# premium-saas-web

> Open-source Agent Skill (SKILL.md) that teaches AI coding agents (Claude Code, OpenAI Codex, Cursor, Google Antigravity) to build premium SaaS, AI-product, agency and portfolio websites. It contains 4 design directions, 18 copy-ready CSS/HTML recipes and a GSAP + Lenis motion system measured from top-selling ThemeForest templates. MIT licensed. Made by MiddleSugar7000, a full-stack developer for hire.

Install for any agent: `npx skills add MiddleSugar7000/premium-saas-web-skill`

Benchmark (Claude Opus 5.5, 4 one-line prompts, isolated runs, no memory): 97.5% of automated design-quality checks passed with the skill vs 75% without. That costs about 11 min and $2.70 per page vs 2.3 min and $0.70.
