.

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, compact sentence that immediately conveys the core action and scope. It is front-loaded with the verb and resource, with no wasted words or redundant phrases.

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 tool with one optional parameter and no output schema, the description should clarify the parameter's effect and the structure of the returned data. It mentions pricing and purchase URLs but omits how to filter and what exact fields are returned. Given its simplicity, more context is needed to use it correctly without inspecting the schema.

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 0%, so the description must compensate for the undocumented parameter. It lists product categories (hosting, VPS, SSL, email, VPN) that loosely map to the enum values, but it never explicitly mentions the 'type' parameter or how to filter results. The link between the categories and the parameter is implicit and ambiguous, adding little semantic value.

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 states a clear verb ('List') and resource ('hosting/VPS/SSL/email/VPN products') with the added value of 'pricing and purchase URLs.' It distinctly covers the product-listing scope, clearly differentiating it from sibling tools like domain search, WHOIS, and checkout operations.

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?

No explicit guidance is given about when to use this tool versus alternatives. It does not mention any exclusions, prerequisites, or scenarios where a different sibling (e.g., recommend_server for recommendations) would be more appropriate. The context is entirely implied from the tool name and sibling set.

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