 ## Development Server
 - **Start dev server**: `./dev-server.sh start` (web mode with hot reloading)
 - **Stop dev server**: `./dev-server.sh stop`
+- **Restart dev server**: `./dev-server.sh restart` (needed for static file changes)
 - **Check status**: `./dev-server.sh status`
 - **View logs**: `./dev-server.sh logs`
 
+**Note**: Hot reloading works for Java code changes. Static files (HTML, CSS, JS) in `src/main/resources/static/` require being "built" (copied to classpath) to trigger live reload - when running from command line with Gradle, this typically requires a server restart to see changes.
+
 ## Code Style Guidelines
 - **Package**: Use `com.larseckart` root package
 - **Imports**: Group imports (standard library, third-party, then local), alphabetically within groups

 ## Architecture Overview
 
 This is a Java-based conversational AI agent that communicates with the Anthropic Claude API. The application follows a hexagonal architecture with clear separation between business logic and I/O adapters.
