SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Unhandled or mishandled error paths in code are a leading cause of silent production failures, data corruption, and hard-to-debug outages that often go unnoticed until they impact end users. This Skill eliminates that risk by systematically auditing code for error handling anti-patterns before code is shipped to production.

Core Features & Use Cases

  • Multi-Language Error Audit: Scans Python, TypeScript, C#, Java, C, C++, and SQL code for 13 distinct error handling anti-patterns including empty catch blocks, broad exception handling, lost error context, and unhandled async errors.
  • 2026 Best Practice Enforcement: Aligns all findings with modern error handling standards including RFC 9457 for HTTP API error responses, structured logging requirements, proper error cause chaining, and clear differentiation between operational and programmer errors.
  • Use Case Example: A team building a payment processing service can use this Skill to catch bare except blocks that swallow card decline errors, preventing partial-success transactions that are incorrectly marked as successful charges.

Quick Start

Use the error-handler-checker skill to audit all error handling logic in your payment service codebase for unhandled exceptions, missing fallbacks, and anti-patterns that could cause silent production failures.

FAQPage Schema
How do I audit my codebase for unhandled exceptions and silent failure paths?

To audit code for unhandled exceptions and silent failure paths, scan your codebase against 13 error handling anti-patterns including empty catch blocks, broad exception handling, and lost error context. This identifies mishandled paths before production outages.

What are common error handling anti-patterns that cause silent production failures?

Common error handling anti-patterns that cause silent production failures include empty catch blocks, broad exception handling, lost error context, and unhandled async errors. Auditing for these 13 specific patterns eliminates latent incident risks.

Does this error audit support static analysis for Python, TypeScript, and SQL code?

Yes, this error audit performs static analysis across Python, TypeScript, C#, Java, C, C++, and SQL code. It identifies unhandled and mishandled error paths that cause data loss, silent failures, and production outages in these languages.

How do I enforce RFC 9457 compliance for HTTP API error responses?

Enforce RFC 9457 compliance by auditing your HTTP API error responses against 2026 error handling best practices. This ensures structured error logging, proper error cause chaining, and clear differentiation between operational and programmer errors.

What is the best way to catch unhandled async errors before they cause production outages?

The best way to catch unhandled async errors is to perform a static code audit targeting async error handling anti-patterns. This detects missing fallbacks and unhandled promise rejections that lead to silent production failures.

Why does broad exception handling cause data loss in payment processing services?

Broad exception handling causes data loss in payment processing services by swallowing card decline errors inside bare except blocks. This creates partial-success transactions incorrectly marked as successful charges, leading to silent production failures.
