What this category of data looks like
Data related to real estate registration inquiries comes from real estate registration information systems, cadastral survey databases, housing transaction online signing systems, tax systems, and electronic certificate repositories. It updates daily. Daily business documents include registration applications, ownership certificates, surveying and mapping results, tax payment vouchers, real estate ownership certificates, and registers. Data fields cover real estate location, right type, right holder information, right restriction status, surveying and mapping area, and other relevant items. Each data entry has associated fields linked to multiple systems, with no unified fixed single document size.
What constraints these characteristics impose on tool calling and plugin workflows
Since data sources involve multiple coordinated systems, tool calling must implement linked calls across system interfaces to avoid information deviation from a single data source. Data updates daily. The cache validity period for tool calling must match the update frequency to prevent returning expired ownership status information. Business document structures are complex and linked to multiple fields. Tool calling must explicitly specify the specific fields to extract to avoid returning irrelevant content. Errors in the ownership verification link can lead to registration errors, property rights disputes, and other negative outcomes. Tool calling must add a verification step to ensure the accuracy of returned data.
How to set the configuration
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
toolChoice | auto, specify calling the "Real Estate Ownership Verification" and "Cadastral Data Comparison" tools | Adapt to scenarios requiring multi-tool linkage for real estate registration, clarify the scope of tool calling |
functionCall | Enable forced function call mode | Ensure tool calling results are returned in a structured format to facilitate subsequent ownership status verification |
| Single tool call duration | 600 seconds | Match the time requirements for cross-system queries during real estate data verification |
| Tool call retry count | 2 times | Balance system stability and query efficiency, avoid interrupting the process due to a single failed call |
| Recalled data source scope | Only enable real estate registration information systems and cadastral survey databases | Limit the data source scope to ensure data matches the business scenario |
Three common configuration errors
- Symptom: Tool calling returns empty results with no fields related to ownership verification. Cause: Required fields for registration applications and real estate ownership certificates were not specified in the tool configuration.
- Symptom: Tool calling triggers a timeout error after initiation. Cause: The single tool call duration was set too short, failing to match the time requirements for cross-system queries.
- Symptom: External search plugins fail to trigger normally and return no results. Cause: No data source adapted to the business scenario was configured, and a plugin that does not support domestic access was used by mistake.
How to verify the configuration is complete
- Initiate a test inquiry that includes an ownership verification requirement, and check whether the specified
toolChoiceconfiguration is marked as active in the FastGPT v4.17.0 tool call logs. - Review the tool call return results to confirm that required business fields such as real estate location and right holder information are included.
- Test cross-system query scenarios to confirm that the tool call duration setting meets business time requirements.
- Check the data source configuration to confirm that only real estate registration-related system interfaces are enabled, with no irrelevant data sources included.
