What the data for this category looks like
Engineering consulting research report data mainly comes from public industry standards issued by housing and urban-rural development departments, project filing archives released by housing and urban-rural development departments of various provinces and cities, special research results from industry institutions such as the China Construction Cost Management Association, and public reports from third-party engineering consulting institutions. There are three update cycles for the data: Policy standards are updated quarterly. Project case data is synchronized monthly. Industry interpretation content is updated every six months. The document structure is fixed, including the cover page, policy basis chapter, core project parameters (including building area, cost indicators, material consumption, etc.), technical plan, risk assessment, and appendix fields such as standard numbers and applicable regions. Common engineering units such as square meters, cubic meters, ten thousand yuan, and tons are used.
Constraints for Tool Calling and Plugins
The structured parameters of engineering consulting research reports are numerous, with unified units and clear update rhythms. Tool calling must support precise matching of numerical fields to avoid parameter deviations caused by fuzzy retrieval. Frequent industry data updates require plugins to support incremental synchronization configuration. This ensures retrieval results always cover the latest policies and project cases. Documents contain a large number of appendix standard numbers and associated project IDs. Tool calling must support associated retrieval by specific fields, and adapt to the parsing and field extraction process for long documents. Project parameters vary slightly across different regions. Regional filtering rules must be configurable during tool calling to narrow the retrieval scope and improve matching accuracy for professional content.
Configuration Recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the average length of a single engineering consulting research report, avoids truncating key content such as core cost and technical parameters |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Matches the parsing time required for appendix fields in long research reports, prevents process termination before parsing is complete |
Number of recalled entries | Top 8 | Balances accuracy and professional information coverage for engineering consulting scenarios, avoids interference from redundant results |
Similarity threshold | 0.75–0.85 | Filters low-relevance general construction documents, focuses on professional consulting research report content |
API_SESSION_EXPIRY | 1800 seconds | Supports multi-turn tool calling sessions in the same scenario, ensures parameters can be passed across turns |
Incremental synchronization interval | 7 days | Adapts to the update rhythm of industry policies and project data, ensures timeliness of retrieval content |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Session state is lost after multiple API calls, and previous round's project parameters cannot be associated. Cause: The
API_SESSION_EXPIRYparameter is not configured, or the value is set too short, causing automatic session expiration. - Symptom: HTTP request components cannot receive numerical fields passed by the plugin, returning the error
Request failed with 400 Bad Request. Cause: No format validation is performed for numerical parameters in engineering consulting research reports (such as cost, building area), causing parameters to not meet the API's type requirements. - Symptom: Appendix standard number fields extracted after PDF parsing are empty. Cause: The
PARSE_FILE_TIMEOUT_SECONDSvalue is set too short, causing termination of the process before parsing of the long document's appendix section is complete.
How to Confirm Successful Configuration
- Initiate a retrieval request for a single engineering consulting research report, check that the returned result context contains complete project parameters and technical plans.
- Initiate 3 consecutive tool calls associated with the same project, confirm that the session state is not lost and parameters can be passed across turns.
- Simulate an industry data update to trigger incremental synchronization, check whether the latest research report content has been added to the vector database.
- Pass numerical parameters to initiate a retrieval, confirm that the HTTP request can carry the parameters normally and return matching results.
