What the Data for This Category Looks Like
The core of the data for this category is the single vehicle identification number (VIN). Daily documents include production orders, VIN lists, assembly work instructions, tightening torque data, off-line inspection reports, repair records, and conformity release documents. Data sources cover ERP/MES systems, VIN and vehicle configuration systems, supplier batch libraries, tightening tools, EOL inspection lines, and quality traceability systems. The update rhythm is real-time data generated per vehicle, and batch data summarized per shift. Fields include VIN codes, part numbers, torque parameters, inspection results, and some parameters have clear units.
What Constraints These Characteristics Impose on Tool Calling and Plugin Workflows
The single-vehicle data feature centered on VIN requires tool calling to accurately match the full part configuration corresponding to a single VIN, to avoid misassembly risks caused by cross-vehicle mixed configuration. Real-time updated tightening data and off-line inspection results require plugin calling to have low-latency response capabilities to ensure the timeliness of bid quotations. Multi-source heterogeneous data sources require plugins to be compatible with field format differences of different systems and complete unified data verification. Bid documents need to associate hundreds of part parameters, so tool calling needs to support batch data matching to prevent subsequent production line shutdowns or recall hazards caused by configuration omissions.
How to Configure the Settings
This document is based on FastGPT v4.17.0 configuration instructions.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow/API tool selection | auto | Adapts to the dynamic configuration calling requirements corresponding to a single VIN, no need to manually specify tools |
| Workflow/API function-call configuration | enabled | Supports active calling of plugins to pull and verify cross-system data |
| Tool call timeout | 300–600 seconds | Covers the average time required to pull multi-source data across ERP and MES systems |
| Number of return entries per tool call | First 10 entries | Matches the number of core part configurations corresponding to a single VIN, avoids redundant data |
| Maximum context length | 8000–12000 token | Carries the complete content of multiple assembly work instructions and inspection reports |
| Maximum data volume per plugin call | 1000 MB | Carries the storage capacity of single-batch tightening data and inspection reports |
Three Common Misconfigurations
- Phenomenon: After enabling tool calling, the conversation return result does not include thought process content. Cause: When
toolChoiceis configured asauto, some models disable thought process output by default, and the corresponding parameter needs to be enabled additionally. - Phenomenon: Connection timeout error occurs when calling a local MCP service. Cause: The whitelist address of the local service is not added in the plugin configuration, causing access to be blocked.
- Phenomenon: The knowledge base citation identifier is not included in the conversation interface return result. Cause: The configuration item for recording citation sources is not enabled, or the corresponding knowledge base data source is not associated during tool calling.
How to Verify the Configuration Is Correct
- Initiate a test request containing a single VIN code, check whether the configuration data returned by the tool call matches the actual parameters of the corresponding vehicle.
- View the plugin running logs to confirm whether the cross-system data pulling process is executed according to the preset configuration.
- Trigger a test request containing abnormal parameters, check whether the tool call triggers the preset error handling logic.
- Check the conversation interface return content to confirm that it includes tool call related records and data source identifiers.
