What's Wrong?

Description:

When creating Laravel migration files via artisan make:migration and then editing them using Claude Code's Edit tool, the migrations appear to run successfully
but don't actually apply the schema changes to the database.

Actual Behavior:

• Laravel marks migration as "migrated" in migrations table
• No errors are thrown
• Schema changes are not applied to database
• Manually creating identical file with same content works immediately

Environment:

• OS: Linux 6.12.21-1-lts
• Laravel 8 application
• Using Laravel Sail (Docker)
• MariaDB database

Additional Context:
This has occurred multiple times. The migration file content appears identical when read back, suggesting a possible file encoding, timing, or caching issue
during the Edit tool's write operation. The silent failure is particularly concerning as there's no indication anything went wrong.

What Should Happen?

Expected Behavior:
Migrations edited via Edit tool should execute properly and apply schema changes.

Steps to Reproduce

Steps to Reproduce:

1. Create a migration: ./vendor/bin/sail artisan make:migration add_field_to_table
2. Use Claude Code Edit tool to add schema changes (e.g., $table->json('field_name')->nullable()->after('other_field');)
3. Run migration: ./vendor/bin/sail artisan migrate
4. Migration shows as "Migrated" successfully
5. Check database schema - the column was not added
6. Manually create identical migration file in IDE and run it - works perfectly
