What this category of data looks like
Data sources include highway maintenance management systems, bridge and tunnel monitoring systems, road administration patrol systems, and traffic flow monitoring data. The update frequency is daily. Daily documents include maintenance plans, patrol logs, defect disposal orders, road construction permits, and road property damage compensation forms. Data fields match standard identifiers and value units of corresponding business documents, and include core content such as facility location, status parameters, approval nodes, and disposal records.
What constraints do these characteristics impose on the "tool calls and plugins" workflow
Daily updated business data requires tool calls to pull the latest patrol logs and defect data in real time, to avoid using expired information. Heterogeneous data from multiple system sources requires plugins to adapt to API interface formats and permission rules of different systems. The complex structure of business documents requires tool calls to split parameters by document type, use functionCall to adapt to call formats of different systems, and ensure that transmitted fields match system requirements. Approval processes for road construction and road property damage involve multi-node statuses. Tool calls must accurately transmit corresponding status parameters, otherwise process exceptions will occur.
How to configure the settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
toolChoice | Set to auto | Allow the system to automatically match tools for maintenance business scenarios |
functionCall | Set based on actual testing | Adapt to call parameter formats for different maintenance documents |
| Tool call timeout | 600 seconds | Match the typical pull delay for road administration patrol data |
| Single tool call limit | First 8 entries | Avoid timeouts caused by pulling too many historical patrol logs at once |
| Tool call result cache | Updated daily | Match the daily update frequency of business data |
Three common mistakes
- Tool calls return
400 InternalError.Algo.InvalidParameter. The cause is failure to transmit parameters in the field format required by maintenance documents, such as omitting the kilometer stake identifier for facility location. - Tool calls return empty results. The cause is that the set single call limit is too low, so latest defect disposal orders or patrol logs are not pulled.
- Time-related tool calls throw errors. The cause is failure to adapt to the daily update time node of maintenance work orders, and the parameter format does not meet the requirements of the target system.
How to confirm correct configuration
- Initiate a simulated tool call request for maintenance plans, check if returned parameters match the field format required by the target system.
- Trigger a tool call to pull that day's patrol logs, confirm the number of returned entries matches the set single call limit.
- View tool call logs, confirm no timeout errors are triggered, and parameter transmission meets configuration requirements.
- Verify tool calls for road construction permits, confirm approval status parameters are transmitted correctly with no format errors.
