Show HN: Vibecheck – a pre-launch security audit for AI-built apps

Vibecheck is a zero-dependency scanner with 60+ checks plus AI-agent skills that audit AI-built apps for exposed secrets, missing Supabase RLS, auth gaps, and deploy misconfigurations, producing a 0–100 Launch Score with a GO/NO-GO verdict and copy-paste fix prompts. It includes an always-on guard hook that blocks agents from hardcoding API keys or committing .env files, and can run in CI via a single Node script with --fail-on critical. The audit is read-only, makes no network calls, and never runs the project's code.
