Resend forwarder confirmation

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

Annotations indicate readOnlyHint=false and destructiveHint=false, so the description's statement that an email is resent adds some behavioral context beyond the annotations. However, it does not disclose potential side effects such as duplicate sends, expiration, or behavior when the forwarder is already confirmed.

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, clear, front-loaded sentence with no wasted words. It efficiently conveys the action, target, and condition.

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 tool with one parameter and no output schema, the description adequately covers the action and target. It lacks some detail about edge cases or response behavior, but the simplicity of the tool means this is not a major gap.

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 coverage is 100%, and the single parameter forwarderId is described as 'Forwarder resource ID'. The description adds little beyond the schema, mentioning the destination address but not providing additional guidance on obtaining or formatting the ID.

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 and resource: 'Resend the confirmation email' to an 'unconfirmed forwarder'. It also specifies the destination as the forwarder's destination address, which clearly distinguishes it from sibling tools like mail_resendCatchAllConfirmationV1.

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 implies the tool is for unconfirmed forwarders where the confirmation email needs to be resent, but it does not explicitly state when to prefer this over alternatives or add exclusions. Usage context is inferred from 'unconfirmed forwarder' rather than directly guided.

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