170 production-ready skills for Claude Code CLI

Version 3.2.3 | Last Updated: 2026-04-08

**For all other Platforms like opencode, codex and others, you can use https://github.com/enulus/OpenPackage **

---

A curated collection of battle-tested skills for building modern web applications with Cloudflare, AI integrations, React, Tailwind, and more.

PS: if skills.sh warns about any skill: Their scan process is a outdated LLM which flags newest versions pins (like in ZOD) as non existent and by that potentially malicous.

How It Works

Auto-Discovery

Claude Code automatically checks ~/.claude/skills/ for relevant skills before planning tasks:

User: "Set up a Cloudflare Worker with D1 database"
           ↓
Claude: [Checks skills automatically]
           ↓
Claude: "Found cloudflare-d1 skills.
         These prevent 12 documented errors. Use them?"
           ↓
User: "Yes"
           ↓
Result: Production-ready setup, zero errors, ~65% token savings

Note: Due to token limits, not all skills may be visible at once. See ⚠️ Important: Token Limits below.

Skill Structure

Each skill includes:
