Claude Code Plugin | Agent Skills | Zero Dependencies | MIT
Your AI wrote the app; vibecheck makes sure it doesn't leak your users' data, or your wallet. One command gives a 0–100 Launch Score and a GO / NO-GO verdict, with plain-language findings and copy-paste fix prompts. Catches leaked API keys, missing Supabase RLS, open Firebase rules, routes without auth and billing abuse.
/vibecheck:fixfixes findings one at a time with a test, and/vibecheck:deploycatches "works locally, broken in production" before you ship.
