    Generated src/components/ErrorBoundary.tsx
Implemented Sentry.captureException with errorInfo context.

    About This Skill

    Resilient React Error Handling

    Stop the "White Screen of Death" with production-grade React error boundaries. This skill automates the implementation of robust error-catching patterns, ensuring that a single failing component doesn't crash your entire application. It moves beyond basic code snippets by analyzing your project structure, detecting your existing tech stack, and providing a multi-layered defense strategy.

    What it does

    • Smart Detection: Automatically scans package.json for React versions and installed error trackers like Sentry, Datadog RUM, Bugsnag, or Rollbar.
    • Multi-Pattern Support: Generates either modern functional boundaries using react-error-boundary or native class-based components for zero-dependency environments.
    • Context-Aware Fallbacks: Provides specific UI variants for different scenarios, including full-page crash screens for root levels, route-level recovery, and inline "retry" buttons for specific widgets.
    • Automated Integration: Writes the reporting logic required to capture stack traces and event IDs, making it easier for support teams to debug production issues.

    Why use this skill?

    While an AI can write a simple component, this skill acts as an architect. It identifies high-risk areas—like third-party embeds, data tables, and payment flows—and applies a recommended three-layer placement strategy (Root, Route, and Widget). The result is code that includes reset logic, error reporting, and specific developer documentation on what React boundaries don't catch, hardening your app for professional use.
