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. 'Create a payment record' implies a write operation but does not specify permissions, side effects (e.g., updating invoice status), error conditions, or response format. This is inadequate for a mutation tool with zero annotation coverage.

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, efficient sentence with no wasted words, making it appropriately concise and front-loaded. However, this conciseness comes at the cost of under-specification, but the structure itself is optimal.

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 tool's complexity (a write operation with 4 parameters), lack of annotations, 0% schema coverage, and no output schema, the description is severely incomplete. It does not explain what the tool does beyond the name, how to use parameters, or what to expect in return, making it inadequate for effective agent use.

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%, meaning none of the 4 parameters (amount, invoice_id, method, payment_date) are documented in the schema. The description adds no information about these parameters, such as their purposes, formats (e.g., date format for payment_date), or constraints, failing to compensate for the coverage gap.

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 payment record' restates the tool name 'create_payment' with minimal elaboration, making it tautological. It specifies the verb 'create' and resource 'payment record', but lacks detail on what a payment record entails or how it differs from other create operations like create_invoice or create_cost, failing to distinguish from siblings.

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, such as create_invoice for billing or get_payments for retrieval. There is no mention of prerequisites, context, or exclusions, leaving the agent without usage direction.

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