send_gift_card_notification_to_recipient

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

With no annotations, the description carries the full burden. It only states the action but does not disclose side effects such as whether an email is actually dispatched, any permission requirements, or whether the recipient is derived from the gift card data.

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 that immediately conveys the core action. No wasted words or fluff.

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 is minimally viable. However, it omits crucial context about the distinction between recipient and customer, and does not mention return values or side effects, leaving the agent with an incomplete understanding.

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 schema provides 100% coverage with the parameter description 'Gift Card ID', so the tool description does not need to add details. The description adds no extra meaning beyond the schema, aligning with the baseline of 3 for high schema coverage.

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 specifies the action (send email) and resource (gift card notification) to a recipient, which is clear. However, it does not differentiate from the sibling tool send_gift_card_notification_to_customer, leaving ambiguity about who the recipient is versus the customer.

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?

No guidance is provided on when to use this tool versus the sibling send_gift_card_notification_to_customer, nor any conditions or prerequisites for sending the notification.

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