Redlight Greenlight is a native macOS menu bar application designed specifically for developers using Claude Code. The app serves as a convenient interface for managing permission requests that arise when Claude Code needs approval to execute certain actions or access specific resources during development workflows.

The primary feature is a floating overlay that automatically appears whenever Claude Code requires permission approval. This overlay displays the permission request prominently on screen, allowing users to see exactly what Claude is asking to do. Users can then accept or reject the permission request directly through the overlay interface without needing to switch applications.

The app works by monitoring Claude Code activity in the background and detecting when permission prompts are triggered. When a request occurs, Redlight Greenlight presents it in a non-intrusive floating window that stays on top of other applications. This approach eliminates the need to constantly switch back to the terminal window where Claude Code is running.

The main benefit is uninterrupted workflow efficiency - developers can continue working in their primary application (such as Safari, Notes, or other development tools) while still being able to respond to Claude Code permission requests instantly. This saves time and reduces context switching, which is particularly valuable during intensive coding sessions.

The target users are macOS developers who work with Claude Code and frequently encounter permission requests. The app requires macOS 13+ and supports both Intel and Apple Silicon processors. It integrates seamlessly with Claude Code's existing permission system without requiring additional configuration.
