🛡️ Skill: Harden Pro (v1.0.0)

Executive Summary

harden-pro is the guardian of interface stability. While ui-ux-pro focuses on the "Happy Path", harden-pro builds for Production Reality. This skill focuses on error handling, internationalization (text expansion/RTL), responsive text overflow, and network resilience. A hardened interface never breaks, it gracefully adapts.

📋 The Resilience Protocol

1. Extreme Input Test: Simulate very long/short text, special characters, and massive datasets.
2. Error Scenario Audit: Map network failures, API timeouts, and validation errors.
3. i18n Validation: Check for text expansion (German/RTL) and logical properties.
4. Empty State Design: Ensure every feature has a teaching empty state.
5. Sanitization: Validate and sanitize all user-facing inputs.
