Orchestrator-Worker Pattern
Orchestrator-Worker Pattern
Coordinate multiple worker agents for project management. Handles task distribution, progress tracking, and result synthesis.
Use this when an orchestrator agent built with Experimental_Agent must assign tasks to typed worker tools and report progress as it streams.

Problems solved
Technical challenges this implementation handles out of the box.
- Coordinate specialized worker tools from an orchestrator agent
- Assign tasks across disciplines through strongly typed tools
- Track deliverables and progress in a streaming agent UI
- Demonstrate the orchestrator-worker pattern with Experimental_Agent

Setup
Requirements, wiring steps, and what this pattern adds to your project.
Getting started
Pick how you want to pull this pattern in. Then wire env vars and routes the same way.
- 1
Download → Next.js app
Use Download → Next.js app in the preview toolbar. You get a zip scaffold (Pro downloads rewrite preview `/view/.../api/*` paths to `/api/*` automatically).
- 2
Extract the zip and install dependencies
Unzip the archive, then run `pnpm install` (or npm / yarn) in the project folder.
- 3
Fill .env.local
The download includes .env.local placeholders when needed. Add real values for: OPENAI_API_KEY.
- 4
Customize the agent and tool files
Adapt prompts, tools, and stop conditions in the generated project for your product.
- 5
Run the app and open the pattern route
Run `pnpm dev`, open the setup/checklist page if present, then navigate to the generated pattern route and verify responses.

orchestrator-agent/route.tsAPI route wiring the orchestrator agent: uses createAgentUIStreamResponse and validateUIMessages.
lib/orchestrator-agent.tsCore agent definition implementing the Orchestrator-Worker pattern. Defines 9 specialized worker types and a mandatory workflow. Registers 3 tools (orchestrator, worker, coordinator) with stepCountIs(15).
ai-agent-orchestrator-tools/orchestrator.tsOrchestrator planning tool: breaks down requests into structured implementation plans with 6 phases, each with category, priority, complexity, dependencies, and estimated duration.
ai-agent-orchestrator-tools/coordinator.tsCoordinator process management tool: implements 6 actions (start, check_progress, resolve_blocker, complete, pause, resume). Tracks progress and produces completion summaries.
ai-agent-orchestrator-tools/worker.tsWorker execution tool: handles 9 specialized worker types, each producing typed deliverables. Shows the pattern for domain-specific task delegation.
