create_payment

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

With no annotations, the description carries the full burden and does disclose two useful traits: it is a write operation and it requires the CUQU_API_KEY credential. It omits idempotency, what happens on existing/duplicate payment, and what the call returns, so mutation behavior is only partially 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?

A single dense sentence with the action, target, and credential requirement front-loaded; nothing redundant. It is efficient, though extremely terse for a mutation tool.

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 write/payment tool with no annotations and no output schema, the description should disclose what the call produces (payment params, prepay id, redirect) and side effects. It mentions only the write nature and API key, leaving the agent under-informed about the call's outcome.

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 coverage is 0%, so the schema does not document order_id at all, and the description only indirectly implies it is a registration-order identifier. The remaining semantics (format, provenance) are left to the parameter name, giving marginal added value.

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?

States a specific verb and resource (create WeChat payment) plus the target object (registration order), which clearly separates it from siblings like query_activities or register_event. It does not, however, name any sibling alternative.

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 'for registration orders' implies context but gives no explicit when-to-use trigger, prerequisite state, or exclusion relative to siblings such as generate_urllink or register_event. An agent must infer when this step belongs in the flow.

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