Inspect Authorization Responses and Policy Denial Reasons with Gate::inspect()

Use Gate::inspect() to retrieve detailed Response objects explaining why an authorization check was permitted or denied.

Standard Gate::allows() and Gate::denies() return a simple boolean. When a policy check fails, you often need to display the exact explanation (such as "Your trial expired" vs "Insufficient permissions") to the user.

Gate::inspect() returns a full Illuminate\Auth\Access\Response object.

Returning Custom Error Messages in Policies

namespace App\Policies;

use App\Models\Project;
use App\Models\User;
use Illuminate\Auth\Access\Response;

class ProjectPolicy
{
    public function update(User $user, Project $project): Response
    {
        if ($project->is_archived) {
            return Response::deny('This project is archived and cannot be modified.');
        }

        if ($user->id !== $project->owner_id) {
            return Response::deny('You do not own this project.');
        }

        return Response::allow();
    }
}

Inspecting the Response

use Illuminate\Support\Facades\Gate;

$response = Gate::inspect('update', $project);

if ($response->allowed()) {
    // Authorized to proceed
} else {
    // Retrieve custom denial message
    echo $response->message();
    // e.g. "This project is archived and cannot be modified."
}

Summary

Returns an Illuminate\Auth\Access\Response instance with ->allowed(), ->denied(), and ->message().
Allows policy methods to communicate specific failure reasons to users and API responses.
Eliminates guesswork when debugging authorization denials.
