Quote domain register

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

With annotations present, the description adds valuable context beyond them: it discloses the return value (quoteToken), clarifies that no domain action is submitted, and states the auth requirement (domains:read plus paid domains:order scope/caps for API keys). The readOnlyHint=false annotation is consistent with creating a persistent quoteToken resource, so no contradiction.

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?

Three tight sentences with zero filler; the action, the key caveat (no submission), and the auth requirement are all front-loaded and each 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?

For a 9-parameter quote tool with no output schema, the description covers the critical call-site facts: what it returns (quoteToken), what it does not do (submit), and the required scopes. Only the explicit next-step tool name and clearer guidance on when a quote is mandated are missing.

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 the schema already documents all 9 parameters including defaults for nameservers, whois_privacy, and registrant_contact_id. The description adds no parameter-level detail, which is acceptable given the schema does the work.

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 and resource ('Create a VPSNet-priced domain registration quote') with clear pricing scope. This cleanly separates it from the sibling quote_domain_transfer, quote_domain_renew, and confirm_domain_register without needing to name them.

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?

'does not submit the domain action' implicitly defines the two-step quote-then-confirm flow and points the agent toward confirm_domain_register for actual submission. However, it does not explicitly name an alternative tool or state when a quote is required versus optional.

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