The guide details how to integrate a service link to the Rollbar Debugging Assistant, an AI-driven tool designed to streamline the process of analyzing and debugging error occurrences without needing direct access to code repositories. By setting up this service link, users can send error details like stack traces directly into an AI chat to receive immediate insights and suggestions for resolution. The setup involves navigating to project settings, creating a new service link under integrations, and adding a URL with placeholders for dynamic data insertion. This integration facilitates a secure and efficient debugging workflow by leveraging existing Rollbar data, eliminating the need for prompt engineering, and focusing AI analysis on specific error occurrences without exposing source code.
