What the Data for This Category Looks Like
Daily documents for this category include pre-press files, imposition sheets, printing process sheets, ink color matching records, first-piece sample approvals, barcode detection, die-cutting and lamination records. Data sources include customer submissions, color management systems, printing press data, ink and substrate batch records, spectrometer and barcode detector outputs. Data updates trigger per order, per batch, or each time a printing plate is replaced. Individual documents contain fields such as customer number, plate version number, color parameters, substrate model, and batch number. Some documents include quantitative detection values with units including color difference values, barcode check codes, and die-cutting accuracy values.
What Constraints These Characteristics Impose on Tool Calling and Plugins
Documents for this category require simultaneous verification of content version, color parameters, and packaging structure. Data update frequency is high, so tool calling must support real-time reading of multi-source heterogeneous data. Each batch of orders corresponds to exclusive documents, so tools must support switching workflows by order dimension to avoid cross-batch data confusion. Quantitative detection data such as barcode and die-cutting accuracy must be accurately matched to fields. Tool calling must fix data mapping rules to prevent audit failure caused by field misalignment. Printing plate errors will be rapidly replicated across an entire production batch, so tool calling must trigger immediately after document upload, with no delayed processing.
How to Configure
This configuration is based on the plugin and tool calling logic of FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow/API tool selection | auto, call only preset tools | This category requires fixed calling of printing document-specific review tools to avoid free-form calls deviating from business logic |
| Workflow/API function-call configuration | mandatory specification, match printing document verification function | Precise calling of tools adapted to this category’s fields and verification rules is required to ensure review covers content, color, and packaging structure |
| Workflow switching trigger rule | Trigger by order batch ID | Data for this category updates per order or plate change, triggering by batch prevents cross-batch data confusion |
| Tool call timeout threshold | 600 seconds | A single printing process sheet needs to read multi-source content such as color management systems and printing press data, requiring sufficient execution time |
| Maximum documents per single tool call | First 10 items | Core documents per order batch do not exceed 10, limiting quantity avoids tool call overload |
| Result verification field matching | Plate version number, color parameters, barcode check code | This category’s review needs to cover content version, color compliance, and packaging identification; accurate field matching improves review accuracy |
Three Common Mistakes
- Symptom: Audit results returned after calling tools include imposition sheet data from other orders. The status code returns 200 but the data is abnormal. Cause: The workflow switching rule is not configured based on order batch ID, and tool calls reuse historically cached workflow configurations.
- Symptom: After plugin configuration is complete, tool calls return a connection failure. Navicat can normally access the data source. Cause: No whitelist permission for the data source is added in the FastGPT plugin network configuration, and port configuration is normal.
- Symptom: When triggering tool calls via API, DOCX documents provided by a URL cannot be parsed, and the error "No valid content found" is returned. Cause: The DOCX format parsing rule is not enabled in the tool configuration, preventing the tool from reading printing process parameters from the target file.
How to Confirm Configuration Is Complete
- Initiate a tool call for a single batch order, verify that returned results only include document data corresponding to that batch, with no cross-batch content.
- Test the connection between the tool and data sources, confirm that configured sources such as color management systems and printing press data can be read normally.
- Upload a test printing process sheet DOCX file, trigger a tool call, confirm that returned results cover core audit fields including plate version, color parameters, and barcode verification.
- Trigger multiple tool calls, confirm that workflows switch correctly based on order batch ID, with no duplicate or incorrect calls.
