System Documentation

What problem does it solve?

This Skill prevents critical security breaches by detecting if the highly sensitive Supabase service_role key is accidentally exposed in client-side code, which bypasses all security policies.

Core Features & Use Cases

  • Critical Security Audit: Identifies the presence of the service_role key in client-side JavaScript bundles, inline scripts, or source maps.
  • Detailed Impact Analysis: Explains the severe consequences of exposure, including full database access, RLS bypass, and user impersonation.
  • Use Case: During a routine security audit of a web application using Supabase, this skill is run to ensure the service_role key is not present in any publicly accessible client-side code, preventing a P0 severity vulnerability.
