What problem does it solve? New contributors often struggle with first-time environment setup: wrong Node or Yarn versions, missing environment variables, Corepack failures, and broken local authentication. This Skill walks through the entire LFX One setup interactively, verifying each step before moving on. ## Core Features & Use Cases - Prerequisite Verification: Checks Node.js 22.13+, Yarn 4.9.2+ via Corepack, and Git, with install guidance for each. - Environment Variable Validation: Copies the .env template, pulls credentials from the 1Password vault, and runs a shell script to confirm all critical Auth0 and service variables are populated. - Troubleshooting & Auth Debugging: Diagnoses Corepack errors, port conflicts, stale cookies, and rotated Authelia client secrets for the local k8s auth stack. - Use Case: A new engineer joins the team and asks how to get started. The Skill walks them through cloning the repo, configuring .env from 1Password, running yarn install, starting the dev server, and verifying the login page loads at localhost:4200. ## Quick Start Ask the assistant to walk you through setting up the LFX One development environment from scratch.
