promptxl rls workflow: Build MVP First, Add RLS Later

Introduction — What Is the promptxl rls workflow and Why It Works

The promptxl rls workflow improves development speed by delaying Row Level Security until a working MVP exists. Initially, the system disables RLS to ensure AI-generated CRUD queries run without policy denials. As a result, developers can prototype freely. After that, ownership columns like user_id and organization_id are added. Then, Row Level Security is enabled again. Finally, minimal, operation-level access rules are applied and validated.

In practice, this phased methodology ensures early functionality. Furthermore, it provides a clear path to scalable authorization. Therefore, security becomes an enhancement rather than a blocker. Most importantly, this approach reflects the “Secure After MVP” principle built into PromptXL.

How PromptXL’s RLS Workflow Is Structured

PromptXL follows a clear two-phase development blueprint:

Phase One — Function First

  • RLS disabled on all tables
  • AI-generated CRUD works instantly
  • UI iterates without permission errors
  • Database queries return real rows immediately

Phase Two — Add Security

  • Ownership columns added (user_id, organization_id, created_by)
  • RLS re-enabled per table
  • Rule-based policies defined for each CRUD operation
  • Multi-tenant isolation tested
  • Keys reviewed for risk exposure

This structure enables predictable debugging and reliable policy enforcement.

Why Disabling RLS Early Accelerates MVP Delivery

At the MVP design stage, AI builders generate queries like this:

insert into tasks(title) values('Test task');
select * from tasks;

With RLS ON by default, Supabase denies this unless a policy exists. In the promptxl rls workflow, however, RLS is OFF intentionally during early development, allowing queries to run without mandatory checks and enforcing ownership only later.

You regain control of the development flow, avoid cryptic policy denials, and stay focused on feature delivery rather than permission configuration.

Schema Is the Pre-Step to Any Reliable RLS Policy

Before enabling policies again, PromptXL ensures identity scaffolding exists.

Example schema addition:

alter table tasks
add column created_by uuid references auth.users(id);

For multi-tenant apps:

alter table tasks
add column organization_id uuid not null;

These columns provide RLS conditions something to evaluate later.

Re-Enabling Supabase RLS After Your MVP Is Ready

Then apply this per table:

ALTER TABLE tasks ENABLE ROW LEVEL SECURITY;

Your app will lock at this point—that’s expected. Now restore access with minimal, functional policies.

CRUD Policy Patterns PromptXL Uses to Restore Access

1. SELECT

create policy "Tenant row read"
on tasks
for select
using (created_by = auth.uid());

2. INSERT

create policy "Tenant row insert"
on tasks
for insert
with check (created_by = auth.uid());

These starter rules are simple, predictable, and scale later.

How PromptXL Ensures Security Without Losing Build Velocity

The value of promptxl rls workflow is that it makes RLS predictable by doing the steps in the correct sequence:

  1. Build MVP with RLS disabled
  2. Add ownership columns
  3. Re-enable RLS gradually after MVP works
  4. Create action-specific policies
  5. Test tenant isolation and role overrides
  6. Harden logic in the backend only
  7. Validate keys are not exposed to the client

This prevents 90% of permission-related build failures.

Common Mistakes promptxl rls workflow Prevents

MistakeAvoided by PromptXL?
RLS enabled before schema is ready✅ prevented
AI inserts failing due to no INSERT policy✅ prevented
Using service_role in frontend✅ blocked by workflow
Only SELECT policy exists, others missing✅ prevented
Tenant leakage not tested✅ tenant tests encouraged

Summary — The Fastest Path to a Working and Secure App

The promptxl rls workflow makes security predictable without competing with early MVP design. It prioritizes usability in development, then layers authorization only after tenants and owners are defined. This reflects the exact Secure-Later philosophy PromptXL was built on.
