tiendanube_create_coupon

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 the tool's functionality (creates coupons with various features) but omits details about side effects, error handling, or authorization requirements. Adequate but not comprehensive.

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 four sentences long and front-loaded with an emoji and imperative 'CREATE'. It is mostly concise, though the use of emoji and capitalization may be extraneous. Every sentence adds value, but minor redundancy exists.

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?

With 10 parameters and no output schema, the description covers use cases and supported features well. However, it lacks information about expected return value (e.g., created coupon object) and error scenarios. Adequate for a creation tool but could be more 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 coverage is 100%, so each parameter has a description in the schema. The tool description adds context about overall capabilities but does not enhance understanding of individual parameters beyond what the schema provides. Baseline score 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 'CREATE' and the resource 'NEW COUPON', explicitly listing use cases like launching sales and customer retention. It distinguishes itself from sibling tools by focusing solely on coupon creation.

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 provides clear guidance on when to use the tool ('launching sales, customer retention, first-time buyer discounts, and seasonal promotions'), but does not explicitly mention when not to use it or alternatives. The context is sufficient for selecting this tool over non-related siblings.

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