Tool Calling and Plugins for Power Financing Daily Reports

What This Category’s Data Looks Like

The data for power financing daily reports comes primarily from three sources: the National Energy Administration Power Investment and Financing Monitoring Platform, public project announcements released by national power industry associations, and credit granting announcements for power projects issued by state-owned and joint-stock banks. Full daily data synchronization is completed every early morning to update the dataset. Each daily report includes 10 to 50 power project financing records. The document structure follows a standardized format. Each record contains seven core fields: project name, affiliated administrative region, financing entity type, financing amount, financing method, release date, and fund usage. Financing amount is uniformly denominated in ten thousand RMB. Release dates use the ISO 8601 format. The administrative region field is precise down to the prefecture-level city level.

Constraints Imposed on Tool Calling and Plugins

The daily updated data source requires that tool calling be configured with a daily scheduled trigger task. This avoids interface rate limiting caused by frequent data pulls. The standardized seven core fields require that the plugin’s parameter verification logic enforce two checks: first, that required fields are present, and second, that field formats match preset rules. For example, financing amount must be a positive integer, and release date must conform to ISO 8601 format. The requirement that financing amount be denominated in ten thousand RMB means that tool calling must support externally passed unit metadata and automatically complete unit conversion. The administrative region field, which is precise down to the prefecture-level city level, requires that the plugin support filtering results by region dimension and match administrative division coding rules. Additionally, the range of record counts per daily report requires that tool calling be configured with reasonable pagination parameters. This prevents timeouts caused by excessively large single return data volumes.

Configuration Settings

Configuration Item	Recommended Setting	Rationale
`toolChoice`	`auto`	Adapts to the multi-type tool calling needs of power financing daily reports, automatically selects the appropriate plugin to complete data pulling and verification
`functionCall`	`enabled`	Enables function call mode forcibly, ensuring that tool return results conform to the preset seven core field formats
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Single-batch data pulling and parsing for power financing daily reports takes a long time; 300 seconds covers the complete processing workflow
`maxContext`	`8000–12000 characters`	The concatenation of field descriptions and historical data for a single daily report must fit within the context window to avoid content truncation
`Number of Records Recalled`	`Top 20 records`	The number of valid records in a single daily report typically does not exceed 50; the top 20 records cover core financing projects
`Similarity Threshold`	`0.75`	Filters duplicate financing project announcements and retains valid data with high matching degrees

The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.

Common Misconfigurations

A 400 Bad Request error is returned when calling the FastGPT OpenAPI chat interface, with the response body containing the invalid function call format field. The cause is that the functionCall parameter is not set to enabled, causing the tool calling request to not follow the function call protocol format.
A model not supported error is returned when calling the self-built model interface via the content extraction node. The cause is that the custom_model_api parameter is not configured in config.json, and the custom model support switch is not enabled.
A connection timeout error is returned when calling the internet plugin, and external public data cannot be obtained. The cause is that domestic proxy server parameters are not configured, preventing access to overseas plugin services.

How to Verify Proper Configuration

Trigger a tool call, check that the returned result fields include the preset seven core fields and that the field formats meet requirements. Adjust the value of the Similarity Threshold based on the returned results.
Check the system logs to confirm that the tool calling duration does not exceed the preset threshold. If a timeout occurs, adjust the configuration of PARSE_FILE_TIMEOUT_SECONDS.
Test the connection of the self-built model interface, confirm that the content extraction node can call the model normally. Adjust the configuration parameters of the custom model based on the test results.
Simulate an external call to the OpenAPI interface, check that the returned response status code is 200 OK and that the response body contains compliant financing daily report data. Adjust the value of maxContext based on the test results.
