Laravel 13 PHP Attributes

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Scan existing models/jobs/controllers for legacy protected $fillable / $hidden / $connection properties to convert
2. fuse-ai-pilot:research-expert - Verify Laravel 13 release notes for attribute coverage and edge cases
3. mcp__context7__query-docs - Pull authoritative examples from laravel.com/docs/13.x

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

Critical Rules

1. NEVER mix attributes and legacy properties - #[Fillable(['name'])] + protected $fillable = [...] causes Laravel to ignore the attribute silently
2. Class-level only - All Eloquent / Job / Controller attributes apply to the class, never to private/protected methods
3. Single source of truth - Choose attributes OR properties per class; refactor in one pass to avoid drift
4. Inheritance is additive - Child class attributes merge with parent attributes; redeclare to override
5. Import the right namespace - Illuminate\Database\Eloquent\Attributes\* for Eloquent, Illuminate\Queue\Attributes\* for Jobs

Quick Reference

Eloquent model

use Illuminate\Database\Eloquent\Attributes\{Table, Fillable, Hidden, Appends};

#[Table('flights')]
#[Fillable(['name', 'origin'])]
#[Hidden(['password'])]
#[Appends(['is_admin'])]
class Flight extends Model {}

Queue job

use Illuminate\Queue\Attributes\{Connection, Queue, Tries, Backoff};

#[Connection('redis')]
#[Queue('podcasts')]
#[Tries(5)]
#[Backoff([10, 30, 60])]
class ProcessPodcast implements ShouldQueue {}

Best Practices

DO

• Convert one class at a time and run tests between commits
• Keep attribute imports grouped at the top via PHP 8.1 grouped use syntax
• Use #[Fillable] for mass-assigned models and #[Unguarded] only on trusted internal models
• Combine #[Connection] + #[Queue] on Jobs to centralize routing intent

DON'T

• Don't mix #[Fillable(['x'])] with protected $fillable = ['y'] - the property silently wins on some setups, the attribute on others
• Don't place Eloquent/Job attributes on methods - they target the class only
• Don't put #[Authorize] on a controller without an underlying Policy registered in AuthServiceProvider
• Don't forget to drop the legacy $tries, $backoff, $timeout properties after adding the attributes - duplication is a red flag for code review
