A practical guide to implementing Anthropic's five multi-agent workflow patterns using the Laravel AI SDK. Covers prompt chaining (assembly-line pipelines), routing (classify then delegate), parallelization (concurrent agents via Concurrency::run()), orchestrator-workers (dynamic planning with tool-calling sub-agents), and evaluator-optimizer (generate-evaluate-refine loops). Each pattern includes working PHP code examples using the agent() helper, structured output via schema:, and Laravel's Pipeline. The SDK is installable via composer require laravel/ai.
