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

Annotations declare readOnlyHint=false and destructiveHint=true, but the description adds no additional behavioral context. It does not elaborate on consequences, required ownership, or the transfer process, so the description fails to provide value beyond the annotations.

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 extremely short but under-specified, repeating the title without adding information. This is not effective conciseness; it's a placeholder.

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 a nested object schema with required properties, yet the description provides no context about domain creation vs. transfer, auth code requirements, or what the response contains. It is completely inadequate for an agent to invoke this tool correctly.

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 description does not mention any parameters. With schema description coverage reported at 0%, the description offers no compensation, leaving agents to infer parameter meaning solely from the schema (which does have some descriptions, but the tool description itself is mute).

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 is a verbatim repetition of the title ('Create or transfer a domain'), making it a tautology. It states the action but provides no differentiation from related tools like updateDomain or confirmDomainTransferOut.

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 usage guidance is provided. The description does not specify when to use this tool versus createInstance, transfer alternatives, or any prerequisites such as handles or auth codes.

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