domains_createWHOISProfileV1

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

Without annotations, the description carries the full burden. It does not disclose any behavioral traits such as idempotency, side effects, auth requirements, or what happens on duplicate attempts. Mutation is implied but not detailed.

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 main action. However, it could be slightly more structured (e.g., specifying required parameters or output).

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?

Given the complexity (nested objects, no output schema), the description is incomplete. It doesn't specify what the response contains (e.g., profile ID) or how to structure the nested objects. Siblings dealing with WHOIS profiles imply a flow, but not explicit.

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 coverage is 100%, so the schema already documents all parameters. The description adds no additional parameter meaning, especially for nested objects (tld_details, whois_details) whose structure is left unspecified. Baseline 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 it creates a WHOIS contact profile for domain registration. While it doesn't explicitly differentiate from sibling create tools, the resource (WHOIS profile) is distinct from others like domain forwarding.

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?

Only a general directive to 'use this endpoint to add new contact information' is given. No guidance on when to prefer this over other methods, no prerequisites, and no mention of alternatives like update or delete.

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