What this category of data looks like
Data for declaration materials and case review for advanced chemical materials comes primarily from provincial advanced chemical materials industry filing systems, internal enterprise R&D filing ledgers, and previously approved declaration archives. Filing system data is synchronized monthly, while internal enterprise ledgers are updated quarterly. Each individual declaration material includes structured fields and unstructured attachments. Structured fields include product name, synthesis process route, designed production capacity, safety compliance certificate number, and more. Units include tons/year, kg/m³, MPa, and others. Unstructured attachments are mostly test reports and process flow PDFs, with each attachment up to several megabytes in size. Document lengths vary widely, with core text ranging from hundreds to tens of thousands of characters.
What constraints do these characteristics impose on the tool calling and plugins workflow
Mixed structured and unstructured data characteristics require tool calling to support both structured field validation and unstructured text parsing, to avoid single tools failing to cover all review requirements. Differences in update rhythms across data sources require plugins to be configured with scheduled pull mechanisms, ensuring that the latest versions of filing standards and review rules are used for calls. Special field and unit requirements require tools to automatically match corresponding formats during calls, preventing review failures caused by inconsistent units or missing fields. The presence of long documents and large attachments requires tool calling to support chunked processing and attachment parsing, avoiding context overflow or information loss.
How to Configure the Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
toolChoice | auto | Adapts to the mixed scenario of advanced chemical materials declaration materials, which require both structured validation and unstructured parsing, to automatically select the appropriate tools |
| Single tool call limit | Top 3 | Matches the number of core review fields per declaration material, avoiding excessive calls that cause timeouts |
| Context window | 8000–12000 token | Covers the average length of a single declaration material, preventing information loss from long document truncation |
| Error retry count | 2 times | Balances call success rate and resource consumption, adapting to tool requests during network fluctuations |
| Attachment parsing trigger threshold | 5000 characters | Automatically calls the attachment parsing tool when the declaration material text exceeds this threshold, to process long attachments such as test reports |
Three Common Misconfigurations
- Phenomenon: Significant differences between online chat and API call results. Core fields remain missing even when
stream: falseanddetail: trueare set in API requests. Cause: The dedicated advanced chemical materials review tool plugin was not bound in the API request, so the corresponding data validation rules were not loaded during API calls. - Phenomenon: Calling the MCP tool with the xinference large language model returns a 400 error, but runs normally when no tool is called. Cause: The MCP tool's data source does not adapt to the output format of the xinference model. Structured field validation for advanced chemical materials requires a specific JSON structure, and the mismatch causes format parsing failure.
- Phenomenon: Using the Claude4 model to call tools returns a Bedrock-related error. Cause: The request timeout setting for tool calls does not match the response duration of the Claude4 model. Long document parsing for advanced chemical materials requires a longer timeout window, and the default setting is insufficient, causing request interruption.
How to Verify Proper Configuration
- Submit a standard advanced chemical materials declaration material, check if the tool call return's validation results cover dedicated fields such as product production capacity and process route.
- View the API call log, confirm that the
toolChoiceparameter is set toautoand the corresponding tool call action is triggered. - Simulate a single network fluctuation scenario, check if the tool call automatically retries according to the set number of retries.
- Upload declaration material text exceeding 5000 characters, confirm that the attachment parsing tool is automatically triggered and loaded.
