What the data for this category looks like
Urban water services business data primarily comes from official business handling systems and offline service guide archives. Data update rhythm is adjusted according to business rules, such as synchronizing updates when new water supply connection processes are revised or water price adjustment notices are released. Individual business documents are split by handling scenarios, including handling conditions, application material lists, process nodes, handling time limits, offline handling addresses and contact numbers. Fields include business number, water meter account number, and payment account number. Units mostly use working days, square meters, and yuan per cubic meter.
What Constraints These Data Characteristics Impose on Tool Calling and Plugins
Urban water services business data is split by scenario and includes exclusive identifiers. When calling tools, first verify the legality of fields such as the water meter account number and business number provided by the user to avoid processing invalid requests. Data updates follow no fixed cycle, so the tool calling link must support dynamic retrieval of the latest business rules, and must not rely on static caching. Handling processes and charging standards vary across different administrative divisions, so tool calling must bind the corresponding dataset for the user's region to ensure returned content matches local rules. In addition, process nodes in individual documents are mostly linear steps, and tool calling must guide users to complete material submission and information confirmation for each link in sequence.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
toolChoice | auto | Adapt to tool calling requirements across multiple business scenarios such as water supply installation and payment inquiry |
| Single tool call timeout | 20–30 seconds | Water service business data mostly consists of structured queries, so no long waiting time is needed |
| Tool call result cache duration | 12–24 hours | Water service business rules change at low frequency, this range balances real-time performance and system efficiency |
| User input validation fields | Water meter account number, business number | Water service business handling requires binding exclusive identifiers to avoid invalid calling requests |
functionCall | Trigger according to preset business functions | Preconfigure calling functions for corresponding business scenarios to simplify calling logic |
Three Common Misconfigurations
- Only enabling knowledge base retrieval without configuring tool calling plugins results in inability to call external business system data. Phenomena include only returning knowledge base content during calls, being unable to provide the latest handling processes or charging standards, and no relevant trigger records in tool calling logs. Causes include not binding tool plugins for water service business handling, or not enabling tool calling permissions.
- Not configuring user input field validation leads to empty results from tool calls. Phenomena include returning "No corresponding business information found", and no water meter account number or business number entered by the user carried in tool calling logs. Causes include not adding exclusive field validation logic in the tool calling link.
- Not setting a reasonable tool call timeout duration causes call failure. Phenomena include returning status code 408 or a "Request timed out" prompt. Causes include an overly short timeout setting that cannot complete structured data queries from water service business systems.
How to Verify Correct Configuration
- Use the tool calling log panel in FastGPT v4.17.0 to initiate a simulated water service business handling request, input a valid water meter account number, and check whether tool calling logs are triggered.
- Review the tool calling return results to confirm that the returned handling processes, offline addresses and other information match the public guidelines from local water service departments.
- Simulate a request that exceeds the set timeout duration, and check whether the corresponding timeout prompt is returned.
- Test streaming response scenarios to confirm whether tool calling results are displayed in segments on the interface.
