# AE.LTD Skill Builder

## What This Skill Does

Production-ready skill factory for Claude Code. Creates skills that Claude can autonomously discover and use across all surfaces (Claude.ai, Claude Code, SDK, API).

1. Scaffold new skills with proper structure
2. Validate and fix existing skills
3. Generate templates (basic, intermediate, advanced)
4. Automate lifecycle with hooks

## Prerequisites

- Claude Code 2.0+ or Claude.ai with Skills support
- Basic understanding of Markdown and YAML
- Text editor or IDE

## Quick Start

```bash
# Interactive skill creation
./scripts/create-skill.sh my-new-skill

# Validate all skills
./scripts/validate-skill.sh

# Auto-fix naming issues
./scripts/fix-skill.sh
```
