Prompt Refiner

A local-first prompt-quality workspace. Write one request, optionally choose a prompt type, then copy a refined prompt or inspect its portable JSON contract.

Run locally

npm install
npm run dev

Open http://localhost:3000. Set any control to None to keep it out of the JSON output. The theme toggle switches between a white light mode and black dark mode.

Production

npm run build
npm start

The separate MCP server is in ../prompt_builder_mcp.
