๐จ SKILL.md Skills for Claude Code, Cursor, Codex CLI & Every AI Coding Assistant
A curated collection of open-spec SKILL.md skills โ install once, work across every major AI coding tool

โญ Star this repo โ it helps other developers discover faithful, evidence-driven AI skills instead of fancy autocomplete.
What's in here
A personal collection of SKILL.md-standard agent skills for AI coding assistants โ Claude Code, Cursor, OpenAI Codex CLI, ChatGPT, GitHub Copilot, Aider, and any other tool that supports the open SKILL.md specification.
Each skill lives in its own folder under skills/ with two files:
SKILL.md โ the agent-facing spec (frontmatter + instructions the AI reads)
README.md โ the human-facing detail page (what it does, how to install, examples)
๐ Available skills
| Skill | What it does | Detail |
|---|
clone-ui | Pixel-faithful website & UI cloning from URL, screenshot, or Figma frame โ anti-hallucination 7-phase flow with adversarial sub-agent verification, computed-style parity checks, and per-target lessons log. Outputs production-ready code in your stack (React, Vue, Next.js, Astro, Svelte, plain HTML). | README ยท SKILL.md |
More skills are on the way. Each one ships independently โ install just the ones you need.
๐ฆ Install โ one command per skill
Skills are installed individually using the skills.sh CLI:
npx skills add santowilem/skills --skill <skill-name>
For example, to install clone-ui:
npx skills add santowilem/skills --skill clone-ui
After installation, restart your AI assistant. The skill triggers automatically based on natural-language prompts โ no slash commands required. See each skill's README for trigger phrases and examples.
๐ Compatibility โ works across every major AI coding assistant
All skills in this repo follow the SKILL.md open specification โ released by Anthropic in 2025 and adopted by OpenAI for Codex CLI and ChatGPT. One skill file works everywhere:
