Tool Calling and Plugins for Biopharmaceutical Equipment

Data Characteristics for This Category

Biopharmaceutical equipment registration documents draw from diverse data sources. These primarily include equipment manuals, technical parameter tables, validation reports, risk assessment files, and clinical trial data. Documents typically exist in formats like PDF, DOCX, or XLSX. Some data may reside in specialized Quality Management Systems (QMS). Data update frequency is irregular, driven by equipment iterations, regulatory revisions, and defect reports. Document structures usually contain fixed sections such as product overview, technical specifications, quality standards, operating procedures, and maintenance manuals. Fields and units are highly specialized. For example, "sterilization temperature" is typically expressed in Celsius (℃) or Fahrenheit (℉), "flow rate" in liters/minute (L/min) or milliliters/second (mL/s), and "pressure" in megapascals (MPa) or pounds/square inch (psi). These often include specific testing methods and tolerance ranges.

Constraints Imposed by These Characteristics on "Tool Calling and Plugins"

The data diversity and specialization of biopharmaceutical equipment documentation require tool calling and plugins to effectively process multiple file types. They must accurately parse specialized terminology and units. Irregular update frequencies mean the system needs to support incremental updates and version management, ensuring the use of the latest registration data for Q&A or document generation. Complex document structures challenge information extraction accuracy. Plugins need advanced text structure understanding to correctly identify content in different sections. Specialized fields and units demand standardized data processing within tool calls, such as unit conversion or range validation, to prevent errors from inconsistent data formats. Furthermore, due to the strict nature of registration documents, tool call results must be traceable to specific locations in the original documents to meet compliance requirements.

Configuration Strategy

Configuration Item	Suggested Value	Rationale
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Most equipment technical documents are lengthy and require sufficient time for parsing.
`Chunk size` (Segment Length)	`800–1200 characters`	Balances contextual completeness and retrieval efficiency, avoiding overly long segments that dilute key information.
`Recall count` (Recall Count)	`Top 8`	Ensures coverage of multiple relevant sections or parameters in equipment registration documents, improving accuracy.
`Similarity threshold` (Similarity Threshold)	`0.75`	Filters out irrelevant recall results, enhancing answer precision and reducing noise.
`Rerank result count` (Rerank Return Count)	`Top 3`	Focuses on the most relevant recall results, further optimizing LLM input and reducing model hallucinations.
`ENABLE_HISTORY_MESSAGES`	`true`	Biopharmaceutical registration document preparation often involves multi-turn questioning. Retaining historical context helps improve coherence.

Three Common Pitfalls

API call responses do not include knowledge base content. This occurs because the appId or chatId parameters are not passed correctly, preventing the system from associating with the corresponding knowledge base.
Tool calling plugin execution fails with a 400 Bad Request status code. This happens when the JSON parameter format passed to the external API is incorrect, preventing the external service from parsing it.
Errors appear in professional terms or units in the answer, such as misidentifying "L/min" as "ml/s." This is due to a lack of unit standardization or dictionary mapping during the data preprocessing stage.

How to Confirm Correct Configuration

Test the conversational application through the FastGPT interface. Confirm it accurately cites original text snippets from the knowledge base when answering questions involving equipment parameters or regulatory requirements.
Invoke the conversational application using the API interface. Observe if the returned JSON structure includes the knowledge_sources field and check if its content aligns with the expected knowledge base association.
For specific professional questions, such as "What is the maximum operating pressure of a certain bioreactor model?", verify that the tool calling plugin triggers correctly, retrieves accurate numerical values from external systems, and that the units are correct.
