What this category of data looks like
This category of data is mainly sourced from the road transport administration system, the national public service platform for dynamic information of road transport vehicles, and the vehicle and practitioner database. The update frequency is daily. Associated daily documents include business license application materials, vehicle technical files, driver qualification materials, work safety management systems, and official road transport business licenses. Data fields cover business entity qualifications, vehicle technical parameters, practitioner qualifications, site and safety configurations, and other items. All fields follow official system standard formats, with no custom units.
Constraints on Tool Calling and Plugin Workflows
Daily updated data requires tool calling to adapt to high-frequency synchronization logic, to avoid calling expired data. Multiple official data sources must be connected via separate plugins. Differences in field formats across different data sources require plugins to perform unified mapping processing. Associated daily documents include multiple types of structured and unstructured materials, so tool calling must support parsing license application and file documents in different formats. Data related to business licensing is directly linked to approval results. The accuracy requirements for tool calling are higher than general scenarios, so it is necessary to strictly verify the official source identifier of returned data. In addition, tool calling must comply with security specifications for government data calls, to avoid unauthorized access to restricted data.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
toolChoice | auto | Adapt to the dynamic tool calling needs of policy basis Q&A, no need to manually specify a single tool function |
functionCall | enabled | Support active triggering of tool calls to obtain real-time updated policies and data related to road transport business licensing |
| Number of items returned per single tool call | Top 3–5 items | Policy basis content requires precise matching; too many entries will increase the burden of context processing |
| Tool call timeout period | 600 seconds | Government data source interfaces usually take a certain amount of time to respond, avoid prematurely terminating the query due to timeout |
| Plugin data source verification | Enable official source verification | Road transport data has strict authority requirements; it is necessary to confirm that returned data comes from designated government platforms |
| Context window size | 8000–12000 token | Must accommodate the complete content of multiple policy documents and business application materials, to avoid truncation of critical information |
Three Common Misconfigurations
- Symptom: The interface returns the
The tool call is not supportederror. Cause: ThefunctionCallconfiguration item is not enabled, ortoolChoiceis set tonone, causing the system to fail to trigger the tool calling logic. - Symptom: Tool calling fails after deploying the plugin, and configuration matches historical versions but does not take effect. Cause: Plugin authentication parameters do not adapt to the interface verification rules of FastGPT v4.17.0, or the local data connection link is not properly configured.
- Symptom: Policy data returned by tool calling does not match official content. Cause: Plugin data source verification is not enabled, or field formats of different government data sources are not properly mapped.
How to Verify Successful Configuration
- Enter the FastGPT tool configuration page, confirm that the
toolChoiceandfunctionCallconfiguration items match the preset values. - Initiate a test query to verify whether tool calling can be triggered normally and return policy content from the corresponding data source.
- Check whether the plugin's data source verification switch is enabled, to ensure that returned data carries official source identifiers.
- In FastGPT v4.17.0, view the tool calling log module to confirm that the number of returned items matches the preset range, and there are no abnormal timeout situations.
