Skill hygiene involves auditing user-level Claude Code skills under `~/.claude/skills/` to identify unused entries, duplicates, and missing or overly long descriptions. The cleaner reads `SKILL.md` frontmatter and scans transcripts to produce a Markdown report highlighting these issues for focused pruning.

Yes, `rg` (ripgrep) is a required dependency for auditing skills under `~/.claude/skills/`. The cleaner uses it to scan transcripts for references to skills and identify unused entries during the hygiene audit process.

Yes, you can check for missing or overly long descriptions in `SKILL.md` frontmatter. The cleaner reads each frontmatter to extract the name and description, then flags entries with missing descriptions and reports the longest descriptions to help you maintain concise skill metadata.

The best way to clean up duplicate and unused Claude Code skills is to run the cleaner during periodic hygiene sessions. It generates a Markdown-style report with Unused, Duplicates, Missing description, and Longest descriptions sections to inform your pruning and update decisions without deleting entries without confirmation.
