## What This Skill Does
Multi-phase database backup workflow with validation...

## When It Activates
- "I need to backup my database"
- "How do I restore from backup?"
- "Set up automated backups"

How It Works in Practice:

1. You install a plugin:

   /plugin install postgres-backup-pro@claude-code-plugins-plus
   

2. You mention your need naturally:

   "I need to backup my production PostgreSQL database before the migration"

3. Claude automatically:

   • Detects the backup skill is relevant
   • Activates Database Backup Automator skill
   • Guides you through: connection → backup → verification → storage
   • No slash commands needed!

4. You get expert help:

   • Multi-phase workflows (analysis → execution → validation)
   • Code examples and error handling
   • Best practices built-in
   • Context-aware recommendations

Key Difference from Commands:

• Commands: You type /backup-database explicitly
• Skills: Claude recognizes "I need to backup" and helps automatically
• Result: More natural, conversational development workflow
