My AI agent kept waiting on me. I built a VS Code extension to fix that (github.com)

A new VS Code extension, Notification Bell, has been launched to enhance user interaction with terminal-based AI agents by sending audio alerts and OS notifications when they require attention. This tool is particularly significant for developers working with various AI interfaces like Claude Code and Gemini CLI, as it addresses the common issue of missing prompts during long-running tasks when users switch windows. Notification Bell not only plays a sound instantly when an AI agent halts for input but also features a reminder escalation system that re-alerts users if they do not respond in a timely manner. Technical details include minimal setup requirements, support for multiple operating systems (macOS, Linux, and Windows), and configurable regex patterns to match specific terminal outputs. The extension integrates directly with Claude Code for seamless operation even when VS Code is out of focus, ensuring that development work remains uninterrupted while keeping users informed. This is a critical advancement in optimizing developer workflow and maintaining the responsiveness of AI agents, ultimately enhancing the utility and user experience in AI/ML environments.
