What the data for this category looks like
The data sources for packaging and printing intelligent due diligence reports include production ledgers, raw and auxiliary material purchase vouchers, printing quality inspection reports, environmental assessment filing documents, and printing design source files. The data update rhythm adjusts based on the enterprise’s reporting cycle, with no unified fixed frequency. The document structure includes two categories: structured reports and scanned document attachments. Structured report fields cover printing size, single-batch production capacity, raw material loss rate, VOC emission values, etc., with units mostly being millimeters, ten thousand sets, percentage, milligrams per cubic meter. Scanned document attachments are mostly photographed files such as paper quality inspection reports and purchase invoices.
Constraints on Tool Calling and Plugins
The unique data characteristics of packaging and printing due diligence reports impose three clear constraints on the tool calling and plugins link. First, the inclusion of paper scanned document attachments requires plugins to support OCR parsing and multi-format file processing. Without this, key compliance parameters in paper quality inspection reports cannot be extracted. Second, structured fields include physical parameters and compliance indicators with units. Tool calling must retain unit information and complete accurate field mapping to avoid data loss. Third, individual report documents are long and attachments have large file sizes. The context window and parsing duration configuration for tool calling must adapt to the processing needs of long texts and large files to prevent key content from being truncated or parsing failures.
How to Set Configurations
| Configuration Item | Suggested Value | Basis for This Setting |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2048 MB | Packaging and printing due diligence reports include multi-page scanned documents, CAD source files, and raw and auxiliary material quality inspection reports. The size of individual files usually does not exceed 2048 MB |
PARSE_TIMEOUT_SECONDS | 600 seconds | Parsing large scanned documents or complex CAD files requires sufficient processing time to avoid mid-run timeouts |
MCP_TOOL_RETRY_THRESHOLD | 2 times | Address network fluctuations or temporary parsing failures during MCP tool calls, reducing task failure rates |
TOOL_FILE_VAR_ENABLE | Enabled | Support referencing custom variables in upload file parameters of custom workflows, adapting to calling requirements for different report cycles |
PARSE_FILE_ALLOWED_EXTS | pdf,jpg,png,dwg,xlsx | Cover common attachment formats for packaging and printing due diligence reports, including printing design source files, quality inspection scanned documents, and purchase ledgers |
DEFAULT_TIMEOUT | 1200 seconds | When published as an API interface, adapt to the calling wait requirements for long-cycle due diligence data |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: A
504 Gateway Timeouterror is returned when calling MCP tools, or the tool returns an empty result. Cause: ThePARSE_TIMEOUT_SECONDSconfiguration was not adjusted for large packaging and printing files, causing the parsing process to time out and be interrupted. - Symptom: A "file size exceeds limit" prompt appears when uploading files, and due diligence report attachments cannot be submitted. Cause:
UPLOAD_FILE_MAX_SIZEwas not adjusted to a value suitable for packaging and printing attachments, and the default 2 MB limit is still used. - Symptom: Variables cannot be referenced in upload file parameters in custom workflows, making it impossible to batch call due diligence report tools for different cycles. Cause: The
TOOL_FILE_VAR_ENABLEconfiguration was not enabled, restricting the variable reference capability of upload parameters.
How to Confirm Proper Configuration
- Upload a packaging and printing CAD source file or multi-page scanned document, and check if complete fields such as printing size and production capacity are extracted after parsing, with no truncation or data loss.
- Call an MCP tool and set a custom variable as the report cycle parameter, and check if the tool can correctly receive the variable and return due diligence data for the corresponding cycle.
- After publishing as an API interface, set a timeout period of more than 10 minutes, initiate a parsing call for a large file, and check if the call completes normally and returns results.
- View tool call logs, and confirm that the retry mechanism can automatically trigger and recover tasks in a simulated network fluctuation scenario.
