Example workflows you'd like to see?

[rmcdaniel]

Hey there! 👋 I'm the creator of Laravel Workflow, and I'm working on a blog post that dives into using Laravel Prism + Workflows together.

If you're building anything with Prism or considering it, are there any particular workflows you'd love to see modeled or broken down? Think auth flows, document parsing, moderation queues, agent coordination or anything else you're struggling with or just curious about.

Drop your ideas or use cases here and I'll try to cover them in the post (with code!).

One workflow I’d love to see is something like an automated exception/log monitor — a flow that watches for exceptions or log patterns and then suggests potential solutions inline or in context. Ideally, it wouldn’t just flag the issue, but also surface a well-thought-out recommendation or next action based on the exception type or stack trace. Using Prism + tools, this can be done.

Here is a rough first pass.

// config/logging.php

'stack' => [
    'driver' => 'stack',
    'channels' => explode(',', env('LOG_STACK', 'single')),
    'ignore_exceptions' => false,
    'tap' => [App\Logging\LogTap::class],
],

// app/Logging/LogTap.php

namespace App\Logging;

use App\Workflows\Prism\PrismWorkflow;
use Illuminate\Log\Logger;
use Workflow\WorkflowStub;

class LogTap
{
    public function __invoke(Logger $logger): void
    {
        $logger->pushProcessor(function ($record) {
            if ($record['level_name'] !== 'ERROR') {
                return $record;
            }
            $workflow = WorkflowStub::make(PrismWorkflow::class);
            $workflow->start($record);
            return $record;
        });
    }
}

// app/Workflows/Prism/PrismWorkflow.php

namespace App\Workflows\Prism;

use Workflow\ActivityStub;
use Workflow\Workflow;

class PrismWorkflow extends Workflow
{
    public function execute($record)
    {
        $result = yield ActivityStub::make(PrismActivity::class, $record['context']['exception']);

        return $result;
    }
}

// app/Workflows/Prism/PrismActivity.php

namespace App\Workflows\Prism;

use Prism\Prism\Prism;
use Prism\Prism\Enums\Provider;
use Workflow\Activity;

class PrismActivity extends Activity
{
    public function execute($exception)
    {   
        $error = $exception->getMessage();
        $stack = $exception->getTraceAsString();
        $prompt = "Figure out the cause of this error and stack trace: {$error} {$stack}";
        $response = Prism::text()
            ->using(Provider::OpenAI, 'gpt-4')
            ->withPrompt($prompt)
            ->asText();

        return $response->text;
    }
}

Then I triggered an error with this code:

public function handle()
{
    $a = 2 / 0;
}

$ php artisan tinker
> \Workflow\WorkflowStub::load(45)->output()
= """
  The error is a 'Division by zero' error which is occurring in your `App\Console\Commands\Workflow` class<E2><80><99>s `handle()` method. This kind of error occurs when a number is attempted to be divided by zero, which is mathematically undefined behavior. So you have to correct your code to avoid such cases. Check any mathematical operations (specifically division) you are performing in the `handle()` method. \n
  \n
  Make sure the divisor is not zero before performing the division. You could add an additional check before the division operation, something like this:\n
  \n
  ```php\n
  if ($divisor != 0) {\n
      $result = $dividend / $divisor;\n
  } else {\n
      // throw an exception or handle the error in some way\n
  }\n
  ```\n
  \n
  This way you're ensuring that you're not dividing by zero, which would cause the error.
  """

Please let me know how I could make this example more interesting/useful to your real-world scenario. Thanks!

That's already useful, thanks for that.
One note though, in case of specific errors that LLM's are not trained yet, tools could come in handy. Tool, that searches google for you and feeds the result back to LLM and gives you freshly updated (updated documentation based) results. That could be even more accurate in predicting correct solutions.

Did you ever write that blog post though? Couldn't find it and would love to see how you would mix Laravel Workflow with PrismPHP

[rmcdaniel]

Not yet. The PrismActivity I posted above gives a general feel for how you would use it. If there are any specific workflows you'd like to see please let me know. Thanks!

First of all, thank you very much for creating Laravel Workflow. I've been playing around with it for about a month and we're using Prism and Workflow very closely together (so far mostly for data crawling: ScrapeUsingFirecrawl → StructureDataFromMarkdownFile → SaveSnapshot → GenerateAndSaveEmbedding) and it's working quite well so far.

The next exploration I would like to do with both Prism and Workflow is to start building AI agents in a reusable way; I am particularly interested in breaking down the agent workflows described by Anthropic in their now famous blog post.

I will also certainly explore "deep search" in database data.

Cheers!

I have posted the first blog post here: https://medium.com/@rlmc/building-reliable-agentic-loops-with-laravel-workflow-and-prismphp-85f5738f71f6

I really wanted to illustrate what I think makes Laravel Workflow valuable to Prism users. This workflow will ask an LLM to produce structured output and validate it against business logic. If the generated output fails validation, the workflow will automatically reprompt the LLM until it generates valid output. You can also try out Laravel Workflow and Prism in a GitHub codespace where everything has already been setup for you.

Thanks for the publication, really interesting to read.

I'm also using your package and have migrated from Temporal because it's simpler, and using a standard queue in my workflow is much faster. Thanks you for your work!
