ViberTest doesn't fix your code — it shows you exactly what needs fixing and why.

24 rules. Every AI code smell.

Each rule targets a specific pattern that AI-assisted development commonly produces. From security to accessibility to ship-readiness.

Security Anti-Patternscritical

SQL injection, eval(), hardcoded secrets, CORS wildcards, localStorage tokens.

Dead Codemedium

Unused exports, unreachable branches, and commented-out blocks.

Missing Testscritical

No tests, low coverage, empty tests, trivial assertions, skipped tests.

Accessibilitymedium

Missing alt text, non-semantic click handlers, inputs without labels.

Generic titles, missing meta tags, default favicon, no 404 page.

Project Standardsmedium

Missing tsconfig, linter, .gitignore, .env.example, README.

Console Pollutionlow

Leftover console.log statements that don't belong in production.
