SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the risk of insecure Supabase deployments for SaaS applications, preventing data leaks, row-level security bypasses, and misconfigured storage that could expose user data or enable cross-tenant access.

Core Features & Use Cases

  • Enforced Row-Level Security: Automatically configures RLS enabled and forced on all user-data tables, with custom JWT org claims for multi-tenant isolation.
  • Secure Storage & Privileged Operations: Sets up storage buckets with policies matching table RLS, and guarded Edge Functions for tasks that require RLS bypass, with proper caller authorization checks.
  • Use Case: For a B2B SaaS app, it configures org-scoped data access, Supavisor transaction pooling for serverless functions, and quarterly backup restore drills to meet compliance requirements.

Quick Start

Use the supabase-data skill to set up a secure, RLS-enforced Supabase data layer for your multi-tenant SaaS application with proper connection pooling and aligned storage policies.

FAQPage Schema
How do I enforce row-level security in Supabase for a multi-tenant SaaS application?

Configure Supabase storage by setting up buckets with policies that match table RLS rules. This ensures storage alignment with row-level security, preventing misconfigured storage from exposing user data or enabling unauthorized cross-tenant file access.

How do I set up Postgres connection pooling in Supabase for serverless functions?

Set up Postgres connection pooling via Supavisor to enable transaction pooling for serverless functions. This prevents performance degradation in multi-tenant SaaS applications by managing database connections efficiently under serverless workloads.

Can I use Supabase Edge Functions to bypass row-level security safely?

Yes, you can use guarded Supabase Edge Functions to safely bypass RLS for privileged operations. This requires implementing proper caller authorization checks to ensure only authorized requests can execute privileged tasks without compromising data security.

What is the best way to prevent data exfiltration in Supabase production environments?

Do indexed RLS policy columns prevent performance degradation in Supabase Postgres? Yes, indexing RLS policy columns prevents performance degradation when querying large datasets. This is required for production-grade Supabase setups to maintain query speed while enforcing row-level security.
