Get Renewal Info

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does not mention that this is a read-only operation, what happens if the domain is invalid or not found, or whether any authentication is required. This is minimal behavioral information for a tool that could have error cases.

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 that communicates the essential purpose with zero wasted words. It is concise and easy to scan, which is ideal for an agent needing to quickly understand the tool.

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 and no annotations, the description should provide more detail about what 'renewal information' includes (e.g., expiry date, price, auto-renewal status) and any edge cases. The current description is too vague to fully inform an agent about the tool's behavior, especially given the lack of sibling differentiation.

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 full coverage (100%) for the single parameter 'domain', which is described as 'Domain name'. The tool description adds no additional semantic meaning beyond what the schema already provides, so the baseline of 3 is appropriate.

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 retrieves renewal information for a domain, using a specific verb ('get') and resource ('renewal information'). However, it doesn't distinguish it from sibling tools like domains_get_details or billing_get_subscriptions which might also return renewal-related data, so it lacks explicit sibling differentiation.

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 guidance is provided on when to use this tool versus alternatives such as domains_get_details or billing_get_subscriptions. There is no mention of preferred contexts, prerequisites, or exclusions, which is a clear gap given the number of related domain and billing tools.

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