AI RULEBOOKSupabase & PostgreSQL Windsurf Cascade Rules
Production-grade architectural rulebook for Supabase & PostgreSQL. Engineered to eliminate LLM hallucinations, enforce strict deterministic conventions, and prevent architectural drift across Cursor IDE, Claude Code CLI, and autonomous multi-agent pipelines.
.windsurf/rules/supabase.mdFailure Patterns Prevented for Supabase & PostgreSQL
Supabase applications are prone to catastrophic security leaks if Row Level Security (RLS) is omitted or if client-side service_role keys are exposed. Cursor rules ensure RLS is enabled on every table and authentication is validated server-side.
- Invokes deprecated or removed APIs from older model training weights
- Generates conflicting configuration files and invalid imports
- Silently drops type-safety, boundaries, or transaction isolation
How to Install Supabase & PostgreSQL Windsurf Cascade Rules via Terminal
Step 1: Open Project Directory & Verify Target Placement
Open your terminal and navigate to your project root folder where the .windsurf/rules/supabase.md file will reside. Ensure the file is placed at the exact path below relative to your project root so the AI engine automatically loads it:
Step 2: Fetch Rule File via Terminal Command
Run curl, PowerShell, or wget to stream the rule directly from the DevScratchpad raw API endpoint and write it to .windsurf/rules/supabase.md:
Terminal One-Liner Install
Run directly in your project root to stream and write this rule file with one command.
mkdir -p ".windsurf/rules" && curl -fsSL "https://www.devscratchpad.tech/api/raw/windsurf-rules/supabase" -o ".windsurf/rules/supabase.md"Step 3: Verify and Activate with AI Agent
Launch your AI coding assistant (Universal AI Assistants). The assistant will automatically discover .windsurf/rules/supabase.md in your repository and apply the architectural guardrails, type constraints, and verification protocols during code generation.

Technical FAQ: Supabase & PostgreSQL AI Rulebooks
Does this rule check for RLS?
Yes. It mandates that any table creation migration explicitly enables Row-Level Security.
