Tool Calling and Plugins for Home Healthcare Regulations

Data Characteristics in this Category

Data sources for home healthcare regulations and SOP documents include laws from regulatory bodies, standards from industry associations, and internal operating procedures based on these guidelines. Update frequency is stable, typically revised when policies change or technology evolves, ranging from months to years. Documents are primarily PDFs and Word files, with a high degree of structure, often including chapters, clauses, and appendices, along with clear numbering systems. Common fields include "device name," "scope of application," "operating steps," "risk warnings," and "maintenance cycle." When measurement units are involved, such as "pressure," "temperature," or "time," they strictly adhere to international units or industry-specific standards. The language in these documents is precise, standardized, and contains many specialized terms.

Constraints Imposed by these Characteristics on Tool Calling and Plugins

The structured nature of home healthcare regulatory documents requires tool calling and plugins to effectively identify chapters and clauses for precise targeting. The stable update frequency allows for periodic data synchronization and caching strategies, eliminating the need for real-time updates and reducing unnecessary resource consumption. Documents contain numerous specialized terms and measurement units, demanding higher model comprehension and parameter extraction capabilities. This may require customized entity recognition models or dictionaries to ensure accurate parameter passing during tool calls. Furthermore, the citation relationships between legal provisions necessitate that plugins support complex knowledge graph queries for knowledge retrieval, providing contextually complete and logically coherent answers. For SOPs involving operating steps, plugins must parse sequential information and convert it into executable instructions or suggestions.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`maxContext`	`4000` tokens	Single queries for home healthcare regulatory documents often involve multiple related clauses, requiring a larger context window to ensure information completeness.
`Recall Count`	`8` items	Regulatory Q&A demands high accuracy. Increasing the recall count appropriately improves the coverage of relevant information and reduces omissions.
`Similarity Threshold`	`0.78`	A high threshold helps filter out low-relevance results, ensuring that recalled regulatory clauses highly match the query intent and avoid misleading information.
`Rerank Return Count`	`3` items	After reranking, the few most relevant items effectively meet the user's need for quick access to core regulatory clauses.
`PARSE_FILE_TIMEOUT_SECONDS`	`300` seconds	Home healthcare documents may contain numerous charts and complex layouts, leading to longer parsing times, which necessitates a longer timeout setting.
`UPLOAD_FILE_MAX_SIZE`	`500` MB	Regulatory documents may contain large attachments and high-resolution images, so the single file size limit should be relaxed to support uploads.

Three Common Mistakes

When calling external APIs, the file format parameter is not correctly encoded or uploaded, resulting in a 400 Bad Request error. This occurs because the file content is not converted to a base64 string or sent using multipart form data.
When using global variables for API parameter assignment, the variable value is empty or the type does not match, leading to tool call failure. This manifests as a 500 Internal Server Error or empty fields, due to improper variable scope or data conversion handling.
After parsing a CSV file, the data does not match the original display, with some rows or columns missing. This is because special characters in the CSV file (such as commas, newlines) are not correctly escaped or quoted according to the RFC 4180 standard.

How to Confirm Correct Configuration

Use FastGPT's debug logs to check if the parameters passed during tool calls match expected values, especially for fields involving specialized terms and measurement units.
For typical regulatory Q&A, execute queries in a test environment and compare the model's answers with relevant clauses in the original documents to confirm accuracy and completeness.
Simulate a regulatory document update scenario by uploading a new version of a file. Check if the knowledge base index updates correctly and verify that Q&A results based on the new document meet expectations.
During tool calls, check if all HTTP request status codes are 200 OK, ensuring successful external API calls and correct data transmission.
