combell_domains_transfer

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

The description goes well beyond the annotations by disclosing that the operation incurs costs, runs asynchronously, returns a 202 Accepted, and requires checking the returned provisioning job. This is exactly the kind of behavioral context an agent needs before invoking the tool.

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?

Two sentences, front-loaded with the primary action and the critical side effect. No filler, and the asynchronous behavior is stated clearly and compactly.

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 complex transfer operation with no output schema, the description covers the essential contextual points: cost, asynchronous execution, and where to check the result. It does not explain failure modes or prerequisites beyond the EPP code, but the core invocation context is sufficiently covered.

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 adds the 'EPP' framing for the auth_code, but the input schema already documents the parameters thoroughly, including registrant object details and name server meaning. The description does not add significant parameter-level meaning beyond the schema.

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 names an exact operation (transfer), the resource (a domain name), and the required credential (EPP/auth code), making the tool's intent unambiguous. It is clearly distinct from sibling tools like register, set_nameservers, or list because 'transfer' is a specific lifecycle action.

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 clearly implies when to use the tool: when transferring an existing domain into Combell using an EPP code. However, it does not explicitly state when not to use it or point to alternatives such as combell_domains_register for new registrations.

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