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

No annotations are supplied, so the description carries the full burden. It does disclose the meaningful behavioral detail that a full status timeline is returned and enumerates the possible states (paid, merchant_accepted, shipped with waybill, delivered, refunded), which is genuinely useful. It says nothing about read-only safety, auth requirements, or the size/shape of the timeline for long-lived orders.

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 line with no filler and the core purpose front-loaded. It is a fragment rather than a sentence, which costs a little readability but wastes nothing.

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 one-parameter read tool with no output schema, the description adequately conveys what comes back. It is incomplete on the parameter's semantics and on routing relative to similar siblings, but nothing catastrophic is missing.

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 0% and the single required parameter order_no is undocumented in both schema and description. The description does not clarify the expected order-number format, whose order namespace it belongs to, or what happens if the order is unknown.

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 (get) and resource (order status) and adds scope by naming the event timeline it returns. It does not, however, differentiate itself from the sibling get_logistics or the various cps_*_orders tools, so the agent must infer the boundary.

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 when-to-use statement, no prerequisites, and no mention of an alternative tool. The description only characterizes the payload, leaving the agent to guess how this differs from get_logistics or cps_jd_orders.

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