Vercel-Supabase Environment Alignment Check

Vercel deployments connect to the wrong Supabase database when environment variables like SUPABASE_URL are misconfigured. This Skill validates Vercel environment variable configurations against Supabase project references to detect and report discrepancies in database connections between preview and production environments.

To check environment variable alignment, run the Vercel-Supabase alignment check for your project. It automatically verifies if Vercel environment variables correctly point to the intended Supabase project for staging and production, generating a clear diagnostic report detailing any detected misalignments.

Preventing staging deployments from using the production Supabase database requires verifying branch-to-environment mappings. This Skill provides automated diagnostics and specific remediation steps to fix incorrect Vercel branch mappings and misconfigured local Supabase links, ensuring data integrity.

Yes, you can use this check to troubleshoot data inconsistency errors after a Vercel deployment. If users report errors, this check quickly confirms if the deployment is accidentally using the production database instead of staging, guiding the fix with specific troubleshooting steps.
