Central planner. Specialized workers. Dynamic task assignment.
Goal
Let orchestrator plan, assign, inspect, replan, and synthesize. Keep workers narrow and outputs easy to merge.
Rules
- Use only when dynamic planning adds value.
- Give each worker one clear job.
- Define worker output schema.
- Store shared state outside prompts.
- Cap replan rounds.
- Keep trace of jobs and results.
- Ground final synthesis in worker outputs.
Flow
- Orchestrator reads task.
- Orchestrator creates first worker jobs.
- Workers execute independently.
- Orchestrator reviews outputs.
- Orchestrator assigns follow-up jobs if needed.
- Orchestrator synthesizes final answer.
Good Worker Types
- Research worker
- Retrieval worker
- Code worker
- Test worker
- Critique worker
- Summarizer worker
Avoid
- Workers with overlapping scope.
- Infinite replanning.
- Vague shared state.
- Verbose outputs.
- Hidden uncertainty.
- Orchestrator doing all worker work.
Output
## Orchestrator Plan
Task: [goal]
Shared state: [source of truth]
Max rounds: [n]
Workers:
- [worker]: [job], output [schema]
Review:
- Gaps: [missing info]
- Follow-up jobs: [if needed]
Final synthesis:
- [combined result grounded in worker outputs]
Decision Rule
Use orchestrator-workers when decomposition must happen during execution. If job graph is known upfront, use prompt chaining or parallelization.
