Skillhealth: Find Claude Code skills you never use and what they cost (github.com)

Skillhealth has launched a powerful tool that allows users to manage and optimize their Claude Code skills. This tool provides a comprehensive overview of installed skills, detailing their usage frequency, operational status, and associated costs in tokens. The innovative "live cockpit" interface visualizes skill performance and generates actionable diagnostics to fix broken links or inefficient skills. Users can view a heat map indicating whether skills are active (“hot”), rare (“warm”), inactive (“cold”), or completely unused (“dead”), and make real-time adjustments that automatically update the display. The significance of Skillhealth lies in its ability to streamline workflow for developers working with AI and machine learning environments. Skills often accumulate without users realizing which are actively contributing to their projects and which are merely consuming resources. By leveraging real transcript data to assess skill performance, Skillhealth empowers users to optimize their workspace, reducing token costs and improving productivity. The tool is local-only, ensuring privacy without sacrificing functionality, and supports integration with continuous integration workflows through JSON outputs and markdown reports. Future plans include expanding capabilities to support Codex and Gemini CLI, further enhancing its utility in the AI/ML community.
