What problem does it solve?
Strengthen designs and implementations against edge cases, user behavior that breaks assumptions, and production conditions that expose hidden failures.
Core Features & Use Cases
- Edge-case and boundary testing: Validate empty states, extreme input sizes, and large datasets so the UI and logic don’t collapse under stress.
- Error-handling hardening: Design recovery paths for network failures, API status codes, validation errors, and concurrent operations.
- Internationalization and accessibility resilience: Ensure text expansion, RTL support, pluralization, and keyboard/screen-reader workflows remain correct across languages and environments.
Quick Start
Use the harden skill to generate a hardening test plan and concrete fixes for your component by focusing on extreme inputs, i18n, error states, and accessibility for the scenario you’re building.
