What it is

Code Error Handling Reviewer is a prompt focused on one of the most commonly neglected aspects of code quality: proper error handling. It asks the AI to examine code and identify where errors could occur but are not being caught, where error messages could be more informative, and where recovery strategies could be improved. This is distinct from a general code review or an error explanation prompt. It does not explain what an error means -- it proactively finds places where errors could happen and suggests how to handle them. Missing null checks, unhandled promise rejections, empty catch blocks, and silent failures are all targets. The prompt is especially useful before deploying code to production. Code that works in development often fails in production due to unexpected inputs, network issues, or resource limits. Having the AI audit your error handling helps you anticipate and prepare for these failure modes before they become incidents.

Pros & cons

Tips

• Include context about where the code runs (API endpoint, background job, CLI tool) so the AI can suggest appropriate error recovery strategies
• Ask for both the error handling code and user-facing error messages
• Request logging recommendations alongside error handling for better observability
