Mobile Stack Skills — AI skill for Claude Code

---

Why this exists

Ask a general-purpose model to "add a paywall to my Expo app" and you get plausible-but-stale advice: deprecated APIs, wrong command order, a leaked API key in the client bundle. This repo fixes that.

It's a set of [Claude Code Agent Skills](https://docs.anthropic.com/claude-code) — structured reference files Claude loads **on demand** while it works. Instead of generic suggestions, Claude pulls the exact file for what you're building and gives you the current SDK version, the correct sequence of commands, and the production pattern that doesn't fall over.

The goal: **go from idea to App Store without Claude having to guess.**

What's inside

Skill	What it covers	Size
`mobile-stack-toolkit`	The full mobile stack — Expo/RN + Flutter + Supabase + Firebase + RevenueCat + AI + push + store + CI/CD	125 files
`supabase-postgres-best-practices`	Deep Postgres rules — indexes, RLS, pooling, migrations, pgvector, pg_cron, pgmq	22 rules

The second skill stands alone — it's useful for **any** Supabase project, mobile or web.
