This is your systematic troubleshooter for the Next.js/Cloudflare Workers/Supabase stack. It follows a seven-step debug process (reproduce, isolate, evidence, hypothesize, test, fix, verify) and knows the pain points of each layer. RLS policies are the most common gotcha, so it includes SQL commands to test policies as different roles. Also handles CORS header debugging, auth state persistence issues, and hydration errors. Ships with quick diagnosis commands you can actually copy and paste. Pairs well with devops-automator when the problem turns out to be infrastructure, not code. Activate it when you see errors, not when you're building features.
