The usage-tracker skill enables developers to track and analyze tool or resource usage over time through timestamped logging and reporting. It's designed for generating periodic usage reports, monitoring quotas, and detecting usage trends, but is not suitable for real-time or high-frequency event tracking. Key capabilities include daily/weekly/monthly breakdowns and pattern analysis for building dashboards.

This skill enables parallel task execution in bash using xargs and job control for significant performance gains. It's ideal for batch operations on independent items like multiple files or repositories, particularly for I/O-bound tasks. Developers should use it when order doesn't matter and avoid it for tasks with dependencies or shared resource requirements.

This skill creates organized bash scripts with standardized features like color output, menu systems, and error handling. Use it when building CLI tools or automation scripts to ensure consistent structure and cross-platform support. It helps developers quickly scaffold professional bash scripts with built-in best practices.

This skill parses simple key=value configuration files, supporting comments, empty lines, and quoted values. It's useful when you need to read configuration data from files into an associative array in bash scripts. Developers should use this for handling basic configuration parsing tasks in their shell scripts.
