Create Domain Forwarding

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

With no annotations provided, the description carries full responsibility for disclosing behavioral traits. It merely states the action without mentioning prerequisites (e.g., domain ownership verification), side effects (e.g., immediate activation), or failure modes (e.g., behavior if a forwarding already exists). This is sparse for a mutation 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 a single, front-loaded sentence with no filler. It efficiently conveys the core purpose without redundancy. For a simple tool, this is appropriately concise.

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 description covers the basic purpose but omits useful context such as whether the 'type' parameter defaults to 301, whether an existing forwarding is overwritten or causes an error, and what the response format will be (given no output schema). While not terrible for a simple tool, it leaves several practical questions unanswered.

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 input schema already provides 100% coverage with descriptions for all three parameters (domain, redirect_to, type), so the description adds no extra parameter-level meaning. The baseline of 3 is appropriate; the schema handles the heavy lifting.

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 a specific action ('Create') and resource ('domain forwarding/redirect'), which unambiguously distinguishes this tool from sibling tools like domains_update_forwarding, domains_delete_forwarding, and mail_forwarders_create. The term 'domain' clarifies that this is for web domain redirects, not email forwarders.

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 guidance is provided on when to use this tool versus alternatives such as domains_update_forwarding or mail_forwarders_create. The only signal is the verb 'Create,' which implies a new forwarding, but the description does not explicitly explain the separation of concerns or any conditions that would make this tool inappropriate.

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