create_payment

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

No annotations, so the description carries the full behavioral burden. It says 'Create' (a mutation) and mentions optional allocation, but omits auth/permission needs, whether the payment is created as draft or posted, how AutoPost or allocations behave, and whether it can be reversed/voided. Significant gaps for a financial write operation.

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?

Two tight sentences with the required-input contract front-loaded ahead of the optional allocation detail. No filler, though it is quite terse for a multi-field object payload.

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?

For a nested, annotation-free mutation tool with no output schema, the description covers the core intent and required fields but leaves behavioral questions open (posting state, allocation rules, error/reversal behavior). Adequate but with clear gaps.

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 description restates the schema's own required fields (customer ID, date, method, amount) and the allocation option, adding little beyond the structured schema. The nested properties in the schema are individually documented, so the baseline of 3 applies; the description does not explain constraints like whether allocations must sum to the amount.

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?

Clear specific verb+resource: 'Create a customer payment (AR)' in a named system. The '(AR)' qualifier plus 'customer payment' implicitly distinguishes it from siblings like create_bill_payment (AP) and create_deposit, though no sibling is named explicitly.

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?

States the required inputs and the optional allocation use case, which implies when to use it, but gives no explicit when-not or alternative routing (e.g., vs create_deposit, create_sales_receipt, or create_bill_payment). Usage context is inferable but not spelled out.

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