Create a payment provider connect link

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

The description adds useful output context by stating the tool returns an onboarding URL and a deep-link, which is beyond the annotation information. However, it does not disclose potential side effects, whether a connection record is persisted, or whether the link expires, leaving some behavioral ambiguity for a non-read-only 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 two sentences with no redundant wording. It front-loads the primary purpose and then immediately states the output, making it efficient and easy to parse.

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 tool with only two simple parameters and no output schema, the description covers the core purpose and return values well. It could mention link expiration or whether the operation only generates a link versus creating a persistent provider connection, but the current level is sufficient for basic invocation.

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 100%, so the schema already documents both store_id and provider_id adequately. The description does not add parameter-specific details beyond what the schema provides, so it does not elevate the semantics further.

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 creates an onboarding link for connecting a payment gateway, with a specific verb and resource. It also distinguishes itself from sibling tools like ecommerce_listStorePaymentProvidersV1 by describing the returned artifacts: a gateway onboarding URL and a store admin deep-link.

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 tool is used when a merchant needs to connect a payment gateway, but it does not explicitly mention when to prefer this over related tools or when not to use it. There is no exclusion or alternative routing guidance, leaving the context implicit rather than fully explicit.

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