Skill UI

This SDK enables Java developers to build real-time, scalable web applications using Azure Web PubSub. It leverages WebSocket-based messaging to implement critical features such as live chat applications, instant server-to-client push notifications, and real-time data synchronization. Key functionalities include targeted message delivery (to all, groups, or specific users), connection management, and secure client access token generation.

This skill implements core Customer.io platform features, enabling sophisticated customer communication workflows. Key functionalities include sending transactional messages (e.g., receipts, password resets) and push notifications, executing API-triggered broadcasts to defined segments, and managing user attributes to dynamically drive segment membership. Ideal for building advanced, data-driven marketing automation and customer lifecycle management systems.

A robust internal utility for integrating system status updates with Feishu/Lark. It allows other skills to send structured notifications (e.g., experiment complete, checkpoint waiting, review scores) via webhooks. Supports both 'Push only' (fire-and-forget) and 'Interactive' (bidirectional polling) modes, guaranteeing zero side effects if configuration is missing.

Comprehensive guide for implementing Firebase Cloud Messaging (FCM) in Flutter applications. Learn how to set up push notifications across iOS, Android, and Web, manage permissions, handle incoming messages in foreground, background, and terminated states, and properly manage FCM token lifecycles.

This skill guides developers on implementing event-driven logic for Hex CI/CD workflows. Since Hex does not provide native push webhooks, this method demonstrates how to poll run statuses using callbacks (e.g., TypeScript) to reliably detect task completion or failure. It is essential for integrating Hex pipelines with external services like Slack or custom notification systems.

A guide on handling asynchronous operations and event notifications for the Grammarly API. Since Grammarly does not provide native push webhooks, this skill demonstrates techniques for implementing polling mechanisms (e.g., for plagiarism detection) and building a robust event bus to reliably handle streamed results, such as score completion or AI content detection alerts.
