What this category of data looks like
Data sources are publicly available policy documents and industry regulatory guidelines in the commercial logistics sector, issued by national and local transportation authorities and state-owned asset supervision and administration institutions. Update frequency is adjusted irregularly alongside policy revisions and new standard releases. Most documents are structured clause texts, containing policy numbers, issuing entities, effective dates, applicable warehousing scenarios, core binding clauses, supporting implementation rules, and other content. Fields include policy number, issuing entity, effective time, applicable warehousing type, core clause content, implementation cycle, and more. There is no unified fixed unit format, and some clauses include quantitative implementation standards.
What constraints these characteristics impose on tool calling and plugin workflows
The structural completeness of policy documents varies by region. Policy numbers and clause formats differ across regions, requiring multiple sets of parsing rules to be adapted during tool calls. Update frequency is irregular, so plugins must support regular pulling of the latest policy data sources to maintain content timeliness. The applicable warehousing scenario field requires tool calls to filter relevant entries based on the warehousing type specified in the user's question, such as normal temperature, cold chain, or bonded warehousing. The length of individual policy documents varies widely. Overlong documents will exceed the model's context window, so pulled content must be properly chunked.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
toolChoice | auto | Adapts to multi-tool calling scenarios for warehousing policy Q&A, automatically selects matching policy query tools |
| Number of policy documents retrieved per call | Top 3-5 | Individual warehousing policy documents are relatively long; too many entries will exceed the context window |
| Timeout period | 60-120 seconds | Policy document retrieval requires cross-departmental data source queries, so sufficient response time must be reserved |
| Context chunk length | 800-1200 characters | Most individual warehousing policy clauses are under 1000 characters; chunking facilitates complete parsing |
functionCall | Triggered based on policy scenario | Only call tools when the user asks policy basis-related questions, to avoid invalid calls |
| Plugin cache maximum size | 1000 MB | Total storage volume of warehousing policy documents is relatively large, so sufficient cache space must be reserved |
Three Common Misconfigurations
- A tool call returns
SyntaxError: Your model may not support tool_call. This occurs whentoolChoiceis not configured asautoor a valid function call parameter is not specified, preventing the model from generating compliant tool call syntax. - The chat page cannot display line chart results returned by the tool. This occurs when the chart return format is not configured as a base64-encoded image string or a standard image MIME type, which does not comply with FastGPT display rules.
- The number of policy entries returned by the tool call does not match expectations. This occurs when the number of policy documents retrieved per call is outside the reasonable range, or policy data sources are not filtered based on warehousing scenarios, resulting in redundant or missing entries.
How to Confirm Proper Configuration
- Initiate a question including "supervised policies for bonded warehousing", check whether tool calling is triggered and corresponding policy entries are returned.
- View the tool call log, confirm that the
toolChoiceparameter is set to the expected value, with no syntax errors. - Verify that the policy document format returned by the tool is structured text or JSON, containing expected fields such as document number and effective date.
- Simulate a timeout scenario, confirm that valid results are returned within 120 seconds, with no timeout error.
