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

The annotations declare readOnlyHint=true, yet the description describes 'writes' and instructs not to cache or automatically retry them, and 'Confirm Receive' is inherently a state-changing order action. This is a direct conflict with the structured safety signal, so the description contradicts rather than supplements the annotations.

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?

Three short sentences, front-loaded with the operation and followed by auth and retry constraints; little waste. 'Use your Nexscope API key' is somewhat boilerplate and consumes a sentence without adding decision-relevant information.

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, no-output-schema mutation it covers auth prerequisites and the no-retry rule, which is useful. It omits the effect on order state, idempotency behavior, and error cases when the authorization is expired or the order is not in a receivable state, leaving gaps for a write operation.

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 both parameters are already well documented in the schema, including the string-encoded positive integer and the requirement that confirmReceive be JSON true only after explicit user confirmation. The description adds no further meaning about aliOrderId format or confirmReceive semantics beyond what the schema states.

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 action (Confirm Receive) bound to the current Nexscope user, and the parameter aliOrderId makes it clear this targets a 1688 order, distinguishing it from siblings like nexscope_data_alibaba1688_order_status, cancel_order, and create_order. It stops short of stating explicitly that the order's state transitions to 'received', but an agent can identify the operation.

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 a real precondition — an ACTIVE, unexpired 1688 authorization owned by the current user — plus an operational rule not to cache or auto-retry writes. However, it never says when this action should be taken relative to alternatives (e.g., only after goods arrive, versus using logistics_trace or order_status to verify delivery first), which is the guidance an agent most needs.

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