💡 What: Improved the empty state message for the checkpoint list command to include actionable instructions (Use 'checkpoint create <name>' to create one.) rather than just a dead-end "No checkpoints found." message.

🎯 Why: To prevent users from hitting a dead end and improve the overall CLI UX by guiding them on how to resolve the empty state. This makes the interface more intuitive and friendly.

📸 Before/After:
Before:

$ uv run python-learning checkpoint list
No checkpoints found.

After:

$ uv run python-learning checkpoint list
No checkpoints found. Use 'checkpoint create <name>' to create one.

Accessibility: This improves cognitive accessibility and general usability by explicitly instructing the user on the next possible actions.

Code Review

This pull request enhances the user experience for the checkpoint list command by providing a helpful message that guides users on how to create a checkpoint when none are found. The review feedback suggests an improvement to this new message, noting that the command string checkpoint create <name> is hardcoded. It recommends extracting this string into a variable or using constants to improve maintainability and prevent the message from becoming outdated if the command structure changes in the future.

While this new message is a great UX improvement, it hardcodes the command string checkpoint create <name>. If the command structure changes in the future, this message could become outdated and misleading.

To improve maintainability, it would be better to define constants for sub-command names (e.g., CREATE_CMD = 'create') and use them to construct user-facing messages consistently across the CLI.

As a smaller step in that direction, the suggested change extracts the command string into a variable to make it more explicit and easier to change.

Suggested change
output_fn(
"No checkpoints found. "
"Use 'checkpoint create <name>' to create one."
)
create_command_usage = "checkpoint create <name>"
output_fn(
f"No checkpoints found. Use '{create_command_usage}' to create one."
)
