Code Review
This pull request implements the "Actionable Empty States" principle by updating the checkpoint list command to provide actionable instructions when no checkpoints are found. A new test was added to verify this behavior. The review suggests refactoring the hardcoded empty state message into a constant to improve maintainability and avoid duplication between the implementation and the test, adhering to the DRY principle. It also recommends a more precise assertion in the test.

The command name create is hardcoded in this message. This can lead to inconsistencies if the command is ever renamed, as the change would need to be made in multiple places (e.g., the argument parser definition). This also leads to duplication of the message string in the test suite. To improve maintainability, consider defining a constant for the command name and/or the full message. This would ensure the implementation, help text, and tests stay in sync.

- Hardcoded strings for identifiers or messages that are used in multiple places or are likely to change can make code difficult to maintain. They should be defined as constants to improve maintainability and avoid duplication.

This assertion duplicates the output string from cli.py. This makes the code more brittle, as any change to the message will require updates in both the implementation and the test. It would be better to define this message as a constant in cli.py, import it here, and use it in the assertion. This follows the Don't Repeat Yourself (DRY) principle and makes your tests more maintainable.
Additionally, using in for assertion is less precise than an equality check. Since the command should only print this one line and exit, a more robust assertion would be:
assert output.strip() == EXPECTED_MESSAGE_CONSTANTReferences
- Don't Repeat Yourself (DRY): Avoid duplicating information or logic. In this case, the output message string is duplicated between the implementation and the test code, making the code harder to maintain.

💡 What
Updated the empty state message for the
checkpoint listCLI command to be actionable. Instead of just saying "No checkpoints found.", it now says "No checkpoints found. Create one using 'checkpoint create '."🎯 Why
In CLI applications, empty states can leave users at a dead end, unsure of what command to run next. Adding the exact command required to resolve the empty state reduces cognitive load and provides a much friendlier, more intuitive user experience.

♿ Accessibility
Improves general usability and discoverability of commands for all users, particularly beginners who may not remember the exact syntax for creating a checkpoint.
