Error Handling Patterns

Use this skill when implementing error handling for features or API endpoints.

Checklist

Exception Handling Rules

• Never use bare except - always specify exception type
• Catch specific exceptions first, then broader ones
• Use domain-specific exception classes with meaningful names
• Log errors before re-raising or returning error responses

Domain-Specific Exceptions

• Create custom exception classes that extend built-in exceptions
• Use meaningful exception names that describe the error condition
• Include helpful error messages with context
