# CrewAI Crew Patterns
|
|
|
|
## Sequential Process
|
|
|
|
Tasks run in order. Each task receives the output of the previous task as context.
|
|
|
|
```python
|
|
from crewai import Crew, Process
|
|
|
|
crew = Crew(
|
|
agents=[researcher, writer, reviewer],
|
|
tasks=[research_task, write_task, review_task],
|
|
process=Process.sequential,
|
|
verbose=True,
|
|
)
|
|
result = crew.kickoff()
|
|
```
|
|
|
|
## Hierarchical Process
|
|
|
|
A manager agent assigns tasks and validates results. Requires `manager_llm`.
|
|
|
|
```python
|
|
from crewai import Crew, Process
|
|
from langchain_openai import ChatOpenAI
|
|
|
|
crew = Crew(
|
|
agents=[researcher, writer, reviewer],
|
|
tasks=[research_task, write_task, review_task],
|
|
process=Process.hierarchical,
|
|
manager_llm=ChatOpenAI(model="gpt-4"), # Required!
|
|
verbose=True,
|
|
)
|
|
```
|
|
|
|
## Crew Parameters
|
|
|
|
| Parameter | Description |
|
|
|-----------|-------------|
|
|
| `agents` | List of agents in the crew |
|
|
| `tasks` | List of tasks to execute |
|
|
| `process` | `Process.sequential` or `Process.hierarchical` |
|
|
| `manager_llm` | Required for hierarchical. LLM for the manager agent |
|
|
| `verbose` | Print detailed execution logs |
|
|
| `memory` | Enable cross-agent memory |
|
|
| `cache` | Enable tool result caching |
|
|
| `planning` | Enable planning step before execution |
|
|
| `max_rpm` | Rate limit across the crew |
|
|
|
|
## Key Gotchas
|
|
|
|
- **Hierarchical without `manager_llm` fails silently.** The crew appears to run but produces no output.
|
|
- **Sequential with more than 4-5 agents** can produce very long completion times (each agent waits for the previous).
|
|
- **Crew-level `memory=True** enables agents to remember context across tasks.
|
|
- **Tool caching** (`cache=True`) prevents repeated API calls for the same input.
|
|
- **`crew.kickoff()` is synchronous** by default. For async, check the async API.
