domains_createWHOISProfileV1

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

No annotations are provided, so the description must cover behavioral traits. It only states 'Create' and 'add', but fails to mention idempotency, return values, permissions, or side effects like overwriting existing profiles. This is a significant gap for a write operation.

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 concise with two sentences, front-loading the purpose. However, the second sentence is somewhat redundant, and the brevity might sacrifice necessary detail for a complex create 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?

The tool has 5 parameters with nested objects (tld_details and whois_details have empty property schemas) and no output schema. The description does not explain how to structure these nested objects, what the endpoint returns, or any prerequisites, leaving significant gaps for correct usage.

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 defines each parameter. The tool description adds no extra meaning beyond what the schema provides, meeting the baseline of 3.

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 creates a WHOIS contact profile for domain registration, using specific verbs 'Create' and 'add'. It distinguishes itself from sibling tools like domains_getWHOISProfileListV1 and domains_deleteWHOISProfileV1.

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 provides a clear usage context ('Use this endpoint to add new contact information for domain registration'), but lacks explicit when-not-to-use guidance or direct comparison to alternatives. However, the sibling tools are distinct enough that the purpose is well-understood.

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