A curated collection of open-spec SKILL.md skills — install once, work across every major AI coding tool
⭐ Star this repo — it helps other developers discover faithful, evidence-driven AI skills instead of fancy autocomplete.
A personal collection of SKILL.md-standard agent skills for AI coding assistants — 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— the agent-facing spec (frontmatter + instructions the AI reads)README.md— the human-facing detail page (what it does, how to install, examples)
| Skill | What it does | Detail |
|---|---|---|
clone-ui |
Pixel-faithful website & UI cloning from URL, screenshot, or Figma frame — 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 · SKILL.md |
More skills are on the way. Each one ships independently — install just the ones you need.
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-uiAfter installation, restart your AI assistant. The skill triggers automatically based on natural-language prompts — no slash commands required. See each skill's README for trigger phrases and examples.
All skills in this repo follow the SKILL.md open specification — released by Anthropic in 2025 and adopted by OpenAI for Codex CLI and ChatGPT. One skill file works everywhere:
| Platform | Status | Install path |
|---|---|---|
| Claude Code | ✅ Native | ~/.claude/skills/ |
| Cursor | ✅ Native | ~/.cursor/skills/ |
| OpenAI Codex CLI | ✅ Native | ~/.codex/skills/ |
| ChatGPT | ✅ via Skills API | Upload SKILL.md as a project skill |
| GitHub Copilot Workspace | ✅ via registry | Reference the repo URL |
| Aider, Continue, others | Pipe SKILL.md verbatim into context |
See CONTRIBUTING.md for instructions on adding a new skill to this repo. Pull requests welcome — especially for skills that cover under-served workflows (component extraction, design-system ingestion, accessibility audits, visual regression, etc.).
