What the documents look like
Multi-store matrix management on e-commerce platforms centres on cross-store authorization and price order. The working materials named in the public brief are store authorization lists, price control tables, diversion complaint forms, and monthly sales reports. These come from platform merchant back ends, ERP channel prices, brand anti-counterfeit systems, and distributor reports. The brief gives daily and monthly update frequencies; this page does not derive any batch synchronization, full synchronization, or event-triggered mechanism from those frequencies.
The task on this page is operating reporting and exception review. In that task the tool call node reads the named materials, compares them, and produces a traceable record. Two properties of the source materials shape everything downstream. First, an authorization list entry carries a status, and a status such as pending review is not an approval. Second, a price control table entry carries a channel price with an effective period, and a value recorded there is a reference for comparison rather than an executed price decision. Retrieval of a record and collection of a form value are separate from authorization, approval, database writes, and external synchronization; those actions require their own downstream implementation.
A clearly labelled hypothetical paper exercise sample is used below. It is not a real customer, not a real company, and not a tested case.
Material text A: "Store authorization list, row 7: subject A, object platform store S1, authorization status pending review, effective scope January 2025 to December 2025."
Material text B: "Price control table, row 3: subject A, object platform store S1, field channel price, value 99 yuan, effective period January 2025 to June 2025."
Proposed handover request sentence: "Please call the price check plugin, compare store S1's channel price against the price control table, and output an exception record."
This request is in a pending state. It has not been approved and has not been executed.
Constraints at the tool calls step
A tool can be a system module such as AI dialogue, knowledge base search, or an HTTP module, or it can be a plugin. Tool calling lets the model decide the flow more dynamically instead of following a fixed flow, at the cost of more tokens. A tool has a description, which tells the model what the tool does, and tool parameters. For system modules the parameters are already fixed and need no extra configuration; for plugins the parameters are a configurable item.
Two parameter properties matter: the parameter description and whether the parameter is required. Combining the tool description, the parameter descriptions, and the required flags, the model decides whether to call the tool. A tool with no parameters is judged from its description alone. A tool with parameters and no required parameters can be called even when the context offers no suitable parameter, and the model sometimes fabricates a parameter. A tool with required parameters may not be called when no suitable parameter exists, and prompts can guide the user to supply the parameter.
In models that support function calling, multiple tools can be called in one pass. In advanced orchestration, dragging the tool call connection point makes a diamond appear on available tool headers, and that diamond connects to the diamond at the bottom of the tool call module. A connected tool automatically separates tool input from ordinary input, and its description can be edited so the call timing is more precise. Debugging tool calls remains uncertain, so the documented advice is to add tools a few at a time and tune a small set before expanding.
By default the tool call node returns the tool result to the AI, which summarizes the tool result. When that further summary is not wanted, the tool call termination node is placed at the end of the tool flow. The termination node ends the current call: no further tools are called and the AI is not called to answer about the tool call result. The custom tool variable node extends tool variable input, so nodes that are not treated as tool parameters, or that cannot be called as tools, can carry a parameter description and be called through the tool call, which then calls the workflow after them.
Configuration and implementation checks
The table lists documented settings and implementation checks for the tool call and plugin step, tied to the sample above. The values are starting points for this hypothetical exercise, chosen so they can be compared against the sample text; they are not official defaults.
| Configuration item | Hypothetical starting point for this exercise | Check method |
|---|---|---|
| Tool description | State that it reads the store authorization list and price control table, with store identifier and field name as inputs | Compare against the sample text and confirm the description states the input conditions and the situations in which the tool should not be called |
| Tool parameters | Plugin parameters set to store identifier, field name, and period | Check the parameter descriptions and the required flags; when a required parameter is missing, record that the tool was not called |
| Tool connection | Connect the price check plugin to the tool call module | Confirm that after connection the tool input is separated from ordinary input |
| Tool call termination | Attach the termination node after the comparison completes | Confirm that after termination the AI is not called to summarize the tool result |
| Custom tool variable | Fill in a parameter description for a node not treated as a tool parameter | Check that the description matches the sample fields and record which node was actually called |
| Small tool set | Add only the price check plugin first | Add other tools after tuning, and record each observation |
Three common errors
- Treating retrieval or a form as authorized execution. In the sample the authorization status is pending review, and retrieving that record does not mean the authorization has taken effect. Executable check: input the sample text and the proposed handover request, compare the authorization status field value against an effective status for the same subject, the same period, and the same field, and observe whether an authorization conclusion appears without support.
- Treating a parameter description as a guarantee of execution. In the sample the channel price is 99 yuan, and the parameter description only explains what the field means. Executable check: input the sample text and the plugin parameter configuration, compare the parameter descriptions with the required flags, and observe whether the model declines to call the tool when a required parameter is missing.
- Confusing tool call termination with AI summarization. In the sample the termination node is attached after the comparison completes. Executable check: input the termination node configuration and the tool call flow, compare whether the AI is still called to summarize the tool result after termination, and observe whether the output is only the comparison record.
How to verify the setup
- Input the two sample text sentences and the proposed handover request. Compare store S1's channel price of 99 yuan against the price control table effective period of January 2025 to June 2025, checking the same subject, the same period, and the same field. If the draft sentence outputs "exception" while the source text states no exception decision rule, the output is unsupported and the evidence gap is recorded.
- Input the sample text and the tool parameter configuration. Compare the required flag field against the parameters the sample provides. If the sample does not provide a period parameter while the configuration marks it required, observe whether the model declines to call the tool and record the actual observation.
- Input the sample text and the termination node configuration. Compare whether the output after termination contains AI summarization. If the output is only the comparison record, the condition is met; if AI summarization still appears, record it as not met. For empty-result handling, a paper input of [] can be used to check the downstream design, without claiming that a fictional rule search must return []. Cross-model retrieval association is not available; check identifiers first and exclude those that do not match.
The authorization status pending review does not by itself show that operating permission is absent. Signing, reaching cooperation, and contract effectiveness are three distinct facts. A quotation validity period does not indicate a supply period. No authorization or effectiveness clause is added to force a definite answer, and the evidence gap is kept open.
