SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires git, curl, make, node, and includes scripts (resource) components.

What problem does it solve?

It removes the friction of manually starting the piper-draw frontend and backend, then finding and opening the correct local URL in your browser.

Core Features & Use Cases

  • Workspace-aware startup: Derives per-workspace ports so multiple piper-draw checkouts can run side by side without collisions.
  • Fast relaunch flow: Detects an already-running server, opens the GUI immediately, and skips unnecessary startup work.
  • Reliable local dev boot: Sources nvm when available, verifies Node 22+, backgrounds the development server, and waits for the frontend to become reachable.
  • Use Case: A developer says they want to open the app, and the skill starts the dev stack, opens the browser, and reports the frontend and backend URLs.

Quick Start

Use the open-gui skill to start the piper-draw development server in the background and open the application in your default browser.

Frequently Asked Questions about open-gui

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I start a FastAPI and Vite development server with one command?▼

To start a FastAPI and Vite development server, the skill backgrounds the make dev process, verifies Node 22+, waits for the frontend to respond, and opens the GUI in your default browser automatically.

Can I run multiple piper-draw workspaces side by side without port conflicts?▼

Yes, you can run multiple workspaces side by side because the startup process derives per-workspace ports, preventing local development server port collisions across different checkouts.

What happens if I try to launch the GUI when the dev server is already running?▼

When the dev server is already running, the skill detects the active session, skips unnecessary startup work, and opens the GUI immediately in your browser for a fast relaunch.

Do I need a specific Node version to launch the Vite frontend and FastAPI backend?▼

Yes, you need Node 22+ to launch the Vite frontend and FastAPI backend, as the skill sources nvm when available and verifies your Node version before booting the server.

Why does my piper-draw local dev boot timeout when opening the GUI?▼

Your local dev boot may timeout if the Vite frontend takes too long to become reachable after backgrounding make dev, causing the skill to report a timeout instead of opening the browser.
