Show HN: Deedglass – An agent said it updated 1 row; Postgres changed 301 (github.com)

Deedglass is a newly announced open-source tool that acts as a safety layer between AI agents and database systems, such as Postgres. It addresses the critical need for verifying the accuracy of operations performed by AI in contexts like healthcare and other sensitive data management. By implementing pre-defined rules for every tool call, Deedglass checks the actual changes made to the database against what the AI agent reported. For instance, it can correct discrepancies—like an AI claiming to update one row while the database reflects 301 changes—by sealing the verified actions in signed records for offline verification and enabling undo capabilities when necessary. This tool is significant for the AI/ML community as it enhances transparency and accountability in AI-driven database interactions, helping to prevent accidental data manipulations that could lead to erroneous outcomes. Deedglass is designed for self-hosting on personal machines without requiring complex setups, making it accessible for developers and teams, especially in healthcare settings where compliance and data integrity are paramount. Using a simple command line interface, developers can initiate Deedglass to secure their AI agents across various coding platforms, thereby reinforcing the safe deployment of AI technologies in critical applications.
