Create error boundaries, error handling, and fallback UIs for React applications. Use when implementing error handling, creating fallback components, or setting up error reporting.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Error Boundary Creator Add resilient error handling to React and Next.js apps: error boundaries, fallback UIs, async error handling, and error reporting. ## Workflow 1. Identify error-prone areas: async operations, third-party integrations, and route-level entry points. 2. Wrap components in an error boundary. Use a class boundary or the `react-error-boundary` library. See references/class-boundaries.md. 3. For Next.js App Router, add the relevant `error.tsx`, `global-error.tsx`, and `not-found.tsx` segment files. See references/nextjs-error-handling.md. 4. Handle errors that boundaries miss (event handlers, promises) and wire up reporting. See references/async-and-reporting.md. 5. Design fallback UIs with `role="alert"` and a recovery action (reset or reload). 6. Route caught errors to a single reporting sink and test error states before shipping. ## Contents - references/class-boundaries.md — Basic, resettable, and `react-error-boundary` patterns. - references/nextjs-error-handling.md — App Router `error.tsx`, `global-error.tsx`, `not-found.tsx`. - references/async-and-reporting.md — `useAsync` hook and the `reportError` integration module. ## Best Practices …

How to install
mdr add onewave-ai/claude-skills/error-boundary-creator@sha256:e7db3d691f26f5bcThe line at the top of this page pins the label git:20260608.d82d20f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
