Tool Calling and Plugins for Water Utility Financing Daily

What the Data for This Category Looks Like

Data sources for water utility financing daily reports include public resource trading platforms, local water utility authority submitted ledgers, and internal financing project systems of water utility groups. Updates occur daily for new financing projects from the previous day. Each record corresponds to a single independent financing project. The document structure is project-centric, and includes fields such as project code, project type (water supply, sewage treatment, pipeline network renovation, etc.), financing amount (unit: ten thousand RMB), financing channel, signing date, amount already disbursed, administrative district the project belongs to, and approval status. There is no multi-level nested structure.

What Constraints These Characteristics Impose on Tool Calling and Plugins

The daily update schedule requires tool calling to set a fixed synchronization cycle. This avoids frequent pulling that exceeds data source interface rate limits. The multi-field structured data requires tool calling input parameters to strictly match the preset field format. Specifically, amount fields must use numeric types, not string types. Otherwise, data aggregation exceptions will occur. The detailed project type classifications require tool calling to add category-specific filter conditions. This filters out non-water utility financing projects. The need to pull data from multiple sources requires plugins to support connecting to multiple data source interfaces. Plugins must also handle differences in return formats across interfaces to avoid data parsing failures.

Configuration Settings

Configuration Item	Recommended Setting	Rationale
`max_tool_calls_per_round`	3–5 times	Water utility financing daily reports require pulling multi-source data, performing amount aggregation and regional grouping per round. 3-5 times covers conventional needs and avoids timeout interruptions
`data_source_sync_interval`	1 time per day	Matches the daily update schedule of the daily report, avoids frequent pulling that exceeds data source interface rate limits
`tool_prompt_template`	Filter by "project type + region + financing status", only return new projects from the last 24 hours	Aligns with the properties of the daily report, avoids returning redundant historical data, focuses on new water utility financing projects from the current day
`plugin_auto_retry`	Retry 2 times, interval 10 seconds	Addresses occasional timeouts on public resource trading platform interfaces, reduces the probability of data pulling failures
`result_cache_ttl`	23 hours	Matches the daily report update schedule, ensures the cache expiration time is earlier than the next synchronization, avoids returning old data
`filter_condition`	Only include water supply, sewage treatment, and pipeline network renovation projects	Matches the exclusive project types of the water utility category, filters out non-water utility financing projects

The parameter values provided on this page are all common recommendations used as starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to conduct testing on relevant samples before finalizing the configuration.

Three Common Misconfigurations

Phenomenon: When calling the water utility financing daily report plugin, a 400 Bad Request is returned, with the prompt "invalid parameter type". Cause: The plugin input parameter mapping was not configured according to the field format of the water utility financing daily report. The "financing amount" field was incorrectly mapped to a string type instead of a numeric type, resulting in data aggregation failure.
Phenomenon: No intermediate reasoning steps are output during the tool calling process. Only the final aggregated result is returned. Cause: The enable_chain_thought configuration item was not enabled, and the tool prompt template did not include intermediate step guidance content. This causes the model to skip the thinking process and directly output the result.
Phenomenon: When calling the conversation interface, the returned result does not include the associated knowledge base ID field. Cause: The return_source_info configuration item was not enabled, or the water utility financing daily report knowledge base was not bound to the currently used tool calling chain. This results in the inability to return associated source information.

How to Confirm the Configuration Is Complete

Manually trigger the water utility financing daily report tool call. Verify that the returned results only include water utility financing projects from the last 24 hours, and that the fields include preset items such as project code and financing amount.
View the FastGPT tool calling logs. Confirm that the plugin retry times and timeout settings match the configured items, with no continuous timeout error records.
Enable the return_source_info configuration item, then call the conversation interface. Verify that the returned result includes the associated knowledge base ID field.
Adjust the max_tool_calls_per_round parameter. Test that a single round of calls can complete all preset data source pulling and data organization tasks, with no mid-run interruptions.
