Update Domain Forwarding

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. However, it merely restates the tool name ('Update domain forwarding/redirect') without adding any information about side effects, irreversibility, required state, or what happens upon execution. This is essentially a tautology.

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 that directly states the action. It is concise and avoids unnecessary verbosity, although it sacrifices informational richness for brevity.

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?

Despite being a simple tool with only 3 parameters and no output schema, the description is too minimal to be contextually complete. It does not explain what 'update' entails, whether the operation replaces existing forwarding, or any expected behavior, leaving the agent without sufficient context for 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?

Schema description coverage is 100%, with each parameter (domain, redirect_to, type) already described in its own schema field. The description adds no extra parameter semantics, but the baseline of 3 is appropriate because the schema fully documents parameters.

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 uses a specific verb ('Update') and resource ('domain forwarding/redirect'), which clearly conveys the tool's function. It does not explicitly differentiate from sibling tools like create or delete forwarding, but the verb itself implies modification of an existing rule.

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 such as domains_create_forwarding or domains_delete_forwarding. It does not mention any prerequisites, context, or conditions that would help an agent decide to invoke it.

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