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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action ('resends') and outcome ('allows them to confirm their email address'), but does not disclose critical behavioral traits such as required permissions, rate limits, whether it triggers notifications, or error conditions. The description is insufficient for a mutation tool with zero annotation coverage.

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 well-structured with a title, action explanation, parameter details, and return value—all in four concise sentences. Each sentence adds value without redundancy, and key information is front-loaded. It efficiently communicates the tool's purpose and usage.

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?

Given the tool has an output schema (implied by 'Returns: Confirmation that the email was sent'), the description does not need to detail return values. It covers the purpose, parameters, and basic outcome adequately. However, as a mutation tool with no annotations, it could benefit from more behavioral context (e.g., side effects, error handling) to be fully 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?

Schema description coverage is 0%, so the schema provides no parameter descriptions. The description compensates by explaining the semantics of both parameters: 'user_id: User ID to resend confirmation for' and 'email: Email address that should receive the confirmation email'. It adds clear meaning beyond the bare schema, though it could include format examples (e.g., email format requirements).

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 specific action ('resends an email confirmation message') and the target resource ('to the user's email'), with a distinct purpose from sibling tools like 'send_password_reset_email' or 'send_new_email'. It explicitly differentiates by focusing on email confirmation rather than password reset or general email sending.

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 usage context (when a user needs to confirm their email address) but does not explicitly state when to use this tool versus alternatives like 'send_password_reset_email' or 'register_new_user'. It provides basic context but lacks explicit guidance on prerequisites or exclusions.

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