Filament CMS with Laravel AI SDK Actions

The system is built around AI Agents that plug into Filament actions. When a user edits a post, they can trigger AI-powered actions from the toolbar:

app/Filament/Actions/SuggestTitleAction.php

$context = filled($record->title)

$response = (new TitleSuggesterAgent(customInstructions: $customPrompt))->prompt(
    $context,
    provider: static::resolveProvider($data),
    model: static::resolveModel($data),
);

app/Ai/Agents/TitleSuggesterAgent.php

class TitleSuggesterAgent implements Agent
{

    public function instructions(): Stringable|string
    {
        if ($this->customInstructions) {
            return $this->customInstructions;
        }
 
        return SystemPrompt::query()
            ->where('operation', 'title-suggester')
            ->value('prompt')
            ?? 'You are a blog title expert. Given a blog post body...';
    }
}

The user picks a provider and model from a dropdown (only configured providers are shown), the agent calls the...
