Introduction & AI Signs
An open-source guardrail framework engineered to identify and eliminate telltale AI mistakes, generic purple gradients, and vibe-coded cliches.
msitte / laucn is designed to correct the systematic imperfections that AI models inject into codebases. When coding models generate frontends without explicit guardrails, they fall into predictable habits that immediately look synthetic.
In accordance with Skills.md, whenever you invoke the initiation command, the coding agent reads the instruction set, confirms with installed successfully (1.0.1 beta), lists available commands, and immediately activates the webh.md negative constraints.

The AI Signs
AI models leave unmistakable fingerprints when building websites. Based on the negative constraints defined in webh.md, here is the breakdown of what AI models usually do in the reverse:
1. Purple-to-Indigo & Neon Gradients
AI models almost universally pick #0b1020 backgrounds drowned in purple-blue-indigo linear gradients, glowing circular blurs, and gradient-masked headline text to fake a "futuristic" aesthetic.
#111112, #161619), deliberate monochrome contrast, and subtle 1px border lighting.
2. Unicode & Emojis As Fake Icons
Instead of linking real graphical icons, AI models routinely insert emojis (✨, 💡, 🚀) or text symbols (●, ✕, ✓, and em-dashes —) directly into headlines, cards, and buttons. They often attempt to construct logos from Unicode glyphs.
3. Ghost UI & Missing Placeholders
AI models either generate completely text-only interfaces without images, or invent hallucinated Unsplash links that 404. They also generate fake "Upload Image" buttons inside mockups instead of coding real image tags.
<img> placeholders for the site owner to fill in code.
4. Saturated Electric Accent Abuse
AI models plaster hyper-saturated neon lime (#22c55e), electric cyan (#06b6d4), and hot magenta on button borders and card outlines, creating eye strain.
#00f59b), calibrated off-whites, and secondary grays.
5. Illegible, Ultra-Thin Typography
AI models output ultra-thin font weights (100–300), excessive letter-spacing, and washed-out gray text that fails accessibility and contrast tests.
6. Non-Functional Mockup Traps
AI models create UI cards, tabs, and copy buttons with zero interactive states, no active indicator lines, and non-functional clipboard logic.
Core webh.md Rules Summary
# WEBSITE DESIGN GUIDELINES (webh.md)
- Never use Unicode symbols, decorative symbols (●, ✨), or em-dashes as icons.
- Avoid purple-blue-indigo gradients and electric neon accents (#22c55e, #06b6d4).
- Use empty HTML <img> placeholders for future assets; never hallucinate stock images.
- Enforce solid dark surfaces (#111112, #161619) over gradient backgrounds (#0b1020).
- Ensure all components support genuine interactive states and keyboard navigation.
