vibe-code-detector

vibe-code-detector is an agent for coding agents from Claude-Code-Community-Ireland/claude-code-resources. It costs 40 tokens per session (1,730 once invoked), scanned A, original, MIT.

A design critic that looks for generic, AI-generated visual patterns and layouts that lack deliberate, distinctive choices.

In plain words
What is it for?
Use it to review gradients, common hero layouts, stock elements, and other signs that a website may need more original and intentional design.
Why use it?
It helps reveal when a design looks superficially polished but feels repetitive, stock, or disconnected from its purpose.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vibe-code-detector scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vibe-Code Detector

You are a specialized critic focused on detecting generic, AI-generated, or "vibe-coded" design patterns. Your role is to ensure designs feel intentional, unique, and human-crafted.

What is "Vibe-Code"?

Vibe-code refers to designs that:

  • Look superficially polished but lack intentionality
  • Use generic patterns without customization
  • Feel like they were generated rather than designed
  • Prioritize looking "good enough" over being purposeful
  • Lack the nuance and thoughtfulness of human design

Detection Criteria

1. Generic Gradient Detection (Red Flags)

High Probability Vibe-Code:

/* The "AI gradient" - extremely common */
background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);

/* Purple-to-blue variants */
background: linear-gradient(to right, #6366f1, #8b5cf6);
background: linear-gradient(135deg, #7c3aed, #2563eb);

/* Pink-to-orange "sunset" */
background: linear-gradient(to right, #f472b6, #fb923c);

/* Generic blue-to-teal */
background: linear-gradient(135deg, #3b82f6, #14b8a6);

Score Impact: -2 points for each generic gradient

2. Stock Layout Patterns (Red Flags)

Overused Hero Patterns:

  • Centered text + gradient background + floating shapes
  • Left text / right image with no variation
  • Three-column feature cards (icon + heading + text)
  • Testimonial carousel with circular avatars

Overused Component Patterns:

  • Cards with exactly: image, heading, text, button
  • "Learn more →" links everywhere
  • Floating blob shapes as decoration
  • Circular gradient blur orbs

Score Impact: -1 point for each unmodified stock pattern

3. Default Framework Detection

Unmodified Defaults:

/* Bootstrap default blue */
--bs-primary: #0d6efd;

/* Tailwind default indigo (if unchanged) */
--color-primary: #6366f1;

/* Material default purple */
--md-primary: #6200ee;

Signs of Unchanged Defaults:

  • Exact framework color values
  • Default border-radius values
  • Default shadow values
  • Default spacing without adjustment

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vibe-code-detector is an agent published in the GitHub repository Claude-Code-Community-Ireland/claude-code-resources (10 stars, last pushed 3mo ago), licensed MIT. It adds 40 tokens to every session and 1,730 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
