payments_create_payment

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates that a payment transaction is recorded and does not mention side effects, validation rules, defaults, idempotency, or permission requirements. This gives the agent no meaningful behavioral context beyond what the name implies.

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 very short, but the brevity is under-specification rather than effective conciseness. There is no front-loaded useful information because there is almost no information at all. For a tool with 14 parameters, this single phrase does not earn its place as a sufficient definition.

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 high complexity signaled by 14 parameters, 4 required fields, no output schema, and no annotations, the description is severely incomplete. It gives the agent no help with required fields, defaults, parameter relationships, or expected behavior. This is not enough for an agent to invoke the tool correctly with confidence.

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 only 36%, with 14 parameters and 4 required, but the description adds no parameter information whatsoever. Fields like amount, currency_id, organization_id, message, and bank_account_number remain semantically opaque in both the schema and description. The description fails to compensate for the low 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 uses a clear verb ('Record') and resource ('a payment transaction'), so an agent can discern the basic operation. It does not explicitly differentiate from payments_update_payment or payments_delete_payment, but the verb does convey creation well enough for basic purpose clarity.

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 sibling tools like payments_update_payment or payments_delete_payment. No prerequisites are mentioned, such as the need for an existing organization, currency, or payment type. The agent must infer usage entirely from the tool name and schema.

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