crewAI: connect a researcher and reporting analyst
The official README supplies a complete sequential project example: create the project, configure both JSONC agents and dependent tasks, provide model/search credentials, and run it. The source selects openai/gpt-4o and writes to output/report.md. These are source settings and an intended file path, not a generated report or an independently tested run.

#### Example of a simple crew with a sequential process:
```shell
crewai create crew latest-ai-development
cd latest_ai_development
```
Then edit the generated files:
**agents/researcher.jsonc**
```jsonc
{
"role": "{topic} Senior Data Researcher",
"goal": "Uncover cutting-edge developments in {topic}",
"backstory": "You're a seasoned researcher who finds relevant information and presents it clearly.",
"llm": "openai/gpt-4o",
"tools": ["SerperDevTool"],
"settings": {
"verbose": true
}
}
```
**agents/reporting_analyst.jsonc**
```jsonc
{
"role": "{topic} Reporting Analyst",
"goal": "Create detailed reports based on {topic} data analysis and research findings",
"backstory": "You're a meticulous analyst who turns complex data into clear, concise reports.",
"llm": "openai/gpt-4o",
"settings": {
"verbose": true
}
}
```
**crew.jsonc**
```jsonc
{
"name": "Latest AI Development",
"agents": ["researcher", "reporting_analyst"],
"tasks": [
{
"name": "research_task",
"description": "Conduct thorough research about {topic}. Find recent, relevant information.",
"expected_output": "A list with 10 bullet points of the most relevant information about {topic}.",
"agent": "researcher"
},
{
"name": "reporting_task",
"description": "Review the research and expand each topic into a full section for a report.",
"expected_output": "A markdown report with the main topics, each with a full section of information. No fenced code blocks around the whole document.",
"agent": "reporting_analyst",
"context": ["research_task"],
"output_file": "output/report.md",
"markdown": true
}
],
"process": "sequential",
"verbose": true,
"inputs": {
"topic": "AI Agents"
}
}
```
### 3. Running Your Crew
Before running your crew, set the required keys in your `.env` file:
- Your model provider API key — see [LLM setup](https://docs.crewai.com/en/concepts/llms#setting-up-your-llm)
- A [Serper.dev](https://serper.dev/) API key if you use web search: `SERPER_API_KEY=YOUR_KEY_HERE`
Then install dependencies and run from the project directory:
```shell
crewai install
crewai run
```许可

The documented SQLite checkpoint interface displays topic=bing and year=2020. The selected event is task_started; the left tree also lists later events. This previews editable inputs, not completed task output. The exact documented SQLite launch command is supplied below, separately from the two-agent recovery tutorial.

SOFTWARE.crewAI: resume a two-task crew from a checkpoint
This complete source tutorial defines a researcher and writer, enables checkpointing, interrupts after the first task and supplies the restore call. The timestamp/UUID path remains a placeholder to replace with an actual saved checkpoint. MDX wrappers and common indentation are formatted as readable steps; all Python statements are preserved. No task, model call or recovery was executed here.
示例输入
Step 1: Create the crew with checkpointing enabled
```python
from crewai import Agent, Crew, Task
researcher = Agent(role="Researcher", goal="Research", backstory="Expert")
writer = Agent(role="Writer", goal="Write", backstory="Expert")
crew = Crew(
agents=[researcher, writer],
tasks=[
Task(description="Research AI trends", agent=researcher, expected_output="bullets"),
Task(description="Write a summary", agent=writer, expected_output="paragraph"),
],
checkpoint=True,
)
```
Step 2: Run it and interrupt after the first task
```python
result = crew.kickoff()
```
Press `Ctrl+C` after the first task finishes. Look in `./.checkpoints/` — a file named `<timestamp>_<uuid>.json` is the checkpoint.
Step 3: Resume from the checkpoint
```python
from crewai import CheckpointConfig
result = crew.kickoff(
from_checkpoint=CheckpointConfig(
restore_from="./.checkpoints/<timestamp>_<uuid>.json",
),
)

crewAI combines a Python framework for role-based agent teams and stateful Flows with a hosted platform for building and operating enterprise agents.
来源语言 · ENcrewAI 能做什么
- 01Define agents, tools and dependent tasks using JSONC or Python
- 02Orchestrate stateful Flows and restore execution checkpoints
- 03Use hosted visual building, tracing and governance where available
它有什么不同
The MIT-licensed framework can be self-hosted, while visual building and enterprise governance are part of the hosted offering. Teams supply their own model-provider access, tools and runtime configuration.
来源语言 · EN谁值得考虑
- Developers orchestrating multi-agent Python workflows
- Teams evaluating governed enterprise agent operations
需要核对的事项
- 用一个真实任务试用，并对照自己的要求检查结果。
- 核实服务会保存、共享或用于训练哪些数据。
- 在官网确认当前价格、使用限额和取消条款。
官网链接核查于 2026年10月24日；功能声明尚未经过独立测试。
