Nested Team History for Members
===============================

Demonstrates `add_team_history_to_members` for nested teams: when a parent team
delegates to a nested sub-team, the sub-team is given ITS OWN prior history
(filtered by the sub-team's id) rather than the root team leader's history.

Key concept: `add_team_history_to_members=True` injects a text summary of past
runs into each delegated task. For a nested sub-team, that summary is now scoped
to the sub-team, so it can recall what it specifically worked on across turns.

Note: a parent can delegate directly to a leaf agent inside a sub-team, so the
instructions below force delegation to the sub-team as a unit — that is the path
that receives the sub-team's own history.

## Run the Example

<Snippet file="create-venv-step.mdx" />

**1. Install dependencies**

```bash theme={null}
uv pip install -U agno openai sqlalchemy
```

**2. Export your OpenAI API key**

```bash Mac/Linux theme={null}
export OPENAI_API_KEY="your_openai_api_key_here"
```

```bash Windows theme={null}
$Env:OPENAI_API_KEY="your_openai_api_key_here"
```

**3. Run the example**

Save the code above as `nested_team_history_to_members.py`, then run:

```bash theme={null}
python nested_team_history_to_members.py
```
