Claude Code Skills - Jeremy Dawes

Overview

A comprehensive collection of production-ready skills for Claude Code CLI. Each skill encapsulates best practices, prevents common errors, and dramatically reduces token usage during development.

Skills

The Problem

When using Claude Code for development, you often encounter:

Repeated context - Explaining the same patterns every session
Common errors - Same mistakes with Tailwind v4, Cloudflare bindings, etc.
Token waste - Re-teaching Claude things it should already know
Inconsistent outputs - Different approaches each time

Developers needed a way to encode proven patterns and have Claude apply them automatically.

Feature	Manual	With Skills
Token Usage(~50% less)	12-15k	4-6k
Common Errors(prevented)	2-4	0
Setup Time	2-4 hours	15-45 min
Pattern Consistency
Auto-Discovery

Solution

Built a skill system that Claude Code automatically discovers and applies:

How It Works

Claude Code scans ~/.claude/skills/ on startup and suggests relevant skills during conversation. No configuration needed - just install and go.

Key Features

Auto-discovery - Claude finds and suggests skills contextually
Plugin marketplace - One-command installation
Token efficiency - Pre-loaded context means less explanation
Error prevention - Known issues caught before they happen
Consistent patterns - Same quality output every time
