Tool Calling and Plugins for Joint-Stock Bank Intelligent Due Diligence Reports

What the data for this category looks like

Data sources for joint-stock bank intelligent due diligence reports include internal credit files, quarterly/annual financial reports, regulatory submission ledgers, and external credit reporting and industrial and commercial public API interfaces. Data update frequencies differ. Credit files update in real time as customer credit status changes. Financial reports update on a quarterly and annual basis. Regulatory ledgers update with monthly submissions.

Document structures typically include modules such as basic due diligence subject information, detailed financial indicators, risk control rating results, related party transaction records, and collateral contract summaries. Most fields are structured numerical values and text labels. Numerical fields uniformly use ten thousand yuan and hundred million yuan as units. Rating fields use standardized letter grades such as AA and BBB.

How these characteristics impose constraints on tool calling and plugins

Mixed access to multi-source data requires tool plugins to support unified calls for internal interfaces and external APIs. This prevents data format incompatibility issues. Differently timed data updates require differentiated caching configurations. For example, real-time credit data must disable local caching. Quarterly financial report data can use daily caching.

Standardized field units require tool calls to automatically verify parameter unit matching. This prevents parsing errors where values and units do not align. The presence of long documents and multi-modal attachments requires plugin calls to support pagination parsing and chunked processing. This prevents single-call timeouts or memory overflow.

How to set configurations

Configuration ItemRecommended ValueRationale
UPLOAD_FILE_MAX_SIZE500 MBJoint-stock bank due diligence reports often include multi-page financial report scans and attachments. This value covers file upload requirements for most conventional scenarios
TOOL_CALL_TIMEOUT120 secondsA single due diligence report requires calls to multiple tools such as financial parsing, related party query, and risk control rating. This duration covers average cross-interface call latency
PARSE_TABLE_STRICT_MODEEnabledFinancial table fields in due diligence reports have strict unit requirements. Strict mode prevents unit parsing errors and improves structured data accuracy
SESSION_PERSIST_DURATION7 daysJoint-stock bank due diligence processes often span multiple working days. This configuration retains complete session context to ensure consistent tool calling
MAX_TOOL_CALL_STEPS8 timesThe tool calling chain for a single due diligence report typically includes 5-7 steps. This upper limit avoids invalid circular calls while covering full workflow requirements

The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Each case requires specific analysis. It is recommended to test on your own samples before finalizing settings.

Three common configuration mistakes

  • Symptom: A 400 <400> InternalError.Algo.InvalidParameter: Multimodal file size is error is returned when calling multi-modal parsing plugins. Cause: The UPLOAD_FILE_MAX_SIZE configuration was not adjusted, and the uploaded due diligence report scan exceeded the platform default limit.
  • Symptom: Outputs from the tool calling module in a workflow are forcibly returned to the conversation interface and cannot be hidden. Cause: The show_tool_output switch for tool calling was not disabled. The default configuration is enabled.
  • Symptom: Input text "分享" is parsed as "分交" when calling a tool. Cause: The INPUT_NORMALIZE configuration was not enabled. Candidate words from Chinese input methods were not properly truncated, leading to input escaping errors.

How to confirm configurations are set correctly

  • Upload the largest-sized single due diligence report scan, verify that plugin calls have no parameter errors, and adjust UPLOAD_FILE_MAX_SIZE based on actual file sizes.
  • Run a test workflow that includes multiple tool calls, confirm that session context remains consistent across multiple calls, and adjust SESSION_PERSIST_DURATION based on the due diligence process cycle.
  • Input test text containing easily confused words, verify the input parsing result during tool calling, and confirm whether the INPUT_NORMALIZE configuration is suitable for the scenario.
  • Run a test after disabling the tool output switch, confirm that the conversation interface only displays the final conclusion with no intermediate tool calling content.
