Catch specific exception types

Avoid using broad exception handlers like except Exception: or bare except:. Instead, catch specific exception types that you expect and can handle meaningfully. This makes code more maintainable by:

1. Preventing bugs from being silently masked
2. Making error handling intentions clear
3. Improving debugging by preserving stack traces

Example:

# Bad - catches and hides all errors
try:
    result = json.loads(args.compilation_config)
except Exception as e:
    logger.error(f"Error: {e}")
    return None

# Good - handles specific expected error
try:
    result = json.loads(args.compilation_config)
except json.JSONDecodeError as e:
    logger.error(f"Invalid JSON configuration: {e}")
    raise ValueError(f"Configuration must be valid JSON: {e}") from e

When catching multiple exceptions, order them from most specific to most general. If you must catch a broad exception (e.g., for API boundaries), log the full exception details and consider re-raising or wrapping in a domain-specific error.
