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

It adds useful context beyond annotations by stating that the tool returns a Stripe onboarding link via Stripe Connect. However, it does not explain whether setup creates an external account, how long the link lasts, or what happens on repeated calls, all relevant for an open-world, non-idempotent 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?

The description is a single, front-loaded sentence with no wasted words. It immediately states the action and the returned artifact.

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?

It covers the core action and output ('onboarding link') despite having no output schema, which is helpful. But for a two-parameter setup tool, it omits parameter meaning and key operational details such as account creation side effects or link lifecycle.

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%, and the description does not mention the 'type' or 'country' parameters at all. 'Stripe Connect' gives some domain context that could help infer that express/standard are account types, but the description does not explicitly clarify either parameter.

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 and outcome: starting card payments and returning a Stripe Connect onboarding link. It distinguishes this setup step from checkout or status siblings implicitly, but does not explicitly name alternatives.

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 phrase 'Start taking card payments' implies this is the onboarding step to use before payment operations, but it gives no explicit when-not conditions or named alternatives such as pay_checkout or pay_status.

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