Disable domain lock

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

Annotations already mark the call as destructive, non-read-only, and idempotent. The description supplies the strategic effect of unlocking the domain to prepare for transfer but does not add further behavioral detail such as irreversibility or authorization requirements; that is acceptable given the annotations, so a mid score is appropriate.

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 short and front-loaded with the action. The third sentence ('Use this endpoint...') restates the second sentence's purpose, creating slight redundancy, so it is not perfect.

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 single-parameter, annotation-rich tool, the description covers what the call does and when to use it. No output schema exists, and a return-value explanation is not essential here; the only minor gap is not describing result or error conditions, but this does not hinder correct invocation.

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?

There is one required parameter, domain, and the schema already documents it as 'Domain name' with 100% coverage. The description does not need to add semantics because the parameter is self-explanatory.

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 first sentence states the exact action and object: disable the domain lock for the domain. The added context that this is for preparing domains for registrar transfer makes the purpose concrete and differentiates it from the sibling enableDomainLockV1.

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 explicitly says domain lock must be disabled before transferring the domain to another registrar, giving a clear condition for use. It does not explicitly list when not to use it or mention alternatives, but for a direct inverse operation this is clear enough.

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