resend_confirmation

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behavioral traits: the rate limit ('Rate limited to 1 request per 5 minutes'), the precondition ('Only works for unconfirmed accounts'), and the specific use case (accounts stuck in pending_operator_confirmation). However, it doesn't mention error conditions or what happens after the email is resent.

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 perfectly concise with three sentences that each serve a distinct purpose: stating the action, providing usage context, and disclosing behavioral constraints. There is zero wasted text, and the most critical information (what the tool does) is front-loaded.

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's moderate complexity (administrative action with rate limits), no annotations, and no output schema, the description does a good job covering the essential context: purpose, usage conditions, and behavioral constraints. However, it doesn't describe what the tool returns or what happens after the email is sent, leaving some gaps in 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?

The tool has 0 parameters with 100% schema description coverage, so the baseline would be 4. The description doesn't need to explain parameters, but it does implicitly confirm there are no required inputs by describing the tool's function without mentioning any 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 clearly states the specific action ('Resend the operator anti-spam confirmation email') and the resource it operates on (confirmation emails for accounts). It distinguishes this tool from siblings by focusing on a specific administrative function rather than general email operations like sending, reading, or searching.

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 explicitly states when to use this tool ('if the account is stuck in pending_operator_confirmation status because the original confirmation email was lost or filtered') and when not to use it ('Only works for unconfirmed accounts'). This provides clear context and exclusions, though it doesn't name specific alternative tools.

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