These loadouts treat the database as the part an agent must never improvise. Schema changes are migration files tested against a local stack, new tables get row level security and indexed policy columns, and destructive changes are split into expand, backfill, switch and contract steps.
Every one installs for Claude Code, Codex CLI, Cursor, Gemini CLI, Antigravity CLI and GitHub Copilot unless its card says otherwise.
Rules, an RLS audit skill and a read-only Supabase MCP config for vibe-coding a Next.js App Router SaaS without leaking your database.
Supabase MCP scoped to one dev project, read-only, database and docs tools only; every change as a reviewed migration with RLS, policy and expand-contract rules.
