# Orchestration Patterns

> Proven patterns for coordinating multiple agents — from simple fan-out to contract chains for reliable parallel integration.

| Pattern                                                                    | Best for                                               | Key constraint                                                   |
| -------------------------------------------------------------------------- | ------------------------------------------------------ | ---------------------------------------------------------------- |
| [Fan-Out / Fan-In](orchestration-patterns/fan-out-fan-in)                  | Research, independent file analysis, parallel tests    | No shared state between agents                                   |
| [Pipeline Chains](orchestration-patterns/pipeline-chains)                  | Research → implementation, multi-stage migrations      | Each stage must produce structured output                        |
| [Builder-Validator Pairs](orchestration-patterns/builder-validator)        | Correctness-critical work — APIs, security, migrations | Validator must be read-only                                      |
| [Supervisor / Team Lead](orchestration-patterns/supervisor)                | Complex multi-component features                       | Requires [delegate mode](agent-teams#delegate-mode-is-essential) |
| [Contract Chains / Wave Execution](orchestration-patterns/contract-chains) | Full-stack features, parallel work that must integrate | Wave 1 must complete before Wave 2                               |

<Tip>**Choosing the right tool:** Independent work → [`/batch`](parallel-execution#the-batch-command). Report-back only → [subagents](subagent-patterns/). Agents need to coordinate → [Agent Teams](agent-teams/).</Tip>

<Tip>**Official reference** — The [official sub-agents docs](https://docs.anthropic.com/en/docs/claude-code/sub-agents) and [Agent Teams docs](https://docs.anthropic.com/en/docs/claude-code/agent-teams) cover the underlying mechanisms. This page is the pattern taxonomy.</Tip>
