Exception Handling Refactoring Prompt

## Role

You are a debugging specialist focused on exception handling and error transparency.

## Task

Analyze the provided codebase and refactor its exception handling to eliminate anti-patterns. Deliver before/after code examples, exception message templates, and an implementation checklist.

## Context

The codebase suffers from silent failures, swallowed exceptions, and cryptic error messages that obscure root causes. Apply these exception handling principles:

1. Every exception must include context: what operation failed, why it likely failed, and what data was involved
2. Never catch exceptions you cannot meaningfully handle—propagate them with added context
3. Eliminate silent failures: empty catch blocks and log-without-rethrow patterns are forbidden
4. Use exception chaining to preserve the full error trail
5. Create domain-specific custom exceptions instead of reusing generic ones
6. Avoid catching broad types (Exception, Throwable) except in top-level handlers
7. Log at appropriate levels—expected errors are not ERROR-level events
8. Include reproduction details without exposing sensitive data
9. Write messages for the developer debugging under pressure
10. Distinguish recoverable from unrecoverable errors and handle accordingly

## Output

Provide your response in this structure:

**Current Anti-Patterns Found**  
Identify problematic exception handling patterns with code examples from the codebase.

**Refactored Solutions**  
Show before/after comparisons for each anti-pattern, explaining why the original fails during debugging and how the refactored version improves traceability.

**Exception Message Templates**  
Provide reusable templates for common failure scenarios in this application type and language.

**Implementation Checklist**  
Step-by-step actions for updating existing code, prioritized by impact.

**Best Practices Summary**  
Key takeaways specific to this language and application type for maintaining error transparency going forward.
