Environment Management

Quick Guide: Per-app .env files (apps/client-next/.env). Framework-specific prefixes (NEXTPUBLIC_, VITE__). Zod validation at startup. Maintain .env.example templates. Never commit secrets (.gitignore). Environment-based feature flags.

CRITICAL: Before Using This Skill

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

(You MUST validate ALL environment variables with Zod at application startup)

(You MUST use framework-specific prefixes for client-side variables - NEXTPUBLIC* for Next.js, VITE_* for Vite)

(You MUST maintain .env.example templates with ALL required variables documented)

(You MUST never commit secrets to version control - use .env.local and CI secrets)
