mail_resendCatchAllConfirmationV1

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

No annotations are provided, so the description carries full burden. It discloses that the tool targets unconfirmed catch-alls, which is a behavioral constraint. However, it does not mention side effects, idempotency, permissions, or what happens if the catch-all is already confirmed, limiting transparency.

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, concise sentence of 14 words with no redundant information. Every word contributes to clarity.

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 parameter and no output schema, the description sufficiently covers the main action and target state (unconfirmed). It could mention prerequisites or error conditions, but the core information is present. Given the low complexity, this is nearly complete.

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 has 100% description coverage for the single parameter 'catchallId'. The tool description adds no additional meaning beyond the schema's 'Catch-all resource ID', so the baseline of 3 is appropriate.

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 the verb 'Resend' and the resource 'confirmation email to the mailbox address of an unconfirmed catch-all'. It distinguishes from sibling tools like mail_resendForwarderConfirmationV1 by specifying the resource type (catch-all vs forwarder).

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 when to use the tool: when there is an unconfirmed catch-all needing a resend of the confirmation email. It does not explicitly mention when not to use it, but the condition 'unconfirmed' provides a clear scope. Lack of explicit alternatives or exclusions prevents a higher score.

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