Why AI Code Needs a Guardian: Lessons from the ARC-AGI-2 Benchmark

The gap between human and AI reasoning is real—and it's showing up in your codebase. Learn how the ARC-AGI-2 benchmark reveals fundamental AI limitations and why CodeSlick acts as a guardian for AI-generated code.

The ARC-AGI-2 Reality Check

The ARC-AGI-2 leaderboard remains one of the most honest benchmarks for progress toward AGI. As of early 2026, top frontier models (GPT-5.2 Pro, Poetiq, Gemini variants) are scoring around 54% on these novel visual reasoning puzzles—tasks that require genuine abstraction, quick adaptation, and efficient problem-solving on problems never seen before.

Humans? Still near 100% at low cost (~$17/task equivalent).

This gap is a stark reminder: Today's AI crushes pattern-matching and data-rich tasks, but it still lacks the flexible, low-cost reasoning humans use on entirely new challenges. Scaling LLMs alone isn't closing it fast enough.

The Same Problem Exists in Code Generation

AI coding assistants (Copilot, Cursor, Claude, GPT-4) write code fast—but they frequently:

Hallucinate non-existent methods
Like .append() on strings or flawed logic patterns
Introduce security vulnerabilities
SQL injection, XSS, exposed secrets in committed code
Leave LLM fingerprints
Verbose docstrings, custom error classes, "TODO" comments that reveal AI authorship
Miss edge cases and logic flaws
Runtime errors that expose stack traces and internal paths

These aren't just annoyances—they're production risks. From runtime crashes exposing stack traces to critical security breaches, AI-generated code needs verification before it ships.

Introducing CodeSlick: The Security Guardian for AI-Generated Code

CodeSlick is the first security platform built specifically to protect against threats in AI-generated code. It combines industry-first AI detection with comprehensive security scanning to catch vulnerabilities before they reach production.

What Makes CodeSlick Different

Industry-First AI Code Detection

  • 150+ AI-specific signals (hallucination patterns, code smells, LLM fingerprints)
  • Detects code generated by GPT-4, Copilot, Claude, Cursor, and other AI tools
  • Catches hallucinated methods, suspicious patterns, and AI-specific vulnerabilities

Comprehensive Security Scanner

  • 294 total security checks across JavaScript, TypeScript, Python, Java, and Go
  • 95% OWASP Top 10:2025 coverage (100% for OWASP 2021)
  • Dependency vulnerabilities via Google OSV database
  • API security issues, hardcoded secrets, malicious packages

Blazing-Fast Integrations

  • GitHub App: Auto-scans PRs in <3 seconds with inline comments + SARIF support
  • CLI (npm): Pre-commit hooks for local development and CI/CD pipelines
  • Web Tool: No-signup browser-based scanner for instant code checks

AI-Powered Fixes

Intelligent fix generation using Claude 3.5 Sonnet (or your own OpenAI-compatible API key), with context-aware corrections

Free Tier Available

CodeSlick offers a free tier for individuals (20 PR analyses + 30 AI fixes per month, no credit card required), with paid plans for teams and enterprises that need unlimited scans, advanced features, and priority support.
