Claude Code marketplace MIT core Independent No framework wrap

Tools for Claude Code
power users.

A curated matrix of opinionated plugins for real workflows — schema sync, token budgets, PRD breakdown, and more. Each one production-grade, not a GitHub repo dump.

# In Claude Code, add the marketplace once: /plugin marketplace add duolaAmengweb3/duolakit # Then install whatever you need: /plugin install hello@duolakit /plugin install openapi-guardian@duolakit # coming soon

The matrix

Numbered, versioned, independently maintained.

hello

Live

Sanity-check plugin. Says hello back when you run /duolakit-hello. Use this to verify the install pipeline works end-to-end before installing the real ones.

What "production-grade" means here

Out of 9,000+ Claude Code plugins, ~100 are production-ready. duolakit aims to be in that 100.

  • Unit tests + a 30-second demo video, every plugin
  • Bilingual README (中文 + English)
  • Free MIT core forever — no rug-pull to paid
  • Clear Pro license boundary, separately listed
  • Monthly release cadence; issues answered within 30 days
  • One author, one brand — accountability not committee
