domainForward

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action and does not mention that this is a mutating operation, any domain ownership/prerequisite requirements, side effects on DNS, or what the response contains. This is a significant gap for a configuration-changing 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?

The description is one concise sentence that front-loads the core action, with a reference URL appended. It is appropriately short and immediately readable, though the URL could be considered boilerplate; overall it earns its place.

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 7-parameter mutation tool with no annotations and no output schema, this description is incomplete. It lacks side effects, prerequisites, response format, and any distinction from related forwarding tools. The 100% schema coverage fills parameter gaps but does not address behavior or selection context.

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 description coverage is 100%, so each of the 7 parameters is already documented in the schema. The description adds no extra parameter-level meaning, but the baseline of 3 is appropriate since the schema does the heavy lifting and the enums and examples in property descriptions are clear.

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 states a specific verb ('Forward') and a clear resource ('a domain') with a destination ('another URL'), which is unambiguous. It does not explicitly distinguish from the sibling domainForwardSubDomain, but the name and scope make the intended operation clear enough.

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 provides no guidance on when to use this tool versus alternatives like domainForwardSubDomain or dnsAddRecord. There are no prerequisites, context, or exclusions mentioned, leaving the agent to infer usage from the schema alone.

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