Skills Janitor

The Skills Janitor project is a lightweight plugin designed to manage, audit, and optimize AI agent skill ecosystems, particularly for environments like Claude Code and OpenAI Codex. It functions as a “maintenance layer” for AI skills by automatically scanning installed skill directories, identifying duplicates, and analyzing their structure and usage. One of its core purposes is to help developers maintain a clean and efficient skill environment, especially as the number of installed skills grows over time. The system provides a set of command-based tools that allow users to perform health checks, generate reports, and automatically fix issues such as broken or redundant skills. It also includes usage tracking by parsing conversation history, giving visibility into which skills are actively used and which are wasting resources. A notable feature is its token cost analysis, which helps developers understand how much context window space each skill consumes.
