create_payment_customization

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 merely restates the action ('Create a new payment customization') and does not mention side effects, permissions, activation requirements, or response format. This is essentially a tautology and provides no additional behavioral insight.

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 with no redundant information. It is appropriately sized for a basic create operation and front-loads the key action, making it easy to parse.

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 presence of sibling tools like set_payment_customization_activation, the description should clarify that creating a customization may not automatically activate it. It also fails to explain what a payment customization is or any operational dependencies. The schema covers parameters, but the description omits essential business context, making the description incomplete.

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 input schema already provides detailed descriptions for all four parameters (100% coverage), so the description adds no extra parameter semantics. The baseline for high schema coverage is 3, and the description does not enrich the understanding of parameters beyond what the schema offers.

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 'Create a new payment customization' clearly states a specific verb ('create') and resource ('payment customization'), distinguishing it from update/delete/get operations on the same resource. It is unambiguous and directly reflects the tool's function.

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 no guidance on when to use this tool versus alternatives like update_payment_customization or set_payment_customization_activation. It lacks any context about prerequisites, use cases, or exclusions, leaving the agent without direction on appropriate invocation scenarios.

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