Create payment link

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

With no annotations provided, the description bears the full burden of behavioral disclosure. It explicitly states that card data is never handled by the API and that the token is saved on success, offering valuable security context. It does not cover failure modes or response specifics, but the essential process is transparent.

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 concise, two sentences, with the purpose front-loaded and no wasted words. It effectively conveys the core function and a key security trait without verbosity.

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 11 parameters, no output schema, and no annotations, the description is insufficiently complete. It explains the high-level flow but does not clarify parameter usage, prerequisites, or the response shape, leaving an agent to guess on most inputs.

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 9% (only paymentCycle has a description). The description does not compensate by explaining any parameters. With 11 parameters, the agent has no guidance on required vs. optional fields or their semantics beyond raw names, leaving significant ambiguity.

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 tool builds a secure hosted payment link (Tranzila) for adding a card to an organization. It names the specific resource ('hosted payment link') and the purpose, distinguishing it from sibling tools like add_payment_method or create_paid_account, which operate differently.

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 implies the use case: when you need a customer to submit card details via a hosted link. It mentions sharing the URL with the customer, which is part of the usage flow. However, it does not explicitly state when not to use it or contrast it with alternatives such as add_payment_method, leaving some ambiguity.

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