Laravel Migration Scaffold Skill

Use this skill when creating database table definitions.

Rules

1. Anonymous Classes

• Always use return new class extends Migration.

2. Foreign Keys

• Standard: Use foreignIdFor() constrained to the model class. $table->foreignIdFor(\App\Models\User::class)->constrained()->cascadeOnDelete();
• Nullable: usage of ->nullable() comes before constrained().

3. ID and UUIDs

• Check if the project or related models use UUIDs.
• If UUID: $table->uuid('id')->primary();
• If ID: $table->id();

4. Indexing

• Add indexes to columns that will be frequently searched or used in WHERE clauses (e.g., slug, email, status).

Workflow

1. Ask: "Does this table relate to existing models?"
2. If yes, check the parent model's ID type (int or uuid) to ensure the foreign key matches.
3. Write the migration file.
