batch_create_payments

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

With no annotations, the description carries the full burden of revealing behavior. It only says 'create multiple payments', which is a write operation, but it omits critical batch characteristics such as atomicity, partial failure handling, error reporting, idempotency, or response shape. This is insufficient for a batch tool.

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 redundancy. It is front-loaded and economical, though it could use the available space to add valuable batch context without harming conciseness.

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?

The tool has no annotations and no output schema, so the description must explain return values, error behavior, and batch semantics. It only states the basic action, leaving out essential context like whether the batch is atomic, what happens if one payment fails, and what is returned. This is incomplete for a batch operation.

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% for the top-level 'payments' parameter (described simply as 'Array of payments to create'), and the description adds no extra meaning about the array elements or required fields. Baseline 3 applies due to 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 clearly states the verb ('create') and resource ('payments'), and the modifier 'batch' distinguishes it from the singular sibling tool create_payment. However, it does not explicitly differentiate from alternatives beyond the name, so it stops short of a 5.

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?

There is no guidance on when to use this tool versus create_payment, no mention of batch size limits, or any exclusions. The 'batch' wording implies multiple payments, but that is already evident from the name and does not constitute practical usage guidance.

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