What the documents look like
Platform refunds and returns occur continuously per order and do not necessarily connect to a single livestream commitment. Reports therefore accumulate order by order rather than by broadcast session. The main materials come from the platform after-sales backend, customer service chat, WMS receiving, and payment refund records. Daily documents include refund applications, return logistics waybills, quality inspection photos, and refund approvals. Operating reports and exception reviews work on the aggregation and discrepancy location of these materials. Tool calls and plugins carry the data-fetching and comparison actions here; they do not replace responsibility judgment or amount approval.
A refund application states an amount and a status. A return logistics waybill states a carrier number and movement. A quality inspection photo states observed condition. A refund approval states a pending or decided status. These are different fields on different documents. Reading them together is a retrieval and comparison task, not an authorization event.
Constraints at the tool calls step
Tool calls let the model decide from context semantics whether to execute a module or plugin. The tool introduction tells the model what the tool does. System module parameters are fixed; plugin parameters are configurable. Parameters carry two key values: parameter introduction and whether the parameter is required. With no suitable required parameter present, the model may not call the tool, and interaction can guide the user to supply the parameter. In advanced orchestration, available tools connect to the tool call module, and the documented guidance is to start with a small number of tools and tune before adding more. The tool call termination node ends the current call, calls no further tools, and does not call the AI to summarize tool results. Retrieval and recall do not constitute authorization. A report data-fetch result does not mean a refund has been approved.
Assumed drill sample: an after-sales specialist submits a paper reconciliation packet. The source text reads: "Order A-2201, return logistics waybill SF-7788, WMS receiving date 12 March 2025, quality inspection photo shows outer packaging damage, refund application amount 268 yuan, refund approval status pending review." The draft sentence to be judged is: "This order has completed the refund." This sample is used only to explain the comparison method and was not executed in a real system.
Configuration and implementation checks
| Configuration item | Value or check action on this page | Basis and boundary |
|---|---|---|
| Tool introduction | State the data-fetching purpose and the situations where the tool should not be called | The introduction affects the model's call decision |
| Plugin parameters | Check each parameter introduction and whether it is required | System module parameters are fixed; plugin parameters are configurable |
| Missing required parameter | Complete through interaction, then check the actual request | With a required parameter missing, the model may not call |
| Tool connection | Connect available tools to the tool call module, starting with a small number | Documented advanced orchestration connection method |
| Tool call termination | Attach after a tool to end the current call | After termination, no further tools and no AI summary |
| Assumed trial starting point | One order checked per pass, compared field by field against orders in the same batch | Assumed starting point for this page, not an official default |
Three common errors
- Treating a retrieval or form result as refund authorization. A successful data fetch only shows the data was read. The approval status remains pending review, and the draft sentence about a completed refund is not supported.
- Treating a parameter introduction as a guarantee of execution. A parameter description being present does not mean the model will call the tool. With a suitable required parameter missing, the call may not occur, and the actual request needs checking.
- Treating the termination node as an ordinary ending. Termination ends the current call, calls no further tools, and does not call the AI summary. A wrong attachment position changes the output path.
How to verify the setup
- Input the sample source text above and the draft sentence. Compare "refund approval status pending review" with "completed refund." These are mutually exclusive values on the same subject and the same field, so the draft sentence is not supported and the evidence gap remains.
- Input the refund application amount and the payment refund record for the same order. Compare whether the amount fields agree. When they agree, record a match. When they disagree or are missing, record as pending verification and do not infer a failure cause.
- Input the paper form [] for empty-result handling. Check whether the downstream design handles an empty result, and observe whether unsupported filling appears. Do not claim that a fictional rule search necessarily returns empty.
This page addresses only marketplace refund and return handling, operating reports and exception reviews, and tool calls and plugins. It does not treat retrieval or a form as authorized execution.
