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
Use cases
Products and workflows this pattern is designed to support.
- Software project coordination agents
- Product development task orchestration
- Research project managers with specialist workers
- QA and deliverable tracking copilots
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
Install from the preview toolbar
Copy the install command above and run it in your project — Pro patterns include a short-lived token.
- 2
Add environment variables to .env.local
OPENAI_API_KEY
- 3
Point client fetches at your API routes
Replace preview `/view/.../api/...` paths with `/api/...` in the installed files.
- 4
Customize the agent and tool files
Adapt prompts, tools, and stop conditions for your product — Copy for AI in the toolbar helps seed that work.
- 5
Run your dev server and open the pattern route
Install dependencies if needed, then start the app 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.
ai-agent-orchestrator-tools/schema.tsShared Zod schemas defining data contracts between orchestrator, workers, and coordinator.
