What is cuihua-error-handler?
cuihua-error-handler is a specialized tool within the Openclaw Skills ecosystem that empowers developers to build resilient, bulletproof systems. It addresses the common reality where poor error handling leads to 80% of production issues. By automatically detecting missing try/catch blocks and identifying swallowed errors, this skill ensures that silent failures and unhandled rejections no longer crash your services.
Beyond simple detection, it helps developers implement sophisticated patterns such as circuit breakers, exponential backoff retries, and graceful degradation. This ensures that your application remains functional even when third-party dependencies or internal services fail, making it an essential addition for those using Openclaw Skills to maintain high reliability.
cuihua-error-handler Use Cases
- Scanning entire directories to detect async functions lacking proper try/catch blocks.
- Automating the generation of domain-specific error types and structured logging.
- Implementing circuit breaker patterns to prevent cascading failures in microservices.
- Adding exponential backoff retry logic to fragile network or external API calls.
- Creating graceful degradation fallbacks to return cached or default data during service outages.
How cuihua-error-handler Works
- The Openclaw Skills agent scans the codebase to perform an error coverage analysis, identifying unprotected logic.
- It categorizes risks into Critical, Medium, and Weak based on the context of the code (e.g., financial transactions vs. logging).
- Based on user prompts, the agent injects tailored error handling code, including custom error classes and validation logic.
- It integrates advanced resilience patterns like retry mechanisms and circuit breakers based on the configuration provided.
- Finally, it generates a comprehensive coverage report to track improvements in system reliability.
cuihua-error-handler Setup
To get started with this skill, ensure you have Node.js installed. You can configure your project by creating a .errorhandlerrc.json file in your root directory.
# Analyze your current project coverage
openclaw run cuihua-error-handler "Check error handling coverage in src/"
# Protect a specific file or function
openclaw run cuihua-error-handler "Add error handling to getUserById in api/users.js"
cuihua-error-handler Data Schema & Taxonomy
The skill manages its operations through a configuration file and produces structured reports as follows:
| Component | Description |
|---|---|
| .errorhandlerrc.json | Main configuration file for coverage targets, retry patterns, and custom error classes. |
| Coverage Report | A Markdown summary of files analyzed, missing try/catch counts, and risk-based recommendations. |
| Custom Errors | Built-in classes like ValidationError, NotFoundError, and ServiceUnavailableError for structured responses. |
| Patterns | Logic for CircuitBreaker, retryWithBackoff, and fallback mechanisms. |
cuihua-error-handler Advanced Features
- CI/CD integration to fail builds if error handling coverage drops below a defined threshold.
- Smart error type detection that differentiates between network timeouts, HTTP errors, and JSON parsing failures.
- Circuit breaker monitoring with failure rate thresholds and automatic recovery states.
- Multi-agent support for team-wide error handling policies.
- Automatic transaction rollback generation for database-related errors.
