create_automatic_discount_basic

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

No annotations are provided, so the description must disclose all behavioral traits. It only states it's an automatic amount-off discount. It does not mention side effects, prerequisites (e.g., requiring a cart), or that it creates a new resource. The description is too brief to adequately inform an agent about behavior beyond the obvious creation.

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 sentence, which is concise but lacks necessary detail. It could be considered under-specified rather than effectively concise. It earns its place but does not add value beyond the tool's name.

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 complexity (13 parameters, nested objects, no output schema), the description is severely lacking. It does not explain return values, confirmation of creation, or any criteria details. The agent would need additional context to use this tool effectively.

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 has 13 parameters with 54% description coverage, but the description adds no parameter information. It does not explain any parameters or their roles. The agent must rely solely on the schema, which is incomplete. The description fails to compensate for the low 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 clearly states the tool creates an automatic amount-off discount (percentage or fixed). It explicitly says it's applied without a code, distinguishing it from code-based discounts. The term 'amount-off' and mentioning both percentage and fixed amount differentiates it from sibling tools like BXGY or free shipping.

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 this tool is for automatic discounts (no code required) and mentions 'when cart meets criteria,' indicating it's for condition-based discounts. However, it does not explicitly state when not to use it or contrast it with other automatic discount types (e.g., BXGY, free shipping). The context is clear but lacks exclusions.

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