    Add Realtime Features Automatically

    Example session with this skill installed

    Add live notifications to my Next.js SaaS application.

    • Read your context and instructions
    • Compiled the add realtime features
    • Generated the UI component

    Project Detected
    Next.js TypeScript application with session authentication and PostgreSQL

    Real-Time Feature Added

    • Live in-app notification updates
    • notification.created event
    • Authenticated Server-Sent Events stream

    Access Controls

    • The server resolves the user identity from the existing authenticated session
    • Each stream returns only notifications belonging to the authenticated user
    • Client-supplied user identifiers are ignored

    Reliability Controls

    • The client reconnects using bounded exponential backoff
    • Duplicate notification events are ignored using event identifiers
    • Event listeners and connections are closed when the component unmounts

    Files Modified

    • app/api/notifications/stream/route.ts
    • lib/notifications/eventService.ts
    • components/NotificationProvider.tsx
    • components/NotificationBell.tsx
    • tests/notificationStream.test.ts
    • .env.example

    Commands Executed

    • npm run typecheck
    • npm test
    • npm run build

    Validation Result
    Type checking, tests, and the production build completed successfully. Authorized delivery, unauthorized rejection, duplicate handling, and connection cleanup tests passed.

    How to Test
    Start the application, sign in with a local test account, open the notification panel, and create a test notification through the existing local API.

    Scaling Status
    Validated for one application instance. Distributed event delivery was not configured.

    Important Notes
    Use a shared pub/sub system before running multiple application instances. The notification stream does not expose session data or notification records belonging to other users.

    About this skill

    Add Realtime Features Automatically is a bounded ToolForge Labs workflow. Automatically add secure real-time features to existing applications. This skill detects your stack, selects WebSockets or Server-Sent Events, creates authenticated connections, adds reconnection and failure handling, and validates the implementation. ✔ Live notifications and dashboards ✔ Chat and presence features ✔ Job progress updates ✔ WebSocket or SSE integration ✔ Tests and safe validation Perfect for SaaS apps, dashboards, collaboration tools, and live services. The skill works from supplied repository files or partial evidence, separates verified facts from assumptions, avoids invented execution claims, and provides concrete next steps plus deterministic validation where possible.

    Requires an existing project workspace. Multi-instance scaling (Redis/PubSub) is implemented but cannot be verified in local-only environments. Production provider setup requires manual approval.

    What's inside

    Frequently Asked Questions

    The skill automatically analyzes your current tech stack (e.g., Node.js/React or Python/Vue) to determine whether WebSockets or Server-Sent Events (SSE) are better suited for your infrastructure, then builds the secure connection logic for you.

    Yes, the skill is designed to integrate with your existing session-based or token-based authentication middleware, ensuring that only authorized users can subscribe to specific data channels or rooms.

    You receive the full implementation for both the server-side connection handlers and the frontend client logic, including essential lifecycle features like heartbeat monitoring and automatic reconnection with exponential backoff.

    The skill is compatible with major backend languages including Node.js, Python, Go, and Ruby, and works seamlessly with popular frontend frameworks like React and Vue, as well as vanilla JavaScript.

    While it handles the logic for real-time communication, it cannot automatically configure multi-server scaling tools like Redis or third-party messaging providers without existing access to that infrastructure.

    Unlike generic AI prompts, this skill enforces strict connection lifecycle management to prevent memory leaks and "ghost" listeners that can crash your server or slow down your client.
