Vizra ADK Workflows

Vizra ADK Workflow Patterns

Workflows orchestrate multiple agents to accomplish complex tasks. Vizra ADK supports sequential, parallel, conditional, and loop workflows.

Workflow Types

Workflow	Use Case
Sequential	Steps that must execute in order
Parallel	Independent tasks that can run simultaneously
Conditional	Branching based on conditions or results
Loop	Iterating over data or repeating until condition met

Sequential Workflow

Execute agents in order, passing results between steps:

use Vizra\VizraADK\Workflows\SequentialWorkflow;

$workflow = SequentialWorkflow::create()
    ->addStep('research', ResearchAgent::class)
    ->addStep('analyze', AnalysisAgent::class)
    ->addStep('report', ReportGeneratorAgent::class);

$result = $workflow->run([
    'topic' => 'Market trends in AI',
    'depth' => 'comprehensive'
]);

Passing Data Between Steps

$workflow = SequentialWorkflow::create()
    ->addStep('fetch', DataFetcherAgent::class)
    ->addStep('transform', function ($previousResult, $context) {
        // Transform data from previous step
        return TransformAgent::run($previousResult['data'])
            ->withParameters(['format' => 'json'])
            ->go();
    })
    ->addStep('store', DataStorageAgent::class);

Parallel Workflow

Run multiple agents simultaneously for independent tasks:

use Vizra\VizraADK\Workflows\ParallelWorkflow;

$workflow = ParallelWorkflow::create()
    ->addTask('sentiment', SentimentAnalysisAgent::class)
    ->addTask('keywords', KeywordExtractionAgent::class)
    ->addTask('summary', SummarizationAgent::class);

$results = $workflow->run([
    'text' => $documentText
]);

// Results contain output from all agents
// $results['sentiment'], $results['keywords'], $results['summary']

With Timeout

$workflow = ParallelWorkflow::create()
    ->addTask('fast', FastAgent::class)
    ->addTask('slow', SlowAgent::class)
    ->timeout(30); // 30 second timeout

$results = $workflow->run($input);
