What problem does it solve?

This Skill addresses the challenge of building VS Code extensions where certain services might not be available immediately or at all, ensuring the extension remains functional and degrades gracefully.

Core Features & Use Cases

• Late-Binding: Services are injected via setters rather than constructors, allowing the tree view to initialize even if the service isn't ready.
• Robust Error Handling: Uses try/catch blocks and checks for service existence to prevent errors from crashing the UI.
• Interface-First Design: Promotes modularity by defining contracts in models, decoupling the tree view from concrete service implementations.
• Use Case: A VS Code extension that displays GitHub issues assigned to team members. If the GitHub API service is temporarily unavailable or not yet authenticated, the tree view will still load, perhaps showing a message indicating the service is offline, rather than failing entirely.

Quick Start

Implement the late-binding pattern by exposing a setService() method in your VS Code tree provider class.
