Systemix

Systemix keeps your design system from rotting. It watches what you ship, catches where design and code drift apart, proposes a fix with AI, you approve it, and it remembers the reason — so your system gets sharper every release instead of decaying.

Live: https://getsystemix.vercel.app · this site runs on Systemix itself.

Quick start

npx @getsystemix/cli init

Scaffolds an instance into your repo: the validation loop (experiments/), the loop skills in .claude/skills/, and your topology in systemix.config.yaml. Ghost mode by default — it suggests, it never touches your code without approval.

Three doors into the same files: Claude Code slash-command skills, the systemix CLI (systemix experiment new|list|measure|close|learnings), or an MCP connector (experiment_* tools) — pick whichever fits your workflow.

What's in this repo

This is the monorepo behind Systemix:

Path	What it is
src/	The Next.js app — getsystemix.vercel.app, and the reference instance this product dogfoods on itself
packages/cli/	The @getsystemix/cli package — npx @getsystemix/cli init scaffolds an instance into any repo
packages/mcp-server/	The file-backed MCP server exposing the loop (experiment_*, contract_*, HITL) to any MCP client

See packages/cli/README.md for the full CLI command reference.
