: Consider enhancing the exception class implementationThe implementation is correct and aligns with the PR objectives. However, consider these improvements for better maintainability and usability:
class MissingResourceKindAliasError(Exception): + """Exception raised when a requested resource kind alias is not found. + + Args: + requested_kind: The resource kind that was not found in aliases + """ def __init__(self, requested_kind: str) -> None: + message = f"Resource kind alias '{requested_kind}' not found" + super().__init__(message) self.requested_kind = requested_kind def __repr__(self) -> str: return f"Resource kind alias '{self.requested_kind}' not found" + + def __str__(self) -> str: + return self.__repr__()

: Enhance error handling and documentationThe implementation is correct but could be enhanced for better error reporting and maintainability:
class FailToReadJSONFileError(Exception): + """Exception raised when a JSON file cannot be read. + + Args: + file_name: Path to the JSON file that couldn't be read + original_error: Optional underlying error that caused the failure + """ - def __init__(self, file_name: str) -> None: + def __init__(self, file_name: str, original_error: Exception = None) -> None: + message = f"Failed to read JSON file '{file_name}'" + if original_error: + message += f": {str(original_error)}" + super().__init__(message) self.file_name = file_name + self.original_error = original_error def __repr__(self) -> str: - return f"Can't read file '{self.file_name}'" + return f"Failed to read JSON file '{self.file_name}'" + + def __str__(self) -> str: + return self.__repr__()This enhancement:
- Adds comprehensive documentation
- Captures the underlying error for better debugging
- Provides more specific error messaging
- Maintains consistency with Python's exception handling patterns

: Enhance user feedback for better UXThe message when no resources are found could be more descriptive to help users understand why their query returned no results.
Consider this enhancement:
if not resources_raw_data: - CONSOLE.print(f"No resources found for {resource_kind} {resource_name} {namespace_name}") + message = f"No resources found for kind '{resource_kind}'" + if name: + message += f" with name '{name}'" + if namespace: + message += f" in namespace '{namespace}'" + CONSOLE.print(f"[yellow]{message}[/yellow]") continue

: Consider centralizing error messagesThe error messages are currently scattered throughout the code. Consider centralizing them in a dedicated module (e.g.,
app/messages.py
) to:
- Maintain consistency in messaging
- Enable easier updates and translations
- Reduce duplication
Example structure:
# app/messages.py class ErrorMessages: ALIASES_UPDATE_HELP = "How to update the resource aliases file: {url}" INVALID_RESOURCE_KIND = "[bold red]Error:[/bold red] Not valid resource kind '{kind}'" NO_RESOURCES_FOUND = "No resources found for kind '{kind}'{name_info}{namespace_info}"

: Verify exception handling implementation
Let's verify that these exceptions are properly caught and handled in the codebase:
✅ Verification successful
Exceptions are properly implemented and handled
The exceptions are well-integrated into the codebase:
FailToReadJSONFileError
is properly raised inget_resource_kind_by_alias()
when there's an issue reading the aliases file, with appropriate error messaging and graceful exitMissingResourceKindAliasError
is correctly raised when an invalid resource kind is requested, with helpful user feedback- Both exceptions are caught in the main command loop with appropriate error handling:
FailToReadJSONFileError
triggers system exitMissingResourceKindAliasError
continues the loop for new user input
- The exceptions provide meaningful error messages through their
__repr__
implementations

: LGTM: Clean import of new exception classes
The import statement is well-placed and correctly imports both new exception classes.
261-261
: LGTM: Well-implemented exception handling with helpful messages
The exception raising is well-implemented with:
- Informative error messages that guide users
- Helpful links for updating aliases
- Appropriate exception types for different error cases
