Resilience

Harden your application with error handling, input validation, retry logic, and defense-in-depth patterns that keep your system running under adverse conditions.

Features

• Error Boundary Design — Implements structured error handling with fallback UIs and recovery paths
• Input Validation — Adds comprehensive validation layers with sanitization for all user inputs
• Retry & Circuit Breaker — Configures retry policies with exponential backoff and circuit breaker patterns
• Edge Case Coverage — Identifies and handles null states, empty arrays, network failures, and race conditions
• i18n Hardening — Validates string handling for Unicode, RTL text, and locale-specific formatting

Quick Start

Usage

# Audit a module for missing error handling
/resilience audit src/api/

# Add retry logic to HTTP client calls
/resilience harden --pattern retry --target src/services/api.ts

How It Works

Analyzes your code paths to identify unhandled error scenarios, missing validation, and fragile assumptions. Generates defensive code patterns including try-catch boundaries, input sanitization, timeout handling, and graceful degradation. Each hardening pattern follows established resilience engineering principles.

Compatibility

Works with Claude Code, Codex, Gemini CLI, Cursor, Windsurf, and Aider.
