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

The description adds real context beyond the annotations (authorization ownership requirement, no caching, no auto-retry, no automatic payment), but its phrase 'do not automatically retry writes' implies this call mutates state, while the annotations declare readOnlyHint=true. Combined with the required post-confirmation flag, the tool clearly has side-effect weight, so the read-only framing is at odds with the stated behavior.

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?

Front-loaded with the resource and scope, followed by prerequisites, safety warnings, and return behavior, in five compact sentences. The 'Use your Nexscope API key' sentence is generic boilerplate but harmless.

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 two-parameter tool with no output schema, the description covers the key agent unknowns: auth prerequisite, confirmation requirement, live/non-cacheable responses, and that only a link is returned so no payment happens automatically. The remaining gap is how it fits among the other 1688 order tools.

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 50%, with both properties carrying inline descriptions (order ID format, confirmation semantics), so the schema does substantial work. The description adds only indirect meaning ('returns a payment link only'), and says nothing about the fact that orderIdList accepts multiple orders or about the confirm-flag gating beyond the schema text.

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 names a specific resource (a 1688 payment URL) and ties it to the authenticated Nexscope user, so the agent knows this retrieves a pay link rather than creating or cancelling an order. It does not explicitly contrast itself with siblings in the 1688 procurement family (create_order, order_preview, order_status), so the differentiation is inferred from the name and order flow rather than stated.

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?

Clear preconditions are given: a valid Nexscope API key plus an ACTIVE, unexpired 1688 authorization owned by the current user, and the confirmGetPaymentUrl flag requires prior explicit user confirmation. It also warns not to cache or auto-retry. It stops short of naming which sibling tool to call before or after this one in the procurement flow.

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