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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered; the description adds genuinely new context about authorization scope and that procurement responses are live and must not be cached. The trailing clause "do not automatically retry writes" is confusingly misapplied to a read-only status lookup and slightly muddies the behavioral picture, keeping it from a 5.

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?

Four short sentences with the purpose and auth scope front-loaded; nothing is padded. The final sentence about writes and caching is the one piece that does not clearly earn its place in a read-only status 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?

With no output schema, the agent gets no indication of what status fields come back (fulfillment state, timestamps, payment state), which is important for a status-query tool. Auth requirements and data freshness are covered, so it is adequate but incomplete for the tool's core job.

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 100% and the single parameter aliOrderId already documents its pattern and JSON-string encoding requirement. The description adds nothing about the identifier or what an invalid ID yields, so it neither compensates nor detracts — baseline 3 applies.

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 opens with "Order Status for the currently authenticated Nexscope user," which is essentially a restatement of the title and tool name rather than a verb-plus-resource statement. It never says it retrieves the current status of a specific 1688 order given an order ID, and it does not distinguish this read from nearby siblings such as nexscope_data_alibaba1688_order_preview, _logistics, or _cancel_order.

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 states real prerequisites — a Nexscope API key and an ACTIVE, unexpired 1688 authorization owned by the current user — which tells the agent when the call is even possible. However, it gives no guidance on when to choose this tool over order_preview, logistics, or logistics_trace, and no when-not-to-use conditions.

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