I built a CLI that detects patterns AI coding tools leave behind: empty catch blocks, hardcoded secrets, as any everywhere, comments that restate the code, god functions, SQL concatenation.24 rules across JS/TS and Python. Zero config, runs offline, regex-based so it's fast. npx @yuvrajangadsingh/vibecheck . Also ships as a GitHub Action for inline PR annotations and standalone binaries (no Node required).Why: CodeRabbit found AI-generated PRs have 1.7x more issues than human PRs. Veracode says 45% of AI code samples have security vulnerabilities. "Vibe coding" is everywhere now but nobody's linting for the patterns it produces.This isn't a replacement for ESLint. It catches things ESLint doesn't look for, like catch blocks that only console.error without rethrowing, bare except: pass in Python, or mutable default arguments.

Discussion

4 comments analyzed.

Competitors mentioned: Caliper, traditional linters

Concerns raised: regex approach too brittle for edge cases and general use, misses logic bugs and spec drift that pass syntax checks, won't catch all anti-patterns, only surface-level issues

Feature requests: integration hook for vibecoding/AI generation sessions, AI layer to evaluate against project-specific coding conventions, deeper analysis beyond deterministic pattern matching
