Tool Calling and Plugins for Monoclonal Antibody Regulations

Data Characteristics

Monoclonal antibody (mAb) regulation and SOP documents originate from internal pharmaceutical quality management systems, R&D records, production batch files, and regulatory guidelines. Update frequency depends on drug development stages, manufacturing process changes, and regulatory policy adjustments. Updates are typically quarterly or annually, and sometimes more frequently. Document formats are primarily PDF, Word, or internal knowledge base pages. Content structure is complex, containing extensive specialized terminology, diagrams, and cross-references. Common fields include batch number, production date, expiration date, quality control indicators (e.g., purity, potency, endotoxin content), test methods, operating procedures, equipment parameters, and personnel qualification requirements. Units involve physical quantities (e.g., concentration μg/mL, volume mL), time (min, h), and biological potency (IU, U/mg).

Constraints Imposed by These Characteristics on Tool Calling and Plugins

The complexity and specialized nature of mAb regulation documents demand robust semantic understanding and multimodal processing capabilities from tool calling and plugins. The uncertain document update frequency makes real-time data synchronization and version management critical. Detailed operating procedures and parameters in SOPs require tools to precisely extract and convert them into executable instructions. For example, "incubate for 30 minutes" should parse as time: 30, unit: "minutes". Extensive specialized terminology and abbreviations increase model comprehension difficulty, necessitating customized glossaries or domain model support. Furthermore, cross-references between documents require plugins to build effective knowledge graphs and perform associated queries, ensuring comprehensive and accurate answers. For scenarios involving numerical calculations or state judgments, plugins must call external calculation tools or logical judgment modules.

Configuration Recommendations

Configuration Item	Recommended Value	Rationale
`parserConfig.chunkSize`	`800–1200 characters`	Balances paragraph length and semantic integrity in mAb documents, preventing context disruption during splitting.
`parserConfig.overlapSize`	`100 characters`	Ensures sufficient overlap between adjacent chunks to maintain context and handle cross-paragraph semantics.
`retrieverConfig.topK`	`top 5–8 entries`	Regulatory Q&A demands high accuracy; recalling more relevant context increases hit rate.
`toolCallTimeoutSeconds`	`60 seconds`	Most external API responses are within tens of seconds; this allows enough time for complex computations or data queries.
`api.max_retries`	`3 times`	Handles network fluctuations or momentary external service failures, increasing tool call success rate.
`embeddingModel`	`text-embedding-ada-002` or higher	Improves the accuracy of vector representations for specialized terminology and complex sentences, enhancing retrieval quality.

Common Pitfalls

Tool call returns 400 Bad Request or getaddrinfo ENOTFOUND: This usually indicates an incorrect baseURL or endpoint in the tool configuration, preventing connection to the target service, or that the request body parameters do not meet external API requirements.
Model errors with Messages with role 'tool' must be a response to a preceding message when code execution is needed: This indicates that the tool calling stage failed to correctly capture or process the output of the external code execution environment, interrupting the subsequent conversational flow.
Significant discrepancies between online dialogue and API call results, even with stream set to false and detail set to true: During API calls, tool_code might not be correctly parsed or executed, or external tool responses might not be effectively integrated into the final result, leading to missing information.

How to Verify Correct Configuration

For typical SOP questions involving numerical calculations or state judgments, observe whether the AI platform correctly calls external tools and returns calculation results or judgment conclusions.
Check logs for successful tool_code execution records and verify that tool_output matches the expected format.
For complex questions involving cross-references or multi-step instructions within documents, verify that the AI platform can provide complete and logically clear answers through multiple tool calls or knowledge graph queries.
By comparing the same questions across different versions of SOPs, confirm that the platform can identify and cite the latest or specified version of the regulatory content, demonstrating version management capability.
