platform_create_order

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

With no annotations, the description carries the full burden, and it does disclose key behavior: no merchant credentials needed, required environment variables, and return values. It does not mention side effects, error conditions, or idempotency, but the core behavioral profile is reasonably transparent for an order-creation 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 compact sentence that front-loads the platform name and key advantage, then states prerequisites and return values. Every piece of information earns its place with no fluff.

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?

The description covers the essential purpose, prerequisites, and return values, which is enough for a basic call. However, with no annotations, no output schema, and weak parameter documentation, it leaves scene/channel/mchNo semantics under-specified, so an agent may still be uncertain when constructing a full request.

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 20% (only 'channel' has a description), and the tool description does not explain any parameters. The phrase '免商户凭证' weakly implies mchNo is not needed, but subject, amountYuan, scene, and channel semantics are left entirely to the schema, which mostly lacks descriptions.

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 order on the 夏天pay hosting platform and returns an order number and cashier link. It distinguishes itself from the direct WeChat/Alipay sibling tools by emphasizing '免商户凭证' (no merchant credentials), though it never names an alternative explicitly.

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?

It gives clear context for when this tool is appropriate: when using the hosted platform without merchant credentials. It also states the required environment variables as prerequisites. However, it does not explicitly say when not to use it or name alternative sibling tools.

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