mail_resendForwarderConfirmationV1

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

No annotations provided, so description carries burden. Mentions forwarder must be unconfirmed, but lacks details on side effects, authorization needs, error states, or behavior if 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?

Single sentence, no wasted words. Action verb is front-loaded: 'Resend the confirmation email...'

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 simple tool with one required parameter and no output schema, description is largely sufficient. Could mention error conditions (e.g., if forwarder already confirmed) for completeness.

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%, so baseline is 3. Description does not add meaning beyond schema's 'Forwarder resource ID' for the forwarderId parameter.

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?

Description clearly states the action (resend confirmation email) and target (unconfirmed forwarder). Differentiates from sibling tools like mail_createForwarderV1 (creation) and mail_resendCatchAllConfirmationV1 (different entity).

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?

Implies usage when a forwarder is unconfirmed and needs a confirmation email resent, but no explicit guidance on when not to use or contrast with similar tools like mail_resendCatchAllConfirmationV1.

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