# CrewAI

> Auto-capture tool calls and results from CrewAI crews.

## Installation

```bash theme={null}
uv add reagent-flow-crewai
```

## Setup

Wrap your crew with `instrument()`:

```python theme={null}
from reagent_flow_crewai import instrument
import reagent_flow

crew = instrument(my_crew)

with reagent_flow.session("crew") as s:
    crew.kickoff()

s.assert_called("my_tool")
```

## How it works

`instrument()` wraps all agent tools to capture calls and results into the active reagent-flow session. The original tool behavior is preserved — if logging fails, a warning is emitted but the tool call still succeeds.

## Example

```python theme={null}
from crewai import Agent, Task, Crew
from crewai_tools import SomeTool
from reagent_flow_crewai import instrument
import reagent_flow

researcher = Agent(
    role="Researcher",
    goal="Find relevant information",
    tools=[SomeTool()],
)

task = Task(
    description="Research Q3 earnings",
    agent=researcher,
)

crew = instrument(Crew(agents=[researcher], tasks=[task]))

with reagent_flow.session("research-crew") as s:
    crew.kickoff()

s.assert_called("some_tool")
s.assert_tool_succeeded("some_tool")
```
