get_cart_payment_options

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

No annotations provided. Description only adds 'including campus-card availability' beyond the name. Does not disclose whether it requires authentication, modifies state, or any other behavioral traits. With no annotations, the burden is on the description, which is minimal.

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?

Single sentence is concise, but it under-specifies the tool. It is not verbose, yet fails to provide enough detail. Earns a neutral score.

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 an output schema, return values are covered. However, the tool has one parameter with no description, no usage guidelines, and minimal behavioral info. Incomplete for an agent to use correctly.

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 description coverage is 0%. The only parameter, cart_id, is not explained in the description. No hint about format or how to obtain it. The description adds no value beyond the schema.

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?

Description clearly states it retrieves cart-scoped payment options and specifically mentions campus-card availability. The verb 'get' and resource 'cart-scoped payment options' are specific. However, it does not explicitly differentiate from siblings like get_payment_methods, which might be user-level.

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 on when to use this tool versus alternatives such as add_payment_to_cart or get_payment_methods. No context about prerequisites or typical use case.

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