acedatacloud_pay_order

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 disclosing side effects. It mentions that confirm=true is required, which hints that the action may not take effect otherwise, but it does not state whether this creates a charge, mutates the order, requires authentication, or what happens when confirm=false. This is too thin for a payment-related tool.

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 filler or redundant phrasing. It communicates the primary action and the critical confirm requirement immediately. This is appropriately sized for the core semantic content, even though other dimensions suffer from missing detail.

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 payment tool with four parameters, two enums, no annotations, and a large sibling set, the description is incomplete. It lacks context about the payment flow, how it relates to acedatacloud_create_order or invoice tools, and what the output session represents. The existence of an output schema helps with return values but not with workflow selection.

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?

The input schema already describes all four parameters, including enums for pay_way and surface, so baseline is 3. The description's 'Requires confirm=true' is useful emphasis but duplicates the schema field description 'Must be true to create payment state.' No additional parameter meaning is added beyond the schema.

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 core action: 'Create a payment session.' This is a specific verb-plus-resource statement that distinguishes the tool from order-level tools like acedatacloud_create_order or invoice tools. It does not deeply explain how this relates to those siblings, so it is not a 5.

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 alternatives such as acedatacloud_create_order, acedatacloud_apply_invoice, or acedatacloud_get_order. The only instruction is 'Requires confirm=true,' which is a parameter requirement, not a usage guideline. The agent gets no workflow context.

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