Can I use these logging patterns for non-interactive scripts?

Absolutely. It features TTY detection to automatically strip colors and emojis when the script output is piped to a file or another process.

How do I implement log levels like DEBUG?

The skill provides a pattern using an associative array for log levels and a 'log' function that compares the current LOG_LEVEL variable against the message level.

Does this skill support color in CI environments?

Yes, the skill includes detection logic for environments like GitHub Actions and GitLab CI to ensure colors remain active even in non-interactive shells that support them.

What is the benefit of the GitLab and GitHub specific functions?

These functions use platform-specific escape codes to create collapsible log groups, making long deployment logs much easier to navigate and debug.
