Intent

Identify and remove duplicate skills cluttering Claude Code context
Skills Janitor detects cross-scope duplicates (user/plugin overlaps) with Jaccard similarity scoring, surfacing redundant skills that waste token budget and context window space.
Automate cleanup of broken symlinks and empty skill directories
The /janitor-fix command with --prune flag automatically removes broken symlinks and empty directories, eliminating manual cleanup overhead.
Understand which skills consume the most tokens and context
The /janitor-value command combines token count with usage metrics, sorted by waste, helping users prioritize which skills to remove or optimize for efficiency.
Audit skill health and find broken or unused skills
The /janitor-report command inventories all skills across user, project, codex, and plugin scopes, flags broken symlinks, and identifies unused skills consuming context without value.
