This example show how you can add Composio tools .

First, make sure you have Composio and some of the extras downloaded.
```
poetry install --extras "external-tools"
```
then setup letta with `letta configure`.

Aditionally, this example stars a Github repo on your behalf. You will need to configure Composio in your environment.
```
composio login
composio add github
```
