Curated Works

Deadweight

A VS Code extension that finds unused dependencies, dead files, and exports โ€” and removes them safely, with a preview and one-click undo.

  • A safe-to-delete score for every finding, built from knip, depcheck, and its own import graph agreeing.
  • Review & Remove with a preview, verified by your own type check, build, and tests โ€” rolled back if anything breaks.
  • An interactive connection graph and blast radius for any file, fully offline.
  • Ships an MCP server for AI agents and a GitHub Action that guards every pull request.

  • Time, words, quote, and zen modes, with punctuation and numbers on demand.
  • Live wpm, accuracy, raw speed, and character breakdown as you type.
  • An on-screen mechanical keyboard with switch audio behind every press.
