## 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:
-
You install a plugin:
/plugin install postgres-backup-pro@claude-code-plugins-plus
-
You mention your need naturally:
"I need to backup my production PostgreSQL database before the migration"
-
Claude automatically:
- Detects the backup skill is relevant
- Activates
Database Backup Automator skill
- Guides you through: connection → backup → verification → storage
- No slash commands needed!
-
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
