A Laravel database migration generator for a CatchAdmin module. A migration is a versioned PHP file that creates or removes a database table and its fields.

Use it when creating the database table for a module. It maps field types such as strings, text, and integers to Laravel schema code and includes a rollback operation.

It reduces manual table-definition work and includes CatchAdmin's standard fields and indexes in the generated structure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00011	$0.00449
Opus 5.5	$0.00004	$0.00180
Sonnet 5.5	$0.00002	$0.00090
Haiku 4.5	$0.00001	$0.00045

Security

Grade A, and why

migration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Template

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up(): void
    {
        Schema::create('{table}', function (Blueprint $table) {
            $table->id();
            
            // Business fields (generated from definition)
            
            // CatchAdmin standard fields
            $table->unsignedInteger('creator_id')->default(0);
            $table->unsignedInteger('created_at')->default(0);
            $table->unsignedInteger('updated_at')->default(0);
            $table->unsignedInteger('deleted_at')->default(0);
            
            // Indexes
            $table->index(['status', 'deleted_at']);
        });
    }

    public function down(): void
    {
        Schema::dropIfExists('{table}');
    }
};

Field Type Mapping

Type	Migration Code
string(n)	`$table->string('name', n)`
text	`$table->text('description')->nullable()`
integer	`$table->unsignedInteger('count')->default(0)`
decimal(m,n)	`$table->decimal('price', m, n)`
tinyint	`$table->tinyInteger('status')->default(1)`
foreign_key	`$table->unsignedBigInteger('category_id')->default(0)->index()`
date	`$table->date('birth_date')->nullable()`
datetime	`$table->dateTime('published_at')->nullable()`
json	`$table->json('options')->nullable()`

Important

CatchAdmin 使用 unsigned integer 作为时间戳，不使用 Laravel 默认的 timestamps()
软删除使用 deleted_at unsigned integer，不使用 softDeletes()
外键字段需要添加 index()
