Greptile Overview

Summary

The original validation was designed around filesystem naming conventions, but since the Sim knowledge base stores document names directly in the database rather than creating actual files, these constraints were unnecessarily restrictive. The system maintains document metadata in the database, making filesystem-specific character limitations irrelevant to the application's functionality.

This change enhances user experience by providing more flexibility in document naming while maintaining essential constraints like the 255-character length limit, which likely corresponds to database field limitations. The modification is located in the knowledge base tool's document creation functionality, specifically in the parameter validation logic.
