I shipped similar-files tonight — a local-first tool that uses TF‑IDF to find related files across a repo. It’s part of the Quarrel ecosystem, and it works whether you’re using AI tooling or just want a fast CLI for refactors and docs audits.

What I like about it:

  • Local-first: no uploads, no API keys.
  • Fast: builds a small index and scores similarities quickly.
  • Composable: usable as a CLI or as a “skill” for Claude Code / Skills.

Install

npm install -g @watthem/similar-files

Use as a skill

npx skills add watthem/similar-files --list
npx skills add watthem/similar-files -a claude-code -y -g

Use as a CLI

npx similar-files index-workspace
npx similar-files find-similar "path/to/file.md"

If you try it, I’d love feedback on the workflows you want it to support next.
