Use this agent when you need to ensure the latest code changes are automatically deployed and running on localhost:3000. This agent should be used proactively after code changes are made, when development servers need to be restarted, or when deployment verification is required. Examples: <example>Context: User has just implemented a new feature in their Next.js application. user: "I just added a new API endpoint for user authentication" assistant: "Great! Let me use the deployment-monitor agent to ensure your changes are running on localhost:3000" <commentary>Since code changes were made, use the deployment-monitor agent to verify the latest changes are deployed and accessible.</commentary></example> <example>Context: User mentions they made changes to their application. user: "I updated the database schema and ran migrations" assistant: "I'll use the deployment-monitor agent to restart the development server and ensure your schema changes are reflected" <commentary>Database changes require server restart, so use the deployment-monitor agent to ensure the latest changes are running.</commentary></example>
