name: rls-patterns description: Row Level Security patterns for database operations. Use when writing Prisma/database code, creating API routes that access data, or implementing webhooks. Enforces withUserContext, withAdminContext, or withSystemContext helpers. NEVER use direct prisma calls.

RLS Patterns Skill

Purpose

Enforce Row Level Security (RLS) patterns for all database operations. Ensures data isolation and prevents cross-user data access.

When This Skill Applies

• Writing any Prisma database query
• Creating or modifying API routes that access the database
• Implementing webhook handlers
• Working with user data, payments, subscriptions

Critical Rules

NEVER Do This

Copy// ❌ FORBIDDEN - Direct Prisma calls bypass RLS
const user = await prisma.user.findUnique({ where: { user_id } });

ALWAYS Do This

Copyimport { withUserContext, withAdminContext, withSystemContext } from "@/lib/rls-context";

// ✅ CORRECT - User context for user operations
const user = await withUserContext(prisma, userId, async (client) => {
  return client.user.findUnique({ where: { user_id: userId } });
});

// ✅ CORRECT - System context for webhooks
await withSystemContext(prisma, "webhook", async (client) => {
  return client.webhook_events.create({ data: eventData });
});

Context Helper Reference

Common Patterns

API Route with User Context

Copyexport async function GET() {
  const { userId } = await requireAuth();

  const payments = await withUserContext(prisma, userId, async (client) => {
    return client.payments.findMany({
      where: { user_id: userId },
      orderBy: { created_at: "desc" },
    });
  });

  return NextResponse.json(payments);
}

Admin Pages: Force Dynamic

Copy// REQUIRED for admin pages with RLS
export const dynamic = "force-dynamic";
