Migration guardrails

Rules for migrating Lovable / Base44 / v0 / Vercel / Bolt imports to Replit. Base44 imports get a call-by-call map in .local/secondary_skills/replit-migration-guardrails/references/base44.md; v0/Vercel imports get a Next.js migration guide in .local/secondary_skills/replit-migration-guardrails/references/vercel.md. Security reasoning: https://blog.replit.com/defense-in-depth-how-replit-secures-every-layer-of-the-vibe-coding-stack.

Rules

  1. Database: Replit PostgreSQL via the javascript_database blueprint. Not Supabase, Firebase, PlanetScale, etc. Reason: the blog post's frontend/backend separation argument — RLS-only apps are the vulnerability class Replit is built to avoid. Schema in shared/schema.ts, IStorage in server/storage.ts, routes under /api/*, then npm run db:push.

  2. Auth: javascript_log_in_with_replit blueprint (Replit Auth). If the user explicitly asks for Clerk, use the clerk-auth skill. Never hand-roll cookie sessions or design login/signup/reset forms. Don't use the strings "Replit" or "Replit Auth" in UI; just "Log in".

  3. Secrets: Live in Replit's secret store. Use the environment-secrets skill's ask_secrets tool to request user-supplied keys, and check_secrets to see what's already set. Never paste keys into code or .env.*. Never expose via VITE_* (that ships to the browser). Scrape nothing from the imported .env; re-request through ask_secrets.

  4. Integrations: For AI, use AI Integrations via the integrations skill (OpenAI / Anthropic / Gemini env vars auto-provisioned, no key from the user). For object storage, use javascript_object_storage. For payments, javascript_stripe / javascript_paypal. For email / SMS / Slack / Notion / etc., search the integrations skill first. Only fall back to ask_secrets if no integration exists. Never call external APIs from the browser.

Talk to the user like a non-technical user

Keep user-facing messages short. Just tell them a migration is running; no enumeration of what surfaces were found, no step-by-step plan, no tool / library / file / blueprint names.

One-liner format: what the app is, that you're migrating it, rough time, whether they need to do anything (ideally "nothing right now").

The per-source reference in references/ has a filled-in template.
