Declaration Materials and File Review for Shipbuilding: Tool Calling and Plugins

Declaration Materials and File Review for Shipbuilding: Tool Calling and Plugins

What the data for this category looks like

The data for declaration materials and file review in shipbuilding mainly comes from classification society inspection documents, ship construction process ledgers, design drawing approval records, and material incoming inspection submission forms. Data updates follow the single-ship construction cycle, with new content added in stages from launch filing to delivery acceptance. The document structure includes structured parameter sections and long-text record sections. Structured fields include hull steel number (unit: millimeter), main engine power (unit: kilowatt), and total tonnage (unit: ton). Long-text sections include process inspection reports, rectification notices, and similar content. Each file is bound to a unique ship inspection number as its identifier.

The single-ship exclusive nature of ship files requires tool calling to be bound to a unique ship inspection number to avoid cross-ship data confusion. The mixed document structure of structured fields and long text requires tool calling to support both structured field extraction and unstructured text parsing modes. General logic alone cannot handle all content. Fixed unit rules require tool calling plugins to include built-in unit verification logic to prevent parameter format errors. The staged update feature requires tool calling to dynamically match the file content of the current construction stage without loading full historical data.

How to set the configurations

In FastGPT v4.17.0, tool calling and plugin configurations must match the characteristics of the shipbuilding scenario, as detailed below:

Configuration ItemRecommended SettingRationale
functionCallEnable structured field extraction modeMatches the characteristic that ship files contain structured parameters such as hull steel number and main engine power
Maximum context per single tool call8000–12000 tokenAdapts to the text length range of core declaration materials for a single ship, calibrated based on actual testing
Tool call timeout600 secondsMeets the processing cycle requirements for complex inspection record parsing
Knowledge base association ruleBind exclusive knowledge base by ship inspection numberEnsure only declaration and file data for the corresponding single ship is called
toolChoiceFixed call of specified toolsAvoid repeated tool calls, matches the fixed verification process of ship file review
Result format verificationEnable unit consistency verificationAdapts to the fixed unit requirements for ship parameters, such as millimeter, kilowatt, ton

Three common errors

  • Phenomenon: Tool call nodes execute repeatedly, with logs showing repeated triggering of the same verification logic. Cause: toolChoice is not set to fixed call mode, causing the workflow to repeatedly trigger tool calls.
  • Phenomenon: Structured field extraction results are empty, with extraction failure displayed on the interface. Cause: The structured mode of functionCall is not enabled, and only general text parsing logic is used, which cannot match the fixed field rules of ship parameters.
  • Phenomenon: Tool call times out, returning status code 504. Cause: The single call context is set too small and does not cover the text length of the complete single-ship declaration materials, resulting in unfinished parsing.

How to confirm the configuration is correct

  • Submit the single-ship inspection number as a variable to trigger the workflow, check that the tool call is executed only once.
  • After extracting structured fields, verify that the units of parameters such as hull steel number and main engine power match the preset rules.
  • Check the workflow logs to confirm that no timeout error is triggered for the configured tool call timeout setting.
  • Verify that the knowledge base only associates file data for the current ship inspection number, with no cross-ship data mixed in.
