Apply Database Migration

Check for pending migrations and generate Lovable deployment prompts.

Instructions

1. List migration files:

   • Show all files in supabase/migrations/
   • Sort by timestamp (filename prefix)

2. Show migration content for review:

-- Migration: [filename]
[SQL content]

3. Warn about destructive operations:
   • Check for: DROP, DELETE, TRUNCATE, ALTER...DROP
   • If found:

⚠️ **Destructive operation detected!**
This migration contains: [operation]
Ensure you have a backup before proceeding.

4. Generate deployment prompt:

📋 **LOVABLE PROMPT:**
> "Apply pending Supabase migrations"

Or for review first:

📋 **LOVABLE PROMPT:**
> "Review and apply the migration [filename]"

5. Suggest verification:

After applying, verify:
> "Show me the [table_name] table structure"

6. Remind about CLAUDE.md:
   • If new tables created, update database tables section

Check for Yolo Mode

After generating the prompt, check if yolo mode is enabled:

1. Read CLAUDE.md:

   • Look for ## Yolo Mode Configuration (Beta) section
   • Check Status field
   • Extract Testing and Debug Mode settings

2. If Status: on:

   • ✅ Yolo mode is enabled
   • Activate yolo skill (see /skills/yolo/SKILL.md)
   • Execute browser automation workflow: a. Navigate to Lovable project b. Submit migration prompt c. Monitor for successful application d. Run tests if Testing: on e. Show deployment summary
   • Exit (don't show manual prompt)

3. If Status: off or not found:

   • ⏸️ Yolo mode is disabled
   • Show manual prompt (as shown in examples below)
   • Suggest enabling yolo mode:
